Interface IInformationControlExtension5

    • Method Detail

      • containsControl

        boolean containsControl​(Control control)
        Tests whether the given control is this information control or a child of this information control.
        Parameters:
        control - the control to test
        Returns:
        true iff the given control is this information control or a child of this information control
      • isVisible

        boolean isVisible()
        Returns:
        true iff the information control is currently visible
      • computeSizeConstraints

        Point computeSizeConstraints​(int widthInChars,
                                     int heightInChars)
        Computes the width- and height constraints of the information control in pixels, based on the given width and height in characters. Implementors should use the main font of the information control to do the characters-to-pixels conversion. This is typically the dialog font.
        Parameters:
        widthInChars - the width constraint in number of characters
        heightInChars - the height constraint in number of characters
        Returns:
        a point with width and height in pixels, or null to use the subject control's font to calculate the size
      • getInformationPresenterControlCreator

        IInformationControlCreator getInformationPresenterControlCreator()
        Returns the rich information control creator for this information control.

        The returned information control creator is used to create an enriched version of this information control, e.g. when the mouse is moved into this control and it needs to be enriched or when it needs to be made sticky for other reasons.

        The returned information control creator must create information controls that implement IInformationControlExtension3 and IInformationControlExtension2, and whose IInformationControlExtension2.setInput(Object) accepts all inputs that are also supported by this information control.

        Note that automatic enriching of this information control works only if it also implements IInformationControlExtension3.

        This method may be called frequently, so implementors should ensure it returns quickly, e.g. by caching the returned creator.

        Returns:
        the information presenter control creator or null to disable enriching
