It is possible to remove some RichTextEditor control bar with showControlBar property.
But how to remove title bar too?
The following code displays control WITH empty title bar:
<mx:RichTextEditor id="mLog" left="10" right="10" top="10" bottom="41"
dropShadowVisible="false" showControlBar="false">
How’s this look?
headerHeightsets the title bar height to 0. The 4borderThicknessXXXsettings remove the borders that still showed.
