[Completely solved] QGraphicsTextItem: Howto start editing via code?
How do I start text editing via code for those QTextDocument based classes?
Based on my experiments with QGraphicsTextEdit, the obvious attempt was to use setFocus. However, while I get the nice frame that indicates editing, and also a blinking cursor, I cannot type until I actually click into the widget using the mouse.
How to do it? Of course, I can simulate a mouse click, but that sounds ugly.
EDIT: I have since found that in a very simple test sample, setFocus works. So something in my environment seems to block me.
EDIT2: Apparently, a QPushButton is soaking up the key press events. How I just have to find out why it's doing that, although I clearly have set the focus elsewhere.
EDIT3: Setting the focus on a QGraphicsItem does not automatically cause it to receive keyboard events, because one of the QGraphicsViews showing this item must receive the keyboard focus, too.
have you tried this:
@QWidget *w = QApplication::focusWidget();
// set your focus
bq. Returns the application widget that has the keyboard input focus, or 0 if no widget in this application has the focus.
No, I haven't. But it now appears logical to me that a QGraphicsItem cannot know which of the views displaying it should receive the focus. Therefore, setFocus on a QGraphicsItem alone does not contain enough information to determine the focusWidget.
