JFace TableViewer and MigLayout - Scrollbars
Hello! I am quite fond of MigLayout and I use it in my RCP project to create forms and the like. I also used it for SWT Composites containing a JFace TableViewer or JFace TreeViewer that scroll in both directions (SWT.H_SCROLL | SWT.V_SCROLL). Unfortunately I did not manage to configure MigLayout in a way that scrollbars are shown when I resize the Window (a Shell or RCP View, does not matter) so that the table is larger than the window (in which case scrollbars should appear; note: Scrollbars appear whenever the Table's contents are larger than the Tables size; obviously the table's size is not reduced according to the reduction in size of the window).
The following runnable snippet demonstrates the problem (note: you'll need SWT and JFace libraries, for example obtained by creating a RCP project with eclipse). When I use a normal FillLayout or GridLayout everything works fine. But how do I have to configure the MigLayout to achieve the same result (see lines 67/68)? Thanks for your help
