		QWidget *	editor,

Member Function Documentation

◆ createWidget()

QWidget * QgsQmlWidgetWrapper::createWidget ( QWidget * parent )

overridevirtual

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

parent You should set this parent on the created widget.

Returns: A new widget

Implements QgsWidgetWrapper.

Definition at line 36 of file qgsqmlwidgetwrapper.cpp.

◆ initWidget()

void QgsQmlWidgetWrapper::initWidget ( QWidget * editor )

overridevirtual

This method should initialize the editor widget with runtime data.

Fill your comboboxes here.

Parameters

editor The widget which will represent this attribute editor in a form.

Reimplemented from QgsWidgetWrapper.

Definition at line 41 of file qgsqmlwidgetwrapper.cpp.

◆ reinitWidget()

void QgsQmlWidgetWrapper::reinitWidget ( )

Clears the content and makes new initialization.

Definition at line 61 of file qgsqmlwidgetwrapper.cpp.

◆ setFeature

void QgsQmlWidgetWrapper::setFeature ( const QgsFeature & feature )

overrideslot

Definition at line 101 of file qgsqmlwidgetwrapper.cpp.

◆ setQmlCode()

void QgsQmlWidgetWrapper::setQmlCode ( const QString & qmlCode )

writes the qmlCode into a temporary file

Definition at line 71 of file qgsqmlwidgetwrapper.cpp.

◆ valid()

bool QgsQmlWidgetWrapper::valid ( ) const

overridevirtual

Returns true if the widget has been properly initialized.

This acts as hint for the calling party if this wrapper can be used after initializing it. If it cannot be used this is a hint to the caller that he may try to find another suitable widget type instead.

Returns: Validity status of this widget.

Since: QGIS 2.12
