Hey,

i created my own view in a plugin. This view uses a table viewer for
displaying the input by default. Now i want to implement an option to
switch from the table viewer to a treeviewer. I know how the viewers are
working but i don't know how i can change the viewer in my View. There is
no "setViewer()" method or something like that. Does anyone know how i can
manage this?

regards

Matthias

One option would be to use a org.eclipse.swt.custom.StackLayout as the
top-level layout of your view and then you can easily switch between two
children, a tree and a table.

Hope this helps,
Eric

Hey,

thanks for your answer. I've found an example for the StackLayout on
google, but unfortunately it didn't work for me :(

There must be another way. I have already looked in the sources of the
eclipse SDK to see how they have implemented their search view. But i
found nothing.

a little update from me. I've now tried to set a new TreeViewer to my
viewer variable when i trigger the "View as Tree" action in the view. Then
i call the parent.redraw() method. So if i now trigger the action and
change the view size to trigger the redraw, i have both viewer in the
view, the old tableviewer and the new treeviewer... Is there a way to
repaint the view without changing the size to trigger it? How can i get
rid of the old viewer?

regards

Matthias

StackLayout is extremely simple - the Javadoc for it even has example
code. Perhaps if you describe what "didn't work" and show some code you
tried, then we could tell you what is wrong.

Hey,

schame on me. I now tried to use the StackLayout again. My very stupid
mistake was that i forgot to call the layout method when i switch the
viewer :(

the loop exception is fired by another, yet unknown, error in my code.

Finally now it works very fine.

Thank you for your help. :-)

regards Matthias
