Class Details¶

class v_sim.GlExtScale(**kwargs)¶

Bases:: v_sim.GlExt, v_sim.GlExtLined
Abstract:: No
Structure:: v_sim.GlExtScaleClass

All fields are private, use the access routines.

New in version 3.3.

classmethod new(name)¶

Parameters:: name (str or None) – a name for the v_sim.GlExt.
Returns:: a newly created v_sim.GlExtScale object.
Return type:: v_sim.GlExtScale

Create a new arrow set without any elements. Add arrows with v_sim.GlExtScale.add().

New in version 3.3.

add(origin, orientation, length, legend)¶

Parameters:

origin ([float]) – the origin ;
orientation ([float]) – the orientation in cartesian coordinates ;
length (float) – the length of the arrow ;
legend (str or None) – the text going with the arrow (can be None).

Returns:

the id of the newly added arrow.

Return type:

int

Create a new arrow pointing somewhere in the box with a label. If legend is None, then the label will be the value of the length.

New in version 3.7.

getLegend(i)¶

Parameters:: i (int) – the ith arrow.
Returns:: a string (private, do not free it).
Return type:: str or None

A v_sim.GlExtScale can have a legend. This is not actualy the string printed on screen but the one used to generate it.

New in version 3.3.

getLength(i)¶

Parameters:: i (int) – the ith arrow.
Returns:: a positive floating point value or a negative value if i is not in the arrow list.
Return type:: float

A v_sim.GlExtScale is characterised by its length.

New in version 3.3.

getNArrows()¶

Returns:: the number of stored arrows.
Return type:: int

A v_sim.GlExtScale is characterised by a set of arrows.

New in version 3.7.

getOrientation(i)¶

Parameters:: i (int) – the ith arrow.
Returns:: three floating point values.
Return type:: [float] or None

A v_sim.GlExtScale is characterised by its orientation in cartesian coordinates.

New in version 3.3.

getOrigin(i)¶

Parameters:: i (int) – the ith arrow.
Returns:: three floating point values.
Return type:: [float] or None

A v_sim.GlExtScale is characterised by its origin in cartesian coordinates.

New in version 3.3.

setLegend(i, value)¶

Parameters:

i (int) – the ith arrow ;
value (str or None) – a string (can be None).

Returns:

True if the legend was actually changed.

Return type:

bool

Routine that changes the legend of the scale. If value is None then the length of the scale is printed.

New in version 3.3.

setLength(i, lg)¶

Parameters:

i (int) – the ith arrow ;
lg (float) – a positive length.

Returns:

True if the length was actually changed.

Return type:

bool

Routine that changes the length of the scale. If i is zero and self has currently no arrow, a default one is created.

New in version 3.3.

setOrientation(i, xyz, mask)¶

Parameters:

i (int) – the ith arrow ;
xyz ([float]) – a vector in cartesian coordinates ;
mask (int) – relevant values in xyz, see v_sim.XYZ_MASK_X…

Returns:

True if the orientation was actually changed.

Return type:

bool

Routine that changes the direction of the scale.

New in version 3.3.

setOrigin(i, xyz, mask)¶

Parameters:

i (int) – the ith arrow ;
xyz ([float]) – a vector in cartesian coordinates ;
mask (int) – relevant values in xyz, see v_sim.XYZ_MASK_X…

Returns:

True if the origin was actually changed.

Return type:

bool

Routine that changes the origin of the scale.

New in version 3.3.
