<h1>class Slider(<a href="Control.html">Control</a>)</h1>
|
|
A Slider is a control that allows a user to select a value by dragging
|
|
a knob along a scale. The range of values may be either discrete or
|
|
continuous, and an action may be specified to be invoked whenever the
|
|
user changes the value.<br>
|
|
<h2>Constructor</h2>
|
|
<div style="margin-left: 40px;">
|
|
<dl>
|
|
<dt style="font-family: monospace;">Slider(orient)</dt>
|
|
<dd>Constructs a Slide with the specified orientation, 'h' for horizontal and 'v' for vertical.<br>
|
|
Note: On some platforms, the orientation of the slider is determined by
|
|
its relative width and height; on such platforms, the orient parameter
|
|
is ignored. For maximum portability, ensure that the dimensions of the
|
|
control and the orient parameter are in agreement with each other.</dd>
