      • createUI

        public static ComponentUI createUI​(JComponent c)
        Constructs a new instance of BasicDesktopIconUI.

      • installUI

        public void installUI​(JComponent c)
        Description copied from class: ComponentUI
        Configures the specified component appropriately for the look and feel. This method is invoked when the ComponentUI instance is being installed as the UI delegate on the specified component. This method should completely configure the component for the look and feel, including the following:
        1. Install default property values for color, fonts, borders, icons, opacity, etc. on the component. Whenever possible, property values initialized by the client program should not be overridden.
        2. Install a LayoutManager on the component if necessary.
        3. Create/add any required sub-components to the component.
        4. Create/install event listeners on the component.
        5. Create/install a PropertyChangeListener on the component in order to detect and respond to component property changes appropriately.
        6. Install keyboard UI (mnemonics, traversal, etc.) on the component.
        7. Initialize any appropriate instance data.
        Overrides:
        installUI in class ComponentUI
        Parameters:
        c - the component where this UI delegate is being installed

        ComponentUI.uninstallUI(javax.swing.JComponent), JComponent.setUI(javax.swing.plaf.ComponentUI), JComponent.updateUI()
      • uninstallUI

        public void uninstallUI​(JComponent c)
        Description copied from class: ComponentUI
        Reverses configuration which was done on the specified component during installUI. This method is invoked when this UIComponent instance is being removed as the UI delegate for the specified component. This method should undo the configuration performed in installUI, being careful to leave the JComponent instance in a clean state (no extraneous listeners, look-and-feel-specific property objects, etc.). This should include the following:
        1. Remove any UI-set borders from the component.
        2. Remove any UI-set layout managers on the component.
        3. Remove any UI-added sub-components from the component.
        4. Remove any UI-added event/property listeners from the component.
        5. Remove any UI-installed keyboard UI from the component.
        6. Nullify any allocated instance data objects to allow for GC.
        Overrides:
        uninstallUI in class ComponentUI
        Parameters:
        c - the component from which this UI delegate is being removed; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components

      • installComponents

        protected void installComponents​()
        Registers components.
      • uninstallComponents

        protected void uninstallComponents​()
        Unregisters components.
      • installListeners

        protected void installListeners​()
        Registers listeners.
      • uninstallListeners

        protected void uninstallListeners​()
        Unregisters listeners.
      • installDefaults

        protected void installDefaults​()
        Installs default properties.
      • uninstallDefaults

        protected void uninstallDefaults​()
        Uninstalls default properties.
      • createMouseInputListener

        protected MouseInputListener createMouseInputListener​()
        Returns a new instance of MouseInputListener.
        Returns:
        a new instance of MouseInputListener
      • getPreferredSize

        public Dimension getPreferredSize​(JComponent c)
        Description copied from class: ComponentUI
        Returns the specified component's preferred size appropriate for the look and feel. If null is returned, the preferred size will be calculated by the component's layout manager instead (this is the preferred approach for any component with a specific layout manager installed). The default implementation of this method returns null.
        Overrides:
        getPreferredSize in class ComponentUI
        Parameters:
        c - the component whose preferred 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 containing given component's preferred size appropriate for the look and feel
        See Also:
        JComponent.getPreferredSize(), LayoutManager.preferredLayoutSize(java.awt.Container)
      • getMaximumSize

        public Dimension getMaximumSize​(JComponent c)
        Desktop icons can not be resized. Therefore, we should always return the minimum size of the desktop icon.
        Overrides:
        getMaximumSize in class ComponentUI
        Parameters:
        c - the component whose maximum 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:
        getMinimumSize(javax.swing.JComponent)
      • getInsets

        public Insets getInsets​(JComponent c)
        Returns the insets.
        Parameters:
        c - a component
        Returns:
        the insets
      • deiconize

        public void deiconize​()
        De-iconifies the internal frame.
