I am a novice, I work with simulations and I use VW7.2.

At the canvas I have the labels, action buttons, input fields etc. But
I wish to draw the model with squares, circles, and arows between. How
shal I do that on the GUI.
Where can I read to learn about this.

Hi Bjorn,
I'm not quite sure if this is what you need, but it may be
worth taking a look at Hotdraw (a 2D framework; it comes with some
examples). You can find it via the Parcel Manager, in the Graphics folder.

Best,
Andrés

Have a look at chapter 11 of the AppDevGuide which helps you to use
these elements and other on a graphic context in a View.

Hot Draw is great if you want your manipulated rectangles to be
dialogboxes created with the painter tool, but it is a different level
of graphical usage.

Thank you Andre's and maarten.

I learned to use to make an arrowhead and AppDevGuide to make laines
and circles. I also use the button for Region to make squares and
circles, and the button for divider to make lines. There should have
been a button for an arrowhead. I will make one.
