/**
|
|
* @short A progress indicator widget.
|
|
*
|
|
* KGameProgress is derived from TQFrame and TQRangeControl, so
|
|
* you can use all the methods from those classes. The only difference
|
|
* is that setValue() is now made a slot, so you can connect
|
|
* stuff to it.
|
|
*
|
|
* None of the constructors take line step and page step as arguments,
|
|
* so by default they're set to 1 and 10 respectively.
|
|
*
|
|
* The Blocked style ignores the textEnabled() setting and displays
|
|
* no text, since it looks truly ugly (and for other reasons). Signal
|
|
* percentageChanged() is emitted whenever the value changes so you
|
|
* can set up a different widget to display the current percentage complete
|
|
* and connect the signal to it.
