initialize the panel that holds the cards cards = new JPanel(new CardLayout()) //they get String names here cards.add(card1, PANEL_ONE) cards.add(card2, PANEL_TWO) //Now to show a card, you get the layout from the cards JPanel CardLayout layout = (CardLayout)(cards.getLayout()) //call the show() method and pass it the String name layout.show(cards, PANEL_TWO) now make each card, which is just a JPanel JPanel card1 = new JPanel() JPanel card2 = new JPanel() //.
create a panel to hold all the cards JPanel cards final static String PANEL_ONE = "My first panel" final static String PANEL_TWO = "My second panel" //. In fact, using a tabbed pane is easier than using card layout, because a JTabbedPane implements its own layout.įollowing are the steps to make this layout go:

Note that Swing also gives you for free the tabbed pane, which is covered next with an illustrative example in case you need that kind of specific functionality. This is useful in working with weezards (step-by-step panels the user must go through). The CardLayout class offers a set of methods to flip through the cards sequentially, or to show a particular card to show a panel based on its String name. As with much in Swing programming, the order of invocation matters the first panel added to the layout is what is displayed when the frame is first shown. Just as with a deck of cards, only one card is visible at a time. Case: CARD LAYOUT:Ī card layout treats each component in the container as a card on a stack. It is common to nest layouts to get the functionality, flexibility, and control required. You can nest a grid layout inside a box layout inside a flow layout if you want. But you don't have to nest layouts of the same type.

Note that we have nested layouts of the same kind here to demonstrate how to do it so you get the control you need. One box layout nested within another allows more sophistication. * * Eben Hewitt **/ public class FlowLayoutExample //end NestedBoxLayoutįigure 25.5. Package .layouts import import import /** * Shows how to use a FlowLayout * with an alignment and horizontal and * vertical gaps * between each component.
The horizontal and vertical gap parameters allow you to specify the number of pixels to put between each component. SwingUtilities.Public FlowLayout(int alignment, int horizontalGap, int verticalGap) The problem is when the JTable has more rows, in this case the vertical scrollbar will appear, but the scroll pane will "shrink": This result can be achieved using the below code, you only need to change this line of code: Object data = new Object

The JPanel is wider because in my application it will be part of a CardLayout, so the other cards width and height will determine this panel size (in the code below i'm overriding getPreferredSize method for convenience, but i don't want to use it). This is a screenshot of what i want to achieve: I'm using some code found on SO to set the table preferred width according to its content (i'm also overrding JTable's getPreferredScrollableViewportSize method). I have an issue trying to fill vertically a JScrollPane (which contains a JTable) inside a JPanel: the panel should not be filled horizontally, instead, the JScrollPane should take only the "necessary" space.
