Detailed Description
KSelector is the base class for other widgets which provides the ability to choose from a one-dimensional range of values.An example is the KGradientSelector which allows to choose from a range of colors.
A custom drawing routine for the widget surface has to be provided by the subclass.

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

Override this function to draw the contents of the control. The default implementation does nothing. Draw only within contentsRect(). Reimplemented in KValueSelector, and KGradientSelector. Definition at line 309 of file kselect.cpp. |
|
Override this function to draw the cursor which indicates the current value. This function is always called twice, once with argument show=false to clear the old cursor, once with argument show=true to draw the new one.
