Hello.
I add a tree view custom gui in a dialog.
Is there any option to initialize the tree as unfolded ?
Thank you!

The folded state is define by the IsOpen function.
Simply make return to false for the first time, then after get the obj.GetBit(c4d.BIT_OFOLD)
And in your Open function which is trigger when something is open/closed
make something like
if onoff:
obj.SetBit(c4d.BIT_OFOLD)
else:
obj.DelBit(c4d.BIT_OFOLD)
Of course this method work for any BaseList2D but for any customDataType simply make a Bool member variable who gonna store the state of the folding.
Additionnaly I really suggest you to read thoses following blog post about tree view

Hi,
basically you define yourself the fold state of every node in the tree view by the return value of TreeViewFunctions::IsOpened(). Its counterpart is TreeViewFunctions::Open(), which requests to fold or unfold a certain node. It's on you to work with these. For example always returning true from IsOpened() will result in an unfolded and unfoldable tree.
And then there are TreeViewCustomGui::MakeVisible() and TreeViewCustomGui::ShowObject(), which make use of above functions to reveal a certain node in the tree.
