called Button.qml (for example).
\note Components are listed in the \gui Library pane only if the filename begins
with a capital letter.
\o Double-click the file to open it in the code editor.
\o Click \gui {Design} to edit the file in the visual editor.
\o Drag and drop a \gui Rectangle from the \gui Library pane to the scene.
\o In the \gui Properties pane, modify the appearance of the button.
\list a
\o In the \gui Color field, select the button color.
\o In the \gui Radius field, use
the slider to set the radius of the rectangle and produce rounded corners for the button.
\endlist
\o Drag and drop a \gui {Text} item on top of the \gui Rectangle. This creates a
nested element where \gui Rectangle is the parent element of \gui Text. Elements
are positioned relative to their parents.
\o In the \gui Properties pane, edit the properties of the \gui Text item.
\list a
\o In the \gui Text field, type \bold Button.
You can select the text color, font, size, and style in the \gui Font section.
\o In the \gui Alignment field, select the center button to align the text to the
center of the button.
\o Click \gui {Geometry}, and then click the
\inlineimage qmldesigner-anchor-fill-screen.png
button to anchor the text to the whole button area.
\endlist
\o Click \gui Edit to edit the \c width and \c height properties of the button
to fit the button size.
\o Press \key {Ctrl+S} to save the button.

\title Creating Scalable Buttons and Borders
You can use the \l{http://doc.qt.nokia.com/4.7-snapshot/qml-borderimage.html}{Border Image}
element to display an image, such as a PNG file, as a border and a background.
Use two Border Image elements and suitable graphics to make it look like the button
is pushed down when it is clicked. One of the Border Image elements is visible by default.
You can specify that it is hidden and the other one becomes visible when the mouse is clicked.
Add a MouseArea that covers the whole area and emits the clicked signal (\c {parent.clicked()})
when it detects a mouse click.
You can add text to the button and set it up as a property. The text can then be initialized
from the outside, making the button a reusable UI component. The font size is also available in case
the default size is too big. You can scale down the button text and use smooth text rendering
for some extra quality.
\image qmldesigner-borderimage.png "Graphical button"
To create a graphical button:
\list 1
\o Select \gui {File > New File or Project > Qt > Qt QML File} to create a QML file

following code snippet:
\code
Item {

\endcode
\o Click \gui {Design} to edit the file in the visual editor.
\o Drag and drop two \gui BorderImage items from the \gui Library pane to
the scene.
\o Drag and drop a \gui Text item to the scene.
\o Drag and drop a \gui MouseArea to the screen.
\o Click \gui Edit to specify properties for the \gui Item, as
illustrated by the following code snippet:
\code
property string text: ""
property int fontSize: 44
signal clicked
\endcode
\o In the \gui Navigator view, select \gui borderimage1 to specify
settings for it in the \gui Properties pane:
\list a
\o In the \gui Source field, select the image file for the
button, for example button_up.png.
\o In the \gui Left, \gui Right, \gui Top, and \gui Bottom fields,
enter 32 to set the margins for the image.
\o Click \gui {Geometry}, and then click the
\inlineimage qmldesigner-anchor-fill-screen.png
button to anchor the border image to the \gui Item.
\o Click \gui Advanced, and select \gui {Set Expression} in the menu
next to the \gui Visibility check box.

\title Creating List Views
You use list views and list models to create lists. You use delegates to handle list items.
Typically, the list model is provided by a QAbstractListModel C++ model object,
but you can also create it in QML.

\o Select \gui {File > New File or Project > Qt > Qt QML File} to create a QML file
called ListView.qml (for example).
\o Double-click the file to open it in the code editor.
\o Add a list model that contains the data to be shown on the list, as
illustrated by the following code snippet:
\code
import Qt 4.7
Rectangle {
width: 360
height: 640
ListModel {
id: myListModel
ListElement {
item_index: 0
item_name: "Item 1"
item_description: "Description 1"
}
ListElement {
item_index: 1
item_name: "Item 2"
item_description: "Description 2"
}
ListElement {
item_index: 2
item_name: "Item 3"
item_description: "Description 3"
}
}
\endcode
\o Add a delegate that draws each item in the list.
\code
Component {
id: myListDelegate
Item {
id: wrapper
width: parent.width
height: 40
Column {
x: 5; y: 5
Text { text: '<b>Name:</b> ' + item_name }
Text { text: '<b>Descriptionr:</b> ' + item_description }
}
MouseArea {
anchors.fill: parent
onClicked: myList.currentIndex = item_index
}
}
}
\endcode
You can use a separate delegate to hilight the currently selected item.
\code
Component {
id: myListHilight
Rectangle {
width: parent.width
height: 40
color: "lightsteelblue"
radius: 5
SpringFollow on y {
to: myList.currentItem.y
spring: 3
damping: 0.2
}
}
}
\endcode
\o Add the list view, as illustrated by the following code snippet:
\code
ListView {
id: myList
width: parent.width; height: parent.height
model: myListModel
delegate: myListDelegate
highlight: myListHilight
focus: true
}
}
