Theres no automatic way to do this. What you would need to do is:
Add a KeyboardListener to the TextArea and in onKeyDown look for the number of
lines in the TextArea's content (plus one if the key is KEY_ENTER). Use
TextArea.setVisibleLines to make sure that the size of the TextArea is >= the
number of lines in it's content.
Something like:
final TextArea text = new TextArea();
text.addKeyboardListener(new KeyboardListenerAdapter() {
public void onKeyDown(Widget sender, char keyCode, int mods) {
int lines = 0;
final String content = text.getText();
for(int i = 0; i != -1; i = content.indexOf("\n", i + 1)) {
lines++;
}
if(keyCode == KEY_ENTER) {
lines++;
}
if(text.getVisibleLines() < lines) {
text.setVisibleLines(lines);
}
}
});
Should do the trick.
