Setting up a broad GUI structure
Let's now set up the broad GUI elements of our program. We create a PaintApplication class in 6.01.py. Since we want to draw the menu using our framework, we import the framework into our file and inherit from the Framework class as follows:
import framework class PaintApplication(framework.Framework): def __init__(self, root): super().__init__(root) self.create_gui()
The __init__ method calls another method, create_gui, which is responsible for creating the basic GUI structure for our program.
The create_gui method simply delegates the task to five separate methods, each being responsible for creating one section of the GUI as follows (see code 6.01.py):
def create_gui(self):
self.create_menu()
self.create_top_bar()
self.create_tool_bar()
self.create_drawing_canvas()
self.bind_menu_accelrator_keys()These five methods together build a structure as shown in the following figure (see code 6.01.py...
