Java Swing Split pane view layout

Question

Hello im implementing my firs split pane view and it doesn't seem to be working for me and i get the following output...

Here is the code.

//Create Album Panel
    albumPanel.setLayout(new FlowLayout());

    //Add List view
    albumList.setMinimumSize (new Dimension(150,150));
    albumPanel.add(new JScrollPane(albumList));


    //Add Text Area
    textArea.setLineWrap(true);
    textArea.setWrapStyleWord(true);
    textArea.setEditable(false);
    textArea.setMinimumSize (new Dimension(150,150));
    albumPanel.add(textArea);

    //Split Pane
    JSplitPane splitpane = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, albumList, textArea);

    albumPanel.add(splitpane, BorderLayout.CENTER);

Answer 1

You have set your albumPanel layout to FlowLayout but you try and use a BorderLayout constants when adding to the JSplitPane:

albumPanel.add(splitpane, BorderLayout.CENTER);

you should rather set the albumPanel layout to BorderLayout via new BorderLayout()

Also it is not a good idea for you to set the size of your components let the LayoutManager's do it for you.

Answer 2

You need to add components, the JScrollPanes that hold your list and your text area, to your JSplitPane for it to show them. And yeah as David states (1+ to him), your container that holds the JSplitPane needs to be able to let it expand, and BorderLayout would work well for this.

Also, don't add components to a container more than once. Add your components to the JScrollPanes, then add the JScrollPanes to the JSplitPane. Don't also add the components to the albumPanel container. Your code is a bit schizophrenic in this regard.
