Hi all,

I'm trying to use a CTableTree (with the experimental viewer) to display
a tree from an EMF model. However, I'm unable to display more than 2048
rows in the table. The remaining rows are simply greyed out, as shown on
this screenshot (modified snipplet to display 2050 rows):

Does anyone know why that is so?

cheers,
asgeir

I'm not able to reproduce this on Linux GTK so it may be a bug on the
Windows implementation - can you post a snippet showing this problem?

Hi Jeremy,

Here's a simple snipplet reproducing this:

CTableTree ctt =
new CTableTree(shell, SWT.BORDER | SWT.H_SCROLL | SWT.V_SCROLL);
CContainerColumn column1 = new CContainerColumn(ctt, SWT.LEFT);
column1.setText("Column 1");
column1.setWidth(200);

for (int i = 0; i < 2050; i++) {
CTableTreeItem item = new CTableTreeItem(ctt, SWT.NONE);
item.setText(new String[] { "item " + i});
}

I'm using nebula from eclipse cvs head.

cheers,
asgeir

Please log a bug for this with [WIN32] in the title. Thanks.
