## Brief Introduction of Slider Control
The slider control is mainly visual realization to the adjustment logic of a
value. Through dragging and sliding the control, occasions of the users
adjusting the brightness and volume and operation of adjusting the value of a
certain range are more visual, avoiding the trouble of keyboard input.
- Hierarchical relation of slider control class
- [`mWidget`](MiniGUIProgGuidePart2Chapter04.md#mwidget)
* [`mSlider`](MiniGUIProgGuidePart2Chapter09.md#mslider)
* [`mTrackBar`](MiniGUIProgGuidePart2Chapter09.md#mtrackbar)
* [`mScrollBar`](MiniGUIProgGuidePart2Chapter09.md#mscrollbar)
* Control creating method
- Automatic creation: drag corresponding slider control through interface
designer in miniStudio, and miniStudio will automatically create control and
provide visual control configuration, and at the same time, creation codes are
generated automatically.
- Manual generation: according to mGNCS control creation process, through
programming, corresponding control window class ID is imported and control is
generated. Manual programming sets control property and event handling.
## mSlider
- *Control window class*: `NCSCTRL_SLIDER`
- *Control English name*: Slider
- *Brief introduction*: Basic class of slider series controls
- *Schematic diagram*:
_The control is abstract control and cannot be used directly._
