\inherits Loader
\since QtQuick.VirtualKeyboard 1.1
\brief Allows dynamic loading of keyboard layout.
This type is useful for keyboard layouts consisting of multiple pages of keys.
A single keyboard layout (a page) is defined by using the Component
as a container. The active keyboard layout can then be changed by
setting the sourceComponent property to a different value.
Example:
\code
import QtQuick 2.0
import QtQuick.Layouts 1.0
import QtQuick.VirtualKeyboard 2.1
// file: layouts/en_GB/symbols.qml
KeyboardLayoutLoader {
property bool secondPage
onVisibleChanged: if (!visible) secondPage = false
sourceComponent: secondPage ? page2 : page1
Component {
id: page1
KeyboardLayout {
// Keyboard layout definition for page 1
}
}
Component {
id: page2
KeyboardLayout {
// Keyboard layout definition for page 2
}
}
}
\endcode
*/

/*! Sets the input method for all the keyboard layouts loaded

layout, or commonly at this context. If set separately, then this
property should not be modified.
*/
property var inputMethod: item ? item.inputMethod : null
/*! This function may be overridden by the keyboard layout
to create the input method object dynamically. The default
implementation forwards the call to the child keyboard
layout.
The input method object created by this function can outlive
keyboard layout transitions in certain cases. In particular,
this applies to the transitions between the layouts listed in
the sharedLayouts property.
*/
function createInputMethod() {
return item ? item.createInputMethod() : null
}
/*! List of layout names which share the input method created
by the createInputMethod() function.
If the list is empty (the default) the input method is not
shared with any other layout and will be destroyed when the
layout changes.
The list should contain only the name of the layout type,
e.g., ['symbols']. The current layout does not have to be
included in the list.
