Hi!

How do I dynamically add lines to a TableViewer? I don't have to setInput()
an array with all lines everytime I want to add one, do I?

Nope.

// Where
private StructuredViewer viewer;

// and
private List content;

// and you've initially done
viewer.setInput(content);

// thereafter doing
content.add("stuff");

//followed by a refresh
Display.getDefault().syncExec(
new Runnable() {
public void run() {
viewer.refresh();
}
}
);

// should work.

And what's content? setInput() requires a plain Object (something I yet
don't understand by the way :), the wizard per default passes
REsourcesPlugin.getWorkspace() to setInput().

Hi Timo,

Pass it a List of Objects that you want it to show (or a list of any
subclass of Object) - keep a reference to that List (hence the...

private List content;

in the earlier snippet) so that changing the content of "content"
(combined with the rest of the earlier bits) will change the content of
your table.

But this makes either the entire table to be redrawn or the content list to
be iterated for changes each time.

Use TableViewer.add(Object) to add items to your table. This is usually
done from your content provider, whose job is to keep your domain model
in sync with the viewer.
