Hi, I have a question. When I have a layout with a textarea on top an
another one
on the bottom with a button, I don't seem to be able to get a newline to
work.
That \n-character in area.append only shows as two rectangles within the
text.
Also, if text is longer that the width of the text area, how can I make it
to
continue the text on the new line? Without parsing the String. Is there a
good and easy way to do this?
Here's the main part of the code:
FillLayout fl = new FillLayout();
fl.type = SWT.VERTICAL;
SashForm wholePane = new SashForm(shell_, SWT.VERTICAL);
wholePane.setBackground(whiteColor_);
SashForm textSash = new SashForm(wholePane, SWT.VERTICAL);
textSash.setBackground(whiteColor_);
SashForm inputSash = new SashForm(wholePane, SWT.HORIZONTAL);
inputSash.setBackground(whiteColor_);
wholePane.setWeights(new int[]{7,1});
Text area = new Text(textSash, SWT.SINGLE | SWT.VERTICAL );
area.setEditable(false);
area.setBackground(whiteColor_);
area.append("1234567890 \n 1234567890");
final Text input = new Text(inputSash, SWT.SINGLE | SWT.BORDER);
input.setBackground(whiteColor_);
Button send = new Button(inputSash, SWT.PUSH);
send.setText("send");
Thanks in advance.

Also, I would like to get a scrollbar in the text area on top.
And what's the keycode for enter key? I haven't found that anywhere.

You have created your Text widget with the style SWT.SINGLE - this means the
text widget can only have one line and \n will be treated as an invalid
character. Create your Text widget with the style SWT.MULTI to have
multiple lines.
To make the text wrap around to a new line when the text widget is not wide
enough to show the whole string, create Text with the style SWT.WRAP.
To get a scrollbar you need to create the Text widget with the style
SWT.V_SCROLL or SWT.H_SCROLL.
I think what you want is :
Text area = new Text(textSash, SWT.MULTI| SWT.WRAP | SWT.V_SCROLL);

Single line text widget. I have to send the written text forward when I have
typed in something and pressed enter.

For a single line text widget you need to add a Traverse listener:
public static void main (String [] args) {
Display display = new Display ();
Shell shell = new Shell (display);
shell.setLayout(new GridLayout(3, false));
Button b = new Button(shell, SWT.PUSH);
b.setText("Button 1");
b.addListener(SWT.Selection, new Listener() {
public void handleEvent(Event e) {
System.out.println(e.widget+" selected");
}
});
Text text = new Text(shell, SWT.SINGLE);
text.setLayoutData(new GridData(SWT.FILL, SWT.CENTER, true, false));
text.addListener(SWT.Traverse, new Listener() {
public void handleEvent(Event e) {
if (e.detail == SWT.TRAVERSE_RETURN) {
System.out.println("do something on
return");
}
}
});
b = new Button(shell, SWT.PUSH);
b.setText("Button2");
b.addListener(SWT.Selection, new Listener() {
public void handleEvent(Event e) {
System.out.println(e.widget+" selected");
}
});
shell.open ();
while (!shell.isDisposed ()) {
if (!display.readAndDispatch ()) display.sleep ();
}
display.dispose ();
}
