The builder widget that is used by the dialog
%End

Returns the expected format string, which is shown in the dialog. This
is purely a text format and no expression validation is done against it.

Set the ``expected`` format string, which is shown in the dialog. This
is purely a text format and no expression validation is done against it.

Returns the expression context for the dialog. The context is used for
the expression preview result and for populating the list of available
functions and variables.

%Docstring
Sets the expression context for the dialog. The context is used for the
expression preview result and for populating the list of available
functions and variables.

%Docstring
Sets geometry calculator used in distance/area calculations.
%End

Allow accepting invalid expressions. This can be useful when we are not
able to provide an expression context of which we are sure it's
completely populated.

Allow accepting expressions with evaluation errors. This can be useful
when we are not able to provide an expression context of which we are
sure it's completely populated.

Allow accepting expressions with evaluation errors. This can be useful
