\title Session Management in Qt Creator
In Qt Creator, a session is a collection of:
\list
\o open projects together with their dependencies,
\o open editors,
\o breakpoints and watches, as well as
\o bookmarks
\endlist
When you run Qt Creator, you have a default session. You can create a new
session using the \gui{Session Manager...} option, available in the
\gui{File -> Session} menu.
\image qtcreator-session-manager.png
To switch between sessions, select \gui{File -> Session}. If you do not
create and select any session, Qt Creator will always use the default
session.
\image qtcreator-session-menu.png
When you launch Qt Creator, a list of your recent sessions will be
displayed on the \gui{Welcome Screen}.

\section1 Introduction
Qt Creator does not have its own debugger. Instead, it provides a graphical
frontend to various debugger engines:

\o Platform
\o Compiler
\o Debugger Engine

\o Debugging Tools for Windows/Microsoft Console Debugger (CDB)
step through a program line-by-line or instruction-by-instruction,
interrupt running programs, set breakpoints, examine the contents of the
call stack, local and global variables, etc.
Within Qt Creator, the raw information provided by the engine is displayed
in a clear and concise manner, simplifying the process of debugging.
In addition to generic IDE functionality: stack view, views for locals and
watchers, registers, etc, Qt Creator comes with additional features to make
debugging Qt-based applications easy. The debugger frontend knows about the
internal layout of several Qt classes such as QString, the QTL containers,
and most importantly QObject (and classes derived from it), as well as
most containers of the C++ Standard Library, and is therefore able to
present their contents in a useful way.
\section1 Debugger Engine Installation Notes

\o Using this engine requires you to install the
\e{Debugging Tools for Windows}
\l{http://www.microsoft.com/whdc/devtools/debugging/installx86.Mspx}{32-bit}
or
\l{http://www.microsoft.com/whdc/devtools/debugging/install64bit.Mspx}{64-bit}
package (Version 6.11.1.404 for the 32-bit or the 64-bit version of Qt Creator, respectively),

\endtable
\section1 Interacting with the Debugger
In \gui Debug mode, several dock widgets are used to interact with the
program you are debugging. The frequently used dock widgets are visible by
default; the rarely used ones are hidden. To change the default settings,
select \gui Debug and then select \gui View.
Here, you can lock or unlock the location of your views as well as display
or hide them. Among the views you can display are \gui Breakpoints,
\gui Disassembler, \gui Modules, \gui Registers, \gui Debugger, \gui Stack, and
\gui Thread. The position of your dock widgets will be saved for future
sessions.
\section2 Breakpoints
Breakpoints are shown in the \gui{Breakpoints} view which is enabled by
by default. This view is also accessible when the debugger and the program
being debugged is not running.
A breakpoint represents a position or sets of positions in the code that,

Kavindra Devi Palaraja
committed
when executed, interrupts the program being debugged and passing the
control to the user. The user is then free to examine the state of the
interrupted program, or continue execution line-by-line or continuously.
Typically, breakpoints are associated with a source code file and line, or
the start of a function -- both allowed in Qt Creator.
Also, the interruption of a program by a breakpoint can be restricted with
certain conditions.
You can set a breakpoint:
\list
\o At a particular line you want the program to stop -- click on the
left margin or press \key F9 (\key F8 for Mac OS X).

Kavindra Devi Palaraja
committed
\o At a function that you want the program to interrupt -- enter the
function's name in \gui{Set Breakpoint at Function...} under the

\gui Debug menu.
\endlist
You can remove a breakpoint:
\list
\o By clicking on the breakpoint marker in the text editor.
\o By selecting the breakpoint in the breakpoint view and pressing
\key{Delete}.
\o By selecting \gui{Delete Breakpoint} from the breakpoint's context
menu in the \gui Breakpoints view.
\endlist
Breakpoints can be set and deleted before the program has actually started
running or while it is running under the debugger's control. Also,
breakpoints are saved together with a session.
\section2 Running
To start a program under the debugger's control, select the \gui{Debug}
menu and \gui{Start Debugging}, or simply press \key{F5}. Qt Creator then
checks whether the compiled program is up-to-date, rebuilding it if
necessary. The debugger then takes over and starts the program.

Kavindra Devi Palaraja
committed
\note Starting a program in the debugger can take considerable amount of
time, typically in the range of several seconds to minutes if complex

Once the program starts running, it behaves as usual; performance-wise as
well. The user can interrupt a running program by selecting
\gui {Interrupt} from the \gui{Debug} menu. The program is automatically
interrupted as soon as a breakpoint is hit.
Once the program stops, Qt Creator:
\list
\o Retrieves data representing the call stack at the program's current
position.
\o Retrieves the contents of local variables.
\o Examines \gui Watchers.
\o Updates the \gui Registers, \gui Modules, and \gui Disassembler
views.
\endlist
You can use the debugger views to examine the data in more detail.
To finish debugging, Press \key{Shift+F5}. A line of code can be executed
as a whole with \key F10; to execute a function or a sub-function, use
\key F11. Alternatively, you can continue running the program with \key F5.

Kavindra Palaraja
committed
It is possible to continue executing your program until the current
function completes or jump to an arbitrary position in the current
function.

Kavindra Devi Palaraja
committed
When the program being debugged is interrupted, Qt Creator displays the
nested function calls leading to the current position as a \e call stack
trace. This stack trace is built up from \e{call stack frames}, each
representing a particular function. For each function, Qt Creator will try
to retrieve the file name and line number of the corresponding source
files. This data is shown in the \gui Stack view.
\image qtcreator-debug-stack.png
Since the call stack leading to the current position may originate or go
through code for which no debug information is available, not all stack
frames will have corresponding source locations. These frames will be

Kavindra Devi Palaraja
committed
grayed out in the \gui Stack view.
If you click on a frame with a known source location, the text editor will
jump to the corresponding location and update the \gui{Locals and Watchers}

Kavindra Devi Palaraja
committed
view, making it seem like the program was interrupted before entering the
function.

Kavindra Devi Palaraja
committed
If a multi-threaded program is interrupted, the \gui Thread view or the
combobox named \gui Thread in the debugger's status bar can be used to
switch from one thread to another. The \gui Stack view will adjust itself
accordingly.
\section2 Locals and Watchers
Whenever a program stops under the control of the debugger, it retrieves
information about the topmost stack frame and displays it in the
\gui{Locals and Watchers} view. This typically includes information about
parameters of the function in that frame as well as the local variables.
Compound variables of struct or class type will be displayed as
"expandable" in the view. Click on the "+" to expand the entry and show
all members. Together with the display of value and type, the user can
examine and traverse the low-level layout of an object's data.
\table

\i \bold{Note:}

\i Gdb, and therefore Qt Creator's debugger works for optimized
builds on Linux and Mac OS X. However, optimization may lead
to re-ordering of instructions or sometimes even complete
removal of some local variables. In this case, the
\gui{Locals and Watchers} view may show unexpected data.

Kavindra Devi Palaraja
committed
\row
\i The debug information provided by gcc does not include enough
information about the time when a variable is initialized.
Therefore, Qt Creator can not tell whether the contents of a
local variable contains "real data", or "initial noise". If a
QObject appears uninitialized, its value will be reported as
"out of scope". However, not all uninitialized objects can be
recognized as such.
The \gui{Locals and Watchers} view also provides access to the most
powerful feature of the debugger: comprehensive display of data belonging
to Qt's basic objects. To enable this feature, select \gui{Use
debugging helper} from the \gui Debug menu.The
\gui{Locals and Watchers} view will be re-organized to provide a high-level
view of the objects. For example, in case of QObject, instead of displaying
a pointer to some private data structure, you will see a list of children,
signals and slots.
Similarly, instead of displaying many pointers and integers, Qt Creator's
debugger will display the contents of a QHash or QMap in an orderly manner.
Also, the debugger will display access data for QFileInfo and provide
access to the "real" contents of QVariant.
The \gui{Locals and Watchers} view can be used to change the contents of
variables of simple data types such as \c int or \c float when the program

Kavindra Devi Palaraja
committed
is interrupted. To do so, click on the \gui Value column, modify the value
with the inplace editor, and hit \key Enter (or \key Return).

Kavindra Devi Palaraja
committed
\note The set of watched items is saved within your session.
By default, the \gui Modules view is hidden as it is only useful with the

Kavindra Palaraja
committed
experimental delayed loaing of debug information feature. You can turn

Kavindra Devi Palaraja
committed
this feature on by selecting \gui{Fast Debugger Start}

Kavindra Palaraja
committed

Kavindra Palaraja
committed
With this feature, debug information from the Qt library itself is not
loaded when the application starts up, thereby reducing the startup times
for some applications. You can then use the \gui Modules view to manually
load this information, if required.

Kavindra Devi Palaraja
committed
\note In this scenario, some breakpoints may not be triggered by the
debugger.

Kavindra Palaraja
committed

Kavindra Palaraja
committed
By default, both the \gui Disassembler and \gui Registers view are hidden.
The \gui Disassembler view displays disassembled code for the current
function; the \gui Registers view displays the current state of the CPU's
registers. Both views are useful for low-level commands such as
\gui{Step Single Instruction} and \gui{Step Over Single Instruction}.
\section1 Debugging Helper Library
While debugging Qt Creator dynamically loads a helper library into your
program. This helper library enables Qt Creator to pretty print Qt and STL
types. The Qt SDK package already contains a prebuilt debugging helper
library. To create a debugging helper library, select the \gui{Options}
from the \gui{Tools} menu, and go to the \gui{Qt/Qt Versions} pane. As the
internal layout of qt can change between versions, the debugging helper
library is built for each Qt version.
\section1 A Walkthrough for the Debugger Frontend
In our \l{Writing a Simple Program with Qt Creator}{TextFinder} example, we
read a text file into a QString and then display it with a QTextEdit.
Suppose, you would like to look at this QString, \c{line}, and see what
data it actually stores. Follow the steps described below to place a
breakpoint and view the QString object's data.
\i \inlineimage qtcreator-setting-breakpoint1.png
\i \bold{Setting a Breakpoint}
First, we set a breakpoint on the line where we invoke
\l{http://doc.trolltech.com/qtextedit.html#plainText-prop}{setPlainText()}
by clicking between the line number and the window border. Then, select
\gui{Start Debugging} from the \gui{Debug} menu or press \key{F5}.
\endtable
Breakpoints are visible in the \gui{Breakpoints} view, shown below, in
\gui{Debug} mode. If you wish to remove a breakpoint, simply right-click on
it and select \gui{Delete breakpoint} from the context menu.
\image qtcreator-setting-breakpoint2.png
To view the contents of \c{line}, take a look at the \gui{Locals and
Watchers} view.
\image qtcreator-watcher.png
Suppose we modify our \c{on_findButton_clicked()} function to move back to
the start of the document and continue searching once the cursor hits the
end of the document. Adding this functionality can be done with the code
snippet below:
QString searchString = ui->lineEdit->text();
QTextDocument *document = ui->textEdit->document();
QTextCursor cursor = ui->textEdit->textCursor();
cursor = document->find(searchString, cursor,
QTextDocument::FindWholeWords);
ui->textEdit->setTextCursor(cursor);

Kavindra Devi Palaraja
committed
if (!found && previouslyFound) {
int ret = QMessageBox::question(this, tr("End of Document"),
tr("I have reached the end of the document. Would you like "
"me to start searching from the beginning of the document?"),
QMessageBox::Yes | QMessageBox::No, QMessageBox::Yes);
if (ret == QMessageBox::Yes) {
cursor = document->find(searchString,
QTextDocument::FindWholeWords);
ui->textEdit->setTextCursor(cursor);
} else
return;
}
previouslyFound = found;
}
\endcode
However, if you compile and run this code, the application will not work
correctly due to a logic error. To locate this logic error, you can step
through the code using the following buttons:

\title CMake Support in Qt Creator
Since Qt Creator 1.1, support for \c CMake project files is available.
Qt Creator 1.3 supports the Microsoft Toolchain if the cmake version
is at least 2.8.
\section1 Opening CMake Projects

Kavindra Devi Palaraja
committed
To open a \c CMake project select \gui Open from the \gui File menu and
select the \c{CMakeLists.txt} file from your \c CMake project. A wizard
will guide you with the rest of the process. If the \c CMake project does
not have an in-place build, Qt Creator lets you specify the directory in
which the project is built (shadow build).
\image qtcreator-cmake-import-wizard1.png
The screenshot below shows how you can specify command line arguments to

Kavindra Devi Palaraja
committed
\c CMake for your project.
\image qtcreator-cmake-import-wizard2.png

Kavindra Devi Palaraja
committed
Normally, there is no need to pass any command line arguments for projects

Kavindra Devi Palaraja
committed
that are already built, as \c CMake caches that information.
\section1 Building CMake Projects
Qt Creator builds \c CMake Projects by running \c make, \c mingw32-make, or
\c nmake depending on your platform. The build errors and warnings are
parsed and displayed in the \gui{Build Issues} output pane.
By default Qt Creator builds the \e{all} target. You can specify which
targets to build in \gui{Project} mode, under \gui{Build Settings}.
\image qtcreator-cmake-build-settings.png
Qt Creator supports multiple build configurations. Also, the build
directory can be modified after the initial import.
\section1 Running CMake Projects
Qt Creator automatically adds \gui{Run Configurations} for all targets
specified in the \c CMake project file.

\title Support for Generic Projects in Qt Creator
Since Qt Creator 1.1, generic projects are supported, in addition to
\c qmake projects. In other words, you can import existing projects that do
not use \c qmake or \c CMake and Qt Creator will simply ignore your build
system.

Kavindra Devi Palaraja
committed
This feature lets you use Qt Creator as a code editor. You can change the
way your project is built by modifying the \c make command under
\gui{Build Settings} in the \gui{Projects} mode.
For a generic project, you have to manually specify which files belong to
your project and which include directories/defines you want to pass to your
compiler.
\section2 Specifying Files
The list of files for a generic project is specified in the \c{.files}
file. When you first create a generic project, Qt Creator will add any
files it recognizes to your project. To add or remove files later, simply
edit the \c{.files} file in Qt Creator. Your project tree will be refreshed
when you save this file. You can also add or remove files using the context
menu in the project tree.
If you frequently need to update the \c{.files} file, we recommend the use
of a small script that will update the files for you. Currently, if the
file is modified externally, Qt Creator must be restarted for the changes
to take effect.
\section2 Specifying Include Paths
The include paths are specified in the \c{.includes} file, one include
path per line. The paths can be either absolute or relative to the
\c{.includes} file.
\section2 Specifying Defines
The defines are specified in the \c{.config} file. This file is a regular
C++ file, prepended to all your source files when they are being parsed.
However, you should only use it to add lines like the following:
\code
#define NAME value
\endcode
\section2 Creating a Run Configuration

Kavindra Devi Palaraja
committed
Qt Creator cannot automatically determine which executable it should run.
To set up a custom executable run configuration in the \gui Projects mode,
use the \bold{Add} button. Here you can specify the name, executable, and
some optional arguments. By default, the working directory is
\c{$BUILDDIR} which should work fine.

\title Development of Qt for Symbian Based Applications
Qt Creator 1.3 comes with preliminary support for development of
applications using Qt for the Symbian Platform.
\e{Note that this is highly experimental, and not intended for production use.
The primary aim is to allow Symbian developers to familiarize themselves with Qt Creator
and provide feedback that will help us improve Symbian support in future versions of
Qt Creator.}
Please provide us with feedback, using the mailing list or IRC, as described on the
\l{http://qt.gitorious.org/qt-creator/pages/Home}{Qt Creator Development Wiki}.
\section2 Getting Started
You need the following software installed on your PC.
Only Windows development is supported.
\list
\o \l{http://www.forum.nokia.com/main/resources/tools_and_sdks/S60SDK/}
{S60 Platform SDK 3rd Edition FP1 or higher}
\o \l{http://www.forum.nokia.com/main/resources/technologies/openc_cpp/}
{Open C/C++ v1.6.0 or higher.} Install this to all S60 SDKs you plan to use Qt with.
This is included in the Qt for Symbian binary installers.
\o Either the GCCE Arm Toolchain that is included in the S60 Platform SDKs, or
RVCT 2.2 [build 686] or later (which is not available free of charge).
Your environment needs to find the compiler in the PATH.
\o Qt for Symbian 4.6.0, installed into the S60 SDKs you want to use.
\endlist
And for deploying and running applications on the device
\list
\o The Nokia USB drivers that come e.g. with PC Suite.
\o The \l{http://tools.ext.nokia.com/trk/}{App TRK} application for your device.
\endlist
Running Qt based applications on real devices requires the following packages to be installed on
your device. The packages can be found in the S60 SDK where you installed Open C/C++:
\list
\o nokia_plugin\\openc\\s60opencsis\\pips_s60_\<version\>.sis
\o nokia_plugin\\openc\\s60opencsis\\openc_ssl_s60_\<version\>.sis
\o nokia_plugin\\opencpp\\s60opencppsis\\stdcpp_s60_\<version\>.sis
\endlist
If you want to run your applications in the Symbian Emulator, you also need to install
Carbide.c++ v2.0.0 or higher.
\section2 Setting up Qt Creator
When you run Qt Creator after installing the S60 Platform SDK and Qt for Symbian,
the installed SDKs and their corresponding Qt versions are automatically detected.
For each detected S60 SDK with Qt, a special entry is made in the Qt Version Management settings
\gui{Tools -> Options... -> Qt4 -> Qt Versions}.
\e{Note that if you manually add a Qt version for Symbian, you must
also manually specify the S60 SDK to use for this version.}
\image qtcreator-qt4-qtversions-win-symbian.png
If you want to run your applications in the Symbian Emulator, you need to point Qt Creator
to the Metrowerks Compiler that you want to use, by setting the \gui{Carbide Directory}
of the Qt version to the corresponding Carbide.c++ installation directory.
You can check what S60 SDKs and corresponding Qt versions are found in the
\gui{Tools -> Options... -> Qt4 -> S60 SDKs} preference page.

After installing all the prerequisites and checking the setup in Qt Creator as described
above, you need to make some settings for your project.
\e{Note that the only supported build system for Qt for Symbian applications in Qt Creator
is qmake.}
Before you can build your project for the Symbian Platform you need to create build
configurations for it.
Open \gui{Projects mode} and make sure that your project is selected for editing in
\gui{Edit Project Settings for Project ...}. Add debug and release build configurations
for the Symbian target by selecting the corresponding Qt version from the build configuration
\gui{Add} menu.
\image qtcreator-symbian-add-buildconfiguration.png
The created build configurations default to using the GCCE tool chain. If you want to build
for the device using RVCT, or for the Symbian Emulator using WINSCW, change the tool chain in
the \gui{General} section of the build configuration settings (press the \gui{Show Details}
button first).
Now you can switch to building your project for the device by selecting one of the
new build configurations as the active configuration at the top of \gui{Projects mode}.
\image qtcreator-symbian-change-buildconfiguration.png
\section2 Running your Project
\section3 Running your Project in the Emulator
Similar to the build configuration setup for your project you need to create a run
configuration for running your project in the Symbian emulator: Switch to \gui{Projects mode}
and in \gui{Run Settings} you will find the \gui{Add -> YourApplication in Symbian Emulator}
button.
\image qtcreator-symbian-add-run-in-emulator.png
To start your project in the emulator select this run configuration as the active configuration
at the top of \gui{Projects mode} and press the run button.
\image qtcreator-symbian-change-run-in-emulator.png
\section3 Running your Project on the Device
To run your project on a real Symbian device, just add another run configuration in
\gui{Projects mode} via \gui{Run Settings}, \gui{Add -> YourApplication on Symbian Device} button.
\image qtcreator-symbian-add-runconfiguration.png
\image qtcreator-symbian-details-runconfiguration.png
In the details of the run configuration you can specify a certificate to use, and
select one of the devices that you have currently attached to your computer.
The only connection mode supported at the moment is USB in \e{PC Suite} mode.
For actually running your application on the device, you need to set the device run configuration
as the active configuration at the top of \gui{Projects mode}.
Start the \gui{App TRK} application on your device and press the run button to create
a package for your application, deploy, install and run it automatically on your device.

\section2 Troubleshooting
When something goes wrong check the following things:
\list
\o Did you build your application with a Qt version for Symbian?
\o Are the settings for the Qt version you use to build your project correct? Check the
path to the S60 SDK, and if you need to specify the path to your compiler tool chain.
\o Is the emulator/device run configuration selected as the active run configuration?
\o Did you build using the right toolchain, i. e. WINSCW for running in the Emulator,
GCCE or RVCT for running on the device?
\o If the emulator process could not be started, try closing Creator and starting the
application directly from your file manager. Having done this, Creator should be
able to run your projects in the Emulator.
\o Is the device connected via USB in \e{PC Suite} mode?
\o Is App TRK running on the device, using the USB connection, and does it have status
\e{connected}?
\o Is your device detected and selected in the run configuration details?
\endlist
If neither of this helps to solve your problem, search the qt-creator@trolltech.com
mailinglist archives or provide feedback to us via the methods described on the
\l{http://qt.gitorious.org/qt-creator/pages/Home}{Qt Creator Development Wiki}.

\title Handling External Libraries
The ability to recognize external libraries is not only important for the
underlying build system, but also for Qt Creator itself. This ability
allows Qt Creator to support code completion and syntax highlighting for
external libraries as if they were part of the current project or the Qt
library.
The procedure of adding a library to a project, depends on the type of
project, which influences the build system used. The following sections
describe the the procedure required for each project type.
\section1 QMake Projects (the default)
Open your project file (\c{.pro}) from the \gui{Projects} pane. Then,
follow the guidelines in the
\l{http://doc.trolltech.com/latest/make-project-files.html#declaring-other-libraries}
{Declaring other Libraries} section of the Qt documentation.
If your project successfully builds and links against the external library,
syntax completion and highlighting should work.
\section1 CMake Projects
In CMake, libraries are usually detected using the \c{FIND_PACKAGE()}
macro. A couple of them are already being shipped with CMake, they can be
found in the \c{Modules} directory of your CMake installation. If you
provide libraries on your own, you will need to provide your own
\c{FindFoo.cmake} file. Refer to the
\l{http://vtk.org/Wiki/CMake_FAQ#Writing_FindXXX.cmake_files}{CMake FAQ}
for details.
As with \c qmake projects, syntax completion and highlighting should work
if you can sucessfully build and link against the external library.
\section1 Generic Projects
If you import a project using the \e{Generic Projects} function, Qt Creator
will create a file called \c{<projectname>.includes} in your project root
directory. This file contains all project subdirectories which Qt Creator
could find relevant headers for. Simply add your include pathes here.
In \gui{Generic Project} mode, Qt Creator will not modify any project
settings, so the above is merely a hint for code completion and syntax
highlighting.

\bold{Quickly Switching between Modes}
You can quickly switch between modes by pressing \key{Ctrl+1},
Qt Creator provides a lot of useful keyboard shortcuts. Some useful
shortcuts can be found \l{Keyboard Shortcuts}{here}.
\bold{Running Qt Creator from the Command Line}
You can start Qt Creator from a command prompt with the name of an existing
session or \c{.pro} file by giving the name as argument on the command
line.
You can show and hide the the sidebar in \gui Edit and \gui Debug mode by
clicking on the corresponding icon, or by pressing \key{Alt+0} (Mac OS X:
\key{Cmd+0}).
If you have an instance of a class that is derived from QObject, and you
would like to find all other objects connected to one of your object's
slots using Qt's signals and slots mechanism -- you can enable
\gui{Use Custom Display for Qt Objects} feature under the \gui Debug menu.
In the \gui{Locals and Watchers} view, expand the object's entry and open
the slot in the \e slots subitem. The objects connected to this slot are
exposed as children of the slot. This method works with signals too.

If special debugging of Qt objects fails due to data corruption within the
debugged objects, you can switch the debugging helpers off in the
\gui{Debugger -> Debugging Helper} options dialog.
This will make the low-level structures visible again.

\target glossary-shadow-build
\o Shadow building means building a project in a separate
directory, the \e{build directory}. The build directory is
different from the source directory. One of the benefits of
shadow building is that it keeps your source directory clean.
Shadow building is the best practice if you need many build
configurations for a single set of source.
