TcxCustomProgressBar = class(
TcxCustomEdit
)
The TcxCustomProgressBar class is the ancestor of the TcxProgressBar, representing a progress bar control. It implements all the functionality needed by its descendant. The TcxProgressBar class simply publishes certain properties.
The primary features implemented by the TcxCustomProgressBar class are listed below:
Vertical orientation support (Properties.Orientation and Properties.TextOrientation);
Multiple fill styles support – solid, gradient, rectangles, bitmaps (Properties.BarStyle and Properties.ForegroundImage);
Marquee progress bar support – the bar can be animated to show activity instead of overall progress (Properties.Marquee, Properties.AnimationPath, Properties.AnimationRestartDelay, and Properties.AnimationSpeed);
Windows® Vista paint style support – the bar showing the completion progress is accentuated using an animated highlight (Properties.BarStyle, Properties.AnimationPath, Properties.AnimationRestartDelay, and Properties.AnimationSpeed);
Windows® 7 taskbar progress visualization support – the bar showing the completion or marquee progress is displayed in an application’s taskbar button via the TdxTaskbarProgress component linked to a progress bar control;
Overload bar support – the bar can be divided into two parts with different styles (Properties.ShowOverload);
Peak value support – the progress bar is capable of displaying a peak value (Properties.ShowPeak);
Three text label styles support – the progress bar can display its current position, a percentage, or arbitrary text (Properties.ShowTextStyle);
Windows® theme and skin support (Style.LookAndFeel.NativeStyle and Style.LookAndFeel.SkinName).
