Introduction

We think about developing an advanced TrackBar (Slider) control that supports MAC Style and many other features in the time working in ‘MAC-UI Suite' project (a project focus on building a rich library of UI controls with MAC style for .NET).

Main Features

  • Supports MAC style
  • Vertical and Horizontal trackbar
  • Supports many Text Tick styles: None, TopLeft, BottomRight, Both
  • You can change Text Font, ForeColor for Text Tick
  • Supports many Tick styles: None, TopLeft, BottomRight, Both
  • You can change TickColor, TickFrequency, TickHeight
  • You can change TrackerColor and TrackerSize
  • You can change TrackLineColor and TrackLineHeight
  • Easy to Use and Integrate in Visual Studio .NET
  • 100% compatible to the standard control in VS.NET
  • 100% managed code

To explore features of this TrackBar control, just download and run the demo program.

Control Methods

Methods Description
Decrement Call the Decrement() method to decrease the value displayed by an integer you specify
Increment Call the Increment() method to increase the value displayed by an integer you specify
OnScroll Raises the Scroll event.
OnValueChanged Raises the ValueChanged event.
ResetAppearance Reset the appearance properties after the UIStyle property.
SetRange Sets the minimum and maximum values for a TrackBar.

Control Events

Event Description
Scroll Occurs when either a mouse or keyboard action moves the slider.
ValueChanged Occurs when the property Value has been changed.

Using the Control

  • Download the source code and unzip it.
  • Open VS.NET's Tool menu and select "Add/Remove ToolBox Items".
  • Click "Browse", and navigate to the MACTrackBar.dll in the bin\Release directory of the source code.
  • Click Open and then OK, the MACTrackBar control will now be in your ToolBox. Just drag the control onto your form to use it.
  • Set the control's properties, and coding an event handle, and you press F5 to run your program.

Inside the Code

The calculation for all Orientation of the Tracker may be fairly complex and interesting.

Please read the below methods for more detail:

  • DrawTickTextLine()
  • DrawTickLine()
  • OnMouseDownSlider()
  • OnMouseUpSlider()
  • OnMouseMoveSlider()

Conclusion

Basing on this core code, you can build quite easily other UI Style for the TrackBar (e.g. XP Style...). You can draw the Tracker of any style by loading pictures...

We can support easily all tracker shapes as on MAC (by loading and drawing tracker's pictures). However, to optimize the memory usage, currently I didn't add them.

I hope others find this control useful. Please feel free to report errors, issues, or requests.
