Description

This action changes background (Color, BackgroundBitmap, BackgroundStyle) and "padding" (LeftMargin, TopMargin, RightMargin, BottomMargin) properties of TCustomRichViewEdit controls. "Padding" can be changed only if CanChangeMargins=True.

These changes are not editing operations and so they cannot be undone. However, if rvfoSaveBack and/or rvfoSaveLayout are included in TCustomRichViewEdit.RVFOptions property, the action calls TCustomRichViewEdit.Change, so its Modified property becomes True.

The action calls the following events:

•TCustomRichViewEdit.OnChange (called by TCustomRichViewEdit.Change, see above)

•TRVAControlPanel.OnMarginsChanged (only if the action changed values of LeftMargin, TopMargin, RightMargin, BottomMargin properties of TCustomRichViewEdit)

•OnChange

•TRVAControlPanel.OnBackgroundChange
