    text
    copied!<p>Heh, the title must sound dreadful and noobish</p> <p>Anyway, I'm working on a simple web game that's basically a labyrinth. To make a map I have to manually write coordinates of walls, and I thought it'd speed up the development process greatly if I'd make a map editor. The first thing that came to my mind was python's tkinter generating a grid of combo boxes.</p> <p>The grid is generated fine, but I have problems with exporting the "map". I think each combobox has to have an unique text variable and a way to check it's coordinates. I thought I'd solve both problems if I'd set the variable's name to its coordinates, but I don't think it's working and I don't know how to access the values later on. Here's the important bit of the code (sorry for not showing everything right away, but StackOverflow's formatting is horrible when posting python):</p> <pre><code>def scale(self, *args, **kwargs): self.width.set(self.setwidth.get()) self.height.set(self.setheight.get()) name=[0,0] while name[0]&lt;=(self.width.get() - 1) and name[1]&lt;=self.height.get(): n=(str(name[0]) + ',' + str(name[1])) o={'name': n} self.o['name']=tk.StringVar() self.n=ttk.Combobox(self, textvariable=o['name'], values=('F', 'W', 'V', 'S'), width=1, state='readonly') self.n.grid(column=name[0], row=(name[1] + 1)) self.n.set('V') print self.o['name'].get() if name[0]==(self.width.get() - 1) and name[1]&lt;self.height.get(): name[0]=0 name[1]=name[1]+1 else: name[0]=name[0]+1 self.update() </code></pre> <p>The code above gives me the <code>App instance has no attribute 'o'</code>... what can I do about it? Can it even be done?</p> <p>Thanks!</p>
