TTree redraw issues

Hi,

It seems TTree control doesn't get properly refreshed/repainted under some conditions. (see attachments)

It is most noticable after some of tree parameters were changed - first repaint doesn't happen as it should:
a) reposition tree nodes (TTreeNodeShape->X0=...), resize form which contains TTree control
b) change tree node shape, resize form
c) zoom, change tree node shape

Previously we were used rather old TeeTree2C6Tee6. Everything worked fine for this control.

Any help would be appreciated,
Thanks in advance,
Sebastian

Hi Sebastian,

Trying to reproduce it in a as simple example as possible, here is what I get:

1. Create a new application.
2. Drop a TTree in the form, not very big.
3. Double click the Tree to get into the editor. Add a big Rectangle (TTreeNodeShape) and close the editor:

4. Resize the Tree to try to see the whole NodeShape:

So it seems that you were able to easily reproduce it, right ?
The attached screenshot looks corrupted.

Thank you.

Any chances to include the fix in v2010.01 ?

Hi Sebastian,

I'm afraid it hasn't been fixed yet. I'll increment the priority to this ticket.
