Constructor & Destructor Documentation

QtColorPicker()

QtColorPicker::QtColorPicker	(	QWidget *	parent = 0,
		int	cols = -1,
		bool	enableColorDialog = true
	)

Constructs a QtColorPicker widget. The popup will display a grid with cols columns, or if cols is -1, the number of columns will be calculated automatically.

If enableColorDialog is true, the popup will also have a "More" button (signified by an ellipsis "...") that presents a QColorDialog when clicked.

After constructing a QtColorPicker, call insertColor() to add individual colors to the popup grid, or call setStandardColors() to add all the standard colors in one go.

The parent argument is passed to QFrame's constructor.

This signal is emitted when the QtColorPicker's color is changed.
\a color is the new color.

To obtain the color's name, use text().

GetColor()

QColor QtColorPicker::GetColor ( const QPoint &  point, bool  allowCustomColors = true  )

static

 Pops up a color grid with Qt default colors at \a point, using
 global coordinates. If \a allowCustomColors is true, there will
 also be a button on the popup that invokes QColorDialog.

 For example:

 \code
         void Drawer::mouseReleaseEvent(QMouseEvent *e)
         {
         if (e->button() & RightButton) {
                         QColor color =

QtColorPicker::GetColor(mapToGlobal(e->pos())); } }

insertColor()

void QtColorPicker::insertColor	(	const QColor &	color,
		const QString &	text = QString(),
		int	index = -1
	)

Adds the color color with the name text to the color grid, at position index. If index is -1, the color is assigned automatically assigned a position, starting from left to right, top to bottom.

setCurrentColor

void QtColorPicker::setCurrentColor ( const QColor &  color )

slot

Makes color current. If color is not already in the color grid, it is inserted with the text "Custom".

This function emits the colorChanged() signal if the new color is valid, and different from the old one.

Adds the 17 predefined colors from the Qt namespace.

(The names given to the colors, "Black", "White", "Red", etc., are all translatable.)

Property Documentation

colorDialog

QtColorPicker::colorDialog

read

Whether the ellipsis "..." (more) button is available.

If this property is set to TRUE, the color grid popup will include a "More" button (signified by an ellipsis, "...") which pops up a QColorDialog when clicked. The user will then be able to select any custom color they like.
