[ruby][gtk2] Style Property - How to change?


Posted by Robux Biz (robux) on 05.06.2010 19:39
Hi everybody!

I can see style property:

btn = Gtk::Button.new
puts btn.style_get_property('image-spacing') # "2"

But how can I change the value to "0"?

I did that:
Code:
   class ClsBtn < Gtk::Button
     type_register
         install_style_property(GLib::Param::Int.new('image-spacing',
         'image-spacing', '', 0, 10000, 0,
         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 becames "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)

I did that:

Code:
  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
