Detect Window Maximize event

I want to use the maximize button as a shortcut to set my game to fullscreen mode.

I've enabled the button on the window - but I can't figure out how to detect when the user has clicked on it. Currently when I click on it, the window maximizes with my game still running in the top corner in an 800x600 rectangle.

(Don't want to use MaxGUI, either).

You can use MaxGUI (source) to find out how it detects it.

I don't have MaxGUI on this PC and TortoiseSVN says it can't connect to the repository to download it. Sod's law....

Just had a look at the MaxGUI source on my other PC - might as well be written in chinese.

Any advice?

I thought I could work around this by waiting for a EVENT_WINDOWSIZE event. It never gets returned.

EVENT_MOUSEMOVE works.

EVENT_WINDOWCLOSE also doesn't work. Clicking the close button seems to return a value of 259, which is not EVENT_WINDOWCLOSE.

I think there's something proplerly wrong here...

It couldn't be answered here although it gives a way to get the current status rather than have an event triggered when the button is pushed.

Sorted it using isZoomed. Like you said, it checks the status rather than detecting the event itself.

Extern "win32"
        Function IsZoomed%(hWnd%) = "IsZoomed@4"
        Function GetActiveWindow%()
End Extern

Then...

	Function update:Object( id,Data:Object,context:Object )
		PollEvent()
		Select CurrentEvent.id
		Case EVENT_MOUSELEAVE,EVENT_APPSUSPEND
			gamestats.display.mouseInWindow = False
		Case EVENT_MOUSEENTER,EVENT_APPRESUME
			gameStats.display.mouseInWindow = True
		End Select
		
		'check for maximised window
		If isZoomed(getActiveWindow())
			If gameStats.display.depth = 0
				gameStats.display.depth = 32
				gameStats.display.fullScreen = True
				gui.changeGraphicsMode()
				scaling = New tScaling
			EndIf
		EndIf
	End Function

Obviously this won't run 'as is' cos its out of my game (this function is added as a flip hook), but you get the idea.


Interested if anybody has a better way...

WxWidgets, it's the real stuff compared to the street crack of maxgui.

That's not an option.

I don't want to include a massive module just for this. I'm not using MaxGUI either, by the way.

Ah sorry, my bad.

a tad overkill, wxWidgets, I'd agree :-p
