Availability: Macintosh.
The FrameWork module contains classes that together provide a
framework for an interactive Macintosh application. The programmer
builds an application by creating subclasses that override various
methods of the bases classes, thereby implementing the functionality
wanted. Overriding functionality can often be done on various
different levels, i.e. to handle clicks in a single dialog window in a
non-standard way it is not necessary to override the complete event
handling.
The FrameWork is still very much work-in-progress, and the
documentation describes only the most important functionality, and not
in the most logical manner at that. Examine the source or the examples
for more details.
The FrameWork module defines the following functions:
- Application ()
-
An object representing the complete application. See below for a
description of the methods. The default __init__() routine
creates an empty window dictionary and a menu bar with an apple menu.
- MenuBar ()
-
An object representing the menubar. This object is usually not created
by the user.
- Menu (bar, title[, after])
-
An object representing a menu. Upon creation you pass the
MenuBar the menu appears in, the title string and a
position (1-based) after where the menu should appear (default:
at the end).
- MenuItem (menu, title[, shortcut, callback])
-
Create a menu item object. The arguments are the menu to crate the
item it, the item title string and optionally the keyboard shortcut
and a callback routine. The callback is called with the arguments
menu-id, item number within menu (1-based), current front window and
the event record.
In stead of a callable object the callback can also be a string. In
this case menu selection causes the lookup of a method in the topmost
window and the application. The method name is the callback string
with 'domenu_' prepended.
Calling the MenuBar fixmenudimstate() method sets the
correct dimming for all menu items based on the current front window.
- Separator (menu)
-
Add a separator to the end of a menu.
- SubMenu (menu, label)
-
Create a submenu named label under menu menu. The menu
object is returned.
- Window (parent)
-
Creates a (modeless) window. Parent is the application object to
which the window belongs. The window is not displayed until later.
- DialogWindow (parent)
-
Creates a modeless dialog window.
- windowbounds (width, height)
-
Return a (left, top, right, bottom)tuple suitable for creation of a window of given width and height. The
window will be staggered with respect to previous windows, and an
attempt is made to keep the whole window on-screen. The window will
however always be exact the size given, so parts may be offscreen.
- setwatchcursor ()
-
Set the mouse cursor to a watch.
- setarrowcursor ()
-
Set the mouse cursor to an arrow.
