I had just a few class of java on college, but I want to do a thing that I don't know how.
Is basically a window with a SplitPane, on Left side I have a menu made with toggle buttons, and on the Right side I need to change the content based on each button.
Theres any way to design the ViewA and ViewB on separated JFrame Form and load then inside my Right Side when I click on menu items?
Another idea is, put the ViewA and ViewB put a JTabbedPane on the Right Side, and hide the Tabs. So there's any way to hide the tabs?
I have none experience developing in java, any problem about this concept (difficult, loading time, memory, maintenance), If you guy know a better way to to this, I just don't want a lot of windows popping up.
A really simply way would be to simply have a set of jPanels in the right side, with only one ever set to Visible.
Basically, for each toggle on the left side, you will have an Event Listener that does this:
private void toggle1ActionPerformed(java.awt.event.ActionEvent evt) {
jPanel1.setVisible(false);
jPanel2.setVisible(false);
jPanel3.setVisible(true);
}
Simply changing the true value depending on the individual toggle.
In Netbeans, if using the GUI editor, you can simply double click the toggle button to generate the listener and appropriate method, then fill in the code for it.

I am making project with GUI. The thing is, that I have a button and what I need to do is that after clicking this button I need to change Frame layout. For example, like when you are installing some program and you click "next" button, the Frame layout changes and you can see some different content. Basicly, dynamic wizard.
I have tried use another Frame, but it opens in another window and that is not what I want. I want to open it in the same window.
Another thing I have tried is set visibility of these components I don't want to be displayed to false, but I find it unprofessional and it is overlook in making a desing, when I have components over themselfs.
So do you guys have any idea? Thank you.
Most of the times for a wizard like GUI, you should have JFrame and a set of JPanels. In each step you can pass the shared data as constructor arguments to each panel, and when you are making one of them invisible and make another one visible, you can get some date from the previous step panel and pass it to the next step panel(if needed).
It is very common that your panels extend the JPanel and have some argument in their constructor(s). You use these data for initializing your panel and managing the state of the overall progress.
There is no a total plan for all situations. So you should decide what to do which is best fit for your case.
Try not to have multiple JFrames.
Hope this would be helpful.
I am creating a GUI for my project. I am completely stuck at one point. I was able to create a GUI which will make some simple queries like the release number, command name, and few other boolean questions.
Now I want the user to press CONTINUE button to move to the next page of the GUI form. I have created the continue button, but now I need to register an event to it. This is where I am stuck. I have no idea what event can I register to it which will move the GUI to next page. (By moving to the next page I mean, the different GUI pages we see when we are installing a software for our computer.)
For instance, if I am installing iTunes, I'd first select the radio button for "I accept the terms and conditions" and then I'd press the CONTINUE or the NEXT button to move ahead. If I need to come back, I'd press the BACK button.
One logical answer would be to create another GUI form and then link it to the one I created first.
EDIT:: this is the first time I am working in Java, so I might have ignored some obvious facts.
Look into using a CardLayout, adding several JPanels to the CardLayout-using container, and then to swap to the next view (the next JPanel), call the layout's next(...) method in the JButton's ActionListener. You could also randomly access components held by the CardLayout using its show(...) method.
To learn more about this including sample code, please have a look at the CardLayout Tutorial, and the API.
Well, register an ActionListener or an Action with the button. To do that wizard style, have a look at the CardLayout layout manager to switch cards or use a tabbed pane, hide the tabs and switch them inside the action or action listener.
if i understood, i think you should use the CardLayout
If you are using Swing, you can using several instances of JPanel over a one instance of JFrame.
You can have something like that structure:
JFrame
+------JPanel:root
|
+---JPanel:current // This panel change by other instance
|
+---JPanel:controlPanel // This panel contains you button
In you button need add a ActionListener with the method addActionListener
The panel control may need changes your elements, may the text of button or remove the listener and change by other.
I hope that can help
I'd like to create a set of buttons in a Java Swing application like you get in a typical tool palette in a paint program. That is, a set of small square buttons, each containing an icon, only one of which is pressed down, and when you press another button, the first is deselected. I've thought of a number of solutions and none of them seem very easy/elegant.
This sounds like a job for JRadioButton, but if you add an Icon to that, you still get the small circle, which is fairly space inefficient. I guess an option would be finding an alternative Look and Feel or painting code for JRadioButton.
Another alternative might be to add JButton to a ButtonGroup, maybe setting a JToggleButton.ToggleButtonModel as the model, but that doesn't have the desired effect, as the painting code for a standard JButton does not keep it depressed when selected. Possibly the JButton code could be modified to do this. Like making it painting "selected" the same way as "pressed".
A third alternative would be to use normal JButton's, and add a common mouse listener that keeps them pressed or not, and communicates the changes between the buttons.
Can anyone advise on the best way to achieve the aim please? A simple method I've missed would be best, but advice on which of these three alternatives would be best and pointers on how to get started would be useful too.
What about a plain JToggleButton in a ButtonGroup? It is not abstract, you can instantiate one with an Icon, and it stays depressed while selected.
See the SwingSet2 demo:
http://java.sun.com/products/plugin/1.4/demos/jfc/SwingSet2/SwingSet2.html
Click the second icon on the toolbar (the one twith the check box and radio button) then tab "Radio buttons". Then click on "Paint Border" on the right panel, under "Display Options".
Source code of the demo is under your JDK install dir, so for example on my PC it's under \jdk1.6.0_01\demo\jfc\SwingSet2\src
I am programming a GUI application in Java. I do it for the first time.
I would like to have a form (with radio buttons and so on). After the form is filled in and the "Submit" button is pressed I would like to have a new window. I see two potential ways to do it:
Close the "old" window and open a "new" one.
Remove "old" elements from the existing window and put there "new" elements.
What is the standard way to go? If it is the first way, what is the command to close the window? If it is the second one, how can I remove elements from the existing window?
What you should do is create new JPanel for all the windows you want to show, then remove (or hide) the panel you want to hide and add or show the one you want to show.
I don't know too much about Java so I can't answer to your specific questions, but I want to remind you of the window opening/closing effect since Windows Vista: It looks kind of weird in some older setup wizards where everytime you click next the window fades out and in...
I think the most logical way is to have 2 objects("Close the "old" window and open a "new" one")
Anyway, I suggest you make an abstract class with the common elements, and then extend it with Window1 and Window2.
Java frames are destroyed with the dispose() method.
I am developing a desktop Java application with GUI implemented through Swing. I have made a JFrame and have added three buttons on it - Add, Edit, Delete.
Now I want that whenever a user clicks on any of the button, the content specific to that button appears besides those three buttons.
So how to implement this? Should I need to add a JPanel besides those three buttons and then add the content specific to the button to that JPanel?
So far, I have taken a JFrame and have added 3 buttons on it. That's it.
For the Add button, I want to add some buttons and textfields to add information to the database.
For the Delete button, I want to add some buttons to find records in the database based on the information entered through the user in the textfield that appears when the user clicks on the Delete button.
Similar type of content for Edit button.
So how to implement this. Should I need to add a JPanel besides those three buttons and then add the content specific to the button to that JPane
That would be fine. When you push the button, you can call JPanel.removeAll() to remove all the controls currently in the control, and then just do the layout again, specific to whatever button you pushed.
If you have custom swing controls, just add your custom control the JPanel using a BorderLayout and putting in the center.
Another option would be to use a CardLayout, and flipping between the cards when a user presses one of the buttons. If the layouts for the buttons never change, that would probably be a better way to do it. Obviously if the content changes between button presses, you'll need to redo the layout each time.
Either of Chad's or Alex's answers would be fine. You will probably need to call a combination of revalidate() and repaint() on the panel that you've changed, as in the past I've noticed Swing doesn't always like panels being swapped out.
Also, have you considered using a JTabbedPane instead of manually coding the interaction with the add/edit/delete buttons?
I haven't done a lot of Java programming, but I think using 2-3 different JPanel, and make visible the one you need depending on the button that was clicked would do the trick.
I'm not sure if this is the right approach though.
I was using a JFrame to add all buttons and make a new JFrame for a new window and hide a previous one.
gven way are better. I will do that now.
