Resizing GridEditor redraw issues [message #15697]

Trying to code up a Grid with an GridEditor using a Text Widget.
But I'm running into redraw problems, as the Text widget flickers over the
the GridColumn header as the shell gets resized.

Below is the code I'm using.
Is there anything I'm doing wrong??

--------------------------------------
Grid grid = new Grid(shell,SWT.BORDER | SWT.V_SCROLL | SWT.H_SCROLL);

grid.setHeaderVisible(true);

GridColumn column = new GridColumn(grid,SWT.NONE);

column.setText("Name");

column.setWidth(300);

GridItem item1 = new GridItem(grid,SWT.NONE);

Text text = new Text(grid, SWT.NONE);

text.setText("my Item");

item1.setText(text.getText());

GridEditor editor = new GridEditor(grid);

editor.setEditor(text, item1, 0);

editor.grabHorizontal = true;

Hi Asim,

What you're seeing is a result of a issue in SWT thats since been fixed.
See:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=105764

I'm assuming you're running Eclipse 3.2. The bug has been fixed in 3.3
and I need to make some follow up changes in GridEditor.

Are you running 3.3?

Regards,
-Chris

Hi Chris

Just tried it with Eclipse3.3M2 and encountered the same redraw glitches.
This was using jdk1.5.0_08.

Playing around, I commented out the line "editor.grabHorizontal = true;"
and redraw works without a problem, but the editor functionality seems
to be disabled.

(Are there any snippets that include GridEditor ?)

---------------
import org.eclipse.swt.SWT;
import org.eclipse.swt.layout.FillLayout;
import org.eclipse.swt.nebula.widgets.grid.Grid;
import org.eclipse.swt.nebula.widgets.grid.GridColumn;
import org.eclipse.swt.nebula.widgets.grid.GridEditor;
import org.eclipse.swt.nebula.widgets.grid.GridItem;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.widgets.Text;

public class GridTest
{
public static void main(String[] args)
{
Display display = new Display ();
Shell shell = new Shell (display);
shell.setLayout(new FillLayout());
Grid grid = new Grid(shell,SWT.BORDER | SWT.V_SCROLL |
SWT.H_SCROLL);
grid.setHeaderVisible(true);
GridColumn column = new GridColumn(grid,SWT.NONE);
column.setText("Name");
column.setWidth(300);
GridItem item1 = new GridItem(grid,SWT.NONE);

Text text = new Text(grid, SWT.NONE);
text.setText("my Item");
item1.setText(text.getText());
GridEditor editor = new GridEditor(grid);
editor.setEditor(text, item1, 0);
//editor.grabHorizontal = true;

shell.setSize(250,250);
shell.open ();
while (!shell.isDisposed()) {
if (!display.readAndDispatch ()) display.sleep ();
}
display.dispose ();
}
}
