Qt5 native messages not propogated?

[ComServant]

I'm not sure. I'll just looked at the source of SFML, and this is what it looks like:

1. Qt creates the window
2. Qt gives me the HWND
3. I give SFML the HWND
4. SFML attaches it's own WndProc callback function to it, but saves the previous (Qt's) WndProc.
5. SFML receives the messages, processes them, then forwards them to the previous (Qt's) WndProc.

So it looks like SFML gets to process the Win32 events before Qt. I don't know why SFML is not processing the key presses (but is receiving mouse messages) then, but why it was previously with Qt 4.8.

It looks like I was investigating the wrong API - thanks for the help.

Greetings,

I've been on this case for awhile now and I still couldn't figure why SFML does not process mouse wheel and keyboard inputs anymore.

Could you tell us how you fixed it?

Note: It is clearly a QT modification from 4.8 to 5.x that brought this issue.

Thank you!

It's definitely a Qt issue, and I haven't gotten it working. I'm using Qt 5.0.1 - maybe someone has fixed it in a more recent update, but I can't check anytime soon.

I receive events for: Mouse movement and mouse button presses (include the middle button, which is the scroll wheel), but I don't receive events for mouse wheel movement or keypresses, even though the QWidget is clearly getting them.

I wonder if Qt treats mouse wheel in the same way as keypresses, and whether it is failing to call the Win32 DefWindowProc on them, or something.

Please provide a minimal compilable example demonstrating the problem.
