Confused with JInternalFrame class

[Truster]

Hello friends,

I am beginner to the field of java programming language. Because of that I have lots of confusion about the class concepts of java. I am getting troubled while understanding the 'JInternalFrame class' of the java programming. I don't have any idea bout the use of this java class. Do you have enough knowledge about the 'JInternalFrame class' of java? If yes then please let me know the same. I am waiting for your reply.

Hi,

A JInternalFrame class is a lightweight object that provides many of the features of a native frame, including dragging, closing, becoming an icon, resizing, title display, and support for a menu bar. Generally, you add JInternalFrames to a JDesktopPane. The UI delegates the look-and-feel-specific actions to the DesktopManager object maintained by the JDesktopPane. The JInternalFrame content pane is where you add child components.

Please review following constructors of JInternalFrame class:

• JInternalFrame(String ttl, boolean resizable, boolean clsable, boolean maximizable, boolean icnifiable)
• JInternalFrame(String ttl, boolean resizable, boolean clsable, boolean maximizable)
• JInternalFrame(String ttl, boolean resizable, boolean clsable)
• JInternalFrame(String ttl, boolean resizable)
• JInternalFrame(String ttl)

Example of JInternalFrame class:

import javax.swing.JInternalFrame;
import javax.swing.JDesktopPane;

public class JInternalFrameMain {
  public static void main(String[] argzv) throws Exception
 {
    JDesktopPane desktopQ = new JDesktopPane();
    JInternalFrame[] framesZZ = desktopQ.getAllFrames();

    for (int iZ = 0; iZ < framesZ.length; iZ++) 
{
      String titleZ = framesZZ[iZ].getTitle();
      boolean isVisible = framesZZ[iZ].isVisible();
      boolean isCloseable = framesZ[iZ].isClosable();
      boolean isResizeable = framesZ[iZ].isResizable();
      boolean isIconifiable = framesZ[iZ].isIconifiable();
      boolean isIcon = framesZ[i].isIcon();
      boolean isMaximizable = framesZ[iZ].isMaximizable();
      boolean isSelected = framesZ[iZ].isSelected();
    }
  }
}

Hi friend,

Following methods will definitely help you to know about the JInternalFrame class functionality:

1. setUI(InternalFrameUI fui)
2. setSelected(boolean sltd)
3. setRootPaneCheckingEnabled(boolean enbld)
4. setRootPane(JRootPane rt)
5. setMaximum(boolean bl)
6. setLayout(LayoutManager mgr)

Hello friend

Following java example will depict you the use of 'isClosable()' method of the JInternalFrame class:

import javax.swing.JInternalFrame;

public class JInternalFR {
  public static void main(String[] argev) throws Exception {
    JDesktopPane dp = new JDesktopPane();
    JInternalFrame[] pn = desktop.getAllFrames();

    for (int b = 0; b < pn.length; b++) 

{
      String title = pn[i].getTitle();
      boolean isVisible = pn[i].isVisible();
      boolean isCloseable = pn[i].isClosable();
      boolean isResizeable = pn[i].isResizable();
      boolean isIconifiable = pn[i].isIconifiable();
      boolean isIcon = pn[i].isIcon();
      boolean isMaximizable = pn[i].isMaximizable();
      boolean isSelected = pn[i].isSelected();
    }
  }
}
