Description
Tutorial - Using the Canvas Package
List of Commands in the Canvas Package
Compatibility
A "canvas" is both (1) a document template where math can be inserted and acted upon by button clicks within Maple, and (2) the document environment used by Maple Learn.
The DocumentTools:-Canvas package builds on DocumentTools component primitives to provide a way to generate such a canvas.
The NewCanvas and ShowCanvas commands can be used to construct and display math and text content organized in a grid layout. When a ScriptButton is present, additional controls and blank entry boxes are available for user input. Using Script actions the math and text can be modified and/or annotated.
In scenario (1), the canvas is viewed and interacted with directly inside a Maple document. In scenario (2), the ShareCanvas command is used to send the canvas to Maple Learn, where it can be viewed and interacted with inside a web browser.
