right click...

I am using a treeview with a popup menu assigned to it. When i right click on the treeview the popup menu works ok but the problem is i want to be able to right click on a node, highlight it and get the node selected.index returned so that when i choose a command on the popup menu it knows what node i am working with.

any ideas?

kretzschmar

set the option rightclickselect or similar to true in the tree option propertys

Epsylon

Use the TTreeView.OnContextPopup event:

procedure TForm1.TreeView1ContextPopup(Sender: TObject; MousePos: TPoint;
var Handled: Boolean);
begin
TreeView1.Selected := TreeView1.GetNodeAt(MousePos.x, MousePos.y);
Menu1.Caption := TreeView1.GetNodeAt(MousePos.x, MousePos.y).Text;
end;

kretzschmar, i checked for a rightclickselect in the property but there isn't one.

epsylon, there is no OnContextPopup event either.

I'm using delphi 2 if that makes a difference.

kretzschmar

delphi2, yes this makes sure a difference :-)

but i guess you can use eps code in the mousedown-event,
just check the mousebutton-before

Why do people never say which version they use when they ask a question? It is trivial information.

Epsylon

I guess the GetNodeAt() method is not there eighter in D2..?

kretzschmar

don't know, eps, long time ago as i used d2

sorry epsylon - it's late here and sleep has been knocking on the door for hours but i have tried to ignore it to get a few bugs in my program sorted out.

i have arranged to have myself smacked around the head with a wet lettuce at a leter date as punishment for not giving the version number in the original question.

the good news of course is that the code you gave me seems to have worked when i put it into the mousedown event and changed the code to:

TreeView1.Selected := TreeView1.GetNodeAt(x, y);
label1.Caption := TreeView1.GetNodeAt(x, y).Text;

one thing though, what does the MousePos do and am losing something by removing it?

>one thing though, what does the MousePos do and am losing something by removing it?
what mousepos?

if you mean x,y you need it only to select the rightclicked node, maybe you should check, if a node if afterwards really selected

TreeView1.Selected := TreeView1.GetNodeAt(x, y);
if assigned(TreeView1.Selected) then
label1.Caption := TreeView1.selected.Text;

kretzschmar
