Exiting a ProMousePick() loop to exit a dialog

[BobMonat]

I have inherited a application which creates a ProUIDialog. One of the pushbuttons activates a loop to allow the user to select items from a 3D display list.

The code for the mouse pick is:

while(1) {

	status = ProMousePickGet (PRO_ANY_BUTTON, &button, screen_pt);
	if ( button == PRO_MIDDLE_BUTTON || status != PRO_TK_NO_ERROR ) break; ... }

Picking the middle mouse button exits the loop and makes the dialog active again. Is there any way to set the dialog cancel button (red X) to be enabled? I set ProUIDialogCloseActionSet() but when in the loop, picking the cancel button just rings a bell.

Any ideas?

Thanks,

Bob

Hi all,

Bob,

Without knowing how the loop is constructed it is a shot in a dark...

I would either insert a dialog close statement in a button check block:

if( button == PRO_MIDDLE_BUTTON ... ) {

     ProUIDIalogUnload(); // check spelling

     break;

}

or use a static module level variable which would be set depending on button pressed and an observer within a dialog code to react on a variable value.

HIH.

Feliks.
