Class Group

source code

DOCME

Emits signals:

'resized': when the size of the group changes; parameters are its absolute width and height before the change.
'mapped': when the group is about to be visible, that is when it is in the canvas and is absolutely visible

DOCME more signals.

source code

x.__init__(...) initializes x; see x.__class__.__doc__ for signature

Overrides: object.__init__: (inherited documentation)

is_mapped(self)

source code

True when the group is visible, that is when it is in a canvas and absolute_visible is True

Decorators:

@property

get_factors_relative(self, unit)

source code


Compute the size in relative coordinates, that is in the group's
coordinates system, of one 'unit' for the x-axis and for the y-axis.

Example: to know how much one pixel is on the x-axis:
         pixel_in_x, pixel_in_y = get_factors_relative("px")

@param unit: unit for which to compute the factors
@param unit: str

@rtype: 2-tuple of float

get_factors_absolute(self, unit)

source code


Compute the size in absolute coordinates, that is the canvas
coordinates system, of one 'unit' for the x-axis and for the y-axis.

Example: to know how much one pixel is on the x-axis:
         pixel_in_x, pixel_in_y = get_factors_absolute("px")
