Delphi 7 and TcxTreeView

Trying to get a node in a this Developer Express TreeView to be able to take more than 1 line so when I hit a key press like Shift Enter, it will add another line (like a CR LF)

Does anyone know how to do get this to work? I've been looking for a while now using The Custom Control flags etc, but I can't find the right combination it seems.

Any help would be greatly appreciated !

Thanks

like this?

procedure TForm1.cxTreeView1KeyDown(Sender: TObject; var Key: Word; Shift: TShiftState);
begin
if (ssShift in Shift) and (Key = VK_RETURN) and Assigned(cxTreeView1.Selected) then
if cxTreeView1.Selected.getNextSibling <> nil then
cxTreeView1.Items.Insert(cxTreeView1.Selected.getNextSibling, 'New node' )
else
cxTreeView1.Items.AddChild(cxTreeView1.Selected.Parent, 'New node' );

end;

No that simply adds a new node under the tree.. I want more than 1 line in the node..

Like it would have

->Top Node
->New Node
More of the same node
More of the same node.
->Next Node
+ Child of Next Node

TTreeView and TcxTreeView can't draw multiline nodes. You have to draw it by youself. Here is the sample:

or use the QuantumTreeView

What set of components is the QuantumTreeView in?

Be nice if they gave an example on how to implement

Geert G

actually you would add a column with a memo field
then set it to show the full text

Geert G

the quantumtreeview should have a onMeasureItem event
in this event you would give the measurements of each record

this event doesn't exist in the TTreeview and TcxTreeview

there is also a preview column
this column is put below the first line and can be multiple lines long
there really isn't any code
just set the property PreviewColumn

there is also a banded treeview, here you can have multiple columns on multiple rows
(basically no limits :) )

Geert G

do you have a quantumgrid ?

you could simulate the treeview for a limited number of levels with group and detail grids
