This recipe shows how to add dramatic color effects to our GUI by using the tkinter canvas widget.
We will improve our previous code from GUI_tooltip.py, and we'll improve the look of our GUI by adding some more colors to it.
First, we will create a third tab in our GUI in order to isolate our new code.
Here is the code to create the new third tab:
tabControl = ttk.Notebook(win) # Create Tab Control
tab1 = ttk.Frame(tabControl) # Create a tab
tabControl.add(tab1, text='Tab 1') # Add the tab
tab2 = ttk.Frame(tabControl)
tabControl.add(tab2, text='Tab 2') # Add a second tab
tab3 = ttk.Frame(tabControl)
tabControl.add(tab3, text='Tab 3') # Add a third tab
tabControl.pack(expand=1, fill="both") # Pack to make tabs visibleNext, we use another built-in widget of tkinter: Canvas. A lot of people like this widget because it has powerful capabilities...
