JTextArea

I have

Code:

---

    public void sM(String s, Color c) {
        jTextArea1.setForeground(c);
        String textAreaText = jTextArea1.getText();
        jTextArea1.setText(textAreaText + s + "\n");
    }

---

and when I do

Code:

---

sM("Hello", Color.red);
sM("Hello", Color.blue);

---

the text stays blue, but I want it to be in different colors.

You'll probably need to delve into using either JTextPane or JEditorPane. The tutorials can show you how, but it's a bit more complex then using JTextAreas.

A JTextArea can have only one foreground color; changing it to red and immediately changing it to blue (again) leaves the forground color of the entire area to blue.

I think I am doing something wrong to my sM method, because when I do

Code:

---

sM("Hello", Color.red);
sM("Hello", Color.blue);

---

the text is like this :
Hello
Hello.
But I want it to be like:
Hello
Hello.

Don't use a JTextArea but one of the decorated text panes instead: JTextPane or JEditorPane.

We have already told you. Please re-read the first reply (and the other replies) in this thread.

Much luck.

I have.

I'm not sure how to write my method. Because if I do this :

Code:

---

jTextPane1.setText(jTextPane1.getText() + "\n" + jTextPane1.setForeground(c) + s );

---

I get an error.

You will have to study the tutorials. As I noted, using a JTextPane or JEditorPane is not as straight forward as using JTextArea as I believe that you might need to use SytledDocuments, AttributeSets, EditorKits, etc... (it's been a while since I've looked at this). You may also be able to get different colors by using HTML tags, but I've not tried this myself. The tutorials and the API can get you started, but plan on needing a little time to study it before you can get it implemented.

Again much luck.

I wonder if you actually did read all replies. Well, did you? If so why are you stubbornly trying to accomplish something that can only be done that (ludicrous) way in your imagination?

ps. A Color is not a String, nor will a JTextArea understand it, and read the API to see if a setForeground( ... ) method returns a value. hint: it doesn't so it can't be used in way you are trying to do.
