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

Definition at line 31 of file qgscolorbutton.h.

Constructor & Destructor Documentation

QgsColorButton::QgsColorButton	(	QWidget *	parent = `nullptr`,
		const QString &	cdt = `""`,
		const QColorDialog::ColorDialogOptions &	cdo = `nullptr`
	)

Construct a new color button.

Parameters

parent	The parent QWidget for the dialog
cdt	The title to show in the color chooser dialog
cdo	Options for the color chooser dialog

Note: changed in 1.9

Member Function Documentation

bool QgsColorButton::acceptLiveUpdates ( )

inline

Whether the button accepts live updates from QColorDialog.

Definition at line 96 of file qgscolorbutton.h.

void QgsColorButton::changeEvent ( QEvent * e )

overrideprotectedvirtual

Reimplemented from QAbstractButton.

Definition at line 396 of file qgscolorbutton.cpp.

QColor QgsColorButton::color ( ) const
