Mouse button not working in screens in OS X

[jjsonick]

On Mac for me, PureBasic recognizes mouse clicks as expected with Windows/Gadgets, but it seems to ignore mouse clicks when using a Screen instead. I have read that there's issues with right-click sometimes on Mac, but this is left-click, too.

For instance, I run the included Gadget.pb example (Window based gadgets) and clicks work fine, but when I run Mouse.pb (Screen based), the logo graphic moves with the mouse as expected, but it is impossible to exit the running program, as left-clicks are ignored. I had to add "KeyboardPushed(#PB_Key_Escape)" as the Until condition to get the example not be be stuck in its Repeat loop.

I'm on a MacBookPro, OS X 10.7.5, using v5.10 Revision: 1472 64-bit version (the demo). I tried with both trackpad and a usb Logitech mouse - same results. With a Screen, mouse movement registers, clicks do not.

I altered the Mouse.pb to be a bit shorter to demonstrate this. Position of logo should change when left-click, but does not. Can others take a look at this and the original Mouse.pb to confirm? Thanks!

I confirm this behavior (Mountain Lion, PB 5.10x86). The mouse-button does not fire.

After changing

Code: Select all

LoadSprite(0, "Data/PureBasic.bmp", 0)

to

Code: Select all

LoadSprite(0, #PB_Compiler_Home + "Examples/Sources/Data/PureBasic.bmp", 0)

the code example posted by jjsonick can be executed without errors. And furthermore I can confirm that the detection of a left mouse click does not work in MacOS X 10.6.8 (Snow Leopard) with the Cocoa framework (default) in PB 5.11 x86. But if setting the subsystem in "Compiler/Compiler Options..." to "Carbon" the detection of the left mouse button works like a charme...

the code example posted by jjsonick can be executed without errors.

Ah, sorry about that - I had saved this altered version of mouse.pb in the Examples/Sources directory, so it worked as is there.

Thanks for testing and confirming, Shardik and jamirokwai!

Can this thread be moved to the Bugs-Mac OSX forum? Or should I just make a new post there?

For OS X 10.6+ with PB 5.10+ you can use this as a workaround

Code: Select all

If CocoaMessage(0, 0, "NSEvent pressedMouseButtons") = 1; check for left mouse button
  MouseLocate(400, 300)
EndIf
