It seems like progressbar can't be disabled (however the documentation >doesn't mention this ). Isn't possible set the state of this widget ?

Maybe this is what you want?

set p [ttk::progressbar .progreso -orient horizontal -mode indeterminate]
set b [ttk::button .boton -text "Disable pb" -command "$p stop" ]
pack $b $p -fill both -expand 1
$p start 5

Also, note that the correct way of setting the state of a progress bar is
$p state disabled

You don't use -configure


So you could do this:

set p [ttk::progressbar .progreso -orient horizontal -mode indeterminate]
set b [ttk::button .boton -text "Disable pb" -command "$p state disabled; puts \"state now is [$p state disabled]\""]
pack $b $p -fill both -expand 1
puts "state is [$p state disabled]"
$p start 5


Now, what purpose this 'state' command ever serves in a progress bar is
beyond me.

Hi Luc,

actually i want to disabled it, not stop it.
Using your example, i got first

state is

and after click in the button

state now is !disabled

by the way, the progressbar remains enabled all time.

Saludos,
Alejandro

What do you mean by "disabled"?

I don't know what a disabled progress bar is.

Well, is like a disabled button ... but with progressbar.
May be this is a silly question but jokes aside, is still valid.

Except that "disabled" is an odd state to reason about for a "progress
bar".

Buttons are active items that accept user interaction (click on
button). "Disablement" for a button makes sense as it prevents
"activation" of the button until it is later enabled.

A progress bar (at least a normal one) is a "one-way" widget. It
conveys information to a user, but there is usually no "interaction"
from the user (no clicking on the bar to do something). Therefore,
with no "interaction", there is nothing to "disable", and setting it to "disabled" is an odd state to ask about.

Ok, but what about labels then ?.
You can to configure the state of labels to "disabled" or "readonly", for example.
How the user interact with a label ?
Odd?. May be. But you can disable a label if you want ...

Ok, that's fair. No interaction with a label, but it can still be
disabled.

And..., I should have consulted the docs before replying previously:

For ttk widgets, disablement is one of the "state" flags that is
controled by the 'state' sub-command, not by 'configure -state' like
with traditional Tk widgets:

$ rlwrap wish
% ttk::progressbar .pb
.pb
% .pb state
% .pb state disabled
!disabled
% .pb state
disabled
%

Read about it in the progressbar man page and the ttk::widget man page.

Disabled progress bars are sometimes used if a task has finished or is suspended. They should be shown differently to non-disabled progress bars.

Sometimes, progress bars are overlaid with an invisible slider widget. (I
don't recommend this, it's hard to get right.) Disabled would mean
disabling that invisible slider, in that case.

set a multi-line signature. Some say it should be that way. Most of those people already have us on their killfile.

Your words make sense to me, but the whole won't until someone explains
how that "disabled" state is different from a stopped progress bar.
