The progress bar control com.sun.star.awt.UnoControlProgressBar displays a growing or shrinking bar to give the user feedback during an operation, for example, the completion of a lengthy task. The minimum and the maximum progress value of the control is set by the ProgressValueMin and the ProgressValueMax properties. The progress value is controlled by the ProgressValue property. By default, the progress bar is blue, but the fill color can be changed by setting the FillColor property. The functionality of a progress bar is demonstrated in the following example:
Sub ProgressBarDemo() Dim oProgressBar As Object, oProgressBarModel As Object Dim ProgressValue As Long REM progress bar settings Const ProgressValueMin = 0 Const ProgressValueMax = 40 Const ProgressStep = 4 REM set minimum and maximum progress value oProgressBarModel = oDialog.Model.ProgressBar1 oProgressBarModel.setRange( ProgressValueMin, ProgressValueMax ) REM show progress bar oProgressBar = oDialog.getControl("ProgressBar1") oProgressBar.setVisible( True ) REM increase progress value every second For ProgressValue = ProgressValueMin To ProgressValueMax Step ProgressStep oProgressBarModel.setValue( ProgressValue ) Wait 1000 Next ProgressValue REM hide progress bar oProgressBar.setVisible( False ) End Sub
