[JAVA] Frame di frame!

[Oiziorbaf]

No, esiste:

direttamente dal sito della sun:

With the JInternalFrame class you can display a JFrame-like window within another window. Usually, you add internal frames to a desktop pane. The desktop pane, in turn, might be used as the content pane of a JFrame. The desktop pane is an instance of JDesktopPane, which is a subclass of JLayeredPane that has added API for managing multiple overlapping internal frames. 

You should consider carefully whether to base your program's GUI around frames or internal frames. Switching from internal frames to frames or vice versa isn't necessarily a simple task. By experimenting with both frames and internal frames, you can get an idea of the tradeoffs involved in choosing one over the other. 

Here is a picture of an application that has two internal frames (one of which is iconified) inside a regular frame:

e questo è il modo per usarlo:

The following code, taken from InternalFrameDemo.java, creates the desktop and internal frames in the previous example. 

...//In the constructor of InternalFrameDemo, a JFrame subclass:
    desktop = new JDesktopPane();
    createFrame(); //Create first window
    setContentPane(desktop);
    ...
    //Make dragging a little faster but perhaps uglier.
    desktop.setDragMode(JDesktopPane.OUTLINE_DRAG_MODE);
...
protected void createFrame() {
    MyInternalFrame frame = new MyInternalFrame();
    frame.setVisible(true); //necessary as of 1.3
    desktop.add(frame);
    try {
        frame.setSelected(true);
    } catch (java.beans.PropertyVetoException e) {}
}

...//In the constructor of MyInternalFrame, a JInternalFrame subclass:
static int openFrameCount = 0;
static final int xOffset = 30, yOffset = 30;

public MyInternalFrame() {
    super("Document #" + (++openFrameCount),
          true, //resizable
          true, //closable
          true, //maximizable
          true);//iconifiable
    //...Create the GUI and put it in the window...
    //...Then set the window size or call pack...
    ...
    //Set the window's location.
    setLocation(xOffset*openFrameCount, yOffset*openFrameCount);
}

Appunto... si parla di JInternalFrame e JDesktopPane, non JDesktopFrame. Quelli li conoscevo anch'io!

Grazie!

Ciao.
