# soya-with-tk-1: Using Soya inside Tk mainloop
# In this lesson, we'll embed Soya's MainLoop inside a Tk mainloop.
# Interfacing Soya with other GUI system should be very similar.
# Notice that, if you have the choice, using the MainLoop in the "normal way"
# may give a smoother animation.
# Import the Soya and Tkinter module.
import sys, os, os.path, soya, soya.widget, Tkinter
soya.init()
soya.path.append(os.path.join(os.path.dirname(sys.argv[0]), "data"))
# Creates a scene.
scene = soya.World()
# Create a body displaying a caterpillar head.
head = soya.Body(scene, soya.Model.get("caterpillar_head"))
# Creates a light.
light = soya.Light(scene)
light.set_xyz(2.0, 5.0, 0.0)
# Creates a camera.
camera = soya.Camera(scene)
camera.set_xyz(0.0, 15.0, 15.0)
camera.look_at(head)
# Creates a widget group, containing the camera and a label showing the FPS.
soya.set_root_widget(soya.widget.Group())
soya.root_widget.add(camera)
soya.root_widget.add(soya.widget.FPSLabel())
# Create the MainLoop, but DON'T start it (= don't call MainLoop.main_loop()).
soya.MainLoop(scene)
# Create a Tk window, with a button.
# When the button is clicked, the head moves up.
class Window(Tkinter.Tk):
def __init__(self):
Tkinter.Tk.__init__(self)
self.button = Tkinter.Button(self, text = "Move upward", command = self.button_click)
self.button.pack()
# Call self.update_soya() in 30 milliseconds (see after's doc for more info).
self.after(30, self.update_soya)
def button_click(self):
head.y += 1
def update_soya(self):
# Call again self.update_soya(), in 30 milliseconds.
# This should be done BEFORE calling soya.MAIN_LOOP.update(), since update may consume time!
self.after(30, self.update_soya)
# Update Soya, and render.
soya.MAIN_LOOP.update()
window = Window()
Tkinter.mainloop()
