Constructor & Destructor Documentation

◆ QgsRelationWidgetWrapper()

QgsRelationWidgetWrapper::QgsRelationWidgetWrapper ( QgsVectorLayer vl,
const QgsRelation relation,
QWidget *  editor = nullptr,
QWidget *  parent = nullptr 
)
explicit

Constructor for QgsRelationWidgetWrapper.

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 32 of file qgsrelationwidgetwrapper.cpp.

◆ initWidget()

void QgsRelationWidgetWrapper::initWidget ( QWidget *  editor)
overrideprotectedvirtual

This method should initialize the editor widget with runtime data.

Fill your comboboxes here.

Parameters
editorThe widget which will represent this attribute editor in a form.

Reimplemented from QgsWidgetWrapper.

Definition at line 79 of file qgsrelationwidgetwrapper.cpp.

◆ relation()

QgsRelation QgsRelationWidgetWrapper::relation ( ) const

The relation for which this wrapper is created.

Since
QGIS 3.0

Definition at line 49 of file qgsrelationwidgetwrapper.cpp.

◆ setFeature

void QgsRelationWidgetWrapper::setFeature ( const QgsFeature feature)
overrideslot

Definition at line 37 of file qgsrelationwidgetwrapper.cpp.

◆ setShowLabel()

void QgsRelationWidgetWrapper::setShowLabel ( bool  showLabel)

Defines if a title lable should be shown for this widget.

Only has an effect after widget() has been called at least once.

Since
QGIS 2.18

Definition at line 73 of file qgsrelationwidgetwrapper.cpp.

◆ setShowLinkButton()

void QgsRelationWidgetWrapper::setShowLinkButton ( bool  showLinkButton)

Determines if the "link feature" button should be shown.

Since
QGIS 2.18

Definition at line 131 of file qgsrelationwidgetwrapper.cpp.

◆ setShowUnlinkButton()

void QgsRelationWidgetWrapper::setShowUnlinkButton ( bool  showUnlinkButton)

Determines if the "unlink feature" button should be shown.

Since
QGIS 2.18

Definition at line 59 of file qgsrelationwidgetwrapper.cpp.

◆ setVisible

void QgsRelationWidgetWrapper::setVisible ( bool  visible)
slot

Sets the visibility of the wrapper's widget.

Parameters
visibleset to true to show widget, false to hide widget
Since
QGIS 2.16

Definition at line 43 of file qgsrelationwidgetwrapper.cpp.

◆ showLabel()

bool QgsRelationWidgetWrapper::showLabel ( ) const

Defines if a title lable should be shown for this widget.

Only has an effect after widget() has been called at least once.

Since
QGIS 2.18

Definition at line 65 of file qgsrelationwidgetwrapper.cpp.

◆ showLinkButton()

bool QgsRelationWidgetWrapper::showLinkButton ( ) const

Determines if the "link feature" button should be shown.

Since
QGIS 2.18

Definition at line 126 of file qgsrelationwidgetwrapper.cpp.

◆ showUnlinkButton()

bool QgsRelationWidgetWrapper::showUnlinkButton ( ) const

Determines if the "unlink feature" button should be shown.

Since
QGIS 2.18

Definition at line 54 of file qgsrelationwidgetwrapper.cpp.

◆ valid()

bool QgsRelationWidgetWrapper::valid ( ) const
overrideprotectedvirtual

Return 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

Implements QgsWidgetWrapper.
