MouseCallBack - how to get mouse up message ?

[tagopinath]

Hello,

I am trying to draw something on an object in viewport, for that, i am making a subclass of MouseCallBack and in the proc() i am using MOUSE_POINT, MOUSE_FREEMOVE and MOUSE_MOVE cases for drawing purpose.

The functionality which is added in MOUSE_POINT and MOUSE_FREEMOVE works fine, means, i click at any place on object, with mouse clicked, i drag and drawing happens on mouse position. But, when i release mouse, and move, drawing is still happening. I am trying to add a flag on mouse up, but i didn't know where to add. 

I am not modifying override function.

Also, when i change MOUSE_FREEMOVE to MOUSE_MOVE, then drawing not happens on mouse drag.

Please suggest any ideas.

Regards,

Gopi.

The only way I know how to extend the functionality of mouseTrack() is to do it yourself by writing your own TrackMouseCallBack using the MAX SDK. The SDK samples have a complete example: ...maxsdk/samples/maxscript/mxsagni/moustrak.cpp

As he wrote about proc(), I assume he is already talking about C++.  I would search for "MOUSE_LBUTTON" in the SDK samples.

Thank you Denis and Istan for your replies.

I am getting some idea after looking into MOUSE_LBUTTON option. Will try on that.
