Bug: no way to poll Alt+F4 event using sf::Style::None

[Robert42]

Hi,

Alt+F4 behaves different, depending on the window-style:

• sf::Style::Default You get a Close Event. fine.
• sf::Style::Fullscreen You get a KeyPressed event. fine.
• sf::Style::None You get neither a Close, nor a KeyPressed Event.

Tested using SFML 2.0 fetched and built today.

If you agree that's a bug, I can create a pull-request if you want

greetings, Robert

Edit: I am using LinuxMint 13 x64

Is it really fine that you get different types of events in fullscreen and windowed mode? I wouldn't expect that.

I do

Wow Xlib is uglier and it's documentation harder to find than I expected. (Actually I couldn't find any X11 Documentation regarding MOTIF_WM_HINTS)

The only working thing I could figure out is to get Alt+F4 beeing triggered a Close event. I couldn't find a way to get an Alt+F4 keyevent triggered in window mode.

My workaround was to use

            if (style & Style::Close)
            {
                hints.Decorations |= 0;
                hints.Functions   |= MWM_FUNC_CLOSE;
            }
            if (style==0)
            {
                hints.Decorations |= 0;
                hints.Functions   |= MWM_FUNC_CLOSE;
            }
 

instead of

            if (style & Style::Close)
            {
                hints.Decorations |= 0;
                hints.Functions   |= MWM_FUNC_CLOSE;
            }
 

Which is far to hacky for a pull request.

Sorry that I couldn't contribute more

Don't worry, XLib is such an undocumented mess to work with... I plan to replace it with XCB soon.

You can open an issue on the tracker, so that this bug doesn't get lost in the forum
