Release 10.1A: OpenEdge Development:
Programming Interfaces

> ## Allowing the user to change colors and fonts

> In graphical interfaces, Progress allows you to invoke native common dialogs for color and font selection in the 4GL using the `SYSTEM–DIALOG COLOR` and the `SYSTEM–DIALOG FONT` statements. Using these dialogs, you can allow the user to choose a new value for a color or font number. Once the user chooses a value, Progress stores the choice in the color or font table location specified by the number. All visible widgets defined with the specified color or font number immediately redisplay according to the user selection.
