How to make TableViewer resizable?

Answer 1

If you want to resize parts by dragging use a SashForm control to divide up the part in to two or more sections. You can then drag the sashes to resize.

If you have a limited number of controls you wish to show or hide you can use the exclude member of GridData and the control setVisible method:

GridData data = new GridData(.... )
data.exclude = true;
control.setLayoutData(data);
control.setVisible(false);

Reverse the exclude and setVisible settings to show the control. You will need to call layout(true) on the parent Composite to redo the layout.

You can also just create new controls as required in the Composite, again calling layout(true) on the composite.
