BitmapTrackBar¶

Qualified name: delphifmx.BitmapTrackBar

class BitmapTrackBar¶

Bases: TrackBar

Represents a track bar similar to that implemented by TTrackBar. TBitmapTrackBar is not registered to the IDE, thus it cannot be dragged and dropped from the tool palette. You can manually instantiate such component, override the constructor, and create a track bar that can display bitmaps. TBitmapTrackBar is intended for component designers as a base component for other custom track bars. Use TTrackBar in applications, instead.
