For example, you might use this in a drawing program to allow the user to set the brush color. The static functions provide modal color dialogs. \omit If you require a modeless dialog, use the QColorDialog constructor. \endomit The static getColor() function shows the dialog, and allows the user to specify a color. The getRgba() function does the same, but also allows the user to specify a color with an alpha channel (transparency) value. The user can store customCount() different custom colors. The custom colors are shared by all color dialogs, and remembered during the execution of the program. Use setCustomColor() to set the custom colors, and use customColor() to get them. Additional widgets that allow users to pick colors are available as \l{Qt Solutions}. The \l{dialogs/standarddialogs}{Standard Dialogs} example shows how to use QColorDialog as well as other built-in Qt dialogs. \image plastique-colordialog.png A color dialog in the Plastique widget style. \sa QColor, QFileDialog, QPrintDialog, QFontDialog, {Standard Dialogs Example} */ /*!
