JTextPane inside JScrollPane
Hi,
I've seen a lot of possibilities to get a JTextPane into JScrollPane without wraping the text in the forum. None worked for me..
My situation:
JTextPane(editable=false) with given text(DefaultStyledDocument) is inside JScrollPane.
I replace (by pressing a button) some text parts with longer text AND JTextPane wraps it!..
I tried to set the size of the textPane to the computed line width of the longst line, but nothing happened.. (I expected the JScrollPane to show off horizontal scrollbar, because the width of JTextPane is getting bigger than the width of JScrollPane).
Anyone knows how to put formatted text into text- or scrollpane without wraping it?
And who allowed JTextPane to wrap my lines anyway?!
(it's called StyledDocument and not ChaosDocument :)
Thanks in advance!
Raman.
Not sure that JTextPane is the best place to start. The wrapping is controlled by ParagraphView and its underlying structure. Try looking at implementing extensions to the standard EditorKit/ViewFactory to tweak this behaviour

JTextPane inside JScrollPane resizing when updated
Hiya all,
I've been struggling with this problem and checking the forums, but didn't find a solution, so I hope someone can help...at least help me for the nice picture :) It has to do with JTextPane's automatically resizing to their content on a GUI update, rather than scrollbars appearing (the desired result).
Basically, I have a scenario where I am creating a series of multiple choice answers for a question. Each answer consists of a JTextPane inside a JScrollPane, and a JRadioButton, which are all contained in a JPanel (called singleAnswerPanel). So for 2 answers, I would have 2 of these singleAnswerPanels. There is a one large JPanel that contains all the singleAnswerPanels (called allAnswersPanel). This allAnswersPanel is contained in a JScrollPane. Graphically, this looks like:
| JPanel (allAnswersPanel) inside a JScrollPane |
| |
| ------------------------------------------------------------ |
| | JPanel (singleAnswerPanel) | |
| | ---------------------------------- | |
| | | JTextPane inside a JScrollPane | * JRadioButton | |
| | ---------------------------------- | |
| | | |
| ------------------------------------------------------------ |
| |
| |
| ------------------------------------------------------------ |
| | JPanel (singleAnswerPanel) | |
| | ---------------------------------- | |
| | | JTextPane inside a JScrollPane | * JRadioButton | |
| | ---------------------------------- | |
| | | |
| ------------------------------------------------------------ |
| |
----------------------------------------------------------------So above, I show 2 answers that can be filled in with text. So assuming both answer JTextPanes are filled with text beyond their current border (scrollbars appear as expected) and the user wishes to add more answers. I have a button to add another singleAnswerPanel to the containing JPanel (allAnswersPanel), and then I validate the main JScrollPane that contains the allAnswersPanel as it's view. The problem that occurs is the existing single answer JTextPanes resize to the size of their text and the vertical scrollbars (only vertical ones setup) of the JTextPanes dissappear! My intent is to keep the existing JScrollPanes the same size (with their scrollbars) when a new answer is added.
The code snippet below shows what gets done when a new answer is added:
private void createAnswer()
// The panel that will hold the new single answer JTextPane pane
// (inside a JScrollPane) and radio button.
JPanel singleAnswerPanel = new JPanel();
// Create the text pane for the single answer.
JTextPane singleAnswerTextPane = new JTextPane();
Dimension dimensions = new Dimension(200, 30);
singleAnswerTextPane.setPreferredSize(dimensions);
singleAnswerTextPane.setMaximumSize(dimensions);
// Create a scroll pane and add the single answer text pane.
JScrollPane singleAnswerScrollPane =
new JScrollPane(singleAnswerTextPane);
// Create a radio button that is associated with the single
// answer text pane above.
JRadioButton singleAnswerRadioButton = new JRadioButton();
// Add the scroll pane and radio button to the panel (for a single
// answer).
singleAnswerPanel.add(singleAnswerScrollPane);
singleAnswerPanel.add(singleAnswerRadioButton);
// Add the panel holding a single answer to the panel holding
// all the answers.
m_allAnswersPanel.add(singleAnswerPanel);
// Update the display. m_allAnswersScrollPane is a JScrollPane
// that has the m_allAnswersPanel (JPanel) as its view.
m_allAnswersScrollPane.validate();
} Sorry for the length of the message, but I really want to solve this problem. So again, when updating the JScrollPane with validate(), the JTextPane for a single answer resizes to it's contents (plain text currently) and loses it's vertical scrollbars, but I want it to stay the same size and maintain the scrollbars.

Trouble Scrolling down(JTextPane inside JScrollPane)
I am writting a java interface to the Jabber IM system. I'm trying to allow html in the messages, so I have a JTextPane that I use to show what has been said. In order to scroll, I've placed the JTextPane within a JScrollPane. When a new message needs to be placed into the JTextPane, I set the JTextPane to the proper text and set the scroll bar from the scroll pane to it's .getMaximum() value. My problem is that the .getMaximum() function only gets the NEW, ACTUAL maximum AFTER the JTextPane has been parsed and painted into the JPanel. The time it takes to do this is proportional to the length of the text within the JText pane and relative to the speed of the computer. So, the scroll bars should be done in response to the completion of the painting of the JTextPane instead of a set time delay. I don't know how to do this. I assume I need to overwrite some paint or repaint function, but I don't know which one to overwrite. The JTextPane is in a JScrollPane in a JSplitPane in a JPanel in a JFrame, if that helps at all.
I've been stuck on this forever..
Thanks for any help.Gave you 6 $. JTextPane doesn't have the insert function, so I've been using setText(). The problem is that the second the Pane is redrawn, it shows the top of the document, then scrolls to the bottom. This takes a fraction of a second, but still is undesireable.
What I'm trying to do is make a new textpane object, set the text, set the caret position, THEN replace the old pane. The problem is, I can't just use oldPane = newPane because that just makes oldPane reference the new Object.(The object shown is then only referenced from the parent swing component, a JScrollPane) I've tried using the .setViewportView on the JScrollPane that the JTextPane is within, but then it doesn't scroll to the caret position.
I've gotten it to work once. I had created all new objects(JTextPane within JScrollPane within JSplitPane within JPanel) adding each to it's parent and adding the JPanel to the container. This worked ONCE! I changed the code, then changed it back and it didn't work again...
Here's the code I have for buffering the JTextPane.
if(chatPane == chatPaneBuffer2){
chatPaneBuffer1.setText(chatStringBuffer.toString());
chatPaneBuffer1.setCaretPosition(chatPaneBuffer1.getDocument().getLength());
chatPane = chatPaneBuffer1;
}else{
chatPaneBuffer2.setText(chatStringBuffer.toString());
chatPaneBuffer2.setCaretPosition(chatPaneBuffer2.getDocument().getLength());
chatPane = chatPaneBuffer2;
This works, but somehow I need the object chatPane is pointing at to be referenced by my JScrollPane. -
JTextPane inside a JScrollPane: any way to display a certain section?
I have a GUI with a JTextPane inside a JScrollPane.
The text of the JTextPane is the contents of a text file, so it typically has many lines.
I want the JScrollPane (whose preferred size has already been previously set to display 11 rows of text) to always show one target line as the middle row, and the 5 rows before and after it as the remaining 10 rows.
In other words, I want to show a certain line and its surrounding context.
Do you guys know how to achieve this? I have already tried calling
JTextPane.setCaretPositionbut this is inadequate because it merely guarantees that the line with the caret is visible--but it does not guarantee to center the caret line in the middle of the JScrollPane.
I also tried calling
textPane.scrollRectToVisible( textPane.modelToView(caretPos) );where textPane is my JTextPane, but this failed completely (seems to always display the final lines of the file).
Anyone have any suggestions?Daryl: thanks for your response.
My original code looked like this:
int caretPos = 0;
for (int i = 0; i <= index; i++) {
caretPos += lines.length();
textPane.setCaretPosition(caretPos);
With *just* the above, you get the behavior that I originally described, namely, the line in question (which is lines[index]) always gets displayed, but it is not necessarily in the middle of the JScrollPane.
I tried commenting out the line above which calls setCaretPosition, and used essentially your code instead:Rectangle caretRectangle = textPane.modelToView(caretPos);
Rectangle viewRectangle = new Rectangle(
0, caretRectangle.y - (scrollPane.getHeight() - caretRectangle.height) / 2,
scrollPane.getWidth(), scrollPane.getHeight()
textPane.scrollRectToVisible(viewRectangle);This fails too: the JScrollPane now always shows the bottom of the JTextPane.
What does work is to use *both* techniques, namely, call setCaretPosition as well as scrollRectToVisible: // set the caret to the line in question (i.e. at index); this merely guarantees that this line is visible, but not necessarily centered
int caretPos = 0;
for (int i = 0; i <= index; i++) {
caretPos += lines[i].length();
textPane.setCaretPosition(caretPos);
// and IN ADDITION cause scrollPane's viewport to be centered around the line
Rectangle caretRectangle = textPane.modelToView(caretPos);
Rectangle viewRectangle = new Rectangle(
0, caretRectangle.y - (scrollPane.getHeight() - caretRectangle.height) / 2,
scrollPane.getWidth(), scrollPane.getHeight()
textPane.scrollRectToVisible(viewRectangle);The interesting question is why do you need to do both steps?
I think that I know the reason, but I would love to see someone confirm or deny this. What follows is my speculation.
The above code is inside a method that is call by a run method of the class in question which is always executed by the event dispatch thread (EDT), so it is not an illegal thread use case. However, in the method that has the code above, I am clearing all existing text of the JTextPane and then repopulating it (with that String[] lines used above, which came from parsing a file).
Now, in [this posting|http://forums.sun.com/thread.jspa?messageID=10289999#10289999], camickr claimed:
"When text is inserted into a Document, behind the scenes a call to setCaretPosition() is made to position the caret after the newly inserted text. However inserting text into a document is a complex procedure since Elements need to be created as the text inserted into the Document is parsed. So the call to the setCaretPosition() method is placed in a SwingUtilities.invokeLater(), which means tha code gets added to the end of the GUI EDT to be executed once the Document is in a complete state. So basically what is happening is that your call to set the view position does execute, but then is gets overridden by the setCaretPosition() method call."
If the above claim is true, then all the calls in that method to add the file's text result in implicit calls to setCaretPosition which will be executed AFTER the method above ends (i.e. asynchronously, later on by the event dispatch thread). Hence, I need to do an explicit setCaretPosition call of my own to override these implicit calls.
Now, I am not sure that I totally buy this explanation. I would like to see more proof of camickr's claims for one: I did a quick code review of some of the classes involved, and do not see where calling AbstractDocument.insertString generates an implicit call to setCaretPosition on the EDT. To be sure, the code is complex, and I do not know where exactly to look, and maybe this is done by some listener or something, who knows. Furthermore, my explicit call to setCaretPosition is done synchronously on the EDT (recall: that method above in my class is called by its run which is executed by the EDT). So, my explicit call to setCaretPosition should occur in time before all of those delayed implicit calls, and thus should actually be overridden by them, no?
I would love to hear from someone who really knows Swing... -

}hi sir ,
thaks for u'r suggession.Its working fine but the
properties of the previous tree were not working
after setModel() property .like action at leaf node
is not working,I'm sorry but I don't understand. I think you are saying that the problem is solved but I can read it to mean that you still have a problem.
If you still have a problem then please post some code (using the [code] tags of course). -
Install Application - TextArea inside JScrollPane
I've been working on an install application to install another one of my programs (next/accept/next/ finish type of thing) and had a couple questions and would appreciate any help anyone can give.
Some Background info:
I made images and have them display as image icons through jlabels for the buttons and background. The labels have classes applying various mouselisteners (Mousepressed, MouseEntered, MouseExited, etc) changing the images and moving from screen to screen. I have my layout set to null, not for any particular reason, but because I have no formal education in layout managers.
1) Is there a conical solution to moving through various windows? That is, right now I move through the various 'screens' with a check on an int called state, that gets incremented and decremented through forward and back buttons. I looked at some code given to us on a test by our teacher (we had to find bugs) and saw that he had implemented a fake "state" interface, with constants like "Account_State" to control where you were in the program. This seems a bit easier to read than ints, but is there a correct built in version of his states?
2) On the second screen I have a license agreement (actually required for the application that gets installed), and a checkbox. The license is held inside of a JTextArea(scroll) inside a JScrollPane(textscroll). The JScrollPane is extending in weird ways. The following is a stripped down version of my code (it runs and demonstrates the problem):

}Sorry about all the text for the agreement. I've tried a number of different things I got from searching the forums at different points in the code (setting the number of rows/columns, setting max and min sizes, etc etc) The code above that wraps the text I could have sworn I tried 3 times before it magically worked... I also tried using the awt component for textareas that had the scrollbars built in, but scrapped it after having even more difficulties with that one. I'm trying to get the textbox to only go down about 300 px and 300 px to the right. Using the graphical editor to change it produces a null pointer error at compile time(?!?). Can anyone help me to get the textbox to render as I want it to?

Obnoxious JTextPane and JScrollPane problem.
I have written a Tailing program. All works great except for one really annoying issue with my JScollPane. I will do my best to explain the problem:
The program will continue tailing a file and adding the text to the JTextPane. When a user scrolls up on the JScrollPane, the program still adds the text to the bottom of the JTextPane and the user can continue to view what they need.
Here is the problem: I have text being colored throughout the text pane. For instance, the word ERROR will be in red. The problem is when the program colors the text, it moves the scroll pane to the line where word that was colored is at. I don't want that. If the user moves the scroll bar, I want the scroll bar to always stay there. I don't want the program to move to the text that was just colored.
Is there a way to turn that off? I can't find anything like that anywhere.Coloring text will not cause the scrollpane to scroll.
You must be playing with the caret position or something.
If you need further help then you need to create a [url http://homepage1.nifty.com/algafield/sscce.html]Short, Self Contained, Compilable and Executable, Example Program (SSCCE) that demonstrates the incorrect behaviour, because I can't guess exactly what you are doing based on the information provided.

JList(Vector) inside JScrollPane vanishes!
Hi all, I have a problem thats driving me crazy, Im really stumped on this one;
Im trying to update the GUI on a packet sniffer I wrote a while ago,
I have a GUI class below as part of a larger program, this class containes a JList(Vector) inside a JScrollPane inside a JPanel inside a JFrame, I want this JList to be on the screen all the time, and grow dynamically as new elements are added to the Vector.
Elements are added via an accessor method addPacket(Capture), you can assume the other classes in my program work fine.
The problem is, the JFrame periodically goes blank, sometimes the scrollbars are present, sometimes not. After a while (sometimes) the JList reappears, containing the list of packets as it should, but it never lasts very long. Often it will disappear permanently.
The class below is pretty short and simple, I really hope this is a simple and obvious mistake Ive made that someone can spot.
Thanks,
Soothsayer

JTextPane in JScrollPane... Scrolling when needed
Hello all.
I have a jtextpane in a jscrollpane and I'm using the following code to append a line in jtextpane and set the vertical scrollbar of jscrollpane at the bottom...
htmlDoc = (HTMLDocument) output.getDocument();
htmlKit.insertHTML(htmlDoc, htmlDoc.getLength(), s, 0, 0, null);
output.setCaretPosition(htmlDoc.getLength());where output is the jtextpane.
My problem is that, if the user manually changes the position of the vertical scrollbar, after appending a new line in jtextpane, the above code will set the scrollbar at the bottom.
Is it possible to keep the scrollbar at the position it was before the new line has been appended (if the position of the scrollbar has been changed)?
Thanks in advance,
CharalamposStanislavL... with your suggestion the scroll bar will never scroll to the bottom.
I want to place the scroll bar at the bottom if it was at the bottom before I append text to jtextpane, otherwise I want to leave the scroll bar at the same position it was before I append the text. -
Problem about using JTextPane in JScrollPane
I put a JTextPane in a JScrollPane.
But when I reduce the window size of the JScrollPane with my mouse, the text line in the JTextPane is broken to newlines automatically due to the reduced window size.
How to prevent the text lines breaking in this situation!OK, so the words are wrapping when they're not suppose to. How are you adding your JTextPane to the JScrollpane? Also, does setting a preferred size or a minimum size on the JTextPane help?
That's an odd problem. In looking at the API I see that JTextArea and JTextPane are both derived (eventually) from JTextComponent. But the line wrap option is only in JTextArea. This makes me think that it would be possible to overload paint method of the JTextPane. But wow! That would be messy.
I'll keep thinking about it. Let us know if you find a solution. -

Drag/drop into JTable inside JScrollPane
Hello,
I have a table inside a JScrollPane. I can set the table as the DropTarget by the command:
new DropTarget(table,fileDropTargetListener);
but I cannot set the JScrollPane be the DropTarget by the same command.
the problem is that: I cannot set the table to fit the JScrollPane by the command setsize(scrollPane.getSize() ), setPreferedSize(scrollPane.getPreferedSize()), (don't know for what reason, they don't work to fit the scrollpane), therefore when user drags an item to the JScrollPane but outside the table, the drag gesture doesnot display.
Please anyone help me how to solve this problem. Thank you,
fantabkYes, I use custom cell renderer and cell editor for ParentTable, which returns NestedTable.
DnD turned on for the ParentTable, so when the NestedTable is active (some cells selected in it) it receives DnD events, which are turned off for it, and DnD doesn't work.
Possible solution is to turn DnD for NestedTable (not for ParentTable), and i'll do this if it is impossible to make it work in current configuration.
So the question is � is this possible do not pass DnD event to NestedTable ? -
FlowLayout fails to wrap inside JScrollPane
I have a JPanel with FlowLayout inside a JScrollPane with the horizontal scrollbar disabled. I expect the FlowLayout to wrap the buttons in the example below but it doesn't.
Could someone plase confirm this as a Swing bugg and perhaps suggest a workaround.
Many Thanks!

}I think the policies controll whether the scrollbars are shown and not whether the JScrollPane is "scrollable". It's still a JScrollPane, whether you choose to display the scrollbars. If you don't want scrolling, I suggest useing a different component.
I could be wrong on this. Someone please chime in if you disagree. -
JLayeredPane inside JScrollPane - please help!!
Hi everyone!
i'm having the following problem: I need to add a JLayeredPane to a JScrollPane. this JLayeredPane contains a JGraph and this is what I'm doing:
jlayeredPane = new JLayeredPane();
jlayeredPane.add(graph, JLayeredPane.DEFAULT_LAYER);
jlayeredPane.setPreferredSize(new Dimension(1000,1000));
jlayeredPane.setMinimumSize(new Dimension(1000,1000));
jsp = new JScrollPane(jlayeredPane);
add(jsp);
[/code
but the graph doesn't show up at all. can anyone help me please. i have a deadline today and really need to figure this out. thanx a lothere's some of my code:
inside the construtor of a panel
graph = new Graph(new DefaultGraphModel(), new GraphLayoutCache());
// JLayeredPane
jlayeredPane = new JLayeredPane();
// jlayeredPane.setMinimumSize(new Dimension(400,400));
jlayeredPane.setPreferredSize(new Dimension(400, 400));
jlayeredPane.add(graph, JLayeredPane.DEFAULT_LAYER);
jsp= new JScrollPane(jlayeredPane);
jsp.addComponentListener(this);
add(jsp, BorderLayout.CENTER);
public void componentResized(ComponentEvent e) {
int layeredPaneWidth = jlayeredPane.getWidth();
int layeredPaneHeight = jlayeredPane.getHeight();
int viewportwidth = jspLayered.getViewport().getWidth();
int viewportheight = jspLayered.getViewport().getHeight();
int width = Math.max(layeredPaneWidth, viewportwidth);
int height = Math.max(layeredPaneHeight, viewportheight);

( (JTextPane in JScrollPane) in JTabbedPane)???
JTextPane textarea = new JTextPane();
JScrollPane scroll= new JScrollPane(textarea);
JTabbedPane tab = new JTabbedPane();
tab.add(scroll);
Now the problem is when i create many tabs and put
it in my window , and i want to jump from one tab to
another , the textpane does not get the focus .
tab contains scroll as its client so it gives focus to the
scroll but i want the textarea to have the cursor.so that there is no need for the user to click in the textarea to gain focus.
I hope some one understands my problem and helps me ...
thanks alot......I'm running JDK1.3 on windows 98. The requestFocus() method does not work unless it is executed after the JFrame is shown. Maybe this is your problem. The following sample program will help illustrate this.
1) run the program as is. Focus should be on the text area as you select a tab.
2) Comment out the 'newTab' methods in the main method. Uncomment the 'newTab' methods in the constructor. This time focus will remain on the tab as you select it.
Hope this helps.
