NAME
Tk::Wizard::Installer::Win32 - Win32-specific routines for Tk::Wizard::Installer
DESCRIPTION
As a sub-class of Tk::Wizard and Tk::Wizard::Installer, this module offers all of those methods and means, plus the below, which are thought to be specific to the Microsoft Windows platform.
If you are looking for a freeware software installer that is not dependant upon Perl, try Inno Setup - http://www.jrsoftware.org/
. It's so good, even Microsoft have been caught using it.
If you are looking for a means to update the Windows Path
variable, have a look for PathTool.exe, a tiny Windows 32-bit executable by Luke Bailey (luke@notts.flexeprint.com
). This tool can also be used to add new, persistant environment variables to the system.
METHODS
register_with_windows
Registers an application with Windows so that it can be "uninstalled" using the Control Panel's Add/Remove Programs dialogue.
An entry is created in the Windows' registry pointing to the uninstall script path. See UninstallString
, below.
Returns undef
on failure, 1
on success. Does nothing on non-MSWin32 platforms
Aguments are:
- uninstall_key_name
-
The name of the registery sub-key to be used. This is transparent to the end-user, but should be unique for all applications.
- UninstallString
-
The command-line to execute to uninstall the script.
According to Microsoft at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnwue/html/ch11d.asp:
"You must supply complete names for both the DisplayName and UninstallString values for your uninstall program to appear in the Add/Remove Programs utility. The path you supply to Uninstall-String must be the complete command line used to carry out your uninstall program. The command line you supply should carry out the uninstall program directly rather than from a batch file or subprocess."
The default value is:
perl -e '$args->{app_path} -u'
This default assumes you have set the argument
app_path
, and that it checks and reacts to the the command line switch-u
:package MyInstaller; use strict; use Tk::Wizard; if ($ARGV[0] =~ /^-*u$/i){ # ... Have been passed the uninstall switch: uninstall myself now ... }
Or something like that.

These are all displayed when the Support Information link is clicked in the Add/Remove Programs dialogue. The last should be full URIs.
The routine will also try to add any other parameters to the registry tree in the current location: YMMV.
addStartMenuPage
Adds a page that allows users to select a location on the Windows "Start Menu", perhaps to add a shortcut there.
This routine does not currently create the directory in the Start Menu, nor does it place a link there - see "callback_create_shortcut" for that. Rather, the caller supplies a -variable
parameter that is a reference to a scalar which, once the page is 'run', will contain either the path to the user's chosen directory, or undef
if the option to not select was chosen.
In addition, when the page is 'run', it places the path to the current user's Start Menu/Programs directory into the object field startmenu_dir_current
, and the path to the common Start Menu/Programs in the object field startmenu_dir_common
.
The physical creation of the shortcut is left as an exercise to the reader. Have a look at the $mkdir
Button
in Tk::Wizard/page_dirSelect
.
- -user
-
Set to
all
orcurrent
to list the "Start Menu" for all users, or just the current user. Default isall
. Note that in the current versions of Windows in common use, if there exist entries with the same name in both the common and current user's Start Menu, the entry in the common menu takes precedence. - -variable
-
A reference to a variable that, when the page is completed, will contain the directory the user has chosen to create an item in. Note this is not the full path: see above.
- -program_group
-
Name of the directory to create on the start menu, if any. If defined, this will be appended to any selection the user makes. Note that since addStartMenuPage() is just the GUI part, no directory will actually be created until
/callback_create_shortcut
is called. - -disable_nochoice
-
Set to prevent the display of the checkbox which allows the user not to use this feature. See
-label_nochoice
, below. - -label_nochoice
-
If the parameter
-disable_nochoice
has not been set,-label_nochoice
should contain text to use for the label by the checkbox which disables choices on this page and causes the page to set the-variable
parameter toundef
. Default text isDo not create a shortcut on the Start Menu
. - -listHeight
-
Height of the list box, default is
10
but you may vary this if your-text
attribute takes up more or less much room.
Accepts the Standard Options that are common to the HList
and Label
widgets, but does not accept aliases:
-relief -highlightthickness -background -borderwidth -cursor
-highlightcolor -foreground -font
You can supply the common Tk::Wizard options:
-title -subtitle -text
This method will initially attempt to use Win32.pm; failing that, it will attempt to use a Windows Scripting Host object created via Win32::OLE. If both fail (WSH only existing by default in Win98 and above), the routine will return undef
, rather than a page frame object. This may not be ideal but works for me -- suggestions welcomed for a better idea.
CALLBACKS
callback_create_shortcut
A convenience interface to Win32::Shortcut method that creates a shortcut at the path specified. Parameters are pretty much what you see when you right-click a shortcut:
- -save_path
-
The location at which the shortcut should be saved. This should be the full path including filename ending in
.lnk
.The filename minus extension will be visible in the shortcut. If the
-program_group
parameter was passed toMETHOD page_start_menu
, the directory it refers to will be included in the save path you supply. To avoid this, eitherundef
ine the object field-program_group
, or supply the parameter-no_program_group
. - -no_program_group>
-
See
-save_path
, above. - -target
-
The shortcut points to this file, directory, or URI -- see notes for
-save_path
, above. - -workingdir
-
The working directory for the
-target
, above. - -description
-
This is what you see when you mouse-over a shortcut in more "modern" (Win2k/ME+) Windows.
- -iconpath
-
Path to the icon file -- an
.exe
,.dll
,.ico
or other acceptable format. - -iconindex
-
Index of the icon in the file if a
.exe
or.dll
. - -arguments
-
Um... it's the second parameter in Win32::Shortcut::Set - could well be parameters for the target, but I'm too much of a rush to check. XXX
- -show
-
Whether the
-target
, above, should be started maximized or minimized. Acceptable values are the constants:SW_SHOWMAXIMIZED SW_SHOWMINNOACTIVE SW_SHOWNORMAL
- -hotkey
-
Key combination to activate the shortcut. Probably looks something like
ctrl+t
.
On success, returns the -save_path
; on failure, undef
.
callback_create_shortcuts
Convenience method to create multiple shortcuts at once. Supply an array of hashes, each hash being arguments to supply to callback_create_shortcut
.
Returns an array or reference to an array that contains the reults of the shortcut creation.
