I have written a small set of user ortho 2d interface classes one of which includes a slider bar control.
I detect the intersection with the slider's geometry to check the mouse has a hold of it and then update it's position based on the coordinates I get from the event handlers 'drag' event. The problem is that when I update the positionattitudetransform of the slider geometry with the coordinates of the mouse from the event handler i get a crash. I have a feeling that it is because I am trying to update the position in Drag event during the event traversal. Is it it correct to assume that you should only update transformations, geometry etc when in the update traversal? If so how can I ensure that these changes are made in the update traversal and not in the event loop? My apologies for this rather vague description, hopefully someone will see what I'm getting at. Cheers, Kim.
