Mac Retian and OpenGL

Hi,
    I'm using wxGLCanvas to render OpenGL on a Retina display of a Mac. 
During rendering, I have to use glViewport(0, 0, GetContentScaleFactor() * 
width, GetContentScaleFactor() * height) to achieve full-screen rendering, 
instead of rendering only in the bottom-left quarter of the area.
    However, when I want to use pick to select a certain rendering unit, 
wxGetMousePosition() returns physical coordinates. If I multiply all 
physical coordinates by GetContentScaleFactor(), the coordinates are 
incorrect again in some PopupMenu() scenarios. Is there a relatively simple 
way in wxWidgets to handle all of this? 
    My Mac version is 26.2, and the wxWidgets version is 3.2.9.
    Thank you very much!

Best Regards
Shi
