\class TQSlider
|
|
|
|
\brief The TQSlider widget provides a vertical or horizontal slider.
|
|
|
|
|
|
|
|
\ingroup basic
|
|
|
|
\mainclass
|
|
|
|
|
|
|
|
The slider is the classic widget for controlling a bounded value.
|
|
|
|
It lets the user move a slider along a horizontal or vertical
|
|
|
|
groove and translates the slider's position into an integer value
|
|
|
|
within the legal range.
|
|
|
|
|
|
|
|
TQSlider inherits TQRangeControl, which provides the "integer" side
|
|
|
|
of the slider. setRange() and value() are likely to be used by
|
|
|
|
practically all slider users; see the \l TQRangeControl
|
|
|
|
documentation for information about the many other functions that
|
|
|
|
class provides.
|
|
|
|
|
|
|
|
The main functions offered by the slider itself are tickmark and
|
|
|
|
orientation control; you can use setTickmarks() to indicate where
|
|
|
|
you want the tickmarks to be, setTickInterval() to indicate how
|
|
|
|
many of them you want and setOrientation() to indicate whether the
|
|
|
|
slider is to be horizontal or vertical.
|
|
|
|
|
|
|
|
A slider accepts focus on Tab and uses the mouse wheel and a
|
|
|
|
suitable keyboard interface.
