Problem: I need an SWT Table (JFace TableViewer) with variable row height. In fact, I solved this on my development machine (running Ubuntu 10.10). Unfortunately, this doesn't work on Windows nor on Mac.
Initially, I thought I didn't use the libraries correctly. But by now I fear that what I want to do is simply not possible on Windows. I hope someone here convinces me otherwise.
To reproduce: rather than providing my code here, I built a minimal program to reproduce the problem. I started with the following Snipplet:
I modified the update() method to produce two lines of text for directories and one line for files (to simulate an environment with variable row heights):
...
if (file.isDirectory()) {
cell.setText(styledString.toString() + "\n"
+ styledString.toString());
cell.setImage(IMAGE1);
} else {
cell.setImage(IMAGE2);
}
...
This works as intended on Linux, but on Windows all rows have the same height. Specifically, only one line is visible.
Next, I was trying to help SWT by making measure() more intelligent. So I rewrote measure() like this:
protected void measure(Event event, Object element) {
if (((File) element).isDirectory()) {
event.height = 32;
} else {
event.height = 16;
}
super.measure(event, element);
}
The result: All rows have the height 32. Again, this works as intended on Linux.
My fear is, that on Windows simply all rows must be the same height. This would be a showstopper for me. Can anybody confirm this, or even better, provide a workaround?
Thanks!
