# TCustomProgressBar.ApplyChanges

ApplyChanges - apply any changes that have occurred.

## Declaration

Source position: comctrls.pp line 1840

`protected procedure TCustomProgressBar.ApplyChanges;`

## Description

ApplyChanges is a method used to apply property values from the progress bar to the widgetset class.

Values in the Min, Max, and Position properties are normalized; i. e. Min <= Position <= Max. When the Handle has been allocated for the control, the values are applied to the widgetset class by calling its ApplyChanges method.

No actions are performed in the method when the component is being loaded using the LCL streaming mechanism.

ApplyChanges is called when the Handle is created (or re-created) in InitializeWnd, and from the Loaded method when component streaming has been completed. It is also called when values in properties are changed, including: Min, Max, Position, Step, Orientation, Smooth, and BarShowText.
