For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
how to make permanent button

Posted by xramm (xramm), 4 March 2009
I am new GUIs and tried Perl/tk in HP UX environment, so I created little GUI and there are some buttons to call shell scripts, tcl, perl scripts. it is OK so far, only problem when I click on button the GUI dissapears, not remains to re-use.
code clause:

$window->title("UNIX Test World");

$window->Label(-text => "PNM ServisNET Toolbar", -font=> "Helvetica -14 bold", -
background=> "#D2B48C")->pack;

$window->Button(-text => "IDLE Users for 5 Hours! ", -command => \&action1,)->pack;



sub action1 {
 exec "/aydin/idles\n";

exec replaces the perl program with whatever program you run. But not knowing what you are doing all I can suggest is look into open() or IPC::Cmd or IPC:pen2 or IPC:pen3 or maybe Tk (which I have no experience with) has functions/methods builtin that you can use.

You may also want to run the command in backquotes - so that the result of running it gets returned into a variable which you can then process as you wish.

As Kevin says, exec replaces your existing program, so is indeed going to get rid of the GUI!

I solved my problem by replacing "exec" with "system". Thanks for your help.
