Bizzare JFileChooser situation, the right click menu text is blank - java

I am using a bare bones JFileChooser on Redhat 6 with the code:
JFileChooser testFileChooser = new JFileChooser("Test");
testFileChooser.showOpenDialog(this);
The JFileChooser works as expected. In the file selection area, if I right click, I get a dialog with three rows, one with an arrow. There is no text describing what the rows does. The first row switches between list and detail views. The second row appears to do nothing and the third row creates a new folder. When I googled about this problem there appears to be no way to access or inspect this right-click popup dialog of the JFileChooser. I do not understand how it could break in the first place like this. I need ideas for how to fix or workaround this problem please.

I've found a fix/workaround!
JFileChooser uses a FilePane internally, which uses the JFileChooser's getComponentPopupMenu as it's context menu. However, because that returns null, it creates its own.
The text on the labels are gotten from the UIManager, with UIManager.getString calls. For some reason, the UIManager is returning empty strings.
So, we just have to set the strings in the UIManager manually.
If you make these calls before creating the file chooser, that'll fix it.
UIManager.put("FileChooser.detailsViewActionLabelText", "Details");
UIManager.put("FileChooser.listViewActionLabelText", "List");
UIManager.put("FileChooser.viewMenuLabelText", "View");
UIManager.put("FileChooser.refreshActionLabelText", "Refresh"));
UIManager.put("FileChooser.newFolderActionLabelText", "New Folder");
I realize this is 4 years late, but I hope this helps.

How can i launch a new pane in java FX immediately to the right of the previous pane within the same window/stage?

My goal is to have a program with 3 panes. A mulitfactor Auth. The first pane will have the user type in a passphrase, while the second pain will allow the user to pick a image from a drop down list. But I want the 3rd pane to launch just to the right of the 2nd pane after the use selects a image in the same "Main" stage.
Not looking for someone to code a program just point me in the right direction to what im trying to do. My searching skills are failing, either im not explaining it right or theres another word for this.
Edit:
This is my idea of how i want it to work. Now that i look at it using a border pane probably makes since, But im still stuck with, How can I launch each section of the border at a different time, i.e when something is clicked.
I would go about it by having 3 panes side by side and just blank for the first FXML file you load in. I would then have another FXML file with the same layout that contains what you want to show up in those panes.
Then with that, you can have the controller on request (like when a user hits submit or however you are wanting these to show up) grab the content inside of the pane on the second FXML file by ID and load it into the pane.
I've done something similar with changing anchor panes and keeping the toolbar from the original so I can add more on this when I get home and should be able to supply some code that is modified to fit your issue.
Edit 1: Sorry I was in a hurry to submit that dive I had to go but I am on mobile now so I can edit but not able to add a lot, just felt I needed to say, there are different options for what you can use to do this which is why I just said a pane instead of anything specific. Just wanted to submit something so you can start looking in the right direction till I am able to update.
Edit 2: Alright now that I am home I tried this out and was able to get this working. Here is how I did it.
So I had two FXML files. One with the 3 areas that you have your items, however, only the box that you want to show when it starts is shown. Each area is enclosed by an AnchorPane. I used the AnchorPane as a container so I can swap out what is inside of it. I then had a second FXML file that had all of the boxes you want to show all of which enclosed in AnchorPanes. Here are pictures explaining what I mean.
I have the first pane named initial.fxml and the second named grabfrom.fxml. For the pane names, I just have it as pane1, pane2, and pane3. Lastly, the methods I have are show2() and show3() and call them from the FXML when the respective buttons are clicked inside of the AnchorePanes.
With initial, I just load that up as normal from the start method in my main class and that is all that is needed to be done with that. We only had it so we could display something that does not have the boxes showing before needed.
Now for the important part
With what I have in show2(), which is called when the button inside of the first pane (which is there from the start) is pressed.
public void show2() throws IOException{
AnchorPane toSetPane2=(AnchorPane) FXMLLoader.load(getClass().getResource("grabfrom.fxml"));
toSetPane2=(AnchorPane) toSetPane2.lookup("#pane2");
pane2.getChildren().setAll(toSetPane2);
}
What this is doing is loading the grabfrom.fxml into a temp var that we cast to an anchor pane. (Do note that this works since as you can see in the screenshot the whole FXML file is an anchor pane. If you're not using it that way you can take out the casting and cast to something you are using or not even cast depending on what it is.)
It then set the var we just made to just the AnchorPane we need, which is the second one since that's the one we are adding. It does this with the .lookup("#ID"); method to get just the pane we need.
Lastly, it sets everything inside of the current pane2 to toSetPane2.
This could all be compressed down into one line, however, I have left it as is for easier reading.
You should be able to use this method of loading in a portion of your application for loading in the third one and for that matter any other parts you want to in any situation.
Edit 3:
Also as #Swatarianess had said, there are stackpanes, this method will work with anything that you can set an ID to so they would work just as well. I used AnchorPanes because I have done a fair bit with them and had some code I could recycle whilst making a test for it so it was easier. All you would do if you were using those though is just cast to a StackPane instead of an AnchorPane like this:
public void show2() throws IOException{
StackPane toSetPane2=(StackPane) FXMLLoader.load(getClass().getResource("grabfrom.fxml"));
toSetPane2=(StackPane) toSetPane2.lookup("#pane2");
pane2.getChildren().setAll(toSetPane2);
}
The transition between panes could be done with a stackpane.

Dynamic Jframe and Jtable

I am coding a small script and stuck on this issue. This is my scripts screenshot.
In ... button it should be automaticly open the browse and the user can select the directory.
In addition If the user click the + Button , the script should create a new path place and the user can select the second path. The problem is how can I add the second or third path place to the gui without damage general view. Like Show Me button has to always seems in gui.
For this problem what is your advice ? Should I use first JScrollPane and then Jtree? or more easy way?
I need your helps and some tricks.
Thanks in advance.

Added tab completion to JFileChooser's File Name inputer

How can I add linux like tab completion to jFileChooser's File Name input field? I'm assuming I need to add a listener to the File Name's text input box to listen for the tab key. But I don't know how to do that. Then once a tab key is hit, I need to look at the directory for files/dir that start with what was inputted. Any ideas on how I can go about doing this?
Emm... I am not pretty sure what the question is but if you want to control is the textfield does contain a file name or something you can simply use JFileChooser as a panel and, as I may remember, there is a way to show/not show its components like "open"/"save"/etc buttons and, of course, replace them with your own; so there should be a way to control its input field I guess. So you need to play around UIManager
For more information you can read this , this and this
If it is not the point... so I still hope you configure your question in a more detailed manner because it is quite unclear :)
Good luck

Dynamically add Textbox to Window when checkbox is checked

I'm just figuring out my way around SWT. I have a little problem that i cant seem to solve. I have a check-box in my window. When the check-box is checked, i would like add a multi-line, read-only, text box below it, lets say 200x200. I want the height of the window to increase to accommodate this text-box. When the check-box is unchecked I'd like the opposite to happen.
Could you help me with this? I can't find an example but maybe I'm not using the right keywords. Cheers.
--EDIT
the.duckman'ss answer was very helpful. I've managed to get it working to some extent. I'm adding a multi-line textbox 480px high. How do I automatically resize the window to accommodate the text box? When the user checks the checkbox, the textbox shows up but the height of the window doesn't increase to accommodate the textbox. My code is a little long so I've put it in PasteBin — http://pastebin.com/01RxKeEr
Thanks.
I recommend looking at the SWT Snippets to every beginner - that's probably the best place to go to with SWT questions.
This snippet does exactly what you want.
Edit
Ooops, I ignored the second half of your question, sorry. Simply add this line to your listener:
shell.setSize(shell.computeSize(SWT.DEFAULT, SWT.DEFAULT));

How can I create an AutoComplete popup in a JTextPane in Java?

I am creating a SQL editor. I am using JTextPane for the editor. I want to implement AutoCompletion for table name etc. like Eclipse.
I think the appropriate class for displaying info on top of another component is JPopupMenu, which already handles layering correctly to display itself. JPopupMenu has a show() method that takes its 'parent' component as an argument, and it will show itself in that component's coordinate space. Since you want to display a selection of terms for the user to choose from, a menu seems appropriate.
To check for text changes, you'd add a DocumentListener to the document that's wrapped by the JTextPane; you can access it using getDocument().
To find out where the cursor (actually, the caret) is, you can use getCaretPosition(). That returns the caret's position within the text stream as an int. You can use modelToView() to translate that position to actual (x,y) coordinates. That in turn will tell you where to show your menu.
You can use addKeyListener() to catch keyboard events on your JTextPane, like hitting Ctrl-Space.
The combination of all that should allow you to do what you're looking to do.
You can also use http://fifesoft.com/autocomplete/. You can install it on any JTextComponent.
For things like this you probably should consider layered panes so your auto-complete suggestions appear in the correct place and z-order.
Furthermore you will have to look for changes in the JTextPane to know when the user is typing and you will need a parser that understands what is typed so you can offer the feature only at appropriate points.
It's not quite clear what exactly your problem is and what you got so far.
I achieved this by adding a key listener to the JTextPane and checking for CTRL + Space keystrokes. When the appropriate key combo was detected the listener went off and looked up the list of possible matches based on the characters directly to the left of the cursor at the time of the key press and found the best matches and displayed them to the user in a JPopup. If there was an exact match then it simply replaced the partial text with the match. If no matches were found an option was given to the user to add the text that they had already typed, edit it and record it into the list of acceptable data.
We use jide. They have a lot of components that help you do this kind of thing really easily
