Member Function Documentation

◆ createWidget()

QWidget * QgsRangeWidgetWrapper::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

parent You should set this parent on the created widget.

Returns: A new widget

Implements QgsWidgetWrapper.

Definition at line 31 of file qgsrangewidgetwrapper.cpp.

◆ initWidget()

void QgsRangeWidgetWrapper::initWidget ( QWidget * editor )

overrideprotectedvirtual

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 75 of file qgsrangewidgetwrapper.cpp.

◆ setValue

void QgsRangeWidgetWrapper::setValue ( const QVariant & value )

overrideslot

Definition at line 219 of file qgsrangewidgetwrapper.cpp.

◆ valid()

bool QgsRangeWidgetWrapper::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.

Definition at line 166 of file qgsrangewidgetwrapper.cpp.

◆ value()

QVariant QgsRangeWidgetWrapper::value ( ) const

overridevirtual

Will be used to access the widget's value.

Read the value from the widget and return it properly formatted to be saved in the attribute.

If an invalid variant is returned this will be interpreted as no change. Be sure to return a NULL QVariant if it should be set to NULL.

Returns: The current value the widget represents

Implements QgsEditorWidgetWrapper.
