\brief
StaticText class for the FalagardBase module.
This class requires LookNFeel to be assigned. The LookNFeel should provide the following:
States:
- Enabled - basic rendering for enabled state.
- Disabled - basic rendering for disabled state.
- EnabledFrame - frame rendering for enabled state
- DisabledFrame - frame rendering for disabled state.
- WithFrameEnabledBackground - backdrop rendering for enabled state with frame enabled.
- WithFrameDisabledBackground - backdrop rendering for disabled state with frame enabled.
- NoFrameEnabledBackground - backdrop rendering for enabled state with frame disabled.
- NoFrameDisabledBackground - backdrop rendering for disabled state with frame disabled.
Named Areas (missing areas will default to 'WithFrameTextRenderArea'):
WithFrameTextRenderArea
WithFrameTextRenderAreaHScroll
WithFrameTextRenderAreaVScroll
WithFrameTextRenderAreaHVScroll
NoFrameTextRenderArea
NoFrameTextRenderAreaHScroll
NoFrameTextRenderAreaVScroll
NoFrameTextRenderAreaHVScroll
