Bug in SetWindowPointer(... WA_Pointertype)

Postby blmara » Fri Sep 11, 2015 11:10 pm

Hi!

After changing my application's window pointer code to use the new SDK's default pointers i.e. IIntuition->SetWindowPointer(win,WA_PointerType,...) I noticed that my application would hang with some pointer selections (like POINTERTYPE_SELECT). I confirmed the problem with this tag with this modified window.c example from SDK. Clicking the "Click me" gadget will change pointer until the POINTERTYPE_PEN, which hangs the system completely. Note: Code outputs the used pointertype with DebugPrintF, easily seen with Sashimi.

Code: Select all
/* Window pointer Example
gcc -o Window testWindow.c -lauto
quit
*/

/**

 **  Simple window.class example used to test newer features.
