Member Function Documentation

◆ createWidget()

QWidget * QgsTextWidgetWrapper::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 35 of file qgstextwidgetwrapper.cpp.

◆ initWidget()

void QgsTextWidgetWrapper::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 58 of file qgstextwidgetwrapper.cpp.

◆ needsGeometry()

bool QgsTextWidgetWrapper::needsGeometry ( ) const

Returns true if the widget needs feature geometry.

Definition at line 108 of file qgstextwidgetwrapper.cpp.

◆ reinitWidget()

void QgsTextWidgetWrapper::reinitWidget ( )

Clears the content and makes new initialization.

Definition at line 81 of file qgstextwidgetwrapper.cpp.

◆ setFeature

void QgsTextWidgetWrapper::setFeature ( const QgsFeature & feature )

overrideslot

Definition at line 129 of file qgstextwidgetwrapper.cpp.

◆ setText()

void QgsTextWidgetWrapper::setText ( const QString & text )

Sets the text code to htmlCode.

Definition at line 90 of file qgstextwidgetwrapper.cpp.

◆ valid()

bool QgsTextWidgetWrapper::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.

Implements QgsWidgetWrapper.

Definition at line 30 of file qgstextwidgetwrapper.cpp.
