\c{textfinder.cpp}. We begin by filling in the functionality to load a
text file. The code snippet below describes this:
- \code
- void TextFinder::loadTextFile()
- {
- QFile inputFile(":/input.txt");
- inputFile.open(QIODevice::ReadOnly);
-
- QTextStream in(&inputFile);
- QString line = in.readAll();
- inputFile.close();
-
- ui->textEdit->setPlainText(line);
- QTextCursor cursor = ui->textEdit->textCursor();
- }
- \endcode
+ \quotefromfile textfinder.cpp
+ \skipto TextFinder::loadTextFile
+ \printuntil }
Basically, we load a text file using
\l{http://doc.trolltech.com/qfile.html}{QFile}, read it with
\l{http://doc.trolltech.com/qtextstream.html}{QTextStream}, and
then display it on \c{textEdit} with
- \l{http://doc.trolltech.com/qtextedit.html#plainText-prop}{setPlainText()}.
+ \l{http://doc.trolltech.com/qtextedit.html#plainText-prop}{setPlainText()}
+ which requires adding the following additional #includes to textfinder.cpp:
+ \code
+ #include <QtCore/QFile>
+ #include <QtCore/QTextStream>
+ \endcode
For the \c{on_findButton_clicked()} slot, we extract the search string and
use the \l{http://doc.trolltech.com/qtextedit.html#find}{find()} function
to look for the search string within the text file. The code snippet below
further describes it:
- \code
- void TextFinder::on_findButton_clicked()
- {
- QString searchString = ui->lineEdit->text();
- ui->textEdit->find(searchString, QTextDocument::FindWholeWords);
- }
- \endcode
+ \quotefromfile textfinder.cpp
+ \skipto on_findButton_clicked
+ \printuntil }
Once we have both these functions complete, we call \c{loadTextFile()} in
our constructor.
- \code
- TextFinder::TextFinder(QWidget *parent)
- : QWidget(parent)
- {
- ui->setupUi(this);
- loadTextFile();
- }
- \endcode
+ \quotefromfile textfinder.cpp
+ \skipto TextFinder::TextFinder
+ \printuntil }
The \c{on_findButton_clicked()} slot will be called automatically due to
this line of code:
