This interface is the result of the drracket:frame:basics-mixin

method

(send a-drracket:frame: add-show-menu-items show-menu)  void?

  show-menu : (is-a?/c menu%)
Specification: This method is called during the construction of the View menu. This method is intended to be overridden with the overriding methods adding other Show/Hide menu items to the View menu.

See also set-show-menu-sort-key and get-show-menu. Default implementation: Does nothing.

method

(send a-drracket:frame: set-show-menu-sort-key item    
  key)  void?
  item : (is-a?/c menu-item<%>)
  key : (and/c real? positive?)
Controls the ordering of items in the View menu.

The number determines the sorting order and where separators in the menu appear (smaller numbers first).

These are the numbers for many of the View menu items that come built-in to DrRacket:

Toolbar     

1

Split     

2

Collapse     

3

Show Definitions     

101

Show Interactions     

102

Use Horizontal Layout     

103

Show Log     

205

Show Tracing     

206

Hide Profile     

207

Show Program Contour     

301

Show Line Numbers     

302

Show Module Browser     

401

In addition, a separator is inserted for each 100. So, for example, a separator is inserted between Collapse and Show Definitions.

Note that the argument may be a rational number, effectively allowing insertion between any two menu items already in the menu. For this reason, avoid using 0, or any number is that 0 modulo 100.

method

(send a-drracket:frame: get-show-menu)  (is-a?/c menu%)

returns the View menu, for use by the update-shown method.

See also add-show-menu-items.

The method (and others) uses the word show to preserve backwards compatibility from when the menu itself was named the Show menu.

method

(send a-drracket:frame: update-shown)  void?

Specification: This method is intended to be overridden. It’s job is to update the "View" menu to match the state of the visible windows. In the case of the standard DrRacket window, it change the menu items to reflect the visibility of the definitions and interaction editor-canvas%s.

Call this method whenever the state of the show menu might need to change.

See also get-show-menu.

Default implementation: Does nothing.
