+
+ @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.
