wxGLCanvas and wxAuiNotebook

[luca]

Hello,

when draggin tabs around in a wxAuiNotebook there is a very usefull semi transparent background window that shows where the tab will go if you release the left mouse button. But i am using some wxGLCanvas as pages in the notebook, which get redrawn like 30 times a second, and this causes either flickering and the semi-transparent background window is overdrawn. Since i want to display clearly where the dragged page is going to, I could:
1- detect when dragging is ON, and in that case i should stop redrawing wxGLCanvas'es.
2- intercept the dragging events, retrieving the coordinates of the transparent window, and draw the sub-rectangles in my on wxGLCanvas myself.

I tryed to intercept wxEVT_COMMAND_AUINOTEBOOK_DRAG_MOTION, but it is always handled withing the wxAuiNotebook class, and the parents do not gets the notification.

Any hint?

Thanks in advance,
Luca

Hi,

You need to access the m_action member of wxAuiManager. This constant tells you what the mouse is doing. The value is one of the mouse action enums. Since it's protected, you need to drive a small class from wxAuiManager that allows access to that member, something like GetMouseAction().

Best of luck,
Ben
