Insert a JComboBox in a JTextPane

Hello !
I am working on a applet that will allow to the user to see a form.
But in this form (which is insert in a JTextPane) the user have to make choice for many varaibles.
So is it possible to add a JComboBox (where the user will make his choice) in a JTextPane
This will be something like : number.CHOICEoftheUSER.DATE
please anybody have a idea?
Thanks a lot

Not sure I understand why you want a combo box in a text pane, but you can use the insertCompnent(...) method of JTextPane.

Insert into JComboBox....

I am trying to insert another option into a JComboBox, however, I do not wish to append it. I need to insert it in between two other options. I cannot seem to find a method to do this. I know this is possible with JLists as you can specify an int and the object where the int is the position to insert. Despite searching I cannot seem to find a method that will take both and int and a object to place in the JComboBox. Any ideas would be helpful

Hi, the JComboBox class has a method called insertItemAt(). Have you tried using that yet?
(taken from the API)
====================================================================
public void insertItemAt(Object anObject, int index)
Inserts an item into the item list at a given index. This method works only if the JComboBox uses the default data model. JComboBox uses the default data model when created with the empty constructor and no other model has been set.
Parameters:
anObject - the Object to add to the list
index - an integer specifying the position at which to add the item

Why wont my buffered reader insert text files into my JTextPane?

Hello,
First off, I want to say that I am a java newbie. This is the first time I have ever worked with java, and only for about a month now. When I try running this, nothing gets inserted into my JTextPane, and I get a java.lang.NullPointerException error. Any idea of how to fix this?

Insert a JComboBox in a cell of JTable

Hi,
I have 3 comboboxes having different items, I want to add them in different rows of a JTable. I can add a JComboBox into a column using DefaultCellEditor but it will show either all items or the Items in the last ComboBox (if I call removeAll). What can I do? Can any one help me?

I think
you have to look for the XXXRenderer class or XXXCellEditor classes

How to insert formatted text in a JTextPane component?

Hello,
This is my first post in a java forum so i hope to get help :)
Anyway, i am facing some problems in developping my project , the project consists of a tool to provide text editing allowing text formatting like MS Word , it allows different font style , size , color , text alignment...etc
My program generates .html files i.e. the text formatting is obtained using html tags ...
My problem is when the user opens the file again , any text formatting is unsaved, meaning, he MOSt continue typing using the same font size , style...etc any change in the format is unsensed and surely not saved in the html file .
till now i can't doubt where exactly is my problem .. but i'll be here for any attempts to help me :)
Thnx a lot

unfortunately it doesn't work this way(or I am doing it wrong as I don't know anything about css)
If I set white-space: nowrap the text is displayed in one single line ( so probably I implemented it the right way)
but with white-space:pre he still ignores all the whitespaces!
reading the same text (from a microsoft sql server table)with a textarea component all whitespaces and line breaks are shown! there has to be a way to make the static text or label component act this way(I don't want to use the textarea component because it's ugly and doesn't serve for my purpose).
can anybody help me?
edit: observation:
if I use "nowrap" for the textarea component he still keeps all whitespaces WITHIN the string but displays the whole string in one line
but somehow he deletes white spaces in the beginning of the string
the static text/label components delete all whitespaces before AND within the string

Inserting text into JTextPane

I have a requirement where I need to insert some text into a JTextPane within its DocumentListener. I read somewhere that this is not a good practice. What would be the right way of doing this?
Basically, I'm listening to what user is typing and helping him by inserting some text automatically based on user choice.
Please provide code samples.

Hmmm - not knowing anything about the document listener - maybe they were talking about some kind of loop, where you insert text and then it triggers the listener to insert text which triggers the listener to insert text.... etc.
Maybe there are some other user input listeners, such as the keyListeners which might be better?
I haven't even had a look at the JTextPane API at the moment, so I don't know what I'm talking about.
Cheers,
Rene

Inserting text from one JTextpane to another

How do i insert text from one jTextpane to another with the attributes i used in the first. Please help.

i'm using a defaultstyleddocument. Also.....if u know
how i can transfer this data through a
DataOutputStream to another computer.Hi again,
DefaultstyledDocument uses a tree-structure with classes in it, that implements the Element-Interface to hold the styles. It is very easy to get the plain text, but what you need to transfer a part of text from one JTextPane with DefaultStyledDocument in it to another with the same document-style in it, is a sequence of (string, AttributSet) - pairs, so you are able to insert them in the destination document by the insertString(...)-method.
It is easy to get the Element by postion from the document and retrieve the Attributset from it that it uses in that position. I guess, an approach would be, to do the following:
get the Attributset at the start of the text = AttributSet of the pair
scan the document until the set changes
extract the string from start to the position right before the set changes = string of the pair
store the (String,AttributSet)-pair in a Vector
do this in the same way, but this time the "start" will be the position of the start of the new Attributset that causes the end of the scan above.
When this is done for the hole text, that is to be transferred, you have a Vector with the String-AttributSet-pairs that you can use to insert them in the other JTextPane by calling the
insertString(...)-method with this values.
Tell me, what you are thinking about that - I don't know another method for this and had to create a solution on the fly for you, so that is perhaps not the best way to do it.

Make an inserted component in JTextPane not deletable ?

Hi all,
I insert some buttons in my JTextPane and of course I have to make them not eraseable, it is said that when they are inserted, they cannot be deleted by pressing the delete key. How can I do this ? Can I set some portion in a JTextPane not editable and another portion editable ?
Thanks

You have to extend document and override remove(int offset, int length) method. In the method just check whether specified (by offset and length) part of the document contains component. If not call super.remove() in other cases just return.

Getting Components inserted into JTextPane?

Hello,
OK, I can insert Components into a JTextPane. But how do I get them back out when I need to manipulate them? In other words: how are inserted Components stored by the JTextPane? And how do I get access to them?
Thanks for any help,
-Michael

try this out
Component[] containers=textPane.getComponents();
cheers.

Inserting components to JTextPane

Hi,
I need to insert components to JTextPane. I know JTextPane provides a method insertComponent() for this purpose.
But this does not work when you set the content type to "text/html".
For example if I do the following:
JTextPane textPane = new JTextPane();
textPane.setContentType("text/html");and then try to insert a component it does not work.
My question is, can I insert a JLabel/JButton to JTextPane once I set the content type to "text/html"?

My question is, can I insert a JLabel/JButton to JTextPane once I set
the content type to "text/html"? You don't really know what you did, do you?
No, you can not add other widgets into a JTextPane since it's not a container. That is completely irrelevant from the fact that you can specify a MIME type for what's written inside the text pane.

Hyperlink in JTextPane - It's not a hyperlink, what's wrong?

Hi,
I tried to insert a hyperlink into a JTextPane, but it looks like normal text and it has to much space to the rest of the inserted text, when refencing the JTextPane-Object "txtPane" to a HyperlinkListenerImpl()-Objekt and insert the strings with the method addHyperlinkA(url, sTxtSplit). Do you have any idea what the problem is? Here is the complete sourcecode.

Hi thechrimsonrabbit,
Is your home page ''about:home'' or is it ''http://www.google.com''. The ''about:home'' is the default Firefox home page with a google search built in. The second link is the actual google page. You might want to save that as your home page if you want all the extra tabs.
Hopefully this helps!

Tables in JTextPane

Hello dear Java Developers,
i have one question about how to visualize an editable Table on a JTextPane. I Know i can input HTML-Code in a JTextPane and it can display all HTMl Components like Images and Tables, but i need generate a table without HTML. My JTextPane has a DefaultStyledDocument in it and i basically know how to actually draw a Table inside the JTextPane.
To insert an Element, which represents the table, into the Document my Code looks like this:
MyTable table = new MyTable(rows, cols); //MyTable is just the logical representation of a table (rowCount, columnCount, etc ...)
try
Style st = target.addStyle("table", null);
((MutableAttributeSet)st).addAttribute(AbstractDocument.ElementNameAttribute, TableElementName); //TableElementName is a static constant
((MutableAttributeSet)st).addAttribute(StyleConstants.NameAttribute, table);
target.insertString(position, " ignored string ", st); //target is an instance of StyledDocument
After i do that my ViewFactory produces the view for this table:
public View create(Element elem)
String kind = elem.getName();
if (kind.equals(TableElementName)) //if its my previously created TableElement
MyTableView tbv = new MyTableView(elem, View.Y_AXIS); //create MyTableView
return tbv;
return super.create(elem);
My TableView is a BoxView and it contains other BoxViews, which represent Rows and Cells. Each CellView draws a border on its boundaries to visualize the table border. The result inside the JTextPane looks like this: http://img571.imageshack.us/i/tablei.png/
Now i can only type text before or after that table, but i want to be able to type inside each cell, and obviously i cant do it if i have one View for all cells. The Document of the JTextPane contains all the text elements and the tableview is just one element, something like a char or so, and i can only place the caret either before or after the table.
My idea now is to realize one simply cell: i want to be able to draw borders around a specific editable textpart and maybe change the background color, just the usual table stuff. But i don't know how to realize that. Are here any experienced developers who can give me a hint or a simple example for my problem?
I know that the HTMLEditorKit has the function
insertHTML(HTMLDocument doc, int offset, String html, int popDepth, int pushDepth, HTML.Tag insertTag)
i tried to use this function and to debug it to see how they realize a tableview but it is based on HTML and also it's way to complicated and it blew up my head.
thanks in advance

Honestly i dont really know if its possible to display tables by inserting HTML-Code inside the JTextPane, but i know that it is possible to display editable tables inside the JTextPane.
The open source projekt http://shef.sourceforge.net/ gives an implementation of a Wysiwyg HTML Editor. Tables with borders work very good there, but it makes use of the HTMLEditorKit (see the function insert( ... ) above). This application uses a JEditorPane, i use a JTextPane (subclass of JEditorPane) so i should be able realize tables.
My application is not related to HTML in any kind and i use my own EditorKit and ViewFactory. All i want to do is display is a simple cell with border and being able to type text inside that cell. Fact is my StyledDocument (DefaultStyledDocument to be correct) has a Tree of Elements, the LeafElements will be displayed. Right now my TableView is a LeafElement and i can't place the carret inside a LeafElement. Somehow i have to tell the Document that the Cell is a branch element abd to draw a border around it, but i don't know how to do that because it is so poorly documented and i don't know where to find example code.

JLabel in JTextPane - how to make the JLabel be highlightable

Hi,
This follows on from this post :
http://forum.java.sun.com/thread.jspa?threadID=741036&tstart=0
I'm inserting a JLabel into a JTextPane, and want it to look like the other text there. However when you select the text, the JLabels don't have the highlight painted on them. Does anyone know how to make the highlight be painted over the label?
I've tried looking at the Highlighter, HighlightPainter classes but as yet no joy.
thanks a lot,
Tom

If I understand what you're after you may find the following will achieve it:
((DefaultHighlighter)textPane.getHighlighter()).setDrawsLayeredHighlights(false);Don't ask me why, though!!
Hope this helps.

Tables in JTextPane (colored borders)

I am working on an html Editor.
I try to insert a table, i use the class Action, like you can see just down.
i succeed in inserting rows and cells but i failed in having a border in my table.
I share my editor iin two parts : edition and source where i can see the relevant html source. When i see the relevant html source and change it to insert colored borders, there are not consequences in the editing part (on the HTML Document). Why??
HashMap _editActionMap= new HashMap();
Action[] action = kit.getActions();
int ind = 0;
for ( int iIndex = 0; iIndex < action.length; iIndex ++ ) {
_editActionMap.put( action[iIndex].getValue( Action.NAME ), action[iIndex] );
ind++;
JButton table = new JButton("InsertTable");
table = toolbarEdition.add( (Action)_editActionMap.get("InsertTable"));
toolbarEdition.add(table);
JButton tableRow = new JButton("insert row");
tableRow = toolbarEdition.add( (Action)_editActionMap.get("InsertTableRow"));
toolbarEdition.add(tableRow);
JButton tableCell = new JButton("insert data");
tableCell = toolbarEdition.add( (Action)_editActionMap.get("InsertTableDataCell"));
toolbarEdition.add(tableCell);
