Interface DesktopManager

  • All Known Implementing Classes:
    DefaultDesktopManager


    public interface DesktopManager
    DesktopManager objects are owned by a JDesktopPane object. They are responsible for implementing L&F specific behaviors for the JDesktopPane. JInternalFrame implementations should delegate specific behaviors to the DesktopManager. For instance, if a JInternalFrame was asked to iconify, it should try:
        getDesktopPane().getDesktopManager().iconifyFrame(frame);
     
    This delegation allows each L&F to provide custom behaviors for desktop-specific actions. (For example, how and where the internal frame's icon would appear.)

    This class provides a policy for the various JInternalFrame methods, it is not meant to be called directly rather the various JInternalFrame methods will call into the DesktopManager.

    • Method Detail

      • openFrame

        void openFrame(JInternalFrame f)
        If possible, display this frame in an appropriate location. Normally, this is not called, as the creator of the JInternalFrame will add the frame to the appropriate parent.
      • closeFrame

        void closeFrame(JInternalFrame f)
        Generally, this call should remove the frame from it's parent.
      • maximizeFrame

        void maximizeFrame(JInternalFrame f)
        Generally, the frame should be resized to match it's parents bounds.
      • minimizeFrame

        void minimizeFrame(JInternalFrame f)
        Generally, this indicates that the frame should be restored to it's size and position prior to a maximizeFrame() call.
      • iconifyFrame

        void iconifyFrame(JInternalFrame f)
        Generally, remove this frame from it's parent and add an iconic representation.
      • deiconifyFrame

        void deiconifyFrame(JInternalFrame f)
        Generally, remove any iconic representation that is present and restore the frame to it's original size and location.
      • activateFrame

        void activateFrame(JInternalFrame f)
        Generally, indicate that this frame has focus. This is usually called after the JInternalFrame's IS_SELECTED_PROPERTY has been set to true.
      • deactivateFrame

        void deactivateFrame(JInternalFrame f)
        Generally, indicate that this frame has lost focus. This is usually called after the JInternalFrame's IS_SELECTED_PROPERTY has been set to false.
      • beginDraggingFrame

        void beginDraggingFrame(JComponent f)
        This method is normally called when the user has indicated that they will begin dragging a component around. This method should be called prior to any dragFrame() calls to allow the DesktopManager to prepare any necessary state. Normally f will be a JInternalFrame.
      • dragFrame

        void dragFrame(JComponent f,
                       int newX,
                       int newY)
        The user has moved the frame. Calls to this method will be preceded by calls to beginDraggingFrame(). Normally f will be a JInternalFrame.
      • endDraggingFrame

        void endDraggingFrame(JComponent f)
        This method signals the end of the dragging session. Any state maintained by the DesktopManager can be removed here. Normally f will be a JInternalFrame.
      • beginResizingFrame

        void beginResizingFrame(JComponent f,
                                int direction)
        This methods is normally called when the user has indicated that they will begin resizing the frame. This method should be called prior to any resizeFrame() calls to allow the DesktopManager to prepare any necessary state. Normally f will be a JInternalFrame.
      • resizeFrame

        void resizeFrame(JComponent f,
                         int newX,
                         int newY,
                         int newWidth,
                         int newHeight)
        The user has resized the component. Calls to this method will be preceded by calls to beginResizingFrame(). Normally f will be a JInternalFrame.
      • endResizingFrame

        void endResizingFrame(JComponent f)
        This method signals the end of the resize session. Any state maintained by the DesktopManager can be removed here. Normally f will be a JInternalFrame.
      • setBoundsForFrame

        void setBoundsForFrame(JComponent f,
                               int newX,
                               int newY,
                               int newWidth,
                               int newHeight)
        This is a primitive reshape method.
