Button in JTabbedPane tab

Greetings,
i'd like to have a button on every tab in JTabbedPane, like close button in NetBeans when you edit the code. By default, you can put an icon only. Do you guys know how to do that?
thanks in advence.

If you can wait another couple of months (or if you are willing to use the beta version), you can use the new JTabbedPane features in Java 6 (Mustang). Have a look at the method setTabComponentAt:

Add button to JTabbedPane to add new tab

Does anyone know how to add a JButton to a JTabbed pane (in the tab bar) so that it is always at the end of all the tabs and when it is clicked it will add a new tab into the tabbed pane.
The functionallity I am looking for is the same as that provided by the button in the tab bar for Firefox and Internet Explorer.

Along the line of what TBM was saying:

JTabbedPane with one close button for all tabs

Hello,
there have several solutions been posted for JTabbedPane subclasses that provide tabs with icons working as close buttons on each tab. I think this is not user friendly because the user can hit the close button accidentally when selecting a tab. And a "really close?" dialog is clumsy.
Therefore I prefer the Netscape browser style: There's only one close button rightmost of the tabs that closes the selected tab. But I don't have an idea how to achieve this.
Does anyone have a solution or an idea? Thanks in advance for help.

This solution has been posted several times and is not what I wanted. But I rewrote the thing so that
- the close buttons are on the right hand side of each tab so that it is conformant with Eclipse style, and
- the close buttons work only with a left click (see code below).
I just wonder how I can move the text a little bit to the left so that the appearence is a bit more balanced. Can someone help, please?

Putting a button on a tab like in netbeans

In netbeans, the tabbed panes have buttons on the tabs so that you can close a file right there.
Does anyone know how to do this?
Thanks,

This question has been asked a lot, and I know I saw a handy solution posted recently - you might try a search on this forum. Inspired by the solution I found, I came up with an implementation that allows you to add an Action (which provides the icon and the behavior) to a JTabbedPane tab. It is an extension of JTabbedPane along with an Icon that presents buttons for the added Actions. It could use a little work, but here's the code:
//     ActionableTabbedPane.java
//     A JTabbedPane that supports an ActionTabIcon.

How to point to another tab on click of a button in another tab?

Hi all,
I am creating an application in which I am using Tabbar and then referring separate canvas for each tab using viewstack.Now I have a button in in one tab and on click of the button i need to open another tab.For reusability i have created separate mxml for each functionality of subtabs.Please help me on how to link the click of button in one tab screen to another tab.
Thanks in advance.

I would suggest creating a custom event that contains the index of the tab (viewstack child) you are wanting to move too. The button would dispatch the event and the tab navigator would require an eventListener to listen for the event type. The handler for the eventListner would then take the index passed and make the change myViewStack.selectedIndex=2 (or whatever the custom event contained)
Note: you could also pass the name of the tab you were wanting to move to and set it that way.
-Joe

When I attempt to open a new tab by clicking the "new tab" button on the tabs bar, the tab will not open. Can this be fixed and how?

When I open my Firefox browser, the normal 1 tab comes up. But when I attempt to open new tabs with the "new tabs" button, a new tab will not open. I have also tried right-clicking on the tabs toolbar but tabs will not open. The only way I can get a new tab to open is by right-clicking on a link and selecting the "open new tab" option in the right-click menu.

The Ask Toolbar is causing that in the Firefox 3.6.13 version. Disable that extension or un-install it.

In FF 7.0.1, the New Tab button on the Tab Strip disappeared after clicking the Tab Group icon and trying to return, so I'm looking for advice on how to get the New Tab to reappear on the Tab Strip.

In Windows Vista, FF 7.0.1, I selected the Tab Group button to try it out. However, when I selected the Tab Group button again to close that view, the New Tab button in the Tab Strip no longer appears. I'm requesting help to restore the New Tab button (has the "+" sign on it) on the Tab Strip just to the right of the currently open tabs.

You can find the New Tab button showing as a '+' on the Tab bar.
You can open the Customize window and drag the New Tab button that shows as a plus sign (+) from the Tab bar on another toolbar and it will become a regular toolbar button like the New Tab button that you have in Firefox 3 versions.<br />
Open the Customize window via "View > Toolbars > Customize" or via "Firefox > Options > Toolbar Layout"
If you can't find the New Tab button then click the "Restore Default Set" button in the Customize window.
If you want the New Tab button at the far right end of the Tab bar then place a flexible space to the left of it.

When I click on the new tab button, a new tab does not open or when I go to file new tab a new tab will not open either.

When I click on the new tab button, a new tab does not open or when I go to file new tab a new tab will not open either.

Un-install the '''''Ask Toolbar''''' until Ask fixes the problem caused by their toolbar.

How do i add "open a new tab" button back to tabs & bookmarks back to the menu bar? i was able to click & drag bookmarks there and the tab button was always thr

how do i add the "open a new tab" plus sign button, back to tabs & bookmarks back to the menu bar? i was able to click & drag bookmarks and folders containing bookmarks from the bookmark menu to a toolbar and the tab + button was always on the right side of a tab before i saw ff 13.0.1 on windows 7.
areas i need back, have red around 'em

Somehow your bookmarks that normally appear on the separate Bookmarks Toolbar (the part on the left) got onto your main Navigation Toolbar. To move them back, return to Customize mode and drag "Bookmarks Toolbar Items" to the Bookmarks Toolbar. Then click Done and hopefully that will stick.

Is there any add on which i can reload all tabs from offline mode to online immediately without press the resend button in each tab?

Hello to everyone!
I want to ask if there is any add on to firefox which I can reload all tabs from offline mode to online mode immediately without press the resend button for each tab all the time.

is it illegal to record a conversation without the other caller knowing?
That depends on where you are... In the state of New Jersey, where I live, I believe that it is legal to record a conversation if at least one party to that conversation knows that it is being recorded, and there is no legal duty to inform the other party that the conversation is being recorded.
This means that I could legally record all conversations I have with other people within the state of NJ, and likewise anybody whom I call or who calls me can record out conversations. However, it would be illegal for a third party to record out conversation without our knowledge and consent.
Now the situation becomes more complex if I call somebody, or somebody calls me, across state lines... I've not made a study of the laws in every state, but I would not be surprised if there are states where both parties must give consent for the conversation to be recorded. This is probably the reason for the announcement "your call may be monitored and recorded for quality purposes" at the beginning of every call to customer support...
Wikipedia has a useful introductory article, and a quick Google search turns up much more information.

Using Firefox 26. How do I get a close button for each tab at the top of the screen?

Some time ago, I had a close tab button for each tab on the top of the screen. I want that back. I have no additional add ons and the close tab is set to 1. Changing it to 2 does nothing.

Do you have installed this extension?
*Firefox/Tools > Add-ons > Extensions
If you do not have the extension and also have no need for the feature that it provides then you can ignore this.
If it works in Safe Mode and in normal mode with all extensions (Firefox/Tools > Add-ons > Extensions) disabled then try to find which extension is causing it by enabling one extension at a time until the problem reappears.
Close and restart Firefox after each change via "Firefox > Exit" (Windows: Firefox/File > Exit; Mac: Firefox > Quit Firefox; Linux: Firefox/File > Quit)
You can use one of these to start Firefox in <u>Safe Mode</u>:
*On Windows, hold down the Shift key while starting Firefox with a double-click on the Firefox desktop shortcut
*On Mac, hold down the Options key while starting Firefox
*Help > Restart with Add-ons Disabled

Pressed "start transformation" button in test tab

I created Data Type/Message Type/Message Interfaces/Interface mappings/Message Mappings for source/target system.
when I pressed "start transformation" button in test tab in message mappings, I get a error:
Mapping object MM_xxx incomplete. Unable to continue execution
structure with min!=max without mapping
Please help me,many thanks

Mikenl,
Usually this type of error comes when the mapping is not properly done . and Mandatory target fields are not mapped .
there are plenty of threads in SDN with the similar problem . Kindly go thorugh them .

Object Status button in Status tab of Item

Hi All
How can i configure to see Object status button in Status tab of item in the Sales order data.
Please list down the steps.
Right now i dont have Object status button.
Thanks in advance
Sonali

Dear Sonali
Create a Profile in BS02, maintain the required controls there and save. Now go to VOV8, select your sale order type and execute. There you can see the field "Status profile" under the tab "Transaction flow". Assign the profile here and save.
Now create a sale order and check whether you could see the status profile.
thanks
