Hi,
I’ve been adapting GF/ST and using the Organisational
Tree as a model.
I’ve noticed that there appears to be a bug when the
background is selected – it is getting stuck grabbing the mouse.
After a lot of poking around and infinite walkbacks, I think it the problem is that getting the rectangle
from the user somehow doesn’t let go of the mouse tracking.
Consequently once you’ve clicked on the background,
you have to select a tree node to get out of rectangle from user mode.
I was wondering if anyone has encountered this and has a fix
for it?
Cheers,
Stewart

To replicate:
Smalltalk.Polymorphic.GFOrgChartEditor open.
Select Digittalk from the list of
organisations.
If using Cairo as per Henrik
you’ll need to resize or overlay the window to display the tree (not sure
why?).
Click on tree nodes, they turn red.
Then click on background, and the system goes into “Rectangle
from user” mode.
Click on a node to exit mouse grabbing.
