What is canvas view type

Question

what is canvas view type property in form?

Answer 1

A canvas is a surface--inside a window container--on which you place the interface items and boilerplate objects that end users interact with when they run the form. By default, any canvas you create at runtime is assigned to the window named WINDOW1. To explicitly associate a canvas to a specfic window, set the canvas' Window property accordingly. While you can create and delete canvases in the Object Navigator, you will use the Layout Editor to accomplish most of your canvas-related tasks.
There are five types of convases:
1-Content
This is default canvas when we create form. It Specifies that the canvas should occupy the entire content area of the window to which it is assigned. Most canvases are content canvases.
2-Stacked
Specifies that the canvas should be displayed in its window at the same time as the window's content canvas. Stacked views are usually displayed programmatically and overlay some portion of the content view displayed in the same window
3-Tab
Specifies that this canvas will be a container for one or more tab pages.
4-Vertical Toolbar
Specifies that the canvas should be displayed as a vertical toolbar under the menu bar of the window. You can define iconic buttons, pop-lists, and other items on the toolbar as desired.
5-Horizontal Toolbar
Specifies that the canvas should be displayed as a horizontal toolbar at the left side of the window to which it is assigned.
