Detailed Description

A cross platform button subclass for selecting colors. Will open a color chooser dialog when clicked. Offers live updates to button from color chooser dialog.

A cross platform button subclass for selecting colors.

A subclass of QPushButton is needed to draw the button content because some platforms such as Mac OS X and Windows XP enforce a consistent GUI look by always using the button color of the current style and not allowing button backgrounds to be changed on a button by button basis. Therefore, a wholely stylesheet-based button is used for the no-text variant.

This class is a simplified version of QtColorButton, an internal class used by Qt Designer to do the same thing.

Will open a color chooser dialog when clicked. Offers live updates to button from color chooser dialog

Note
inherited base class moved from QToolButton to QPushButton in QGIS 1.9

void QgsColorButton::setButtonBackground ( QColor  color = QColor())
slot

Sets the background pixmap for the button based upon color and transparency.
