    <p>You could add an attribute to the class that you're working like this:</p> <pre><code>self.isDisarmed = False </code></pre> <p>Then add this line to <code>bomb_disarmed</code>:</p> <pre><code>self.isDisarmed = True </code></pre> <p>Then in <code>explode_first</code>, add a test to see if the bomb has been disarmed:</p> <pre><code>def explode_first(self): if self.bomb: if self.isDisarmed: self.parent.after(125, self.explode_fourth) # If bomb is disarmed, skip to the last step, where the bomb is deleted. else: # Otherwise, carry on with bomb explosion self.b1 -= 5 self.b2 -= 5 self.b3 += 5 self.b4 += 5 self.canvas.delete(self.bomb) self.bomb = self.canvas.create_oval(self.b1, self.b2, self.b3, self.b4, fill = "orange") self.parent.after(125, self.explode_second) </code></pre> <p>As a general principle, I would recommend making <code>Bomb</code> a class, which has its own internal attributes and methods. That will make it easier to keep track of what is happening to the bomb, and what the result should be, and it will make it possible to do things like have multiple bombs.</p> <p>EDIT:</p> <p>Re: drawing on an <code>App</code>'s canvas from another class's method, here's one way:</p> <pre><code>class App: def __init__(self, ...): self.canvas = Tkinter.Canvas(...) self.thingy = SomethingElse() class SomethingElse: def __init__(self, parentApp): self.parentApp = parentApp def drawSomething(self): self.parentApp.canvas.create_oval(...) a = App(...) s = SomethingElse(a) s.drawSomething() </code></pre>

    1. COI totally agree with the second bit there, (i'll work on implementing and testing the first bit) but I really struggled to be able to add other objects into the canvas I initialized in my main class. Any pointers there? it seemed that I couldn't access the App class's canvas any way other than with methods I build into the same class.

    2. COHmm, not sure what you mean. As long as you pass the canvas object to another method, that method should be able to draw on the canvas, regardless of what class the method belongs to.

    3. COBut either way, it would be cleaner to have the `App` class's methods handle all the drawing, and just have the `Bomb` class "request" that it be drawn by calling a method from the `App` class.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
