The HandleExpression command returns a nested data structure, which encapsulates the context menu structure displayed by this context menu module when the expression expr is right-clicked. The expr parameter can be any Maple object, including an expression sequence.

The HandleExpression command returns output in a specialized form used by Maple for generating its context-sensitive menus.  A simplified version of this output, more suitable for use in testing, is available from the command ContextMenu[Test][GetGeneratedMenu].

The command ContextMenu[CurrentContext][HandleExpression]([expr], isfullexpr) is equivalent to ContextMenu([expr], isfullexpr).

with(ContextMenu);

newCM := New():

Note the generated context-sensitive menu for newCM is empty because no entries have been added yet.

newCM:-HandleExpression(["test"], true);

Following is the result of the built-in context menu module upon on the selected object false.

CurrentContext:-HandleExpression([false], true);
