OpenGL rendering works a lot better on a panel set to have no background brush, using SetClassLong(hwnd,GCL_HBRBACKGROUND,0). However, this makes all your panels so that they don't get refreshed when another window is dragged over them. The way around this is to set one panel with SetClassLong(hwnd,GCL_HBRBACKGROUND,0), which will remove the background for all panels. Then you use SetPanelColor() on all your non-rendering panels. You will also need to cover each window you create with a large panel: window=CreateWindow("",0,0,400,300) windowpanel=CreatePanel(0,0,ClientWidth(window),ClientHeight(window),window) SetGadgetLayout windowpanel,1,1,1,1 SetPanelColor windowpanel,r,g,b This will give you OpenGL viewports that don't get cleared, as well as regular solid application panels. |
