DESCRIPTION

SelectColor provides a simple way to select color. It can be displayed as a dialog box or as a menubutton.

WIDGET-SPECIFIC OPTIONS

-color: Specifies the initial color used in the widget's color selectors. When modifying a color that is used in the GUI, the value supplied is typically the existing value of that color.

-command: Specifies a command to be evaluated, with a color value appended, whenever the color selected in the dialog changes. This facility can be used to modify a color in the calling GUI and preview the change before deciding whether or not to accept it. If the user selects "Cancel" in the dialog, the command is called a final time to restore the initial color (supplied by option -color) that was used before the dialog was opened.

-help: This option takes a Boolean value. If the value is Boolean true, the SelectColor dialog will include a balloon help for text entry and mouse operation.

-parent: Parent of the Dialog. Dialog is centered in its parent. If empty, it is centered in root window.

-placement: Where to place the popup color dialog when displaying it. Must be any of: at, center, left, right, above, or below. If -parent is specified, placement will be in relation to the parent widget.

-type (read-only): Specifies the type of the SelectColor widget. Must be dialog or popup.
If type option is dialog, SelectColor::create directly creates the dialog, displays it and return an empty string if cancel button is pressed or if dialog is destroyed, and the selected color if ok button is pressed. In all cases, dialog is destroyed.
If type option is popup, SelectColor::create creates a small, popup dialog with a small set of predefined colors and a button to activate a full color dialog.
