Treeview change text of node before node is in an editable state

Question

How do I change text of treeview node(by "long click" of mouse) before node is in an editable state(user can rename the label text) without overriding "OnNotifyMessage"?

Answer 1

please specify which programming language you are using?

And what is the project type? From your description, I think the question is not about Win32 application.

If you are working with a C# windows Forms application, please move to Visual C# General forum.

If it is CLR windows Forms application, please try Common Language Runtime CLR forum.

The proposed answer seem to work only for the situation where the mouse right click is involved. I need the solution for the "long left click" where the node turns to an editable state with the text already changed to some preset name. Thank you.

Actually i didn't understand what is your requirement. If you want to change the text of TreeView when you click on it then see the following sample. I am not sure you need this

void TreeCtrlEx::OnLButtonUp(UINT nFlags, CPoint point)
{
	HTREEITEM hTree = GetSelectedItem();
	SetItemText(hTree,_T("hellow"));
	EditLabel(hTree);
	CTreeCtrl::OnLButtonUp(nFlags, point);
}

Hi Renjith,

Thanks for your reply.

I want the node to be in an editable state i.e for renaming. This is somewhat like renaming a folder/file which is already selected and then clicking on the folder name with the left click holding the button down for some amount of time. 

Answer 8

Could you please elaborate your question. I understood that

You have a TreeView and you click( right or left) on one item. That item need to be in editable state. This can be done using the same code in my last post. Only the mouse handler will be changed respective to right or left button of mouse. Also remove SetItemText() call.

void TreeCtrlEx::OnLButtonUp(UINT nFlags, CPoint point)
{
	HTREEITEM hTree = GetSelectedItem();
	EditLabel(hTree);
	CTreeCtrl::OnLButtonUp(nFlags, point);
}

void TreeCtrlEx::OnRButtonUp(UINT nFlags, CPoint point)
{
	HTREEITEM hTree = GetSelectedItem();
	EditLabel(hTree);
	CTreeCtrl::OnLButtonUp(nFlags, point);
}

if you want edit on mouse button down, try HitTest() inside the mouse handlers.
