Modal dialogs and pen up messages

[hbarta2]

Posted on April 13, 2015 at 23:39

I have a popup dialog that I load for some text entry. If I make it modal, the dialog procedure no longer gets 'pen up' events. If it is not modal, the user can interact with other things on the screen behind the dialog.

This dialog (built with the GUI builder) is meant to support data entry and with no pen up events, the last touched button remains active until a different button is pressed. Not only does this look crappy but it becomes impossible to enter double letter combinations. Below is the entire code for this example which consists of the beginnings of a QWERTY keyboard. (QWER only supported for now. 😉 ) Is there a way to get full functionality for a Modal dialogue? Other suggestions for resolving this welcome! (Should I send my ownWM_NOTIFICATION_RELEASED events?) Thanks!
