For example, if you want to change the text of the button created above you might in Tcl do:.
The Tk documentation activeeprl be found here:. This example loads the “Tktable” package in order to make the table command available for createing table widgets:. We’ll make the application window contain a single button which will shut down the application if clicked.
We create a button with the name “. For example, in this case:. I am new to Perl scripting.
Next we will be taking a look at how to manipulate user input via the command prompt. We start out as all proper Perl programs should by enabling warnings and stricture at line 1 and 3.
PERL – Programming
Then, we load Tkx which will tutoriwl our main application window at line 4. The code to make this happen is:. In some cases the “synopsis” section describing the package will spell out the package name, but in cases like this we have found no better way than to look into the pkgIndex. The rest of the method name is the name of the Tk widget to create; i.
For example, in this case: By loading the Tkx module, we make the Tkx:: Next, we instantiate a new Tkx:: Clicking the button will invoke the subroutine registered with the button’s -command option.
Enabling PerlScript any other zones tutogial not recommended. We’ll have our script print to the command prompt with the print function just as we would if we were printing text to our web browser.
Arguments are sctiveperl as before. Enter Command or cmd into the display box. One source of confusion here is the adtiveperl spelling of the package name to provide to Tkx:: What’s the difference between ActivePerl and StrawberryPerl?

What happens is that Tkx invoked the “tk messageBox” command, but the Tcl “tk” command only takes the subcommands listed in the error message above and refuse to do anything about “messageBox”. A simple Google search yields several million results. Let’s look at what this code is doing. ActivePERL is the simplest of installers available and it is also free to download.
