tk variables

[csjasnoch]

Is it possible to initialize the tk variables so the effect is shown in
say buttons.

For example a checkbox:

check1 = TkVariable.new
TkCheckButton.new(buttonFrm){
variable check1
command active1ButtonChecked
}.pack('side'=>'left')

The idea is I want it to open as my file states it should... So I have
a string
0:0:0:1:0:1:0:0:0


so if these were some check box variables when the program starts there
is read and I want to initialize the 4th and 6th check box to
"checked" and the rest unchecked.

I also want to be able to do this with buttons with image binded.

Thank you for you help.

I am able to handle the button image as I had already created a method
to handle this. Now I just do a call to this durring initialize (after
my file has been read)... however I can't find away to configure check
boxes.

TkVariable.new accepts an initial value.
For example,
-------------------------------------------------
buttonFrm = TkFrame.new.pack
s = '0:0:0:1:0:1:0:0:0:1:0:0'
v_list = []
s.split(':').each_with_index{|val, idx|
v_list << (v = TkVariable.new(val))
TkCheckButton.new(buttonFrm, :variable=>v,
:text=>"state #{idx}").packanchor=>:w, :fill=>:x)
}
-------------------------------------------------

I also want to be able to do this with buttons with image binded.

Please use 'image', 'selectimage' and 'indicatoron' option of
checkbutton widgets.
