Detailed Description

KXYSelector is the base class for other widgets which provides the ability to choose from a two-dimensional range of values. The currently chosen value is indicated by a cross. An example is the KHSSelector which allows to choose from a range of colors, and which is used in KColorDialog.

A custom drawing routine for the widget surface has to be provided by the subclass.

Constructs a two-dimensional selector widget which has a value range of [0..100] in both directions.

Destructs the widget.

Sets the current values in horizontal and vertical direction.

Sets the range of possible values.

Returns: the current value in horizontal direction.

Returns: the current value in vertical direction.

[const]

Returns: the rectangle on which subclasses should draw.

[signal]

This signal is emitted whenever the user chooses a value, e. g. by clicking with the mouse on the widget.

[protected: virtual]

Override this function to draw the contents of the widget. The default implementation doesn nothing.

Draw within contentsRect() only.

[protected: virtual]

Override this function to draw the cursor which indicates the currently selected value pair.
