Hi all,
I wanted to make the cells of my table taller, and came across the following snippet of code to do so, from http:// www.java2s.com/Code/Java/SWT-JFace-Eclipse/ResizecolumnsasSW Ttableresizes.htm :

table.addListener(SWT.MeasureItem, new Listener() {
11 	   public void handleEvent(Event event) {
12 	      int clientWidth = table.getClientArea().width;
13 	      event.height = event.gc.getFontMetrics().getHeight() * 2;
14 	      event.width = clientWidth * 2;
15 	   }
16 	});

Problem is that there is no event called MeasureItem that I can find in RWT. Am I missing something, or is there some other way to change the height of cells in a table?

On the topic of resizing, is there also a way to change the height of the headers of ExpandItems? Basically I am trying to make these bigger for touch devices, so that they are easier to tap.

Thanks!

Hmmm, I kind of answered my own question Smile

Changing the padding for the Table-Cell in the css is one way to make the cell taller. Of course the padding is applied to all sides, so this will also increase your left and right margins. This is ok, in my case, but is there still a better way?

ExpandItem headers are still getting me. Increasing the font size is not affecting the size of the bar at all.

Hi Jim,

As you already discovered, there's no MeasureItem event in RAP. Theming
is the way to go. You can also specify different padding values for all
four edges of the cell.

Regarding ExpandItem: Do you increase the font size using CSS?

Regards, Ralf
