12 Frame
| frame:basic<%> : interface? | ||
|
Classes matching this interface support the basic
frame%
functionality required by the framework.
(send a-frame:basic get-area-container%) → (is-a?/c area-container<%>) The class that this method returns is used to create the area-container<%> in this frame.
(send a-frame:basic get-area-container) → (instance (is-a?/c area-container<%>)) This returns the main area-container<%> in the frame
(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%.
(send a-frame:basic make-root-area-container class parent) → (instance (is-a?/c area-container<%>)) class : (is-a?/c area-container<%>) parent : (instance (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 ... ... (rename [super-make-root-area-container make-root-area-container]) (field [status-panel #f]) (define/override (make-root-area-container cls parent) (set! status-panel (super-make-root-area-container vertical-panel% 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.
It’s implementation is:
(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.This returns the filename that the frame is currently being saved as, or #f if there is no appropriate filename.Defaultly returns #f.
If temp is a box, it is filled with #t or #f, depending if the filename is a temporary filename.
(send a-frame:basic make-visible filename) → void filename : string Makes the file named by filename visible (intended for use with tabbed editing).
| frame:basic-mixin : (class? . -> . class?) | ||
| ||
|
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.
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.Overrides can-exit? in top-level-window<%>.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.Overrides on-exit in top-level-window<%>.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.
(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.
(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.
(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).
| frame:size-pref<%> : interface? | ||
|
| frame:size-pref-mixin : (class? . -> . class?) | ||
| ||
|
(new frame:size-pref-mixin [size-preferences-key size-preferences-key] [label label] [ [parent parent] [x x] [y y] [style style] [enabled enabled] [border border] [spacing spacing] [alignment alignment] [min-width min-width] [min-height min-height] [stretchable-width stretchable-width] [stretchable-height stretchable-height]]) → (is-a?/c frame:size-pref-mixin) size-preferences-key : symbol? label : label-string? parent : (or/c (is-a?/c frame%) false/c) = #f x : (or/c (integer-in -10000 10000) false/c) = #f y : (or/c (integer-in -10000 10000) false/c) = #f

See also frame:setup-size-pref.
Updates the preferences, according to the width and height. The preferences key is the one passed to the initialization argument of the class.
Frames that implement this interface are registered with the group. See
group:get-the-frame-group
and
frame:register-group-mixin.
| frame:register-group-mixin : (class? . -> . class?) | ||
| ||
|
During initialization, calls
insert-framewith this.
(send a-frame:register-group can-close?) → bool 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.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.
(send a-frame:register-group on-activate on?) → void on? : boolean? Overrides on-activate in top-level-window<%>.
| frame:status-line<%> : interface? | ||
|
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.
(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.
(send a-frame:status-line close-status-line id) → void id : symbol? Closes the status line id.
(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).

| frame:info<%> : interface? | ||
|
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)
(send a-frame:info determine-width str canvas text) → integer str : string canvas : (instance editor-canvas%) text : (instance text%) This method is used to calculate the size of an editor-canvas% with a particular set of characters in it.

(send a-frame:info set-info-canvas canvas) → void canvas : (instance canvas:basic%) 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.
(send a-frame:info get-info-canvas) → (instance canvas:basic%) Returns the canvas that the frame:info<%> currently shows info about. See also set-info-canvas
(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.
(send a-frame:info get-info-panel) → (instance horizontal-panel%) This method returns the panel where the information about this editor is displayed.Shows the info panel.See also is-info-hidden?.
Hides the info panel.See also is-info-hidden?.
(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.
| frame:info-mixin : (class? . -> . class?) | ||
| ||
|
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.

| frame:text-info<%> : interface? | ||
|
Objects matching this interface receive information from editors
constructed with
editor:info-mixin
and display it.
(send a-frame:text-info set-macro-recording on?) → void on? : boolean? Shows/hides the icon in the info bar that indicates if a macro recording is in progress.
(send a-frame:text-info overwrite-status-changed) → void This method is called when the overwrite mode is turned either on or off in the editor<%> in this frame.

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.
| (frame:reorder-menus frame) → void? |

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.

| frame : (is-a?/c frame%) |
Removes empty menus in a frame.
| ||||||||||
| (frame:current-icon icon-spec) → void? | ||||||||||
|
The value of this parameter is used by the initialization code of
frame:basic-mixin.
If it is #f, then its value is ignored.
It 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.
