Colors Used by PM Controls

PM controls make extensive use of presentation parameters for determining the fonts and colors to paint with. All the controls that display text strings use the font set by the PP_FONTNAMESIZE presentation parameter. The colors used in the controls can be set using presentation parameters. Each control responds to a subset of the color presentation parameters, depending on the type of painting it is required to do. Some of the color presentation parameters are specific to a single control; others are used by many or all of the controls.

When there are no presentation parameters set, a control selects the default colors to use. If nothing else is available, the control will use the default system colors (obtained by calling WinQuerySysColor). When no system color is available, it will use a hard-coded RGB color.

In summary, the colors a control window uses depends on what has been set by the application and the user. The order of precedence (from first to last) for a PM control's choice of colors is as follows:

• Presentation parameters
  
• Application-specific control colors
  
• Global control colors
  
• Default colors (system colors, where available)
