QgsScaleWidget creates a combobox which lets the user select map scale

Sets whether to show a button to set the scale to the current scale of

the map canvas next to the combobox.

the map canvas must be defined to show the button

not.

Set the map ``canvas`` associated to the current button.

Returns the selected scale as a double. The scale value indicates the

scale denominator, e.g. 1000.0 for a 1:1000 map.

Returns the minimum scale, or 0 if no minimum scale set. The ``scale``

the minimum scale. Except for 0 which is always allowed.

Helper function to convert a ``scale`` double to scale string. The

``scale`` value indicates the scale denominator, e.g. 1000.0 for a

1:1000 map.

The returned string will be rounded (e.g. 1:1000, not 1:1000.345).

Helper function to convert a scale ``string`` to double. The returned

interpreted as a scale.
