Member Function Documentation

§ createWidget()

QWidget * QgsWebViewWidgetWrapper::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(QWidget*).

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

Implements QgsWidgetWrapper.

Definition at line 71 of file qgswebviewwidgetwrapper.cpp.

§ initWidget()

void QgsWebViewWidgetWrapper::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 92 of file qgswebviewwidgetwrapper.cpp.

§ setEnabled

void QgsWebViewWidgetWrapper::setEnabled ( bool  enabled)
overrideslot

Definition at line 162 of file qgswebviewwidgetwrapper.cpp.

§ setValue

void QgsWebViewWidgetWrapper::setValue ( const QVariant &  value)
overrideslot

Definition at line 149 of file qgswebviewwidgetwrapper.cpp.

§ showIndeterminateState()

void QgsWebViewWidgetWrapper::showIndeterminateState ( )
overridevirtual

Sets the widget to display in an indeterminate "mixed value" state.

Note
added in QGIS 2.16

Reimplemented from QgsEditorWidgetWrapper.

Definition at line 60 of file qgswebviewwidgetwrapper.cpp.

§ valid()

bool QgsWebViewWidgetWrapper::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 tothe caller that he may try to find another suitable widget type instead.

Returns
Validity status of this widget.
Note
Added in 2.12

Implements QgsWidgetWrapper.

Definition at line 144 of file qgswebviewwidgetwrapper.cpp.

§ value()

QVariant QgsWebViewWidgetWrapper::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
