OGLSetCtrlAttribute
int OGLSetCtrlAttribute (int panelHandle, int OGLControlId, int controlAttribute, ...);
Purpose
Sets an OGL control attribute for the selected OGL control on the selected panel.
Since attributes may return values of different data types with different valid ranges, a list of attributes, their data types, and their valid values are provided in the help for attributeValue.
The user cannot set some attributes. These attributes are denoted in the help for attributeValue. Use the OGLGetCtrlAttribute function to examine these attributes.
