Appending text in Java's JTextArea
I have a problem with my text area.
I use jTextArea1.append("cleverly amusing");
to add the text..
FIRST APPEND:
then I use jTextAre开发者_JAVA百科a1.append("a fight");
to add the next text.
SECOND APPEND
What I Really want is to replace the "cleverly amusing" to "a fight". But I cannot do it. I tried to use the jTextArea1.removeAll();
but there's no effect. How can I remove the "cleverly amusing" so that I can append the "a fight" to the first line.
NOTE: "WORD HINT" is fixed...
What can I do?
If your JTextArea will only contain "WORD HINT: ..." then use the setText() method:
jTextArea1.setText("WORD HINT:\n" + word);
This will replace all the text with what you want.
BTW : removeAll() is part of the Container class, and is not to remove text but child components.
Why not use setText(String text)
instead of append(String text)
?
Instead of removeAll
, just call setText()
with the first line you want and then you can append the additional data if you want.
