Mac OS X: Mouse click don't always register when windowed

Reported by: SF/fds- Owned by: fingolfin
Priority: high Component: Port: Mac OS X
Version: Keywords:
Cc: Game:


The problem occurs with ScummVM 0.6.0pre (built on Feb 15 2004 12:54:39), "official" snapshot. I'm running Mac OS X 10.3.2 with an ATI Mobility 9000 (32 MB) card.

It seems some kind of bounding box doesn't always get reset correctly. The problem looks like this: whenever you move your mouse to a position outside this "bounding box," both the game's cursor and the default Mac OS X cursor is shown. If then you try to click with your mouse, nothing happens. As workaround #1 you can still press Enter on the keyboard which keeps on working even in this case.

Workaround #2: switch to full-screen (where things are normal) then switch back and the whole window is still nicely clickable.

The problem is triggered by non-300x200 games and/or magnification.

As I understand, 2x magnification is the default. ZAK FMTOWNS for example by default starts in a 640x502 window (borders and title bar included) and while the upper three inventory slots are clickable, rows four and five are already outside of this certain bounding box and are not, unless you use one of the two workarounds I described above. (You can also lower the magnification with Ctrl-Alt-minus and the whole of the tiny window will be clickable.)

This problem doesn't by default happen with 320x200 games such as Indy4 PC, DOTT PC or SamNMax PC, but can still be triggered by pressing Ctrl-Alt-= and thus switching to 3x magnification.

This is a recent problem as earlier snapshots (certain copies of 0.5.7cvs) behaved rather differently. It was quite challenging to move the mouse cursor outside and back inside the ScummVM window but when you finally managed to get the mouse cursor correctly visible and working in the window you wanted, the problem I described above didn't happen. I very much prefer the current behavior which lets you seamlessly move the mouse cursor in and out of ScummVM windows on Mac OS X.

I'm very sorry I didn't notice this at first:

My bug seems to be a duplicate of [ 896976 ] ZAK256: Inventory scroll arrow does not function(osx 0.5.7) func=detail&aid=896976&group_id=37116&atid=418820

Still, my description is hopefully more accurate and to the point.

"I very much prefer the current behavior which lets you seamlessly move the mouse cursor in and out of ScummVM windows on Mac OS X."

-> this is not related to ScummVM at all, this is due to a newer SDL (beta) version being used.

Anyway, I finally can reproduce the problem. The trick is to do this: 1) Make sure aspect correction is *disabled* in your config file 2) Start the launcher 3) From here start a non-320x200 game (e.g. zak256, sword1, ...) 4) Now you can observe the bug

So this is probably due to init_size being called again causing a bug...

We don't even receive the click events... either this is a bug in SDL, or we are misusing SDL somehow...

For what its worth there is a new snapshot built against an updated version of SDL from CVS. I'm not sure if this changes anything but I couldn't reproduce it here.

comment:6 by SF/fds-, 20 years ago

I have tried the new snapshot (Feb 17 2004 00:54:25) -- wow, fresh from the future. :) The problem is still there.

Also, turning on Aspect ratio correction doesn't seem to make a difference regarding this problem on my PowerBook (1280x854 desktop resolution).

I can confirm however that starting the game directly without using the launcher part is a functioning workaround. eg. /Applications/Games/scummvm/ scummvm zakTowns

As fingolfin discovered, the problem only occurs if you start the game through ScummVM's built-in launcher.

comment:7 by fingolfin, 20 years ago

Please read again what I wrote - I never said that turning on aspect correction would fix the problem. In fact for games which are not 320x200, you *can't* turn on aspect correction.

However, if you have aspect correction already on when you start ScummVM (by setting it in the config file), you can't trigger the problem.

Anyway I found the cause in the SDL sources and am looking into a fix.

The bug is now fixed in SDL CVS, and should be in SDL 1.2.7 (once that gets released).

Closing this as a duplicate of bug #896976
