Return Code | Significance |
0 | action was registered |
1 | action was not registered |
After a bitmap area (a field title defined as graphics) has been clicked on, the function passed is called with the following parameters:
If the function is called several times with different function pointers, the functions passed this way form a stack that is executed at the trigger moment. If one of the functions in the stack delivers a return code which is not zero, the next trigger function of the stack is jumped to (no mouse action on bitmap registered). If the return code = 0, the execution of the function is stopped.
