You'll have to provide a socket (object-reference property) in
your custom canvas if you want to manipulate another control's state
(properties) or call any of its methods. I don't believe RB windows
have a global (for the window) control list (or other iterable
container) object that you can get to. It's much like making an
outlet in ObjC/Cocoa.

I have a canvas class (AnaCanvas) that sits in a window.
I have experimented with that canvas class having a property
(windowInhabited) and that property is the window in which it lives
When the window opens (the window that contains the canvas instance
myAnaCanvas), the canvas instance windowInhabited.property is
assigned the window
Using that concept, I am able to get the width and height of the
window, when I want, within methods of the canvas class.
However, I would like to have the canvas control have access to
other window controls (in my case a static text box)
That does not seem to work.
Open Event of mainWindow
Self.myAnaCanvas. windowInhabited = Me
_________________
Some method of the AnaCanvas
Dim widthValue As Integer
widthValue = Me.windowInhabited.Width 'this works
BUT
Me.windowInhabited.staticText1.Text = "Frog"
Does NOT work.
Why?
