Removeall in TGListTree

ROOT
1

Hello

I’d like to remove all items in a TGlistTree
i’d believe that Removeall() method could do it but
It seems no to do it…

for example

fTGlistTree->Removeall();
gCLient->DoReDraw();

display again fTGlistTree
( so a i see the tree twice)

Any idea?

Thank a lot

Hi,

There is no method called Removeall() in TGListTree…
You can use :
TGListTree::RecursiveDeleteItem(TGListTreeItem *item, void *userData)

Cheers,

Thank a lot
I’ll try

but how to use RecursiveDeleteItem(TGListTreeItem *item, void userData)
when we want to remove all?
RecursiveDeleteItem(0,’’) ???

Hi Luc,
Something like this:

fListTree->RecursiveDeleteItem(fListTree->GetFirstItem(), fListTree->GetFirstItem()->GetUserData());
Cheers, Bertrand.

Sorry
I get same result!

fListTree->RecursiveDeleteItem(fListTree->GetFirstItem(), fListTree->GetFirstItem()->GetUserData());

seems not to empty GVListTree.
…?
Maybe a kind of method RemoveAllItems() can be usefull for next Root version?
