NAME

6       wxSlider - Functions for wxSlider class
7

DESCRIPTION

9       A  slider is a control with a handle which can be pulled back and forth
10       to change the value.
11
12       On Windows, the track bar control is used.
13
14       On GTK+, tick marks are only available for version 2.16 and later.
15
16       Slider generates the same events as wxScrollBar  but  in  practice  the
17       most  convenient  way  to  process  wxSlider updates is by handling the
18       slider-specific wxEVT_SLIDER event which  carries  wxCommandEvent  con‐
19       taining just the latest slider position.
20
21       Styles
22
23       This class supports the following styles:
24
25       The difference between EVT_SCROLL_THUMBRELEASE and EVT_SCROLL_CHANGED
26
27       The  EVT_SCROLL_THUMBRELEASE  event is only emitted when actually drag‐
28       ging the thumb using the mouse and releasing it (This  EVT_SCROLL_THUM‐
29       BRELEASE event is also followed by an EVT_SCROLL_CHANGED event).
30
31       The  EVT_SCROLL_CHANGED  event  also  occurs when using the keyboard to
32       change the thumb position, and when clicking next to the thumb (In  all
33       these  cases  the  EVT_SCROLL_THUMBRELEASE  event  does not happen). In
34       short, the EVT_SCROLL_CHANGED event is triggered when scrolling/ moving
35       has  finished  independently  of the way it had started. Please see the
36       page_samples_widgets ("Slider" page)  to  see  the  difference  between
37       EVT_SCROLL_THUMBRELEASE and EVT_SCROLL_CHANGED in action.
