JInternalFrame iconifying size

[John Jai]

Hi,

I would like to know how the Iconified size of a JInternalFrame added to a JDesktopPane (content pane of a JFrame) is calculated. I have a total of 4 internal frames. When the frame is on its initial size i open two of the internal frames and iconify them. The get iconified some what smaller. Now I just maximize and minimize the outer JFrame (either clicking the min/max button or pulling the borders) and then tried iconify the other two internal frames. Now the other two iconfied frames have a larger size than the first two.

Can any one please tell me whether when iconifying a internal frame what are the external factors taken into account. I have a custom desktop manager which does nothing on iconfication of its internal frames. I have attached the issue screen shot too.

public void iconifyFrame(JInternalFrame f) {	
			super.iconifyFrame(f);
		}

I resolved the issue by overriding iconifyFrame() method in DestopManager interface.

// Specify the height of the iconified internal frames
		int iconHeight = 28;
		
		@Override
		public void iconifyFrame(JInternalFrame f) {
			super.iconifyFrame(f);
			JDesktopIcon icon = f.getDesktopIcon();
			icon.setBounds(icon.getX(), icon.getY(), icon.getWidth(), iconHeight);
			
		}

This was giving better control with Y value of icons. Sometimes they were not aligned in a straight line.

		// Specify the height of the iconified internal frames
		int iconX = 0;
		int iconWidth = 160;
		int iconHeight = 28;

		@Override
		public void iconifyFrame(JInternalFrame f) {
			super.iconifyFrame(f);
			JDesktopIcon icon = f.getDesktopIcon();
                        //  desk is the JDesktopPane object
			int iconY = desk.getSize().height - iconHeight;
			icon.setBounds(iconX, iconY, iconWidth, iconHeight);
			// Calculate for next icon bounds
			iconX += iconWidth;			
			
		}

		@Override
		public void deiconifyFrame(JInternalFrame f) {
			super.deiconifyFrame(f);
			// Calculate for next icon bounds
			iconX = 0;
			for (JInternalFrame frame : desk.getAllFrames()){  
	            if (frame.isIcon()){  
	                JInternalFrame.JDesktopIcon icon = frame.getDesktopIcon();  
	                icon.setLocation(iconX, icon.getY());
	                iconX += iconWidth;
	            }  
	        }  
	}
