I'm fairly new to FlowChartX (in fact, I'm still using the evaluation version), so the answer to this might be obvious, but I can't figure it out.

What is the proper order in which to create a series of tables, arrange them using a tree layout, and add them to a container box?

When I do the above in exactly that order, the tree layout gets squished such that the boxes are positioned in a vertical column. If I add them to a box before arranging them, though, most of them are positioned outside the box.

In both of these cases, the box ends up just being a rectangle slightly larger than the width of one of the tables. The only difference is whether or not the tables' final positions are inside or outside of the box.

Ideally, I'd like the tables to be arranged in a tree layout and the box to completely enclose them, AND for the box to resize itself to fit tables as they're moved around. Is this supported?

Second issue: I'm having trouble handling the SelectionMoved event in Win32 ATL (yeah, I know). Other events are working fine, but when I try to add SelectionMoved to my event sink, I get an "invalid callee" error, which usually is the result of mismatched parameters. This particular function, though, has no parameters!

Great... Thank you!

Regarding SelectionMoved, it worked in our test. What we did is to create an ActiveX control using the VS ATL wizard, added an ATL dialog and a method of the control to show the dialog, and inserted FlowchartX into the dialog. We've added a MessageBox call to the SelectionMoved handler that shows correctly when selected items are moved. What's interesting is that SelectionMoved was the last event defined in the control's type library, and if ATL has some boundary bug in the buffer that contains event type information, it might not work with the last official release. This beta version adds a new event (LayoutProgress), which might not work correctly now, instead of SelectionMoved...

You could handle TableModifying and call the container's ResizeToFitChildren method from there. However the user won't be able to take the table out of the container, unless you provide some other means to do that.

I hope that helps,

Are you doing that from the TableModifying event handler? It should work without removing the table and adding it again; simply call ResizeToFit. I've tested this with boxes, and the handler looks like this:

Private Sub fcx_BoxModifying(ByVal box As FLOWCHARTLibCtl.IBoxItem, ByVal docX As Long, ByVal docY As Long, ByVal selHandle As Long, Confirm As Boolean)
	If Not box.MasterGroup Is Nothing Then
		Dim c As box
		Set c = box.MasterGroup.MainObject
		c.ResizeToFitChildren
	End If
End Sub
 

Is it when you handle TableModifying, or even without handling it? Have you set the ModificationStart property value?

Does it happens only with tables that are in a container? What Flowchart.Behavior value are you using? If you call SaveToXml and send the file to support@mindfusion.eu, we'll check what settings might be causing that.
