MDI Container visually linking 2 forms

[Grofit]

Hey,

Not sure if this is a simple thing and there is a way to do this automatically, or if i would have to do a botch paint to the MDI area, anyway...

I have an MDI container and within there i have 2 forms, one containing a list of images and one containing a preview of that image textured onto another object. Anyway as the images are related to the form with the preview in i was wondering if there was a simple way of drawing a line between them to visually show they are linked? A bit like when you draw an ERD or whatever diagram you want with boxes and lines, but i want each box to be a form

you can do it in just one form with a splitter

Hey,

Yeah i know i can split a form, but i want them to be in seperate forms.

Its along the same lines as a content pipeline sort of app, so you have multiple parts that can be moved around the screen that show different info but all need to be linked to each other so people can see what part effects what.

Hence why i thought i would draw a line between them...

Something like the diagram thing in this, but with forms...
