COLORDROPDOWN Control

The COLORDROPDOWN control is a customized Dropdown-list COMBOBOX control that allows a user to select a color.

Developer Notes

1. The Presentation Server supports two "special" color values that are not actual RGB values. These are:

• -1 (TRANSPARENT)

• -2 (USEDEFAULT)

However, these values also conflict with the special color codes (-1 to -5) that are used with the image COLORKEY property (these denote which pixel to use as the "transparent color" when rendering an image). In order for these to be displayed correctly in the COLORDROPDOWN control its COLORKEYMODE property must be set accordingly.
