About Content Canvases
When building an application, one of the first steps is to create content canvases that will be displayed in the windows of your form(s). While you can assign more than one content canvas to the same window at design time, at runtime only one content canvas is displayed at one time in the window.
Creating a content canvas
There are three ways to create a content canvas in Oracle Forms:
- Layout Wizard When you use the Layout Wizard
to arrange data block items on a canvas, the Layout Wizard allows you to place
data block items on a new content canvas (which the Layout Wizard will create
for you and give a default name, such as CANVAS3).
- Layout Editor In the Layout Editor, you can
create items and boilerplate objects on a specific canvas. (If there are no
canvases in a form when you invoke the Layout Editor, Oracle Forms automatically
creates a default content canvas for you to work on.)
- Object Navigator To create a content canvas
in the Object Navigator, first you create the canvas, then you specify its
type by setting the Canvas Type property in the Property Palette.
