Detect Minimise on Mac - I've added a minimise btn

OK I figured out how to add a minimise button to graphics windows created on Mac OSX with Graphics w,h,0.

A minimise button cannot be added once the window is created (according to the Mac Developer docs) only as the window is created. So I had to modify glgraphics.macos.m by finding this line (990):

style=NSTitledWindowMask|NSClosableWindowMask

and changing it to:

style=NSTitledWindowMask|NSClosableWindowMask|NSMiniaturizableWindowMask;

Then rebuild modules.

This works and when you click minimise it does minimise, woo! However it not passing a suspended event into BMax so I can't stop the music and can't stop game logic which is naff.

However, I've no idea where to go from here. I.e. how to detect the minimise. Probably another module needs to be modified so that an AppSuspend event is fired off when the game is minimised. Can anyone help with this as it would be great to get it sorted for the Mac! Thanks in advance.

Look into the windowDidMiniaturize and windowDidDeminiaturize delegates.

Adding them to the BBGLWindow object and firing the aproproate events may work.

And check out the isMiniaturized, miniaturize and deminiaturize methods as well.

souunds good. Anyone with good Objective C skills able to assist? thx

Add these after windowShouldClose on line 39 and see what happens ;)

-(void) windowDidMiniaturize:(NSNotification *) note {
	bbSystemEmitEvent( BBEVENT_APPSUSPEND,&bbNullObject,0,0,0,0,&bbNullObject );
}
-(void) windowDidDeminiaturize:(NSNotification *) note {
	bbSystemEmitEvent( BBEVENT_APPRESUME,&bbNullObject,0,0,0,0,&bbNullObject );
}

Awesome, thanks, will try in about an hour!

Excellent it works thanks! Really appreciated. Shame it's a module tweak though, it would be great if BRL made this standard (or at least made the minimise icon optional.

Interestingly, because my game uses HideMouse so it can draw it's own mouse cursor, when the window is minimised, the Mac mouse cursor still disapears when it moves over where the window was, how freaky is that? I fixed that with some code that called ShowMouse when suspended was detected and HideMouse when it resumes.

OK someting else related, if I press F11 to hide all windows to show the desktop, the game continues to run and also if you move the mouse where the window was, all the buttons make mouse over noises (although they can't be clicked as focus goes to the desktop). Do you know how to detect the F11 event as I'd like to treat it like a normal suspend/resume via app lost focus or app was minimised. Thanks!

Grey- I've been watching your Framework evolve for quite some time and I am pleased to see progress being made on cross-platform functionality. I'll be buying 1.05 for sure.

This seems to be a common problem with cocoa (from what i could find with my limited searching anyway).
Does this happen without the minimize tweak as well?
And does it only happen when showing the desktop, and not when doing expose?

There are ways to not include the window in any expose action though, but thats probably not what you want.

Tachyon: Cool! Yeah the framework has compiled on the Mac for a long time but it's only recently that I've been looking into all the little OS-related quirks and getting them fixed (which I did for Windows last year). They are very nearly all done. I'm finding the Mac ones hard to solve though because I can deal with Windows API but the Mac stuff is very new to me. So I rely on the help of Mac experts like Grable, Brucey and others.

Grable: I can take the tweak out and see. I had never tried to press F11 when one of my games was running before. Ok just confirmed that it happens without the tweak.

What is expose? Basically the problem is with F11, is there something else I should test?

Yeah I just need to receive a system message that F11 was pressed OR detect that the system is in the F11 state (whatever it's called) so I can take my own action.

Any ideas?

Exposè (got the right letter this time ;) is all the fancy effects like F11 and the "show all windows" thingy.


you can remap them to any key or mouse button though, so calling it F11 can be a bit misleading. and whatever button it is assigned to is trapped by the os, so im not sure you can check for it.

I cant find any info on detecting expose actions, im not even sure its possible.
It seems the windows arent moved at all, only the graphic of them.

You could try the various mailing lists, google isnt much help today.

Hmm OK thx. This may just have to be a "feature", much as I'd hate to leave it at that.
