      protected void uninstallKeyboardActions()
      Unregisters keyboard actions.

    • getBaseline

      public int getBaseline​(JComponent c, int width, int height)
      Returns the baseline.
      Overrides:
      getBaseline in class ComponentUI
      Parameters:
      c - JComponent baseline is being requested for
      width - the width to get the baseline for
      height - the height to get the baseline for
      Returns:
      baseline or a value < 0 indicating there is no reasonable baseline
      Throws:
      NullPointerException - if c is null

      Overrides:
      getMinimumSize in class ComponentUI
      Parameters:
      c - the component whose minimum size is being queried; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components
      Returns:
      a Dimension object or null
      See Also:
      JComponent.getMinimumSize(), LayoutManager.minimumLayoutSize(java.awt.Container), ComponentUI.getPreferredSize(javax.swing.JComponent)

    • getPreferredSize
