<h1>Class Description</h1>
|
|
<p>
|
|
|
|
An NSSliderCell controls the behaviour and appearance of an
|
|
associated NSSlider, or a single slider in an
|
|
NSMatrix. Tick marks are defined in the official
|
|
standard, but are not implemented in GNUstep.
|
|
</p>
|
|
<p>
|
|
|
|
An NSSliderCell can be customized through its
|
|
<code>set...</code> methods. If these do not provide
|
|
enough customization, a subclass can be created, which
|
|
overrides any of the follwing methods:
|
|
<code>knobRectFlipped:</code>,
|
|
<code>drawBarInside:flipped:</code>,
|
|
<code>drawKnob:</code>, or
|
|
<code>prefersTrackingUntilMouseUp</code>.
