Member Function Documentation

◆ context()

QgsSymbolWidgetContext QgsDataDefinedValueDialog::context ( ) const

Returns the context in which the symbol widget is shown, e.g., the associated map canvas and expression contexts.

See also: setContext()

Since: QGIS 3.0

Definition at line 399 of file qgsrendererwidget.cpp.

◆ dataDefinedChanged

void QgsDataDefinedValueDialog::dataDefinedChanged ( )

slot

Definition at line 475 of file qgsrendererwidget.cpp.

◆ init()

void QgsDataDefinedValueDialog::init ( int propertyKey )

protected

Should be called in the constructor of child classes.

Note: May be missing Python bindings depending on the platform.

Definition at line 438 of file qgsrendererwidget.cpp.

◆ setContext()

void QgsDataDefinedValueDialog::setContext ( const QgsSymbolWidgetContext & context )

Sets the context in which the symbol widget is shown, e.g., the associated map canvas and expression contexts.

Parameters

context symbol widget context

See also: context()

Since: QGIS 3.0

Definition at line 394 of file qgsrendererwidget.cpp.

◆ vectorLayer()

const QgsVectorLayer* QgsDataDefinedValueDialog::vectorLayer ( ) const

inline

Returns the vector layer associated with the widget.

Since: QGIS 2.12
