[Qt-interest] When using Qt, pressing an item on the toolbar control causes the main application window to lose focus.

[Malyushytsky, Alex]

>>Please note: The Visual C++ SDK behaves normally.

"The Visual C++ SDK" example design is different from other examples -  No dialogs are opened and NO other widgets get focus.
Design other examples the same way and you will have similar results.

Subject: [Qt-interest] When using Qt, pressing an item on the toolbar control causes the main application window to lose focus.

I realize the Qt community can not easily assist me. I have submitted a support request to ESRI and the Trolls. What I was wondering is has anyone programmed an application where they were using a QWidget to load an ActiveX control and when they pressed on the QWidget that had loaded the ActiveX control the main application window (a QMainWindow) lost focus. Programmatically, is there a way to return focus to the main window? Thanks in advance.

Focus Problems with ArcObjects Cross-Platform C++ SDK

Target Environment Development OS: 64-bit Windows 7 Deployed OS: 32-bit Windows XP Toolkit: Qt 4.7.1

In the next three videos, please note the issue. At start-up, a user can hover across the toolbar and it brings up the tool tip for each command/tool. When a user presses a command/tool the main application window loses focus. If the user hovers across the toolbar now, there are no tooltips- obviously. If the user subsequently clicks commands, then they appear raised and tooltips still do not work while the main application window does not have focus. Tools function properly other than no tooltips.

If the video is too small, then please run it full-screen.

Please note: The Visual C++ SDK behaves normally. The main window does not lose focus. The delay when I click Fixed Zoom-In is from labeling. http://www.youtube.com/watch?v=dg4UjE77R-I&feature=player_embedded

My question is, for the Qt example, how do I get the focus to return to the main window after clicking an item on the toolbar? I suppose I could use the IToolbarControlEvents interface to capture one of the mouse actions, but how would I return the focus to the main window? Would I pass the QMainWindow into the IToolbarControlEvents implementation constructor or access it through the QAxCtl through the IToolbarControl interface(how?) and then accessing the QMainWindow through QAxCtl through accessing parent widgets (provided they had been set) until I reached the top level?

Thanks in advance.

If you have ArcObjects Cross Platform C++ or/and Visual C++ (.NET) SDK(s) installed, the example are:
