iOS Question Canvas on RootPanel

[stevel05]

The installation of B4i went smoothly thank you for the tutorials @Erel, they made it straight froward to get it installed and working.

My first question is that is does not appear possible to draw on a canvas attached to the RootPanel, there are no errors, the drawings just don't appear. I can add a panel to it and draw on a canvas attached to that. Is this by design?

It's not a problem, just a question to help with understanding the RootPanel.

There will be a tutorial about Canvas.

You can draw on the RootPanel. However you need to recreate the canvas each time the page is resized:

Sub Page1_Resize (...)
 Canvas.Release 'first release the old object if there is one
 Canvas.Initialize(Page1.RootPanel)
End Sub

That makes sense and works, thank you.
