MIDP 2.0: Positioning the caret

Deep joy.
On the Sun emulator, I can position the text insertion caret into a text field by calling setText( String) on that field. However, when I deliver the MIDlet onto the device using IBM's j9 MIDP2.0 implementation, it doesn't work. I've read through the MIDlet documentation, and I cannot see any official means of setting the position of the text insertion caret.
What am I missing?

Thank You for ur help. I have now used the PRESSED methods to allocate most of the keys. I have one final question though how do u use the star and hash symbol because it isnt under the pressed methods on the key methods and this mucks all the keys up. Is there another way of using these keys without using the key method from canvas.

How to get the caret position of component embedded in JTextPane?

Hi great java developers ;-)
I want to get the caret position of component which is embedded in StyledDocument / JTextPane.
How has it to be done?
Thank you very much!!!

The Document doesn't know which textPane it belongs to. (It could even be shared by mulitple textPanes).
You get the caret position of a any text component by using:
textComponent.getCaretPosition();

Set a popup Dialog to just below the caret position in TextField

I have a JTextArea in which I wish to show up a popup dialog box whenever the user presses Ctrl and I want the popup to be visible just below the caret position where the user presses Ctrl. I'm using modelToView() but I'm not able to achieve the target.
If anyone can help...

You may find this usefull (if you have not already)

If you have seen that and it still doesn't work we need an example to work with (as the above poster says) as you havn't even really explained what is going wrong!

How to change the size of the caret in a JTextPane

I have text of different font sizes and the default caret height is the height of the text with the maximum font size. How do I change the caret height so that it matches the height of the text with the specified font size ?

This has been a real pain in the butt to figure out, but I think I finally got it. If you create your own caret (subclass of DefaultCaret) then you override its paint() and damage() methods. I was having all kinds of problems with this though. I was getting pieces of carets left behind when I moved with the arrow keys, etc... from the helps I found. The arrow keys were my big problem.
I think I finally figured out that the damage() simply does need to specify an area a little bigger than the old caret so it can blank it out. Then I think others had a logic problem, and Sun does not make this problem clear. What happens it that I think repaint() calls paint() who then uses the bigger x, y, height and width parameters that got set in damage(), which was causing my problems because the damage size was bigger than the size I wanted to create my caret with. What I do is figure out my area from the font I am using (another trick) and make them (the charWd and charHt) variables class variables. I calculate them in damage, use a bigger area to blank out my old caret in damage, and then used the correct caret size I calculated in damage() in paint(), instead of the rectangle values that seem to get passed from damage() to paint(). That was the problem in other examples.
Here is my code:

How to insert a String at the CaretPosition without moving the Caret?

I have a JTextPane wrapped by a JScrollPane. The JTextPane is where chatroom messages appear. When a message is appended at the end, it determines whether to scroll to the bottom based on some conditions (scroll to the bottom only if the user was already viewing somewhere near the bottom). That part is working fine.
Although the JTextPane is not editable, it allows the user to make selections using a mouse so that blocks of text can be copied from the chatroom. The default caret of JTextPane handles that for me.
But the problem comes when the caret position is at the end of the document when my program inserts a new message with the following code:
StyledDocument doc = textPane.getStyledDocument();
doc.insertString(doc.getLength(), message + "\n", null);The caret was at doc.getLength() to begin with, when the new message is inserted at the end, it "pushes" the caret to a new position. The caret movement is causing JScrollPane to scroll to where the caret is visible (the bottom), therefore interfering with my scrolling algorithm (see above).
So, when the caret is doc.getLength(), how do I insert a String at doc.getLength() with the caret staying at the original position?
In other words, how do I insert a String at the caret position without the caret being moved?
Note:
1) I don't want to use setCaretPosition() to set the caret to its original position, because calling this method will trigger a CaretEvent, thus causing the JScrollPane to scroll (to the caret) which is not what I want (see above).
2) I don't want to remove the CaretListener, cause then the JScrollPane won't scroll even when the user wants to make a multiple-page selection using the mouse (dragging the selection off screen).
3) I want to keep the Caret at the original position so that the user won't lose his/her selection when new messages appear (which can be quite frequent).

I keep forgetting how difficult it is to do such simple things in the text package. But it's not impossible! Here's a way to replace the relevant listeners, plus a sample implementation. If you know you'll never, ever delete any text from the JTextPane, you may not have to provide a replacement DocumentListener at all; this one just makes sure the caret isn't past the end of the document.

Links to named destinations in IFRAME positioning the PDF a page and half past

I created a PDF file w/ named destinations so that I can allow the Internet user w/ browser and Acrobat Reader plug-in to link to specific sections of the PDF. The zoom is set to Fit Horizontally, and the position is the top of the page in my example PDF. I used Acrobat Pro 8.1 to create the PDF.
Problem is when trying to load the PDF into an IFRAME, displayed with the named destination using a tag like:
<a href="http://ekensqldev5/ePadmin/documents/Raw.pdf?rand=1000#view=FitH&nameddest=Mission" target="myframe" >Click 1 </a>
When clicking on the link to the named destination, the .pdf is loaded or reloaded into an IFRAME and the page with the named destination is usually correctly displayed. Only in IE 6,7,8 the pdf will frequently (about 1 out of 4 times) be positioned a page and a half past the named destination. Clicking to a different link, and then back to the original link will usually reposition the PDF correctly. Chrome and Firefox always position the PDF exactly to the named destination. I'd like to know how to create the named destination so that it will always be positioned correctly, or to use a different link that will always position correctly. I'm using Reader 9.1.2

I'm working with Lyle on this, and I have done some additional testing.
What I found is that the positioning for named destinations seems to work ok with IE8 when the html page and pdf file are located on one of our external web servers (rather than local intranet servers).
I am wondering if this is due to the latency involved in downloading the file, allowing the DOM to register the plugin?
I've posted a query at Microsoft's forum, but they are pointing me back to Adobe...saying they cannot know how the plugin handles rendering...even though I responded that it seems to work across the board with Firefox and Chrome.
Here is my thread in the Microsoft forum.

How to position the cursor in a text

I there a better way to position the cursor in a text portion other than trying it several times until the OS picks the right space? I know the iPad has a good way to do it by zooming in.
Or is RIM working on it.....

I've been pretty successful at getting the cursor to hit where I want in text entry boxes.
Maybe some more practice will make perfect. Worked for me, until I got used to,and then again maybe my using a touchscreen smartphone, the process just comes second nature for me.

How to get the caret inside a custom editor?

I was reading through old posts the other day and noticed this by Rob Camick in this thread Re: Problem in cell selection in JTable Java Swing :
camickr wrote:
All KeyEvents are passed to the editor for the cell and the editor is psuedo invoked. That is, the caret is not placed on the text field used as the editor, but the character typed is added to the editor.This set me thinking about a known issue in my app which I had shelved for a "rainy day": how to get the caret into the cell editor component. I thought I'd get it out and look at it. I tried the following, in my custom cell editor:
public Component getTableCellEditorComponent(JTable table, Object value, boolean isSelected,
                                             int row, int column)
    JTextField ec = (JTextField) editorComponent;
    ec.setText((String) value);
    if ("".equals(ec.getText()))
      ec.setCaretPosition(0);
    else
      ec.selectAll();
    return editorComponent;
}But it has no effect whatsoever, the user still can't type something in and then press the backspace key to useful effect. Has anyone out there solved this problem? (And why, oh why, is the caret not put into the cell editor by default, if it's a component that has a caret?)

Replying to my own post, in case what I ended up with is of some help to others. The desired behaviour was that anything the cell contained from the previous edit would be replaced by what the user types in the current edit, i.e.:
user starts edit, types 234, stops editing, cell displays 234...user single-clicks on cell, types 567, stops editing, cell displays 567
My code is as follows:
    public Component getTableCellEditorComponent(JTable table, Object value,
                                                 boolean isSelected, int row,
                                                 int column)
      final JTextField ec = (JTextField) editorComponent;
      ec.setText((String) value);
      // selectAll, so that whatever the user types replaces what we just put there
      ec.selectAll();
      SwingUtilities.invokeLater(new Runnable()
        public void run()
          // make the component take the keyboard focus, so the backspace key works
          ec.requestFocus();
          SwingUtilities.invokeLater(new Runnable()
            public void run()
              // at this point the user has typed something into the cell and we
              // want the caret to be AFTER that character, so that the next one
              // comes in on the RHS
              ec.setCaretPosition(ec.getText().length());
      return editorComponent;
    }

How to position the cursor at the end of the text with EDIT_TEXT?

Hello, it wanted to ask to them if somebody could make work the module of function EDIT_TEXT so that it positions the cursor at the end of the text that is visualizing in the text editor. In the documentation it says that passing a ' X' to him in the field scrollend of the parameter Control is obtained that operation. Nevertheless, I did this and the cursor continues appearing at the beginning of the text that visualizes.
Somebody could help me please?

Murugesh,
I believe that you have mis-read Gabriel's problem.
Gabriel,
The cursor is not positioning at the base of the editor as you have cited.
In order to get this functionality to work, you must set the LINE_EDITOR import paramter to 'X'.

Why is my BDC_CURSOR command not working to position the cursor?

Why is my BDC_CURSOR command not working to position the cursor? Here are the details regarding my issue.
I am writing a BDC to mass delete routing material assignments using transaction CA02. I am OK to navigate through the initial screen to go to the Header screen and from here I am OK to navigate to the Material Assignments screen. But once here, I cannot get the BDC_CURSOR command to take me into the list. Here are the commands I am using. Please let me know what I may try differently.
CA02 Material Assignment - Set position <-- this resets list of materials to correct position
PERFORM bdc_dynpro      USING 'SAPLCZDI'   '1010'.
PERFORM bdc_field       USING 'BDC_CURSOR' 'RC27X-ENTRY_ACT'.

PERFORM bdc_field       USING 'RC27X-ENTRY_ACT' c_position.

Thank you for your reply.
I had used SM35 to record. However, I was not aware of the "create program" feature. I had commented out a section from my previous post which I have now added back (latest code below). But it still did not resolve the issue.
When I execute with dismode = 'N', I get back error message "No batch input data for screen SAPLCZDI 1010".
When I execute with dismode = 'E' (only show dynpros when error), it stops at the material selection screen without placing my cursor in the list. I can then MANUALLY click to set the cursor position in the list, MANUALLY click the trashcan, it then uses my BDC command to respond to the popup asking "Do you want to delete", still leaving me at the material selection screen. I can then MANUALLY click the green check (or enter), then it continues with the BDC to go back to the previous screen, and saves. But it still will not place my cursor in the material selection list (SAPLCZDI screen 1010).
Here is code used. It is the second section of code labeled "CA02 Material Assignment - Delete" that is not working.

Creating a bitmap copy of a TextFlow object without the caret [cursor]

Hey all
I'm currently working on creating a bitmap copy of a TextFlow object and I am looking at hiding the caret. What would be the best way forward, using the focusmanager to 'unfocus' the TextFlow object, or is there some more direct approach available? I know there is a cursormanager in Flex, but this is an AS3 only project.
Cheers for your thoughts once again
emd

I think I've just done something similar to what you need (except I'm adjusting the width of the bitmap according to that of the text), and so far I have seen no cursor
Here's the code. You'll need to adjust it depending on how many containers (Sprites) you are drawing the TextFlow to.

How to change the caret/selection color of text input controls?

Hello JavaFX Community,
i'm new to JavaFX. I'm using it since i saw the huge steps forward with version 2.0.
I have the task to migrate a software from Swing to JavaFX. As a part of our corporate design, we used a special color for the caret and text selection. I couldn't find any information about changing the caret color in JavaFX 2, so i'd like to ask you and i'd be very thankful for an advise.
There is a cross-post at StackOverflow:
http://stackoverflow.com/questions/10057989/how-to-change-the-caret-color-in-javafx-2-0
Thanks and best regards.

This might be possible, but it is not trivial. You cannot do it with a standard API at this time, you will have to look into creating a skin that allows for these properties to be controlled.
For example, the color of the caret is currently controlled in the TextFieldSkin (look for the "caretPath" property). Just forcing a color change in a subclassed skin is not so hard. Something like this:
public class MyTextFieldSkin extends TextFieldSkin {
public MyTextFieldSkin() {
this.caretPath.fillProperty().unbind();
this.caretPath.fillProperty().set(Color.RED);
}However, it gets trickier if this color must be dynamic and if you want other things to be changed as well. It is a place to start though.
Many of the skins methods and properties are 'protected' though, so atleast in Skin subclasses you have a lot of options to introduce new features and behaviour.

How to get the location of the caret?

Hello
I want to get the location of the caret. Not the offset of the document.
I have tried the Caret.getMagicCaretPosition(), but I think it gives me a point in viewport.
How can I get the absoult location of the caret(the location on screen ,not in viewport)?
Thank you very much.
Best wishes

Thankyou ,You reply seems to help me ,but I am still confused that this method returns void ,how can I get the result of the point on screen?
When I want the caret location (the caret belongs to a JTextPane) on screen, I invoke :
SwingUtilities.convertPointToScreen(textPane.getCaret().getMagicCaretPositon(),textPane);
but how can I get the result of the convertion?
Thank you!
