Ruby Tk::Tile button not displaying colors

Ruby
1

I have some ruby tk code that uses the new Tile styles.

I see no difference at all, when I do this over just a regular button.
Can someone point to what might be the problem?

Here is the code:

I defined the new style Normal.TButton:

Tk::Tile::Style.configure(‘Normal.TButton’, { “background” => ‘blue’,
“foreground” => ‘white’, “padding” => 5})

Now I use it (notice the style ‘Normal.TButton’:

Tk::Tile::Button.new(content) {text lbl; command proc{docommand("%s" %
[k]); style ‘Normal.TButton’} }.grid( :column => 1, :row => (row +=
1),
:sticky => ‘w’)

But the button shows up as if I had not define/used the style.

If it makes a difference: I am running the code on a raspberry pi.And I
have ssh’d from OSX (Yosemite)

If you would like to see the entire code, I can post that. But I wanted
to
show the two lines that are pertinent to the discussion.

Thankyou in advance.

Hi Jerry D.,

It correctly changed the ‘style’ of the button with this “adapted”
code (just to make your code show up).
So, I don’t see any problem with the fragment of code you showed.

Abinoam Jr.

require ‘tk’
require ‘tkextlib/tile’

Fake values to test the lines bellow

row = 1
lbl = “fake lbl”
k = ‘text “Executed command”’

def docommand(command)
eval command
end

root = TkRoot.new { title “Jerry D.” }
content = Tk::Tile::Frame.new(root) { padding “3 3 12 12” }.grid(
:sticky => ‘nsew’)

Tk::Tile::Style.configure(‘Normal.TButton’, { “background” => ‘blue’,
“foreground” => ‘white’, “padding” => 5})
Tk::Tile::Button.new(content) {text lbl; command proc{docommand("%s" %
[k]); style ‘Normal.TButton’} }.grid( :column => 1, :row => (row +=
1), :sticky => ‘w’)

Tk.mainloop

rvm 1.26.7 (master)

Ruby build with
“rvm reinstall ruby-2.1.5 --enable-shared --enable-pthread --with-tk
–with-tcl”

Mac OS X 10.9.4

Tk::TK_PATCHLEVEL # => “8.5.9”
Tk::Tile::TILE_SPEC_VERSION_ID # => 8

I see what is happening now. The button doesn’t become background blue
and
foreground white, does not actually take effect until the button is
clicked.

What do you do to set the colors in the NORMAL (not clicked or hovered
over)? I am a newbie as far as tk goes, and am trying to understand.

The script sets TButton’s style in the callback.
Please compare the followings.

Tk::Tile::Button.new(content) {
text lbl
command proc{docommand(“%s” %[k]); style ‘Normal.TButton’}
}.grid( :column => 1, :row => (row += 1), :sticky => ‘w’)

thanks. that was a subtlety that I missed.
that helps a lot, and worked the way I wanted.

so, just one more question then before this topic ends.

how do I set the style back to Normal in the callback?
(assuming I set say $b to the button I created?

after the eval statement, I put::
$b.configure(:style => ‘Normal.TButton’)

which gave no errors but didn’t do anything either.

thanks
