Hi,

I have found that when I call GetNodeAt() when processing mouse moves it DOES return a node at the supplied point, but it returns the first one created, NOT the one on top!

The help says it returns the top-most node at the specified point according to the Z-order.  So my question is, when I select a node, and it moves obove the other nodes on the diagram, does this not also move it's z-order position to the top?

This problem is not only in my code, but can also be seen in the 'Class-hierarchy diagram' demo.  If you move the 'String' class node a little so that it's on a grid point, then move the 'IntList' class node exactly on top of it (so that the 'methods' expansion button is on top of the one for the 'String' class), and then click the expansion button on the 'IntList' node, the 'String' node will expand and collapse!

How can I fix this?

Thanks.

Hi Stoyan,

I have now hooked into the NodeSelected event as you suggested, and set the newly selected node to the top of the z-order (and all it's child nodes, which I'm using as buttons,  above that).  Now when one node is on top of another, I can click on the buttons and the correct node handles the clicks.

But, when I click on the expansion button in the tree, it still expands/collapses the one underneath!

This version should hit test the +/- buttons in the correct order and also fixes the AutoDeleteItems problem:

I hope that helps,

Hi Brian,

You only need to overwrite the assemblies referenced by your project with the ones from the zip file. If you get a build error that mentions LC.EXE, edit licenses.licx and set PublicKeyToken=null at the end of the Flowchart.NET entry there.
