%Docstring(signature="appended")
|
|
The :py:class:`QgsExpressionLineEdit` widget includes a line edit for entering expressions
|
|
together with a button to open the expression creation dialog.
|
|
|
|
This widget is designed for use in contexts where no layer fields are available for
|
|
use in an expression. In contexts where the expression is directly associated with
|
|
a layer and fields can be used, then :py:class:`QgsFieldExpressionWidget` is a more appropriate
|
|
choice as it gives users direct access to select fields from a drop-down list.
|
|
|
|
:py:class:`QgsExpressionLineEdit` also supports a multiline editor mode which is useful where
|
|
more space is available for the widget, but where :py:class:`QgsExpressionBuilderWidget`
|
|
is too complex or large for use.
