I'm wanting to change the cursor on a diagram as follows:

The user clicks a button to add a new node and a dialog pops up which they fill in. On clicking OK I want to change the cursor on the digram to cue them they're in "add" mode and allow them to click to actually add the node in their selected position on the diagram.

I've tried setting the Cursor property but it doesn't seem to work.

Thanks,

OK, that does sound useful.

Next question: is it possible to cause the diagram to enter a particular mode programmatically as follows:

My nodes will be Controls which will have a template. In the template will be various buttons, one of which I want to use to allow the user to select a link type to add. Once selected, I want to start the operation programmatically (which would add a new link to the selected node) but go into the LinkCreating "mode" which they then finish by clicking the destination node. Is this possible?

Hi Stoyan

Your suggestion of the OnMouseDown/OnMouseMove doesn't work.

If I'm to call base.OnMouseDown and base.OnMouseMove I need to pass the MouseButtonEventArgs and MouseEventArgs objects.

Those classes have internal constructors, so only the framework can create instances of them, and the base class methods fail if I pass null.

Any other ideas?

Thanks,

Craig

Thanks Stoyan

That's interesting, though it seems a little buggy. If I move the mouse quickly it goes out of the link add mode and into the Drag-select mode.

However, I've now found another way of accomplishing what I want to do so probably won't need that functionality in the end.

I'm intending on purchasing the component today.

Cheers...
