I am trying to create a JTabbedPane that will always fill the top part of the Component with the tabs. Like so:
And this is how it look now:
And the code for this part:
JTabbedPane tab = new JTabbedPane();
tab.addTab("Items", items);
tab.addTab("Categories", categories);
setContentPane(tab);
//Also tried to create a JTabbedPane class and see if i could remove the labels and manually add two buttons to the top but without success.
I want the tabs to use up as much space as possible without actually shrinking the content of the panels.
So could anyone tell me how to customize the JTabbedPane, the look and feed or just the tabs themselves in order to do that.
The easiest approach is probably to create your own component:
Create a "main" panel that uses a BorderLayout.
Create a panel that uses a GridLayout and add your buttons to this panel. Then add this panel to the "main" panel using BorderLayout.PAGE_START. Each of these button will display a specific panel when clicked.
Create a second panel that uses a CardLayout. Add this panel to the "main" panel using BorderLayout.CENTER. Each of these panels will represent a tab.
The other option is to look at the TabbedPaneUI and find a method that paints each tab and modify the code for your requirement.

I added one jtabbedpane to jframe and the added 3 pannel to jtabbedpane to make 3 tabs. Now i want to add long form in second tab but on running the program whole form is not visible so i am trying to enclose the second panel into JScrollpane but option is not visible it is gray out.
Please help me to solve this problem.
I found the solution
I added one more panel to my second tabb then i raised my all components to that and then i select all the components and enclosed into the JScrollpane
Done thanks...to all for giving your precious time
I need to change the label of the currently selected tab in tabbed pane.
It is for when the user saves the file the change must be reflected in the label of the current panel in the tabbed pane.
Tried a few things like:
tabbedPane.setSelectedComponent(this.panel1.setName(name));
but no good
A very simple line of java code will do this:
tabbedPane.setTitleAt(tabbedPane.getSelectedIndex(), newTabLabel);
This could be easily figured out from the Java API for JTabbedPane.
I Create a frame and in that frame I put one panel n I made a tabbed pane also. I placed 4 icons in the main panel..and I create many panels out side that frame but in the same package. I just want when I click one of the button then it will display the panel out side that class with in the tabbed pane.
Frame
Pakage
Main screen(Where tab pane and buttons are present)
Panel1.java
Panel2.java
Panel3
I just want to know how to call Panel1.java inside tab pane. I am Using NetBean.
If I understand your question correctly, you want to add the panels created in the panel classes to your tabbedPane inside your main class.
You will need to instantiate the Panel1, Panel2 object etc in your pane to then add them, such as:
public static void main(String[] argv){
JTabbedPane tabPane = new JTabbedPane();
tabPane.add(new Panel1());
tabPane.add(new Panel2());
}
But seeing your code would be helpful to fully understand your problem.
EDIT:
To do this in response to a button press, check out this tutorial on Action Listeners:
http://docs.oracle.com/javase/tutorial/uiswing/events/actionlistener.html
I have a JTabbedPane (say myTabPane) having one tab (lets take only one tab for clarity sake). While creating the JTabbedPane, I added a JPanel (say panel_A) to this tab. I have a button on this JPanel. The tab displays my JPanel perfectly with the button on it. So far so good.
I have defined a listener on the button which creates an instance (say panel_B) of another class extending JPanel. This JPanel has got a different set of components on it. I want panel_B to super-impose panel_A. That is, JTabbedPane's tab should show panel_B and hide panel_A.
Please note that I am able to display panel_A OR panel_B when I "bind" the respective panel (one of them) to the tab during creation of the JTabbedPane. However, I want a selective display (or binding, whichever is possible) of only one of the panels with a button-click (ie. at runtime).
How can this be achieved?
Thank you!
This will do what you need:
myTabPane.removeTabAt(0);
myTabPane.addTab("B", panelB);
Please help me create my own custom layout, container, component, layout manager...
Example:
Containers and Layout Managers
Create a window frame.
Nest panels within a frame for better layout control.
Create and display buttons in a panel.
List two component attributes that are controlled by a layout manager.
Set the layout manager for a container.
Place components in a panel using BorderLayout, GridLayout, and FlowLayout.
Name one advantage of each of the layout managers.
Create panels with titles.
i was search on google but can't find any that match my requirement
Thanks for your help
Edit: I was found with keyword "Open Source UI"
Updated: 31, Oct 2016
I would like to updated some information to make it clearly for someone who concern. Back in 6 years ago what i want to know is how to build "UI Framework" from beginning.
If you have interesting like me i would like recommend Android UI Framework is good start because of open source and well document. Enjoy deep dive in to legacy code :) Good luck
Create a window frame
new JFrame();
Nest panels within a frame for better layout control
final JFrame jframe = new JFrame();
final JPanel innerOne = new JPanel();
jframe.add(innerOne);
innerOne.add(otherComponents);
Create and display buttons in a panel
innerOne.add(new JButton("Hello World!"));
List two component attributes that are controlled by a layout manager
Obviously check out JavaDoc of BorderLayout: BorderLayout.NORTH and SOUTH
Set the layout manager for a container
innerOne.setLayout(...);
Place components in a panel using BorderLayout, ...
Just apply the layout, and add providing the arguments for the LayoutManager:
innerOne.setLayout(new BorderLayout());
innerOne.add(..., BorderLayout.NORTH);
Name one advantage of each of the layoutmanager.
Check out the JavaDoc's. They are really helpful in these situations.
Create panels with titles.
innerOne.setBorder(new TitledBorder("Hello World"));
