GetItemText(item) problem

[mykula91]

Hi,

I don't know where the problem is. I have an assertion error.

Code: Select all

wxTreeCtrl* myTreeCtrl = this->GenericDirCtrl1->GetTreeCtrl();

    //this->Connect(myTreeCtrl->GetId(), wxEVT_COMMAND_TREE_SEL_CHANGED, wxTreeEventHandler(newTreeFrame::OnClickItem));
    wxTreeItemId root = GenericDirCtrl1->GetRootId();
    wxMessageBox(myTreeCtrl->GetItemText(root), _("Welcome to my app"));

Can you explain what you are trying to do?
Quick look shows that you are not testing whether the id is valid before calling GetText

[mykula91]

The root has valid Id. I have a tree created using wxGenericDirCtrl. I am checking the root ID is valid and try to Get text of this root. Then appears assert "can't retrieve virtual root item".

Hi,
How did you create GenericDirCtrl? What options did you use?
Do you actually need the generic version of the control?
Also, what OS and wx version you use?

Thank you.

wxGenericDirCtrl most likely has a hidden root item. Try getting the text from the first child instead.
