Hi,

Is it possible to remove children from a Composite? I'm making a custom
list widget that contains a list of Labels positioned using a
GridLayout. My widget has a setItems(String[] items) much like the List
widget and I want to remove all old labels and create a new one for each
string and add it to the composite.

Regards,

Johan Tibell

To permanently remove a child from a Composite you call dispose() on the
child.

Alternately, if you want to reuse the child later on, with GridData you can
set the "exclude" flag as shown in this snippet:
