+ A slider is a control with a handle which can be pulled back and forth to
+ change the value.
On Windows, the track bar control is used.
@style{wxSL_VERTICAL}
Displays the slider vertically.
@style{wxSL_AUTOTICKS}
- Displays tick marks.
+ Displays tick marks. Windows only.
+ @style{wxSL_MIN_MAX_LABELS}
+ Displays minimum, maximum labels (new since wxWidgets 2.9.1).
+ @style{wxSL_VALUE_LABEL}
+ Displays value label (new since wxWidgets 2.9.1).
@style{wxSL_LABELS}
- Displays minimum, maximum and value labels.
+ Displays minimum, maximum and value labels (same as wxSL_VALUE_LABEL
+ and wxSL_MIN_MAX_LABELS together).
@style{wxSL_LEFT}
Displays ticks on the left and forces the slider to be vertical.
@style{wxSL_RIGHT}
@style{wxSL_SELRANGE}
Allows the user to select a range on the slider. Windows only.
@style{wxSL_INVERSE}
- Inverses the mininum and maximum endpoints on the slider. Not
+ Inverses the minimum and maximum endpoints on the slider. Not
compatible with wxSL_SELRANGE.
@endStyleTable
+ Notice that @c wxSL_LEFT, @c wxSL_TOP, @c wxSL_RIGHT and @c wxSL_BOTTOM
+ specify the position of the slider ticks in MSW implementation and that the
+ slider labels, if any, are positioned on the opposite side. So, to have a
+ label on the left side of a vertical slider, @b wxSL_RIGHT must be used (or
+ none of these styles at all should be specified as left and top are default
+ positions for the vertical and horizontal sliders respectively).
+
+ @beginEventEmissionTable{wxScrollEvent}
+ You can use EVT_COMMAND_SCROLL... macros with window IDs for when intercepting
+ scroll events from controls, or EVT_SCROLL... macros without window IDs for
+ intercepting scroll events from the receiving window -- except for this,
+ the macros behave exactly the same.
+ @event{EVT_SCROLL(func)}
+ Process all scroll events.
+ @event{EVT_SCROLL_TOP(func)}
+ Process @c wxEVT_SCROLL_TOP scroll-to-top events (minimum position).
+ @event{EVT_SCROLL_BOTTOM(func)}
+ Process @c wxEVT_SCROLL_BOTTOM scroll-to-bottom events (maximum position).
+ @event{EVT_SCROLL_LINEUP(func)}
+ Process @c wxEVT_SCROLL_LINEUP line up events.
+ @event{EVT_SCROLL_LINEDOWN(func)}
+ Process @c wxEVT_SCROLL_LINEDOWN line down events.
+ @event{EVT_SCROLL_PAGEUP(func)}
+ Process @c wxEVT_SCROLL_PAGEUP page up events.
+ @event{EVT_SCROLL_PAGEDOWN(func)}
+ Process @c wxEVT_SCROLL_PAGEDOWN page down events.
+ @event{EVT_SCROLL_THUMBTRACK(func)}
+ Process @c wxEVT_SCROLL_THUMBTRACK thumbtrack events
+ (frequent events sent as the user drags the thumbtrack).
+ @event{EVT_SCROLL_THUMBRELEASE(func)}
+ Process @c wxEVT_SCROLL_THUMBRELEASE thumb release events.
+ @event{EVT_SCROLL_CHANGED(func)}
+ Process @c wxEVT_SCROLL_CHANGED end of scrolling events (MSW only).

+ Process all scroll events.
+ @event{EVT_COMMAND_SCROLL_TOP(id, func)}
+ Process @c wxEVT_SCROLL_TOP scroll-to-top events (minimum position).

+ Process @c wxEVT_SCROLL_BOTTOM scroll-to-bottom events (maximum position).
+ @event{EVT_COMMAND_SCROLL_LINEUP(id, func)}

+
+ @section slider_diff The difference between EVT_SCROLL_THUMBRELEASE and EVT_SCROLL_CHANGED
+
+ The EVT_SCROLL_THUMBRELEASE event is only emitted when actually dragging the
+ thumb using the mouse and releasing it (This EVT_SCROLL_THUMBRELEASE event
+ is also followed by an EVT_SCROLL_CHANGED event).
+
+ The EVT_SCROLL_CHANGED event also occurs when using the keyboard to change
+ the thumb position, and when clicking next to the thumb
+ (In all these cases the EVT_SCROLL_THUMBRELEASE event does not happen).
+ In short, the EVT_SCROLL_CHANGED event is triggered when scrolling/ moving
+ has finished independently of the way it had started.
+ Please see the widgets sample ("Slider" page) to see the difference between
+ EVT_SCROLL_THUMBRELEASE and EVT_SCROLL_CHANGED in action.
