Drawer QML Type▲
-
Import Statement: import QtQuick.Controls
-
Inherits: Popup
-
Group: Drawer is part of qtquickcontrols-navigation, qtquickcontrols-popups
Detailed Description▲
Drawer provides a swipe-based side panel, similar to those often used in touch interfaces to provide a central location for navigation.
Drawer can be positioned at any of the four edges of the content item. The drawer above is positioned against the left edge of the window. The drawer is then opened by "dragging" it out from the left edge of the window.
import
QtQuick
import
QtQuick.Controls
ApplicationWindow {
id
:
window
visible
:
true
Drawer {
id
:
drawer
width
:
0.66
*
window.width
height
:
window.height
Label {
text
:
"Content goes here!"
anchors.centerIn: parent
}
}
}
Drawer is a special type of popup that resides at one of the window edges. By default, Drawer re-parents itself to the window overlay, and therefore operates on window coordinates. It is also possible to manually set the parent to something else to make the drawer operate in a specific coordinate space.
Drawer can be configured to cover only part of its window edge. The following example illustrates how Drawer can be positioned to appear below a window header:
import
QtQuick
import
QtQuick.Controls
ApplicationWindow {
id
:
window
visible
:
true
header
:
ToolBar {
}
Drawer {
y
:
header.height
width
:
window.width *
0.6
height
:
window.height -
header.height
}
}
The position property determines how much of the drawer is visible, as a value between 0.0 and 1.0. It is not possible to set the x-coordinate (or horizontal margins) of a drawer at the left or right window edge, or the y-coordinate (or vertical margins) of a drawer at the top or bottom window edge.
In the image above, the application's contents are "pushed" across the screen. This is achieved by applying a translation to the contents:
import
QtQuick
import
QtQuick.Controls
ApplicationWindow {
id
:
window
width
:
200
height
:
228
visible
:
true
Drawer {
id
:
drawer
width
:
0.66
*
window.width
height
:
window.height
}
Label {
id
:
content
text
:
"Aa"
font.pixelSize: 96
anchors.fill: parent
verticalAlignment
:
Label.AlignVCenter
horizontalAlignment
:
Label.AlignHCenter
transform
:
Translate {
x
:
drawer.position *
content.width *
0.33
}
}
}
If you would like the application's contents to stay where they are when the drawer is opened, don't apply a translation.
Drawer can be configured as a non-closable persistent side panel by making the Drawer non-modal and non-interactive. See the Side Panel example for more details.
On some platforms, certain edges may be reserved for system gestures and therefore cannot be used with Drawer. For example, the top and bottom edges may be reserved for system notifications and control centers on Android and iOS.

edge : enumeration▲
This property holds the edge of the window at which the drawer will open from. The acceptable values are:
Constant |
Description |
---|---|
Qt.TopEdge |
The top edge of the window. |
Qt.LeftEdge |
The left edge of the window (default). |
Qt.RightEdge |
The right edge of the window. |
Qt.BottomEdge |
The bottom edge of the window. |
[since QtQuick.Controls 2.2 (Qt 5.9)] interactive : bool▲

The default value is true.
This property was introduced in QtQuick.Controls 2.2 (Qt 5.9).

position : real▲
This property holds the position of the drawer relative to its final destination. That is, the position will be 0.0 when the drawer is fully closed, and 1.0 when fully open.
