TTaskDialogProgressBar.Position property
Contains the current position for the progress bar.
Declaration
property Position: Integer read FPosition write SetPosition default 0;Description
Position is an
Integer property which indicates the
current position on the progress bar. Position and Max are used to calculate
the completion percentage for the progress bar. The default value for the
property is 0 (zero).
The value in Position must be in the range Min..Max inclusive. If Position is set to a value which exceeds the allowed range, it is normalized to the Min or Max value as needed.
Changing the value in the property causes a TDM_SET_PROGRESS_BAR_POS message to be sent using the Handle for the task dialog. This allows the widgetset class to be notified when the progress bar needs to be redrawn. The message is not sent to the dialog if tfShowProgressBar has not been included in its Flags property or the Handle for the dialog has not been assigned.
Use Min to set the lower limit for the value in Position.
Use Max to set the upper limit for the value in Position.
Position, Min, and Max are not used when the task dialog is configured to use the marquee drawing style for its progress bar.
