### 14`` Frame

interface frame:basic<%> : interface?
implements: | frame%

Classes matching this interface support the basic frame% functionality required by the framework.

> > method (send a-frame:basic get-area-container%)
> > → (implementation?/c area-container<%>)

> The class that this method returns is used to create the area-container<%> in this frame.

> > method (send a-frame:basic get-area-container)
> > → (is-a?/c area-container<%>)

> This returns the main area-container<%> in the frame

> > method (send a-frame:basic get-menu-bar%) → (subclass?/c menu-bar%)

> The result of this method is used to create the initial menu bar for this frame.

> Return menu-bar%.

> > > method
> > > (send a-frame:basic make-root-area-container |  | class |
> > > |  | parent) |
> > → (is-a?/c area-container<%>)
> > class : (implementation?/c area-container<%>)
> > parent : (is-a?/c area-container<%>)

> Override this method to insert a panel in between the panel used by the clients of this frame and the frame itself. For example, to insert a status line panel override this method with something like this:

> > (class ...
> > ...
> > (define status-panel #f)
> > (define/override (make-root-area-container cls parent)
> > (set! status-panel
> > (super make-root-area-container vertical-pane% parent))
> > (let ([root (make-object cls status-panel)])
> > ; ... add other children to status-panel ...
> > root))
> > ...)

> In this example, status-panel will contain a root panel for the other classes, and whatever panels are needed to display status information.

> The searching frame is implemented using this method.

> Calls make-object with class and parent.

> > method (send a-frame:basic close) → void?

> This method closes the frame by calling the can-close?, on-close, and show methods.

> It’s implementation is:

> > (inherit can-close? on-close)
> > (public
> > [show
> > (lambda ()
> > (when (can-close?)
> > (on-close)
> > (show #f)))])

> > method (send a-frame:basic editing-this-file? filename) → boolean?
> > filename : path?

> Indicates if this frame contains this buffer (and can edit that file).

> Returns #f.

> > method (send a-frame:basic get-filename [temp]) → (or/c #f path?)
> > temp : (or/c #f (box boolean?)) = #f

> This returns the filename that the frame is currently being saved as, or #f if there is no appropriate filename.

> Returns #f by default.

> If temp is a box, it is filled with #t or #f, depending if the filename is a temporary filename.

> > method (send a-frame:basic make-visible filename) → void?
> > filename : string?

> Makes the file named by filename visible (intended for use with tabbed editing).

mixin frame:basic-mixin : (class? . -> . class?)
argument extends/implements: | frame%
result implements: | frame:basic<%>

This mixin provides the basic functionality that the framework expects. It helps manage the list of frames in the group:% object returned by group:get-the-frame-group.
Do not give panel% or control<%> objects this frame as parent. Instead, use the result of the get-area-container method.
This mixin also creates a menu bar for the frame, as the frame is initialized. It uses the class returned by get-menu-bar%. It only passes the frame as an initialization argument. In addition, it creates the windows menu in the menu bar.
This mixin calls its accept-drop-files with #t.
It also calls its set-icon method according to the current value of frame:current-icon.
See also frame:reorder-menus.

> > method (send a-frame:basic show on?) → void?
> > on? : boolean?

> Overrides show in top-level-window<%>.
> Calls the super method.

> When on? is #t, inserts the frame into the frame group and when it is #f, removes the frame from the group.

> > method (send a-frame:basic can-exit?) → boolean?

> Overrides can-exit? in top-level-window<%>.
> This, together with on-exit mimics exit:exit.

> First, it calls exit:set-exiting with #t. Then, it calls exit:can-exit?. If it returns #t, so does this method. If it returns #f, this method calls exit:set-exiting with #f.

> > method (send a-frame:basic on-exit) → void?

> Overrides on-exit in top-level-window<%>.
> Together with can-exit? this mimics the behavior of exit:exit.

> Calls exit:on-exit and then queues a callback to call Racket’s exit function. If that returns, it calls exit:set-exiting to reset that flag to #f.

> > method (send a-frame:basic on-superwindow-show shown?) → void?
> > shown? : any/c

> Overrides on-superwindow-show in window<%>.
> Notifies the result of (group:get-the-frame-group) that a frame has been shown, by calling the frame-shown/hidden method.

> > method (send a-frame:basic on-drop-file pathname) → void?
> > pathname : string?

> Overrides on-drop-file in window<%>.
> Calls handler:edit-file with pathname as an argument.

> > method (send a-frame:basic after-new-child) → void?

> Overrides after-new-child in area-container<%>.
> Raises an exception if attempting to add a child to this frame (except if using the make-root-area-container method).

interface frame:focus-table<%> : interface?
implements: | top-level-window<%>

mixin frame:focus-table-mixin : (class? . -> . class?)
argument extends/implements: | frame%
result implements: | frame:focus-table<%>

Instances of classes returned from this mixin track how frontmost they are based on calls made to methods at the Racket level, instead of using the calls made by the operating system as it tracks the focus.
See also frame:lookup-focus-table, test:use-focus-table and test:get-active-top-level-window.

> > method (send a-frame:focus-table show on?) → void?
> > on? : boolean?

> Overrides show in top-level-window<%>.
> When on? is #t, adds this frame to the front of the list of frames stored with the frame’s eventspace. When on? is #f, this method removes this frame from the list.

> See also frame:lookup-focus-table, test:use-focus-table and test:get-active-top-level-window.

> > method (send a-frame:focus-table on-close) → void?

> Augments on-close in top-level-window<%>.
> Removes this frame from the list of frames stored with the frame’s eventspace.

> See also frame:lookup-focus-table, test:use-focus-table and test:get-active-top-level-window.

interface frame:size-pref<%> : interface?
implements: | frame:basic<%>

> > method (send a-frame:size-pref adjust-size-when-monitor-setup-changes?)
> > → boolean?

> Determines if the frame’s size should be automatically adjusted when the monitors configuration changes.

> Defaults to returning #f.

mixin frame:size-pref-mixin : (class? . -> . class?)
argument extends/implements: | frame:basic<%>
result implements: | frame:size-pref<%>

> > height : (or/c dimension-integer? #f) = #f
> > x : (or/c position-integer? #f) = #f
> > y : (or/c position-integer? #f) = #f

> The size-preferences-key symbol is used with preferences:get and preferences:set to track the current size.

> If present, the position-preferences-key symbol is used with preferences:get and preferences:set to track the current position.

> Both preferences are tracked on a per-monitor-configuration basis. That is, the preference value saved is a mapping from the current monitor configuration (derived from the results of get-display-count, get-display-left-top-inset, and get-display-size).

> Passes the x, y, and width and height initialization arguments to the superclass and calls maximize based on the current values of the preferences.

> See also frame:setup-size-pref.

> > > |  | height) |  | → |  | void?

> Overrides on-size in window<%>.
> Updates the preferences, according to the width and height. The preferences key is the one passed to the initialization argument of the class.

> > > method
> > > (send a-frame:size-pref on-move |  | width |  |  |  |
> > > |  | height) |  | → |  | void?
> > width : position-integer?
> > height : position-integer?

> Overrides on-move in window<%>.
> Updates the preferences according to the width and height, if position-preferences-key is not #f, using it as the preferences key.

interface frame:register-group<%> : interface?

Frames that implement this interface are registered with the group. See group:get-the-frame-group and frame:register-group-mixin.

mixin frame:register-group-mixin : (class? . -> . class?)
argument extends/implements: | frame:basic<%>
result implements: | frame:register-group<%>

During initialization, calls insert-framewith this.

> > method (send a-frame:register-group can-close?) → boolean?

> Augments can-close? in top-level-window<%>.
> Calls the inner method, with a default of #t. If that returns #t, it checks for one of the these three conditions:

> - exit:exiting? returns #t

> - there is more than one frame in the group returned by group:get-the-frame-group, or

> - the procedure exit:user-oks-exit returns #t.

> If any of those conditions hold, the method returns #t.

> > method (send a-frame:register-group on-close) → void?

> Augments on-close in top-level-window<%>.
> First calls the inner method. Next, calls the remove-frame method of the result of group:get-the-frame-group with this as an argument. Finally, unless exit:exiting? returns #t, and if there are no more frames open, it calls exit:exit.

> > method (send a-frame:register-group on-activate on?) → void?
> > on? : boolean?

> Overrides on-activate in top-level-window<%>.
> Calls set-active-frame with this when on? is true.

interface frame:status-line<%> : interface?
implements: | frame:basic<%>

The mixin that implements this interface provides an interface to a set of status lines at the bottom of this frame.
Each status line must be opened with open-status-line before any messages are shown in the status line and once close-status-line is called, no more messages may be displayed, unless the status line is re-opened.
The screen space for status lines is not created until update-status-line is called with a string. Additionally, the screen space for one status line is re-used when by another status line when the first passes #f to update-status-line. In this manner, the status line frame avoids opening too many status lines and avoids flashing the status lines open and closed too often.

> > method (send a-frame:status-line open-status-line id) → void?
> > id : symbol?

> Creates a new status line identified by the symbol argument. The line will not appear in the frame until a message is put into it, via update-status-line.

> > method (send a-frame:status-line close-status-line id) → void?
> > id : symbol?

> Closes the status line id.

> > > method
> > > (send a-frame:status-line update-status-line |  | id |  |  |  |
> > > |  | status) |  | → |  | void?
> > id : symbol?
> > status : (or/c #f string?)

> Updates the status line named by id with status. If status is #f, the status line is becomes blank (and may be used by other ids).

mixin frame:status-line-mixin : (class? . -> . class?)
argument extends/implements: | frame:basic<%>
result implements: | frame:status-line<%>

> > > method
> > > (send a-frame:status-line make-root-area-container |  | class |
> > > |  | parent) |
> > → (is-a?/c panel%)
> > class : (subclass?/c panel%)
> > parent : (is-a?/c panel%)

> Overrides make-root-area-container in frame:basic<%>.
> Adds a panel at the bottom of the frame to hold the status lines.

interface frame:info<%> : interface?
implements: | frame:basic<%>

Frames matching this interface support a status line.
The preference 'framework:show-status-line controls the visibility of the status line. If it is #t, the status line is visible and if it is #f, the status line is not visible (see preferences:get for more info about preferences)

> > > method
> > > (send a-frame:info determine-width |  | str |  |  |  |
> > > |  | canvas |  |  |  |
> > > |  | text) |  | → |  | integer
> > str : string
> > canvas : (is-a?/c editor-canvas%)
> > text : (is-a?/c text%)

> This method is used to calculate the size of an editor-canvas% with a particular set of characters in it. It is used to calculate the sizes of the edits in the status line.

> > method (send a-frame:info lock-status-changed) → void?

> This method is called when the lock status of the editor<%> changes.

> Updates the lock icon in the status line panel.

> > method (send a-frame:info update-info) → void?

> This method updates all of the information in the panel.

> > method (send a-frame:info set-info-canvas canvas) → void?
> > canvas : (or/c (is-a?/c canvas:basic%) #f)

> Sets this canvas to be the canvas that the info frame shows info about. The on-focus and set-editor methods call this method to ensure that the info canvas is set correctly.

> > method (send a-frame:info get-info-canvas)
> > → (or/c (is-a?/c canvas:basic%) #f)

> Returns the canvas that the frame:info<%> currently shows info about. See also set-info-canvas

> > method (send a-frame:info get-info-editor)
> > → (or/c #f (is-a?/c editor<%>))

> Override this method to specify the editor that the status line contains information about.

> Returns the result of get-editor.

> > method (send a-frame:info get-info-panel)
> > → (is-a?/c horizontal-panel%)

> This method returns the panel where the information about this editor is displayed.

> > method (send a-frame:info show-info) → void?

> Shows the info panel.

> See also is-info-hidden?.

> > method (send a-frame:info hide-info) → void?

> Hides the info panel.

> See also is-info-hidden?.

> > method (send a-frame:info is-info-hidden?) → boolean?

> Result indicates if the show info panel has been explicitly hidden with hide-info.

> If this method returns #t and (preferences:get 'framework:show-status-line) is #f, then the info panel will not be visible. Otherwise, it is visible.

mixin frame:info-mixin : (class? . -> . class?)
argument extends/implements: | frame:basic<%>
result implements: | frame:info<%>

This mixin provides support for displaying various info in the status line of the frame.
The result of this mixin uses the same initialization arguments as the mixin’s argument.

Initializes a preference for the frame:size-pref mixin.

The first argument should be the preferences symbol, and the second and third should be the default width and height, respectively. If the window should be maximized by default, pass #t for the maximized? argument.

If position-preferences-sym is passed, then that symbol will be used to track the position of the window.

Inserts three menu items into menu, one that inserts a text box, one that inserts a pasteboard box, and one that inserts an image into the currently focused editor (if there is one). Uses menu-item% as the class for the menu items.

Calls func right after inserting each menu item.

> procedure (frame:reorder-menus frame) → void?
> frame : (is-a?/c frame%)

Re-orders the menus in a frame. It moves the “File” and “Edit” menus to the front of the menubar and moves the “Windows” and “Help” menus to the end of the menubar.

This is useful in conjunction with the frame classes. After instantiating the class and adding ones own menus, the menus will be mis-ordered. This function fixes them up.

> procedure (frame:remove-empty-menus frame) → void?
> frame : (is-a?/c frame%)

Removes empty menus in a frame.

> (is-a?/c bitmap%)))

The value of this parameter is used by the initialization code of frame:basic-mixin.

- If it is #f, then its value is ignored.

- If it is a bitmap%, then the set-icon is called with the bitmap, the result of invoking the bitmap% get-loaded-mask method, and 'both.

- If it is a pair of bitmaps, then the set-icon method is invoked twice, once with each bitmap in the pair. The first bitmap is passed (along with the result of its bitmap% get-loaded-mask) and 'small, and then the second bitmap is passed (also along with the result of its bitmap% get-loaded-mask) and 'large.

Defaults to #f.

> procedure (frame:lookup-focus-table [eventspace])
> → (listof (is-a?/c frame:focus-table<%>))
> eventspace : eventspace? = (current-eventspace)

Returns a list of the frames in eventspace, where the first element of the list is the frame with the focus.

The order and contents of the list are maintained by the methods in frame:focus-table-mixin, meaning that the OS-level callbacks that track the focus of individual frames is ignored.

See also test:use-focus-table and test:get-active-top-level-window.
