SetCharacterAttributes sets selected text to p-implied tag

I am trying to remove all font attributes from the selected text. I have used the setCharacterAttributes with the replace option set to true for both the TextPane and the EditorKit. The result is the selected text is changed to "<p-implied>". If I set the replace option to false the method works as advertised but this doesn't help me. I have not been able to find any such beast in previously asked questions. Any ideas?

If you still do not have solution try this :
SimpleAttributeSet a = new SimpleAttributeSet(getInputAttributes());
a.removeAttribute(CSS.Attribute.FONT);
setCharacterAttributes(a, true);

How to set selected text on JTextPane ?

I need to set selected text on a JTextPane. I used setSelectionStart(); and setSelectionEnd(); but it doesn't work.
Can anybody help me?

I'm not sure if this is what you are looking for, but the following code sample was revised from the tutorial TextSamplerDemo.java. It will hightlight the word "selected" in yellow in the JTextPane.

How to customize the content set in text as part of tag cq:text property="text"/

We use the tag <cq:text property="text"/> to get the content, which is set in the jcr property "text". Text was set in Richtext component and it has hyper link.
Now, we have to customize the text.
Example:-
Actual Text in 'text' property:-
Click <a data-action="Hyperlink" data-upc-tooltip-type="none" href="/content/www-abc-healthcare-ch/en/offer.html">here</a> for the link 
After customization in 'text' property:-
Click <a data-action="Hyperlink" data-upc-tooltip-type="none" href="/content/www-abc-healthcare-ch/en/offer">here</a> for the link 
i.e .html has been removed.
I tried customizing and set back to text attribute using <c:set var="text" value="<CustomizedText>" /> but even after that tag <cq:text property="text"/> retrieves the old content i.e with .html
Please suggest how to override text content, so that the tag <cq:text property="text"/> will print customized text.

How to set selected text color in Spark TextInput

I'm trying to make Spark TextInputs and MXFTETextInputs look like Halo/MX TextInputs as much as possible, since I have a mix of both Spark and MX TextInputs in my application. I know I can set the
selection background color to black using focusedTextSelectionColor. How can I set the selected text color to white so it matches the MX white-on-black look?

This works, if you set the enabled property directly on the s:TextInput:
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
 xmlns:s="library://ns.adobe.com/flex/spark"
 xmlns:mx="library://ns.adobe.com/flex/mx">
 <s:layout>
 <s:VerticalLayout horizontalAlign="center" verticalAlign="middle" />
 </s:layout>
 <s:controlBarContent>
 <s:CheckBox id="ch" label="enabled" selected="true" />
 </s:controlBarContent>
 <fx:Style>
 @namespace s "library://ns.adobe.com/flex/spark";
 @namespace mx "library://ns.adobe.com/flex/mx";
 s|TextInput:disabled {
 color: red;
 </fx:Style>
 <s:Group>
 <s:TextInput id="ti" text="The quick brown fox jumps over the lazy dog" enabled="{ch.selected}" />
 </s:Group>
</s:Application>
It can get a bit trickier when you're setting the enabled property on a parent container, since (I believe) that the child control's enabled properties are still set to true and just the container is disabled. One possible workaround would be to bind the child TextInput control's enabled property to the container's enabled property. That way the s:TextInput should still go to it's disabled state and you can customize the disabled state's styles to have darker text, or whatever else you want.
<s:Group id="gr" enabled="{ch.selected}">
 <s:TextInput id="ti" text="The quick brown fox jumps over the lazy dog" enabled="{gr.enabled}" />
</s:Group>

Set selected text as variable (CS3 with JS)

How can I set a piece of selected text as a string variable?
I'm running InDesign with InCopy CS3 on a Windows XP computer.

If you mean "assign the selected text to a variable", then you could do this:
var myText = app.selection[0].contents;

JTextPane - setting selected text colour

Ok, I have a bit of a problem. Here is some general information about my program.
I have a JTextPane called "DDITextArea" and I can type in it and stuff. I want to be able to select some of the text and use a JColorChooser to set the text to that color of my choice. I am doing a bit of experimentation with the swing components and messed around with a JColorChooser. Here is the code for the chooser.
    ColourOption.addActionListener(new ActionListener() {
      public void actionPerformed(ActionEvent e) {
        if (first) {
          first = false;
          chooser.setPreviewPanel(new CustomPane());
        JDialog dialog = JColorChooser.createDialog(RecipeBrowser.this, "Demo 3", true, chooser, new ActionListener() {
              public void actionPerformed(ActionEvent e) {
                c = chooser.getColor();
            }, null);
        dialog.setVisible(true);
*I NEED SOMETHING HERE TO SET THE SELECTED TEXT TO THE COLOUR I CHOOSE WITH THE JCOLOURCHOOSER
*I HAVE A JTEXTPANE AND I WANT TO BE ABLE TO SELECT SOME TEXT THEN USE THE JCOLORCHOOSER TO SET THE COLOUR OF THE SELECTED TEXT
    });as you can see from the comments near the end of the code sample, I need to know how to set the selected text to Color c. I don't know if there is a method for this. I looked at the online Java syntax database but to no luck. Just to ensure that there is no misunderstanding I will give an example:
DDITextArea has the sentence "The dog is wet and smelly" and its default font colour is black. If I highlight the words "The Dog", open the ColorChooser and select red, the words "The Dog" will be red while everything else is black.
If it is any help, here is where my DDITextArea is created
          final JTextPane DDITextArea = new JTextPane();
          JScrollPane DDITextAreaScrollPane = new JScrollPane(DDITextArea, ScrollPaneConstants.VERTICAL_SCROLLBAR_AS_NEEDED, ScrollPaneConstants.HORIZONTAL_SCROLLBAR_AS_NEEDED);
          //DDITextArea.setLineWrap(true);
          //DDITextArea.setWrapStyleWord(true);
          DDITextArea.setEnabled(true);
          DDITextArea.setEditable(true);
          DDITextArea.setVisible(true);
          gbc.fill = GridBagConstraints.BOTH;
          gbc.anchor = GridBagConstraints.CENTER;
          gbc.gridx = 1;
          gbc.gridy = GridY;
          gbc.gridwidth = 1;
          gbc.gridheight = 1;
          gbc.weightx = 1;
          gbc.weighty = 1;
          gbl.setConstraints(DDITextAreaScrollPane, gbc);
          PrintTab.add(DDITextAreaScrollPane);Am I missing any necessary syntax to do this or is there something much more complicated involved?

Sorry for the double post but I figured it out. I missed the answer. This is a clear sign I must stop doing past-midnight research.
Anyways, for any folds that have trouble with this in the future, here you go. I hope someone, somewhere, sometime, will have need for this.
    ColourOption.addActionListener(new ActionListener() {
      public void actionPerformed(ActionEvent e) {
        if (first) {
          first = false;
          chooser.setPreviewPanel(new CustomPane());
        JDialog dialog = JColorChooser.createDialog(RecipeBrowser.this, "Demo 3", true, chooser, new ActionListener() {
              public void actionPerformed(ActionEvent e) {
                c = chooser.getColor();
            }, null);
        dialog.setVisible(true);
//THE CODE BELOW THIS COMMENT IS WHAT I ADDED
new StyledEditorKit.ForegroundAction("", c).actionPerformed(null);
//THE CODE ABOVE THIS COMMENT IS WHAT I ADDED

Can't set selected text in a JTextArea (bizarre)!

I've go this method here to select text in a JTextArea is doesn't work.
Any ideas?? I haven't posted ALL the code because there is quite a lot of it in a number of classes.
public void selection(int i)
          String meth = methods.get(i).toString();
          String tex = tc.getText();
          int pos = tex.indexOf(meth);
          if (pos != -1) {
               myTextComponent.setSelectionStart(pos);                myTextComponent.setSelectionEndpos+meth.length));
     }

Selected text is only shown when the text component has focus. Assuming you are clicking on a button to invoke your code you would need to reset focus on the text field:
myTextComponent.requestFocus();

Create new tag for selected text using API?

Hello,
I want to add new tag for the selected text just like 'Create Tag from selection' .
is it possible to create tag for selected text using acrobat api?
 please,help me.

As per sample of snippetRunner for adding tag for selected text.
I tried below code
PDPage pg;
AVDoc avDoc = AVAppGetActiveDoc();
PDDoc pd = AVDocGetPDDoc(avDoc);
 pg = PDDocAcquirePage(pd, 0);
ASAtom theSelectionType = AVDocGetSelectionType(avDoc);
if (theSelectionType == ASAtomFromString("Text")){
 PDTextSelect ts = static_cast<PDTextSelect>(AVDocGetSelection(avDoc));
 PDSTreeRoot pdsTreeRoot;
 CosObj pageObj = PDPageGetCosObj (pg);
 PDSElement newElem;
 PDSElementCreate(pd, &newElem);
 char buf1[64];
 strcpy (buf1, "A new structure element");
 // set its type as "Document" standard type
 PDSElementSetType(newElem, ASAtomFromString ("Document"));
 // set its title
 PDSElementSetTitle(newElem, reinterpret_cast<const ASUns8*> (buf1), strlen(buf1));
 PDSTreeRootInsertKid (pdsTreeRoot, aElem, kPDSAfterLast);
 PDSElementInsertMCAsKid // here something i have to add
If i have PDTextSelect how i can add tag for selected text.like user add tag using "CreateTagForSelectedText" option.
please,help me.
thanks.

Problem with focus and selecting text in jtextfield

I have problem with jtexfield. I know that solution will be very simple but I can't figure it out.
This is simplified version of situation:
I have a jframe, jtextfield and jbutton. User can put numbers (0-10000) separated with commas to textfield and save those numbers by pressing jbutton.
When jbutton is pressed I have a validator which checks that jtextfield contains only numbers and commas. If validator sees that there are invalid characters, a messagebox is launched which tells to user whats wrong.
Now comes the tricky part.
When user presses ok from messagebox, jtextfield should select the character which validator said was invalid so that user can replace it by pressing a number or comma.
I have the invalid character, but how can you get the focus to jtextfield and select only the character which was invalid?
I tried requestFocus(), but it selected whole text in jtextfield and after that command I couldn't set selected text. I tried with commands setSelectionStart(int), setSelectionEnd(int) and select(int,int).
Then I tried to use Caret and select text with that. It selected the character I wanted, but the focus wasn't really there because it didn't have keyFocus (or something like that).
Is there a simple way of doing this?

textField.requestFocusInWindow();
textField.select(...);The above should work, although read the API on the select(...) method for the newer recommended approach on how to do selection.
If you need further help then you need to create a "Short, Self Contained, Compilable and Executable, Example Program (SSCCE)",
see http://homepage1.nifty.com/algafield/sscce.html,
that demonstrates the incorrect behaviour, because I can't guess exactly what you are doing based on the information provided.
Don't forget to use the "Code Formatting Tags",
see http://forum.java.sun.com/help.jspa?sec=formatting,
so the posted code retains its original formatting.

How to set the desired font to the selected text in textframe?

Hi,
I want to change the font(let's say Times New Roman) of selected text in textframe when I click on menu-item of my plug-in.
I went through the Adobe Text Engine documentation and tried some code for setting font but failed. I don't see any member function in IFont class to set desired font, so unable to move forward.
plz see the code. I would like to know one more thing that how can we set a particular font for a textframe?
TextRangesRef rangesRef = NULL;
result = sAIDocument->GetTextSelection(&rangesRef);
aisdk::check_ai_error(result);
ITextRanges ranges(rangesRef);
if (ranges.GetSize() > 0)
     ITextRange range = ranges.Item(0);
     ICharFeatures features = range.GetUniqueLocalCharFeatures();
     IFont font;                     // I don't see any method to put desired font.
   // features.SetFont();
Thanks.
D.A

First, get the font:
AIFontKey fontKey = 0;
AIErr error = sAIFont->FindFont("Times New Roman Regular", kAIAnyFontTechnology, kNativeAIScript, 0, &fontKey);
// do something with error
ATE::FontRef fontRef = 0;
error = sAIFont->FontFromFontKey(fontKey, &fontRef);
// do something with error
ATE::IFont font(fontRef);
Then, apply it like this:
ATE::TextRangeRef textRangeRef = 0;
AIErr error = sAITextFrame->GetATETextRange(handle_to_artwork, &textRangeRef);
// check error
ATE::ITextRange textRange(textRangeRef);
ATE::ICharFeatures charFeatures = textRange.GetUniqueLocalCharFeatures();
charFeatures.SetFont(font);
textRange.ReplaceOrAddLocalCharFeatures(charFeatures);
There are a few other ways to set the text, but you need to understand how character & paragraph styles interact with each other to understand the differneces. This is the most straight forward way to do it though.

Adobe Acrobat. Change "Copy selected text into Highlight, Cross-Out, ..." also for highlights made before changing the setting

I am looking for a solution to apply the "Copy selected text into Highlight, Cross-Out, and Underline comment pop-ups" setting to highlights that I made before I changed this setting.
Someone wrote a batch for this which costs 60 dollar and this seems to do what I am looking for: Custom-made Adobe Scripts: Acrobat -- Retroactively Copy Highlighted Text into Comments
Where can I find Adobe's solution for this problem? I do not want to buy external batches for a professional software suit.
I expect that this is a common problem for people who start to organize a large literature base with many pdfs and must keep track of highlighted text. I was not previously aware of the "Copy selected..."setting, but I need to change it now for all my pdf files to make them compatible with a reference manager that I want to use. New comments are now compatible, but the hundreds(!) of pdfs that I worked through before are not, so copy pasting the highlighted text into comments is not an option.

[CS3][JS] Apply XML tag for selected text

Hi
I need to apply XML tag to selected text in a tagged content.The XML tag is already applied for paragraph.I need to apply XML Tag for selected text in a paragraph.
I have used following code, it applies tag for entire paragraph,not a selected text in a paragraph.
app.selection[0].associatedXMLElements[0].markupTag=myDoc.xmlTags.item("italic");
Please suggest me.
Regards
kumar

The example script, markup.jsx
//Markup.jsx
//An InDesign CS4 JavaScript
//Shows how to use the markup method.
main();
function main(){
 mySetup();
 mySnippet();
 myTeardown();
function mySetup(){
 var myDocument = app.documents.add();
 var myPage = app.activeWindow.activePage;
 var myRootXMLElement = myDocument.xmlElements.item(0);
 var myXMLTag = myDocument.xmlTags.add("xml_element");
 var myXMLElementA = myRootXMLElement.xmlElements.add(myXMLTag);
 myXMLElementA.contents = "This is a paragraph in an XML story.";
 var myTextFrame = myPage.textFrames.add({geometricBounds:myGetBounds(myDocument, myPage)});
 myTextFrame.contents = "This is the first paragraph in a text frame.\rThis is the second paragraph in a text frame.\rThis is the third paragraph in a text frame.\rThis is the fourth paragraph in a text frame.\r";
function mySnippet(){
 //<fragment>
 var myDocument = app.documents.item(0);
 var myPage = myDocument.pages.item(0);
 myDocument.xmlElements.item(0).xmlElements.item(0).markup(myPage.textFrames.item(0));
 //</fragment>
function myTeardown(){
function myGetBounds(myDocument, myPage){
 var myPageWidth = myDocument.documentPreferences.pageWidth;
 var myPageHeight = myDocument.documentPreferences.pageHeight
 if(myPage.side == PageSideOptions.leftHand){
 var myX2 = myPage.marginPreferences.left;
 var myX1 = myPage.marginPreferences.right;
 else{
 var myX1 = myPage.marginPreferences.left;
 var myX2 = myPage.marginPreferences.right;
 var myY1 = myPage.marginPreferences.top;
 var myX2 = myPageWidth - myX2;
 var myY2 = myPageHeight - myPage.marginPreferences.bottom;
 return [myY1, myX1, myY2, myX2];
I think you can use the markup function on the selected item (Text Object have a markup method)

Setting the text in ComboBox when nothing is selected

Hi, I want to ask you, whether there is any possibility to set text of a JComboBox, when nothing is selected. I want something like "Choose One" to be shown when no option is selected. Thanks for any help.

Never mind, I got it, you have tu create your own renderer and set the text for null value selected

JTree custom renderer setting selection background color problem

Hi,
I have a JTree with a custom icon renderer that displays an icon. The JTree is part of a TreeTable component. Iam having a problem setting the selection background uniformly for the entire row. There is no problem when there is no row selected in the JTable.
My present code looks like this:
Iam overriding paint in my renderer which extends DefaultCellRenderer.
 super.paint(g);
 Color bColor = null;
 if(!m_selected) {
 if(currRow % 2 == 0) {
 bColor = Color.WHITE;
 } else {
 bColor = backColor;
 } else {
 bColor = table.getSelectionBackground(); bColor = getRowSelectionColor();
 if(bColor != null) {
 g.setColor(bColor);
 if(!m_selected) {
 g.setXORMode(new Color(0xFF, 0xFF, 0xFF));
 } else {
 g.setXORMode(new Color(0x00, 0x00, 0x00));
 I have a color I arrive at using some algorithm that I want using method getRowSelectionColor(). The other cells in the row have this color. But the cell containing the tree node shows different color. Iam not able to arrive at the right combination of the color to set and the xor color so my tree node also looks like the other cells in the row.
It is not a problem really as the table still looks good. Its just that the tree node looks like it has been highlighted and this might cause a problem when a table cell is highlighed later on in the application ( two cells in the row would be highlighted causing confusion).
Any help would be appreciated.

vidyut

Hi Camickr,
Thanks for the reply. Iam sorry I didn't include the sources the first time around. There were too many of them. I have created a small, self-contained, compilable program that demonstrates the problem and including it herewith. Still there's quite many files but they are all needed Iam afraid. The only one you will have to concern yourself fior this problem is the file IconRenderer.java. The treenode background and the other cells background are not in sync when table row is not selected in this example though. But they are in my real program. I just need them to be in sync i.e have the same background color when the row is selected.
Your help would be very much appreciated.
These are the files that are included below:
1. AbstractTreeTableModel.java
2. Bookmarks.java
3. BookmarksModel.java
4. DynamicTreeTableModel.java
5. IconRenderer.java
6. IndicatorRenderer.java
7. JTreeTable.java
8. TreeTableExample3.java (contains main)
9. TreeTableModel.java
10. TreeTableModelAdapter.java

SetFont for selected text in JTextArea

Hi there,
I'm trying to build a small Texteditor.
How do you set a selceted area of text to fx. BOLD font?
I can of course set the font for the whole JTextArea via the setFont method, but what about a smal selection.
Also: setFont seems to take no less than 3 arguments (fontname, style, size). Is it possible just to set the selected font as the same as before, but BOLD??
Kind Regards
Thomas

Alright, so here I go :
I've been working for two months on a TextEditor/HTMLEditor, but I'm not allowed to share my code (I work for a company that wants to use this editor).
There are a lot of stuff that you should know about "javax.swing.text" package if you want to get initiated to Editors programming with Swing components.
Well, first of all, I'm going to answer to your punctual question :
You can't set style attributes ( color, bold, italic, ...) to specifc text elements in a JTextArea, you have got to use a JEditorPane or a JTextPane. (JTextPane lets you deal with the notion of "Styles"... but this is a bit complex for a simple editor, so I suggest you to just stick to the JEditorPane).
Any of these three Components has a document model related to it. These document models can be of different types. For example, PlainDocument, StyledDocument, HTMLDocument, etc...
A JTextArea can only have PlainDocument bound to it. These documents don't keep info about color, font, bold, and stuff for specific portions of text.They apply it to all content.
JEditorPane can have PlainDocuments, HTMLDocuments and I think they can have StyledDocuments.
To set bold to selected text you've got to do this :
        import javax.swing.text.*;
        int posStart = editorPane.getSelectionStart( );
        int posEnd = editorPane.getSelectionEnd( );
        int selLength = posEnd - posStart;
        MutableAttributeSet atr = new SimpleAttributeSet();
        StyleConstants.setBold(atr,true);
        StyledDocument doc = editorPane.getDocument();
        //Check out false in the following instruction
        // it means that any other attribute existing should
        // be kept if it has not be redefined in the attribute you are applying
        doc.setCharacterAttributes(posStart,selLength,atr,false);         That's it.. that's the way to do it.. the same principle applies for any other attribute,
for example if you also wanted to change font you could have added the following :
        StyleConstants.setFontFamily(atr,"Arial");Alright, so know I'm going to give you the good adresses to learn stuff about Editors, here I go:
* The Swing Connection Articles (hard to understand for a newbie but really helpful ):
http://java.sun.com/products/jfc/tsc/articles/index.html (Check out the TextPackage Articles)
* Manning Matthew Robinson and Pavel Vorobiev Swing book (it's all online for free)
This is the absolute reference, step by step examples. Check out Chapter 20 : Constructing a
Word Processor. (This is I guess the best stuff available online about constructing Text and HTML Editors in Java with Swing)
