Could somebody provide a beginners TCL/TK example please -- HJH
Launch pad for launching external programs or other TCL scripts
Variant 1) A row with three buttons. When a button is pressed a commandline string defined at the beginning of the program is executed.
The following script is incompete, but a start.
frame .launchpad
button .launchpad.button1 -text "Data files" -command {exec command.com /c explorer "C:\\data" &}
pack .launchpad.button1 -side top -fill x
button .launchpad.button2 -text "notepad test.txt" -command {exec command.com /c notepad.exe myToDoList.txt &}
pack .launchpad.button2 -side top -fill x
button .launchpad.button3 -text "the third button"
pack .launchpad.button3 -side top -fill x
pack .launchpad -side top
console hide
____ Note: To launch an external program the command
exec myProg.exe arg1 arg2 &
is used.
Question1: How do I later assign an exec command to a button? How can I dynamically change the behaviour of buttons?
Question2: Which properties do I have to set that the buttons occupy the whole window width? -fill x is obviously not sufficient.
