QColorButton is a widget to show an initial color and choose a different color when it's double-clicked.

There's an api to set the initial color for QColorButton and retrieve its new color.

Copy QColorButton.h and QColorButton.cpp to your project.

Running the test program will initially show a window with an initial color. Red in the case of the test program.

Double click the red area to bring up the standard color dialog.

Selecting OK after choosing a different color will result in the red area changing to the color you chose.
