Track Changes

Post by anasrallah » Wed Mar 27, 2013 2:25 am

what is the best way to determine if the document got changed and needs saving? I can have a boolean variable for my functions but I'm not able to track when right click is used.

Hi,

This is definitely an app level design. An imaging SDK should not keep track of this, but you should in your application. Different people do it in different ways, whether a resource manager, a history stack, or just simple flags, its up to you.

Best of luck,
Sami

How do you track rotation events done with right click on gdviewer?
Thanks

Hi,

Here is a list of all the events of the GdViewer, among them is the RotationChanged event:
