NAME Win32::CtrlGUI - a Module for controlling Win32 GUIs based on Win32::Setupsup SYNOPSIS use Win32::CtrlGUI my $window = Win32::CtrlGUI::wait_for_window(qr/Notepad/); $window->send_keys("!fx"); DESCRIPTION `Win32::CtrlGUI' makes it much easier to use `Win32::Setupsup' to control Win32 GUIs. It relies completely on `Win32::Setupsup' for its underlying interaction with the GUI, but it provides a very powerful and somewhat user-friendly OO interface to make things easier. There are a number of modules in the system, so a brief overview will be provided to make it easier to understand. `Win32::CtrlGUI' This module provides a set of methods for identifying and enumerating windows. `Win32::CtrlGUI::Window' `Win32::CtrlGUI::Window' objects represent GUI windows. Internally, they simply store the window handle. Stringification is overloaded to return the window text, whereas numification and numeric comparison are overloaded to operate on the handle. Friendlier versions of the methods applicable to windows are provided. Finally, a `send_keys' method is provided that uses a (IMHO) friendlier syntax (it's based on that used by WinBatch). Instead of sending the string `\\ALT+\\f\\ALT-\\x', one sends `!fx'. Instead of sending `\\RET\\', one sends `{ENTER}' or `{RET}'. Instead of sending `\\DOWN\\\\DOWN\\\\DOWN\\', one can send `{DOWN 3}'. `Win32::CtrlGUI::State' The `Win32::CtrlGUI::State' hierarchy of modules provides for a very powerful state machine system for responding to windows and executing actions as a result. If you're using `Win32::CtrlGUI' to script any sort of process, I strongly encourage you to look at the documentation in `Win32::CtrlGUI::State'. Yes, it's complicated. But so is writing your own code to deal with optional windows, sequence forking, and so forth. For now, there isn't much documentation. See the demo.pl script for some ideas, and beyond that, feel free to contact me if you have questions. Also, there is a Tk debugger now. It requires, of course, that Tk be installed. I haven't done much testing to see how it behaves on anything other than Perl 5.6.0 with Tk 800.022. Take a look at demotk.pl for an example. `Win32::CtrlGUI::Criteria' The `Win32::CtrlGUI::Criteria' hierarchy supports the `Win32::CtrlGUI::State' hierarchy by providing an OO interface to state criteria. Installation instructions `Win32::CtrlGUI' depends on `Win32::Setupsup', available from http://www.cpan.org/modules/by-module/Win32/setupsup.1.0.1.0.zip, although you might want to check that folder to see if there is a more recent version. If you want to use the Tk debugger/observer, you will need `Tk' and `Win32::API'. Both are available from CPAN and via PPM. Standard `Make::Maker' approach or just move everything in `Win32' into `site/lib/Win32'. METHODS enum_windows This method returns a list of `Win32::CtrlGUI::Window' objects representing the windows currently open. It uses `Win32::Setupsup::EnumWindows' for the underlying call. wait_for_window This method waits a for a window matching the passed criteria. It accepts three parameters - criteria for the window, criteria for the child window, and a timeout. The last two parameters are optional. If you need to specify a timeout, but don't want to specify criteria for the child window, pass `undef' as the child window criteria. Criteria can be one of three things: * A string. In this case, the string will be matched case insensitively against the window title. * A regular expression. These should be passed using the `qr/ . . . /' syntax. * A code reference (i.e. `sub { . . . }'). Code references will have access to a `Win32::CtrlGUI::Window' object in `$_' and should return true or false. These three formats can be used both for the window and the child window criteria. In the special case of a string match on the window and no child window criteria, `Win32::Setupsup::WaitForWindow' will be used. In all other cases, a busy loop is executed using the default wait interval in `$Win32::CtrlGUI::wait_intvl' (specified in milliseconds). The call will return a `Win32::CtrlGUI::Window' object if successful or `undef' if it timesout. If the timeout value is unspecified or negative, it waits indefinitely. Timeout values are specified in seconds (fractional seconds are allowed). get_windows This method returns a list of all windows matching the passed criteria. Same criteria format as for `wait_for_window'. Instead of a timeout, the third parameter is the optional justone parameter. If it is true, `get_windows' returns only the first window to match the criteria. The returned windows are, of course, `Win32::CtrlGUI::Window' objects.
