\brief Provides a top-level application window.
\image applicationwindow.png
ApplicationWindow is a \l Window that adds convenience for positioning items,
such as \l MenuBar, \l ToolBar, and \l StatusBar in a platform independent
manner.
\code
ApplicationWindow {
id: window
visible: true
menuBar: MenuBar {
Menu { MenuItem {...} }
Menu { MenuItem {...} }
}
toolBar: ToolBar {
RowLayout {
anchors.fill: parent
ToolButton {...}
}
}
TabView {
id: myContent
anchors.fill: parent
...
}
}
\endcode
\note By default, an ApplicationWindow is not visible.
The \l{Qt Quick Controls - Gallery} example is a good starting
point to explore this type.
*/
Window {
id: root
/*!
\qmlproperty MenuBar ApplicationWindow::menuBar
This property holds the \l MenuBar.
By default, this value is not set.
*/
property MenuBar menuBar: null
/*!
\qmlproperty Item ApplicationWindow::toolBar
This property holds the toolbar \l Item.
It can be set to any Item type, but is generally used with \l ToolBar.
By default, this value is not set. When you set the toolbar item, it will
be anchored automatically into the application window.
*/
property Item toolBar
/*!
\qmlproperty Item ApplicationWindow::statusBar
This property holds the status bar \l Item.
It can be set to any Item type, but is generally used with \l StatusBar.
By default, this value is not set. When you set the status bar item, it
will be anchored automatically into the application window.
*/
property Item statusBar
// The below documentation was supposed to be written as a grouped property, but qdoc would
// not render it correctly due to a bug (QTBUG-34206)
/*!
\qmlproperty ContentItem ApplicationWindow::contentItem
This group holds the size constraints of the content item. This is the area between the
\l ToolBar and the \l StatusBar.
The \l ApplicationWindow will use this as input when calculating the effective size
constraints of the actual window.
It holds these 6 properties for describing the minimum, implicit and maximum sizes:
\table
\header \li Grouped property \li Description
\row \li contentItem.minimumWidth \li The minimum width of the content item.
\row \li contentItem.minimumHeight \li The minimum height of the content item.
\row \li contentItem.implicitWidth \li The implicit width of the content item.
\row \li contentItem.implicitHeight \li The implicit height of the content item.
\row \li contentItem.maximumWidth \li The maximum width of the content item.
\row \li contentItem.maximumHeight \li The maximum height of the content item.
\endtable

There is a similar macro QWINDOWSIZE_MAX in qwindow_p.h that is used to limit the
range of QWindow::maximum{Width,Height}
However, in case we have a very big number (> 2^31) conversion will fail, and it will be
converted to 0, resulting in that we will call setMaximumWidth(0)....
We therefore need to enforce the limit at a level where we are still operating on
floating point values.
