CardLayout Problems
When switching cards using the show() method some of the contents of the card is not shown. On the card that has the problem I have a JSplitPane with two JScrollPane's in the JSplitPane. In the JScrollPane's I use a JPanel with the null layout. The contents of the JScrollPane do not appear. If I start the applet showing the card with the problem everything shows fine. If I start the applet showing another card and then switch to the card in question this is when the problem occurs. Any advice would be greatly appreciated.
Hey thanks for the response, I never thought anyone would touch this >one. :) you rock.np, that's what the forum is here for. And after all I'm just TRYING to help...;)
according to what you said it really seems to be a resizing prob, 'cause
Have you ever tried starting the applet with the
prob-card on top, switching to another one and then
switching back? what happens, the card is still ok?Yes, and everything is fine. this speaks quite in it's favor....
If the applet does not change size however, no matter what card you start it with, this (could) mean two things (assuming that it is, in fact, a resizing problem):
first possibiliy: other components within the card are resized to their downside when sarting with the prob-causing card so that it has enough space, when starting with the 'standard'-one they are not scaled down not leaving place for the rpob-causing card.
second: it has to do with the embedding in the html environment, I mean, the size of the area grantet to the applet is absolutely constant, and when starting with the prob-causer a bit of the applets'border is cut off, just like putting a picture frame over a too big photograph...
As for the second (possible) case: try to alter the embedding settings, in order to leave enough space to the applet or someting...
And for the first:...well, I know it's a vague advice but...try to remove ANY other items from the applet leaving just the cards, and play around with it....
I'll post as soon as something more productive crosses my mind..(but that will be after the xmas vacation, I guess ;D
btw.: ever tried to run the same applet in a tabbed pane instead of the card layout and see what happens?
p.s:merry xmas, so long...

Hi friends,
I am building a Swing GUI, i have a cardlayout managment, my GUI is dynamic that is every certain period of time new data are coming and new figures are being drawn in my GUI. The GUI containes menus, when you press on any menu list of items are listed for you, when you press on an item a page opens, when you press on another item, a new page opens, those pages are layouted in a cardlayout managment, each page is in top of another. I am getting a problem, when i am opening page 2 for example, and a new set of data comes in and the figure in page 1 is updated, i am automatically moved from page 1 to page 2 where the update happened, although i didn't press the item in the menu to go to that page where the update happened, please would anyone suggest me something, it is very urgent, and if someone wants the code i can supply it for sure, thanks for the help.Maybe an itemStateChanged -Event is invoked when the page is updated.

CardLayout problem. This is totally weird....
Hi...
I have some code which uses a CardLayout to show two different panels. Card A is a "loading" type panel telling the user to wait as background stuff is being done. Card B displays data from the database.
showCardA()
do some stuff.... (get data from database which takes around 5 seconds)
showCardB()
For some strange reason, card A is never shown. If I comment out showCardB(), card A is displayed correctly. The database call is about 5 seconds so it's not flipping through too quickly.
I am using CardLayout correctly, but I am thinking that the problem has something to do with threading issues?????
This bug is totally totally baffling me.You're blocking the event dispatch thread with your database stuff.
See http://spin.sourceforge.net for an explanation and a possible solution.

CardLayout : problem on previous card
I have a frame that is composed of several panels. One of those is a DisplayPanel for displaying drawings. I use CardLayout to display the drawings. Therefore, the uses can click on the next/previous button to look at the next/previous card of drawing that is shown in the displayPanel. I test the "next" button, and it works okay.
However, when I click on the "previous button", it DOES NOT show the exact drawings that I have before navigating to the next card.
Does anyone have any clue on why this will happen and how can I fix that?
Here's the skeleton of my coding:
public class drawMap extends JPanel
// variable declaration
public drawMap(Vector mapData, int index)
public Dimension getPreferredSize()
return new Dimension(width, height);
public void paintComponent(Graphics g)
// loop throught the mapData vector starting from the
// given index that is got from the constructor
// draw two rows
public class DisplayPanel extends JPanel implements ActionListener
private JButton previousButton, nextButton;
private JPanel allMaps = new JPanel(new CardLayout());
DisplayPanel()
add(mapPanel);
add(buttonPanel);
private JPanel mapPanel()
int i=0, cardIndex=0;
while (i < mapData.size())
DrawMap map = new DrawMap(mapData, i)
allMaps.add(map, String.valueOf(cardIndex));
i = findNextIndex(); // find the next index to start for the mapData
cardIndex++;
private JPanel buttonPanel()
JPanel p = new JPanel();
previousButton = new JButton("Previous");
previousButton.addActionListener(this);
nextButton = new JButton("Next");
nextButton.addActionListener(this);
p.add(previousButton);
p.add(nextButton);
return p;
private int findNextIndex()
// find the next index to start
public void actionPerformed(ActionEvent event)
Object source = event.getSource();
CardLayout cards = (CardLayout) (allMaps.getLayout());
if (source == previousButton)
cards.previous(allMaps);
else if (source == nextButton)
cards.next(allMaps);
}Sorry for the long code. I minimize it as much as I can.

}When i do run the above code, i do not get cards at the center although i have specified panel.add(cards,BorderLayout.CENTER);
Moreover cards.getLayout returns LayoutManager hence casting required, but i cant understand the reason why is it so, since i have specified cards with CardLayout in the constructorOK, I now understand your query.
(see if I can get the explanation correct)
LayoutManager is an interface, so only one method needs to be written for getLayout().
if the method was to return CardLayout
public CardLayout getlayout()...
you would need a method written for all the LayoutManagers, then a rewrite
for future LayoutManagers.
as is, its' just the one method, with a cast.
Hope there is some accuracy in this -

Problem with JPanel, CardLayout and Applets
Hello All,
I have a JPanel with a CardLayout as layout manager. In this JPanel i'm gonna show a few applets.
My problem is when i'm showing an applet for second time and try to click a button it does nothing... I think the action method is not called again...
How can i solve this?
Thanks in advance ; )Here is a few parts of my code...
public class InitAll{
JPanel cards = new JPanel( new CardLayout() );
JComboBox selector = new JComboBox();
Object objetosV[][] ={
{"Ventas",venta.class},
{"Compras",compras.class}, //These are applets.
{"Traspasos",traspasos.class},
{"Facturas",factura.class},
public void load( Applet app ){
cards.removeAll();
selector.removeAll();
cards.add( "Entrada", app );
selector.addItem( "Entrada" );
for ( int i=0; i < objetosV.length; i++ ){
selector.addItem( (String)objetosV[0] );
Applet temp=createPanel( ( Class ) objetosV[i][1] );
temp.setSize( 800,750 );
cards.add( ( String ) objetosV[i][0], temp );
public void itemStateChanged(ItemEvent e) {
((CardLayout)cards.getLayout()).show(cards, selector.getSelectedItem().toString() );
Applet tmp = (Applet)cards.getComponent(selector.getSelectedIndex() );
tmp.start();
After i show for second time an Applet and select a button from it. the button does nothing...
Thanks... -
Java Applet Panel problems with CardLayout
Hi, I have a problem a I have been stucked for 2 days.
I created 3 Panels to use with CardLayout. I would switch between those 3 panels depending on user interaction. I have some textfields and text areas on the 2nd and 3rd Panel. On the 1st panel, I would like to use g.drawstring to write some stuff on that panel, but the words would be blocked off if it goes to where the components are on the other panels.

Problem moving through CardLayout
Hi,
I have been unable to find any solid examples of CardLayout, so I have been using some code I found in this forum. I'm getting hung up on how to move forward or backwards through the cards. I know it is myCard.next but for some reason I'm getting hung up on which card I should be referencing and how to associate that card with the code. Perhaps someone could spot the error...
Thanks,

}When importing files Lightroom states:
The following files were not imported because they could not be read.
IMG_5551.CR2
When deleting files in Lightroom it states:
The file named 'IMG_6191.jpg' could not be moved to the Trash folder
When moving files Lightroom shows the following error:
File could not be moved to the selected destination.
EDIT: it is only happening in a single folder/location (with a lot of foto's and subfolders). The rest seems to be working correctly. Strange and irritating. -
Problems with actionListeners on CardLayout...Help Please
I'm having a problem with my clear button on card2 in my code. When pressed it will not clear the data, and I don't see anything wrong with the code. Am I overlooking something? Please take a look at the long code I have posted and let me know what is going on with this if you could.

}You have a generic problem that is illustrated by looking at your 'firstNameField'. You define just one 'firstNameField' variable and then allocated a value several times so that the content of 'firstNameField' add to card2 using
card2.add(firstNameField);
does not refer to the same object as is used in your action listener
firstNameField.setText("");
because in your card3 section you overwrite the original content ot the reference.
You can fix this by sharing a Document e.g.
Document doc = firstNameField.getDocument();
firstNameField = new JTextField(doc, "", 10);
card3.add(firstNameField);
for each time a new field is reqired. -
Does anyone know how/if I should be overriding getLayoutAlignmentX (of LayoutManager2) in order to get the cards (panels) in my CardLayout to appear somewhere other than centred in the panel.
My problem is that I don't seem to be able to alter the layout such that when the card is switched in it appears at the left of the panel in which it is contained.Overriding the layout manager should never be your first step.
All a CardLayout does is make one of its contained panels visible. The layout manager may resize the panel, in which case it's the panel's own layout manager that's centering the content.
The easiest (but ugliest) solution is simply to put another panel in the hierarchy, using FlowLayout. Something like this (uncompiled, untested):
JPanel myCardPanel = new JPanel(new CardLayout());
JPanel holder = new JPanel(new FlowLayout(FlowLayout.LEADING)));
JPanel myRealPanel = // however you get it
holder.add(myRealPanel);
myCardPanel.add(holder, "Top");As I said, this is a really hackish solution. A better solution is to arrange the layout on your real panel so that it can expand without changing the position of its components. Or lock its maximum size ot its preferred size. -
NetBeans IDE 3.6 and CardLayout. Problem in actionPerformed.
I'm trying to make a program that uses a JFrame as TopLevelContainer with CardLayout. The problem is that i dont know how to implement actionPerformed inorder to change between cards(JPanels).
Here is a part of the hole program:
getContentPane().add(jPanel2, "card3");
pack();
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
What should i add in the actionPerformed, inorder to achieve changing between two or more cards(JPanels)?
Note:Every Panel has two navigation buttons.
Here is the hole prog.

Problem with values of some components per card in CardLayout
in card 1 i ask the user to enter the numbers (say the user entered, 55.3,62.5,73.2,86.7)
parsed it, count the observations..
now in card 2, i have a JComboBox of sample sizes from the numbers the user entered. (in the example, the JComboBox should show 1,2,3,4 since the sample size should be from 1 to "n" numbers of observations the user entered)
the problem now is, how can i set the "n" for card 2 where the "n" will come from card 1?
hope i made it clear... please help me...i think i figure it out already...
i put the initiation of card 2 in a different method..
whew! -
Bouncing off the wall: Problems with passing/using pointers to classes
I have a mostly completed "msPaint" (=assigment) program that is driving me nuts!!!
1. First shape you draw doesn't appear.
1.5 Draw a shape by clicking twice on Panel, can change shape, color, fill with what buttons you see.
2. Subsequently only the newest shape appears. Using System.println(); it appears to be drawing as many shapes as it has made, but it doesn't.
3. I owe much to anyone who helps me, here is complete code. Specifically will ask/reward you to reply to a diff link in which I have dukes, got no answer, and can't reallocate dukes. (=5)
Thank you very much.

I like what you've done but (in my humble opinion) it needs a lot of reworking.
Your problem is you're not storing the shapes. You've set up an array but you never assign the shapes to it. I would reccomend using a vector. Heres a quick bit of pseudo code.
Listener class
mouseClicked method
if first click
get mouse x/y
if second click
get mouse x/y
create new MyShape(x1, y1, x2, y2)
call data.addShape(new MyShape)
Data class
constructor
this.myVector = new Vector()
addShape(MyShape shape) method
this.myVector.addElement(shape) -- add new shape
this.myVector.remove(0) -- remove bottom shape
drawAllShapes method
Enumeration enum= this.myVector.elements()
while(enum.hasMoreElements())
MyShape shape = (MyShape)enum.nextElement()
shape.draw()
Feel free to ask any questions.
Rob.
