A Default size for a blank JList?

Jan 19th, 2006

Hello, I'm currently creating a PlayList for a media application I am working on. I'm using a JList as the GUI object for the PlayList and a DefaultListModel as the storage area to be held in the PlayList. I was hoping that if I was to pass a DefaultListModel object containing no information I could create a JList that had, lets say, 5 rows visible how that doesn't seem to be the case. Overall I'm hoping that I can have the playlist (JList) stay the same size whether their is data in the DefaultListModel or if it is completely empty (like a new playlist. Basically the playlist would sort of work like Winamp's. Below is some of the code I'm using:

playListPanel=new JPanel();
		playListPanel.setBorder(new TitledBorder("PlayList"));
		playListData=new DefaultListModel();
		playListDisplay=new JList();
		playListDisplay.setModel(playListData);
		playListDisplay.setFixedCellWidth(300);
		playListDisplay.setVisibleRowCount(5);
		playListDisplay.setDragEnabled(true);
 
		playListData.addElement("");
		//playListDisplay.setListData(playListData);
		scrollPane = new JScrollPane(playListDisplay,
						ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS,
						ScrollPaneConstants.HORIZONTAL_SCROLLBAR_NEVER);
		playListPanel.add(scrollPane);
playListPanel=new JPanel();
		playListPanel.setBorder(new TitledBorder("PlayList"));
		playListData=new DefaultListModel();
		playListDisplay=new JList();
		playListDisplay.setModel(playListData);
		playListDisplay.setFixedCellWidth(300);
		playListDisplay.setVisibleRowCount(5);
		playListDisplay.setDragEnabled(true);

		playListData.addElement("");
		//playListDisplay.setListData(playListData);
		scrollPane = new JScrollPane(playListDisplay,
						ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS,
						ScrollPaneConstants.HORIZONTAL_SCROLLBAR_NEVER);
		playListPanel.add(scrollPane);

Thanks in advance for the help

When you say size, are you referring to the visual aspect of the component? Cause having the size of a list with 5 elements when its empty doesn't make sense to me.
