The Color Scheme setup dialog is comprised of three sections:
The color scheme Preview.
The current Widget Color.
The available Color Schemes.
(A "Widget" is a commonly-used programmer's term for referring to User Interface elements such as buttons, menus, and scroll bars )
This section of the dialog demonstrates how a color scheme applies to a sample selection of widgets. A color scheme consists of a set of ten colors. These colors apply to the :-
Inactive title bar background
Inactive title bar text
Active title bar background
Active title bar text
General background
General foreground
Selection background
Selection text
Window background
Window text
Labels on the sample widgets will help you identify where these colors apply.
The colors are grouped into 5 foreground / background pairs. Thus, good contrast between the foreground and background colors of widgets can be ensured at all times.
When you press Ok or Apply the color scheme you have selected will be written to the desktop configuration.
Note: Pressing Ok or Apply applies changes made in all of the display setup modules.
There are some problems in the Qt toolkit when changing the colors in a running application, particularly with lists and combo boxes. These elements will not be displayed properly until the applications are restarted. Hopefully these problems will be fixed in a future release of Qt.
