I am working on a chat application and I want the user to be able to change their font while typing messages. I tried using the setFont() method but it changes the font for the entire text within the JTextArea component and when the text is sent to the display area, another JTextArea component, the font changes do not appear. Instead i...

I am to make a cut and a replace method on JTextArea. I have the code for copy and paste, and I reckon I could just use that, in addition to just deleting the marked text in the JTA. How would the code for a code for cut and replace methods look like? The code for copy looks like this: public void copy(){ int start=ta.getSelection...
I have a curious problem with the JTextArea control: When I bring up my JTextArea everything is fine and whatever I type shows up without delay. However as soon as I send a FontSizeAction to my EditorKit(RTFEditorKit in this case, but it does not seem to matter which I use), a delay, from 1 - several seconds, happens. Interestingly the d...

Hi Geeks, It seems my current JTextArea instance is having line-spcing about 1 or 1.5. Can anybody tell me how to change the line-spacing in JTextArea instance? ...
So I'm stumped. I, for some reason, seem to remember that Java does weird things when you try to add new lines to stuff... so I think that may be the problem here. This code is not working how you'd expect it to: public void displayText(KeyEvent k){ txt = inputArea.getText(); outputArea.setText(txt); if(k.getKeyCode() == 1...
I had posted a question in regards to this code. I found that JTextArea does not support the binary type data that is loaded. So my new question is how can I go about detecting the 'bad' file and canceling the file I/O and telling the user that they need to select a new file? class Open extends SwingWorker<Void, String> { File fil...

I've used a static counter for counting number of characters entered in the textarea and also coded to handle the condition when user deletes any string from the text the counter must be incremented by conside...
Using Netbeans 6.8 (Mac Version) drag and drop tool for making the GUI, I have designed a JTextArea which the user should paste his data which the program will modify and show it to him. It is working fine; however, when I tried to paste about 65 thousand lines of testing data in the JTextArea, the GUI showed only a few of these lines (...
