Hello folks,

i have two "little" problems with selecting of nodes:

===

(A) when the user clicks around with ctrl-key pressed, he can add nodes to selection.
The shift-key does not do anything similar (like adding the span in between to selection), so i tried to do it programmatically.

Adding per
diag.Selection.AddItem(node);

does set the node as ActiveItem, but it does not get marked as part of selection (added) like it would per manual ctrl-click?

====

(B) Also, how does one disable the selection rectangle completely? I have some diagrams where selecting is disabled, so the selection rectangle does not show up on mouse drag over background, but in other diagrammes i would like to have selecting (per clicking), but not the (uncontrollable) selection rectangle.

I tried setting
ModifierKeyActions.Alt = ModifierKeyAction.Select;

in the hope that ONLY holding of ALT key would allow for select rectangle, but it happens all the same also without ALT pressed...

any suggestions please?

cheers

ah thankx Stoyan, will try that.

I also solved (A) in the meantime, as the selecting was done within the NodeSelecting handler, it was probably cleaning up the selection frames in between, so i established another list ToBeSelected in which i reselect on MouseUp:

               if (ToBeSelected.Count > 0)
               {
                   foreach (DiagramNode node in ToBeSelected)
                   {
                       node.Selected = true;
                       Selection.AddItem(node);
                   }
                   ToBeSelected.Clear();
               }

and it draws nice select frames around

Only prob is, they are ugly black and rectangular (not following the shape) so i haev to fin dout how to make them e.g. red and oblong like the shapeNode is.

- set node.HandlesStyle to Invisible and use the node's Stroke and StrokeThickness properties to indicate selection state;

thx, did that also in mouseup, adding effects as well and a stronger one for ActiveItem.

Keep on good work
