0 | 0 | I'm using some predefined accelerators connected with certain hot keys. Is it possible to temporarily disable them? I don't want to change the hot keys, in order not to confuse users. The accelerators are activated when typing into a combo box, which really is unacceptable. | false | 22,782,726 | 0.099668 | 0 | 0 | 1 | As far as I know you cannot disable them.

I am trying to figure out how to limit the popup box shown bellow. I am not trying to trim the text, I am however trying to set the amount of characters in the popup per line.
eg: 30 Characters per line in the popup box
tkMessageBox.showinfo("Results", str(e))
Any suggestions, without modifying the text... | false | 22,831,462 | 0 | 0 | 0 | 0 | There is nothing you can do with the tkMessageBox. You either have to alter the text or create your own message window. The latter isn't very difficult -- a Toplevel, a Text widget with a scrollbar, and a couple of buttons is about all you need. | 0 | 157 | 0 | 0 | 2014-04-03T08:07:00.000 | python,popup,tkinter,size,line | Tkinter Limit Size Of Popup per line | 0 | 1 | 2 | 22,835,256 | 1 |

As you aim for this to be implemented in Python, I'd start with creating simple PyGame (or other library of your choice) application, that only draws two of your grids. That will help you debug your other functionality, once you'll see it better than array dump in the console.

This could be called for example a creature class. Then based on if the creature is a enemy or player you can control it using an EnemyAI class or a UserInput class.
