Detailed Description
A color selection dialog.
Features:
- Color selection from a wide range of palettes.
- Color selection from a palette of H vs S and V selectors.
- Direct input of HSV or RGB values.
- Saving of custom colors
In most cases, you will want to use the static method KColorDialog::getColor(). This pops up the dialog (with an initial selection provided by you), lets the user choose a color, and returns.
Example:
QColor myColor; int result = KColorDialog::getColor( myColor ); if ( result == KColorDialog::Accepted ) ...

KDE Color Dialog
The color dialog is really a collection of several widgets which can you can also use separately: the quadratic plane in the top left of the dialog is a KXYSelector. Right next to it is a KHSSelector for choosing hue/saturation.
On the right side of the dialog you see a KPaletteTable showing up to 40 colors with a combo box which offers several predefined palettes or a palette configured by the user. The small field showing the currently selected color is a KColorPatch.
