\section{\class{wxSlider}}\label{wxslider}
|
|
|
|
A slider is a control with a handle which can be pulled
|
|
back and forth to change the value.
|
|
|
|
In Windows versions below Windows 95, a scrollbar is used to simulate the slider. In Windows 95,
|
|
the track bar control is used.
|
|
|
|
Slider events are handled in the same way as a scrollbar.
