嵌入GTK3

演示使用通过pygobject访问的GTK3将FigureCanvasGTK3Agg小部件添加到Gtk.ScrolledWindow。

  1. import gi
  2. gi.require_version('Gtk', '3.0')
  3. from gi.repository import Gtk
  5. from matplotlib.backends.backend_gtk3agg import (
  6.     FigureCanvasGTK3Agg as FigureCanvas)
  7. from matplotlib.figure import Figure
  8. import numpy as np
  10. win = Gtk.Window()
  11. win.connect("delete-event", Gtk.main_quit)
  12. win.set_default_size(400, 300)
  13. win.set_title("Embedding in GTK")
  15. f = Figure(figsize=(5, 4), dpi=100)
  16. a = f.add_subplot(111)
  17. t = np.arange(0.0, 3.0, 0.01)
  18. s = np.sin(2*np.pi*t)
  19. a.plot(t, s)
  21. sw = Gtk.ScrolledWindow()
  22. win.add(sw)
  23. # A scrolled window border goes outside the scrollbars and viewport
  24. sw.set_border_width(10)
  26. canvas = FigureCanvas(f)  # a Gtk.DrawingArea
  27. canvas.set_size_request(800, 600)
  28. sw.add_with_viewport(canvas)
  30. win.show_all()
  31. Gtk.main()
