Hidden text widget

[anirban2k2001]

Hi all,

I need to store some values in a hidden text widget which is in a frame in tcl so that I can use those values to perform some mathematical operations when I click on the submit button. My problem is that I cannot make a text widget hidden. I am giving below the text widget code which I am using. What more do I need to specify in my code so that the text widget is hidden?

Code:

frame .f2 -width 250 -height 270
pack .f2
pack propagate .f2 0

label .f2.l1 -text "Name" -font $fnt9
place .f2.l1 -x 0 -y 25

text .f2.t1 -bd 1 -highlightbackground black - highlightthickness 1 -font $fnt9
.f2.t1 insert end [string trim $nm]
.f2.t1 configure -state disabled
place .f2.t1 -x 65 -y 25 -width 170 -height 16

In the above code, $nm contains a value which is to be used for a mathematical operation. So .f2.t1 is to be made hidden.

Any help will be appreciated.
Thanks in advance.

To hide a frame, you would use "withdraw": wm withdraw .f2.t1.

However, I don't see why you have to do that. Why not just use a variable that is not displayed?

Many thanks for your response.

I tried using your code but it gives me the following error:
Error: ".f2.t1" isn't a top-level window

Regarding your query: I need to specify some hidden text widgets because I want to have access to those values when I click on the Submit button and a procedure is invoked.

If I do a puts $varname on f2 after the query, it fetches the value but when I try to access the same variable from the Submit button procedure it does not recognise the variable.

That's because the scope is wrong. Put the variables in a "global" statement in your proc. Like:

proc procName {} {
  global variable1 variable2 ...
}
