EVENT HANDLER CALLBACKS
The Aqua/Mac OS X application environment defines a number of addi-
tional events that applications should respond to. These events are
mapped by Tk to calls to commands in the ::tk::mac namespace; unless
otherwise noted, if the command is absent, no action will be taken.
::tk::mac::ShowPreferences
The default Apple Event handler for kAEShowPreferences, "pref".
The application menu "Preferences" menu item is only enabled
when this proc is defined. Typically this command is used to
wrap a specific own preferences command, which pops up a prefer-
ences window. Something like:
proc ::tk::mac::ShowPreferences {} {
setPref
}
::tk::mac::OpenApplication
If a proc of this name is defined, this proc fill fire when your
application is intially opened. It is the default Apple Event
handler for kAEOpenApplication, "oapp".
::tk::mac::ReopenApplication
If a proc of this name is defined it is the default Apple Event
handler for kAEReopenApplication, "rapp", the Apple Event sent
when your application is opened when it is already running (e.g.
by clicking its icon in the Dock). Here is a sample that raises
a minimized window when the Dock icon is clicked:
proc ::tk::mac::ReopenApplication {} {
if {[wm state .] eq "withdrawn"} {
wm state . normal
} else {
wm deiconify .
}
raise .
}
::tk::mac::OpenDocument file...
If a proc of this name is defined it is the default Apple Event
handler for kAEOpenDocuments, "odoc", the Apple Event sent when
your application is asked to open one or more documents (e.g.,
by drag & drop onto the app or by opening a document of a type
associated to the app). The proc should take as arguments paths
to the files to be opened, like so:
proc ::tk::mac::OpenDocument {args} {
foreach f $args {my_open_document $f}
}
::tk::mac::PrintDocument file...
If a proc of this name is defined it is the default Apple Event
handler for kAEPrintDocuments, "pdoc", the Apple Event sent when
your application is asked to print one or more documents (e.g.,
via the Print menu item in the Finder). It works the same way
as tk::mac::OpenDocument in terms of arguments.
::tk::mac::Quit
If a proc of this name is defined it is the default Apple Event
handler for kAEQuitApplication, "quit", the Apple Event sent
when your application is asked to be quit, e.g. via the quit
menu item in the application menu, the quit menu item in the
Dock menu, or during a logout/restart/shutdown etc. If this is
not defined, exit is called instead.
::tk::mac::OnHide
If defined, this is called when your application receives a
kEventAppHidden event, e.g. via the hide menu item in the appli-
cation or Dock menus.
::tk::mac::OnShow
If defined, this is called when your application receives a
kEventAppShown event, e.g. via the show all menu item in the
application menu, or by clicking the Dock icon of a hidden
application.
::tk::mac::ShowHelp
Customizes behavior of Apple Help menu; if this procedure is not
defined, the platform-specific standard Help menu item "YourApp
Help" performs the default Cocoa action of showing the Help Book
configured in the application's Info.plist (or displaying an
alert if no Help Book is set).
ADDITIONAL DIALOGS
The Aqua/Mac OS X defines additional dialogs that applications should
support.
::tk::mac::standardAboutPanel
Brings the standard Cocoa about panel to the front, with all its
information filled in from your application bundle files (stan-
dard about panel with no options specified). See Apple Technote
TN2179 and the AppKit documentation for -[NSApplication order-
FrontStandardAboutPanelWithOptions:] for details on the
Info.plist keys and app bundle files used by the about panel.
SYSTEM CONFIGURATION
There are a number of additional global configuration options that con-
trol the details of how Tk renders by default.
::tk::mac::useCompatibilityMetrics boolean
Preserves compatibility with older Tk/Aqua metrics; set to false
for more native spacing.
::tk::mac::CGAntialiasLimit limit
Sets the antialiasing limit; lines thinner that limit pixels
will not be antialiased. Integer, set to 0 by default, making
all lines be antialiased.
::tk::mac::antialiasedtext number
Sets anti-aliased text. Controls text antialiasing, possible
values for number are -1 (default, use system default for text
AA), 0 (no text AA), 1 (use text AA).
::tk::mac::useThemedToplevel boolean
Sets toplevel windows to draw with the modern grayish/ pinstripe
Mac background. Equivalent to configuring the toplevel with
"-background systemWindowHeaderBackground", or to using a
ttk::frame.
SUPPORT COMMANDS
::tk::mac::iconBitmap name width height -kind value
Renders native icons and bitmaps in Tk applications (including
any image file readable by NSImage). A native bitmap name is
interpreted as follows (in order):
o predefined builtin 32x32 icon name (stop, caution, document,
etc.)
o name, as defined by tk::mac::iconBitmap
o NSImage named image name
o NSImage url string
o 4-char OSType of IconServices icon
The width and height arguments to tk::mac::iconBitmap define the
dimensions of the image to create, and -kind must be one of:
-file icon of file at given path
-fileType
icon of given file type
-osType
icon of given 4-char OSType file type
-systemType
icon for given IconServices 4-char OSType
-namedImage
named NSImage for given name
-imageFile
image at given path
