/**
|
|
* @short A TQLabel with option for a buddy radio button.
|
|
*
|
|
* The Label class provides a text display, with special behaviour when a radio
|
|
* button is set as a buddy.
|
|
*
|
|
* The Label object in effect acts as if it were part of the buddy radio button,
|
|
* in that when the label's accelerator key is pressed, the radio button receives
|
|
* focus and is switched on. When a non-radio button is specified as a buddy, the
|
|
* behaviour is the same as for TQLabel.
