Key Events not handled by QQuickView before mouse-click [SOLVED]

frankiefrank

I have an issue with key events in some basic QML, when loaded in a widget application,.

The key events are not handled after the window is loaded. I have to actually click on the QML scene once and only after that the key events work.

I suspect this is a Qt Bug but maybe anyone can tell me how I can really make the key events work immediately?

Here's my QML code: (please forgive the formatting, with the new forums I can't manage to make simple code tags work for some reason)

   // FocusTest.qml
   import QtQuick 2.4

   Rectangle {
id: mainContainer	
width: 700
height: 700

 // Some optional debug messages to see if/when focus or activeFocus is changed
 // onActiveFocusChanged: console.log("active focus of mainContainer changed: " + activeFocus)
 //	 onFocusChanged: console.log("focus of mainContainer changed to " + focus)

   // This should be enough to make the main container in focus
focus: true
Keys.onPressed: {
	txt.text = event.key
	console.log("Keys.onPressed: " + event.key);
}

Text {
	id: txt
	width: 300
	height: 300
	anchors.centerIn: parent
	text: "expect key events here..."
}
}

Now I made a simple Qt Widgets Application, and to the default MainWindow class I added a QQuickView member.

In MainWindow.cpp constructor:

ui->setupUi(this);

quickView = new QQuickView();
QWidget *containerWidget = QWidget::createWindowContainer(quickView);
setCentralWidget(containerWidget);
quickView->setSource(QUrl::fromLocalFile("D:\\FocusSample.qml"));

I tried setting focus to true with a timer, I tried calling forceActiveFocus(), but both didn't work for me. The key events only get handled after the first mouse click.

Is there anything I can do to force the focus? Is there a way to simulate that first click, or another way to force focus?

Also - the same QML works as expected when not loaded as a widget (i.e. if I create a .qmlproject to contain the QML only and run that with Qt Creator).

@frankiefrank Is it the same behavior with QQuickWidget ?

Great tip! No, using QQuickWidget seems to solve the problem!
