Calculate actual progress bar's foreground width

[Markov]

Hello.
I'm trying to calculate width of progress bar foreground with NGUIMath.CalculateRelativeWidgetBounds, but it returns original size of this texture. So how to calculate actual size?
UPD: this foreground is a sliced texture so i can't just multiply original size of texture by progressBar.value.

UIWidget.drawingDimensions is what determines the actual dimensions clipped by the Draw Region setting. Alternatively you have to take UIWidget.drawRegion into consideration yourself.
