Detailed Description

KDualColorButton allows the user to select two cascaded colors (usually a foreground and background color). Other features include drag and drop from other KDE color widgets, a reset to black and white control, and a swap colors control.

When the user clicks on the the foreground or background rectangle the rectangle is first sunken and the currentChanged() signal is emitted. Further clicks will present a color dialog and emit either the fgChanged() or bgChanged() if a new color is selected.

Note: With drag and drop when dropping a color the current selected color will be set, while when dragging a color it will use whatever color rectangle the mouse was pressed inside.

Constructs a new KDualColorButton with the supplied foreground and background colors.

Reimplemented from QWidget

void  slotSetForeground (const QColor &c)

[slot]

Sets the background color.

void  slotSetCurrent (KDualColorButton::DualColor s)

[slot]

Sets the current selected color item.

void  slotSetCurrentColor (const QColor &c)

[slot]

Sets the color of the selected item.

void  fgChanged (const QColor &c)

[signal]

Emitted when the foreground color is changed.

void  bgChanged (const QColor &c)

[signal]

Emitted when the background color is changed.

void  currentChanged (KDualColorButton::DualColor s)

[signal]

Emitted when the user changes the current color selection.

void  metrics (QRect &fgRect, QRect &bgRect)

[protected virtual]

Sets the supplied rectangles to the proper size and position for the current widget size. You can reimplement this to change the layout of the widget. Restrictions are that the swap control will always be at the top right, the reset control will always be at the bottom left, and you must leave at least a 14x14 space in those corners.
