Perhaps you’ve enabled the titlebar and control menu of a DataWindow control. You may even want the users to be able to minimize/maximize and reposition the control at runtime.
Now you’d like to trap when the user interacts with the control in this fashion in order to execute some logic when they do. Perhaps you’d like to know when/if the user closes the DataWindow control.
Go ahead and map a custom event for the DataWindow control to the pbm_syscommand Event ID.
For purposes of demonstration, I’ve placed a singlelineedit control on a window and assigned the commandtype argument value of the event (an unsignedlong) as a string to the text property of the sle.
sle_commandtype.text = String ( commandtype )
In the screenshot, you can see that I’ve trapped the user clicking on the titlebar of the DataWindow control with a commandtype value of 61458.
For your reference, I’ve included a roster of commandtype values here in this tip. Happy trapping!
