wxTreeCtrl, hidden root incompatible with ExpandAll() ?

ioio · Post by **ioio** » Sat Aug 18, 2007 9:57 am

I want to use a wxTreeCtrl with wxTR_HIDE_ROOT, but when tree's root is hidden, ExpandAll() runs an assertion.

So what's the matter ?
I know that a hidden root cannot be collapsed, that's just a feature isn't it ? But why is it not possible to run a full tree expansion with a hidden root ? The behaviour seems to be the same with wxTR_HIDE_ROOT, we must call AddRoot() and then add first childs to this wxTreeItemId... Why does the control doesn't manage the expansion/collapse under root lvl ?

You just need to store/get the root item (wxTreeItemId) and call ExpandAllChildren.

Hi,

This has just been patched in svn. See http://svn.wxwidgets.org/viewvc/wx/wxWi ... p?view=log

Regards,

David

This is wrong, ExpandAllChildren() gives an assertion as well on hidden root item.

Apply the patch and you'll don't get anymore the assertion.
