Row height is based on the maximum value of either Font height or Image
height (see TableTree.setFont() and TableTreeItem.setImage()). There is no
independant way to set this. On almost all platforms, all rows must have
the same height.
Once an image is set into a Table (or TableTree) all subsequent images are
made the same size and there is no way to change the size of the images.
The size of the first image set in a table determines the height of all
images.
There is a problem in TableTree because as soon as the first TableTreeItem
is added to the TableTree, an image is created for the +/- and this
determines the height of all images that come after. Here is a hack to work
around this:
public static void main (String [] args) {
Display display = new Display ();
Image large = new Image(display,
Main.class.getResourceAsStream("images/image100x100.bmp"));
Shell shell = new Shell (display);
shell.setLayout(new FillLayout());
TableTree table = new TableTree(shell, SWT.BORDER);
TableColumn column1 = new TableColumn(table.getTable(), SWT.NONE);
TableColumn column2 = new TableColumn(table.getTable(), SWT.NONE);
//Begin Hack
TableItem bogus = new TableItem(table.getTable(), SWT.NONE);
bogus.setImage(large);
bogus.dispose();
// End Hack
for (int i = 0; i < 10; i++) {
TableTreeItem item = new TableTreeItem(table, SWT.NONE);
item.setText("item "+i);
item.setImage(1, large);
for (int j = 0; j < 3; j++) {
TableTreeItem item2 = new TableTreeItem(item, SWT.NONE);
item2.setText("item "+i+" "+j);
item2.setImage(1, large);
}
}
column1.setWidth(300);
column2.setWidth(200);
shell.pack();
shell.open ();
while (!shell.isDisposed ()) {
if (!display.readAndDispatch ()) display.sleep ();
}
display.dispose ();
}

I have tried out the code/hack youi suggested.But it did not seem to help.
Although the image was bigger then what i was getting previously.
So how do i progress ahead.
Do i need to write a new swidget ?
Also should future implementations of Tabletree should not have such
restrictions as it binds itself to firm restrictions & does not server the
purpose.
I request the SWT community members to please take it as a contructive
view for future implementaions.
