Examples of org.eclipse.swt.custom.StyledText.redraw()

org.eclipse.swt.custom.StyledText.redraw()

Causes the entire bounds of the receiver to be marked as needing to be redrawn. The next time a paint request is processed, the control will be completely painted.

Recalculates the content width for all lines in the bounds. When a LineStyleListener is used a redraw call is the only notification to the widget that styles have changed and that the content width may have changed.

@exception SWTException

ERROR_WIDGET_DISPOSED - if the receiver has been disposed
ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver
