| Using layouts with complex widgets like tables or trees and computeSize() [message #451948] |

I've had a consistent problem when using a GridLayout (and other layouts)
when using mutliple tree/table widgets. The problem occurs when I ask both
widgets to take up available space (whether horizontal or vertical space).
The problem is the widgets are sized in relation to their contents. For
example, I have two tables layed out one on top of the other, with both
given GridData.FILL_BOTH. Initially both are sized equally because they
have no contents. Subsequently, if I add items to one table, then cause the
layout to be recalculated (on a resize for example), then the table with the
items can take up a large amount of space, even essentially hiding the other
table.
This is not how I would intuitively want the GridLayout to work. Complex
'containing' widgets like Tables, Trees and Lists I would expect not to size
relative to their contents. Is there a way to tell the layout, not to ask
for the preferred sizing of certain widgets? Is there any way to alter this
behavior? Am I the only one to encounter this?

Yes. You can set a widthHint or a heightHint. This hint overrides what
would normally be calculated with computeSize. You can still make the
widget grow larger or smaller than this value using FILL_BOTH.
