HitTestAdjustmentHandles

Hi Stoyan,

Is there any easy way for me to decide and enable the Resize handles since I was setting it to Move always before. Now Some items need to be resizable. (I'm using "Custom" HandleStyle)

void diagram_HitTestAdjustmentHandles(object sender, HitTestEventArgs e)
{
    if (e.Item != null && e.Item.ContainsPoint(e.MousePosition))
    {
         e.HitResult = 8;
    }
}

Thanks!

Kyle

Hi,

You could assign one of the standard styles to nodes that can be resized. If you prefer using an event handler for all nodes, you could still reuse the hit-testing code for some of the standard handle styles as shown here:

You can also compare the point coordinates with node's border and corner coordinates and set HitResult accordingly.

I hope that helps,
Stoyan
