Label text does not span width of container

[Nicodaemus <johnanderson78 dodo com au>]

Hello,

I have a simple program with a label on the main window.

I place some text in the label and set the 'set_line_wrap' property of 
the label to True.

However, when I run the script I notice that the text in the label does 
not span the entire width of the window, as there are left and right 
borders of space surrounding the label's text.

How do I alter the properties of the label so that the rendered text in 
the label spans the entire width of the parent window/container?

I have tried using a v/hbox without success, and experimenting with 
glade and various container configurations yields the same outcome.

I do not want to alter the width of the window to match the width of the 
rendered text, but would prefer to have the width of the rendered text 
meet the left and right edges of the window (thereby also reducing the 
number of lines of text).

Removing the 'set_line_wrap(True)' directive for the label creates a 
label with a single line and stretches the parent window beyond the 
limits of the screen to accomodate the text in the label - something 
that is not desirable.

I would like the text of the label to meet the left and right edges of 
the parent window/container if possible.

Any assistance will be appreciated.
