Style Property - How to change?

Hi everybody!

I can see style property:

btn = Gtk::Button.new
puts btn.style_get_property(‘image-spacing’) # “2”

But how can change the value?

I did that:
class ClsBtn < Gtk::Button
type_register
install_style_property(GLib::Param::Int.new(‘image-spacing’,
‘image-spacing’,
‘’, 0, 10000, 5,
GLib::Param::READABLE|GLib::Param::WRITABLE))
end
closebtn = ClsBtn.new
image = Gtk::Image.new(Gtk::Stock::CLOSE, Gtk::IconSize::MENU)
closebtn.add(image)
p closebtn.style_get_property(‘image-spacing’)
Property became “0”,
but border around image is still big (not equals 0)
How can I to decrease the button? (The button is needed for Notebook
tabs)

       '', 0, 10000, 5, 

It should read as:

‘’, 0, 10000, 0,

I have tried to play with parameter :slight_smile:

I did that:

style = closebtn.modifier_style style.xthickness = 0 style.ythickness = 0 closebtn.modify_style(style)

But fields are still exist. Any else ideas?

I find solution in Geany source code:

[CODE] label_box = Gtk::HBox.new(false, 0)
label = Gtk::Label.new(‘Page1’)
label_box.pack_start(label, false, false, 0)

btn = Gtk::Button.new
btn.relief = Gtk::RELIEF_NONE
btn.focus_on_click = false
style = btn.modifier_style
style.xthickness = 0
style.ythickness = 0
btn.modify_style(style)
btn.set_tooltip_text("Close page1")
wim,him = Gtk::IconSize.lookup(Gtk::IconSize::MENU)
btn.set_size_request(wim+2,him+2)
btn.signal_connect('clicked') do
  $notebook.remove_page($notebook.children.index(treeview))
  store.clear
  label_box.destroy
  treeview.destroy
end

image = Gtk::Image.new(Gtk::Stock::CLOSE, Gtk::IconSize::MENU)
btn.add(image)

align = Gtk::Alignment.new(1.0, 0.0, 0.0, 0.0)
align.add(btn)
label_box.pack_start(align, false, false, 0)

label_box.spacing = 3
label_box.show_all

page = $notebook.append_page(treeview, label_box)
treeview.show_all
$notebook.page = $notebook.n_pages-1 [/CODE]
