Member Function Documentation

◆ createWidget()

QWidget * QgsRelationWidgetWrapper::createWidget ( QWidget *  parent)
overrideprotectedvirtual

This method should create a new widget with the provided parent.

This will only be called if the form did not already provide a widget, so it is not guaranteed to be called! You should not do initialization stuff, which also has to be done for custom editor widgets inside this method. Things like filling comboboxes and assigning other data which will also be used to make widgets on forms created in the QtDesigner usable should be assigned in initWidget().

Parameters
parentYou should set this parent on the created widget.
Returns
A new widget

Implements QgsWidgetWrapper.

Definition at line 39 of file qgsrelationwidgetwrapper.cpp.

◆ forceSuppressFormPopup()

◆ initWidget()

void QgsRelationWidgetWrapper::initWidget ( QWidget *  editor)
