TCL TK .button instate pressed

[xiaocubbb]

Hi,

I wanna use .button instate pressed. But there are errors.

Here is my code:

proc displayAmtFn {} {
if {.f.b1 instate pressed == 1} {
set ::finalamt 1}
elseif {.f.b2 instate pressed == 1} {
set ::finalamt 2}
set ::finalamt ""
}

b1 and b2 are my buttons. is my syntax wrong?

my errors: invalid character "."
in expression ".f.b1 instate pressed =..."
invalid character "."
in expression ".f.b1 instate pressed =..."
(parsing expression ".f.b1 instate pressed ...")

Well, there's lots of things wrong and not just with the syntax. I'm still on ver 8.4.5 so I could be wrong but I don't know of any button function called "instate". There is a "state" option that can be queried with the "cget" function but the only states are "normal", "active", and "disabled".

If there were an "instate" function you would have needed to invoke it as a command, if [red][[/red].f.b1 instate pressed[red]][/red], but as I say, I know of no such function
