Label indicating the dimensions of heatmap.
self.temperature
Label indicating temperature scaling in heatmap, with the
widgets self.red_image, seld.red, self.green_image,
self.green, self.blue_image and self.blue.
Other attributes:
self.data
Data instance which contains the temperature field.
Initialized when simulation starts, deleted when it ends.

_showerror(self, error):
Used to show any error that the user may encounter.
addobject(self):
Command of the "Add Object" option in "Object" menu.
Creates an Object object to support object creation.
If created, object is shown on the heatmap.

Export the work sheet to an Excel file for further
data manipulation.
fieldtemp(self, *args):
Callback method of the field temperature entry.
Verifies if the entry can be treated as a number.
fill(self, color):
Fill image with a color = (r, b, g). Used at
initialization of interface and at end of simulation.
help(self):
Command of "Help" in the main menu. Opens a html
page with some guidelines on how to use this program.
newpoint(self):
Adds a new point to ths list of points for which the
temperature values will be kept in an Excel work sheet.
outsidetemp(self. *args):
Callback method of the outside temperature entry.
Verifies if the entry can be treated as a number.
pause(self):
Command to pause simulation.
quit(self):
Method called when the user interface is closed.

Command to resume simulation.
run(self):
Iterate numerical data and update heatmap.
showobject(self, object):
Show the object on the heatmap.
showwindow(self, window):
Show the window on the heatmap.
start(self):
Default command of self.startbutton. Starts simulation.
If no object or window is added, raises UniformFieldError.
Otherwise, creates the data array and the initial heatmap.
todelete_object(self):
Allows user to choose the object he wants to delete.
todelete_window(self):
Allows user to choose the window he wants to delete.
tomodify_object(self):
Allows user to choose the object he wants to modify.
tomodify_window(self):
Allows user to choose the window he wants to modify.
Exceptions handled:
AttributeError
When user attempts to start simulation without any value
for the field temperature or the outside temperature.
ValueError
When the field temperature entry is either physically
impossible or unsuitable for the simulation.
UniformFieldError
When user tries to start simulation with no object or window.
