|
|
||
|
|
The TQSlider widget provides a vertical or horizontal slider.
|
||
|
|
<p>
|
||
|
|
|
||
|
|
<p> 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.
|
||
|
13 years ago
|
<p> TQSlider inherits <a href="ntqrangecontrol.html">TQRangeControl</a>, which provides the "integer" side
|
||
|
|
of the slider. <a href="ntqrangecontrol.html#setRange">setRange</a>() and <a href="#value">value</a>() are likely to be used by
|
||
|
|
practically all slider users; see the <a href="ntqrangecontrol.html">TQRangeControl</a>
|
||
|
13 years ago
|
documentation for information about the many other functions that
|
||
|
|
class provides.
|
||
|
|
<p> The main functions offered by the slider itself are tickmark and
|
||
|
|
orientation control; you can use <a href="#setTickmarks">setTickmarks</a>() to indicate where
|
||
|
|
you want the tickmarks to be, <a href="#setTickInterval">setTickInterval</a>() to indicate how
|
||
|
|
many of them you want and <a href="#setOrientation">setOrientation</a>() to indicate whether the
|
||
|
|
slider is to be horizontal or vertical.
|
||
|
|
<p> A slider accepts focus on Tab and uses the mouse wheel and a
|
||
|
|
suitable keyboard interface.
