      public CustomText(org.eclipse.swt.widgets.Composite parent, int style, int errorDectorationPos, String errorMsg)
      Creates a new instance of this class given its parent and a style values describing its behavior and a behavior error decorator for this component.
      Parameters:
      parent - a composite control which will be the parent of the new instance (cannot be null)
      style - the style of control to construct
      errorDectorationPos - the position of the error decorator
      errorMsg - the string for tooltip that will be shown as error message

    • CustomText

      public CustomText(org.eclipse.swt.widgets.Composite parent, int style, String errorMsg)
      Creates a new instance of this class given its parent, a style value describing its behavior and appearance, a string for error decorator.

      In contrast to #HeightBoundedText(Composite, int, int, String) constructor it constructs this component with error decorator that located at top-left.

      Parameters:
