Hi,

I want to create a multiline Text control using the native Text widget.
The problem with the above snippet is that I cannot introduce more than 7
lines of text.
Well, in the examples provided by Eclipse (ControlExample) the Text control
created with SWT.MULTI it has'nt this limitation.
What is wrong in my snippet ?


import org.eclipse.swt.SWT;
import org.eclipse.swt.layout.*;
import org.eclipse.swt.widgets.*;

/**
* @author Robert Bacs
*/
public class XTableTest {
public static void main(String []args){
final Display display = new Display();
final Shell shell = new Shell(display);
shell.setLayout(new GridLayout());

Group textGroup = new Group (shell, SWT.NULL);
textGroup.setLayout (new GridLayout ());
textGroup.setLayoutData (new GridData (GridData.GRAB_HORIZONTAL |
GridData.HORIZONTAL_ALIGN_FILL | GridData.VERTICAL_ALIGN_FILL));
textGroup.setText ("Text");

Text text = new Text(textGroup, SWT.MULTI);
int size = 100;
GridData gridData = new GridData ();
gridData.widthHint = size;
gridData.heightHint = size;
text.setLayoutData(gridData);
text.setText("Multiline\nText\ncontrol");

shell.pack();
shell.open();

while (!shell.isDisposed ()) {
if (!display.readAndDispatch ()) display.sleep ();
}
display.dispose ();
}
}

1) Give it a vertical scroll bar using SWT.V_SCROLL (in SWT 2.1.x)
2) The problem has already been worked around in SWT 3.0 (SWT.V_SCROLL
should not be necessary but it's not harmful).

Hi,

Yes, I know that, but in the ControlExample it's working without
SWT.V_SCROLL and I'm runninng with the same SWT version both example
(ControlExample and my snippet).
What is the difference between my snippet and the example provided by
ControlExample ?
Because, I do not see any !

Best regards,
Boby

Hi,

I found the difference: in the Java build path I have two version of swt.jar
:).

Best regards,
Boby
