Question:1. I have created a table dynamically using a for loop in Tcl/Tk.
2. One of the columns in the table is a column of buttons
3. All the buttons call the same action proc as the each do something similar
How can I set up the buttons so that I know which was pressed in the action proc?
Answer:
Pass in a parameter to the proc that includes the button number.
Example:
proc report {value} {
puts "Pressed button $value"
}
for {set k 1} {$k < 6} {incr k} {
button .x$k -text "Button $k" -command "report $k"
pack .x$k
}
button .quit -text Exit -command exit
pack .quit
