Hello,
my TableViewer doesn't refresh. I have a table with buttons and i want
to dynamically change the length of the rows and the columns. After i
change this i call the function
createPartControl(getViewSite().getShell()); in this function i call
viewer.refresh() at the end. But it doesn't change only if i close the
view and open it again. Can somebody help me?
Greetings

.... and once more the question back:
1. What is the length of rows:
------------------------------
a) height of one row (first 10px, afterwards 20px)
b) number of rows in the viewer (first 10 rows, afterwards 20 rows)
2. What is the lendth of columns:
---------------------------------
a) width of a column (first 10px, afterwards 20px)
b) number of columns in the viewer (first 10 rows, afterwards 20 rows)
You should read the JavaDoc of the method:
--------8<--------
Creates the SWT controls for this workbench part.
Clients should not call this method (the workbench calls this method
when it needs to, which may be never).
--------8<--------
1. The first and most obvious thing is:
---------------------------------------
That I'm quite sure that the Shell is not the parent of View/EditorPart
2. Even if this would be correct you would create a second control in
this view-part, the old don't vanish when you call createPartControl
I for now suppose your use case is 1b) and 2b).
1b) Why isn't calling refresh() enough this will completely rebuild your
viewer from your input
2b) There are examples how to add/remove columns on the fly. I'd suggest
using the 3.3 TableViewerColumn-API but you are free to use the old API.
