A Gtk.HeaderBar is same as the horizontal Gtk.Box, it allows to place children at the start or the end and title to be displayed. GTK+ supports Client Side Decoration hence we can use a Gtk.HeaderBar in place of the title bar. The title will be centered with respect to the width of the box. A Gtk.HeaderBar is usually located across the top of a window and should contain commonly used controls which affect the content below. They also provide access to window controls, including the close window button and window menu.
Follow below steps:
- import GTK+ 3 module.
- Create main window.
- Create HeaderBar.
- Create Button.
- Create Box.
Example:
import gi# Since a system can have multiple versions# of GTK + installed, we want to make # sure that we are importing GTK + 3.gi.require_version("Gtk", "3.0")from gi.repository import Gtk, Gio class HeaderBarWindow(Gtk.Window): def __init__(self): Gtk.Window.__init__(self, title ="GfG") self.set_border_width(10) self.set_default_size(400, 400) # Create HeaderBar. hb = Gtk.HeaderBar() hb.set_show_close_button(True) hb.props.title = "Geeks for Geeks" self.set_titlebar(hb) # Create Button button = Gtk.Button() icon = Gio.ThemedIcon(name ="mail-send-receive-symbolic") image = Gtk.Image.new_from_gicon(icon, Gtk.IconSize.BUTTON) button.add(image) hb.pack_end(button) # Create Box box = Gtk.Box(orientation = Gtk.Orientation.HORIZONTAL) Gtk.StyleContext.add_class(box.get_style_context(), "linked") button = Gtk.Button() button.add(Gtk.Arrow(Gtk.ArrowType.LEFT, Gtk.ShadowType.NONE)) box.add(button) hb.pack_start(box) self.add(Gtk.TextView()) win = HeaderBarWindow()win.connect("destroy", Gtk.main_quit)# Display the window.win.show_all()# Start the GTK + processing loopGtk.main() |
