Member Function Documentation

◆ applyDirectly()

bool QgsDefaultSearchWidgetWrapper::applyDirectly ( )

overridevirtual

If this is true, then this search widget should take effect directly when its expression changes.

Implements QgsSearchWidgetWrapper.

Reimplemented in QgsTextEditSearchWidgetWrapper.

Definition at line 82 of file qgsdefaultsearchwidgetwrapper.cpp.

◆ caseSensitiveCheckBox()

QCheckBox * QgsDefaultSearchWidgetWrapper::caseSensitiveCheckBox ( )

protected

Returns a pointer to the case sensitivity checkbox in the widget.

Note: this method is in place for unit testing only, and is not considered stable API

Definition at line 294 of file qgsdefaultsearchwidgetwrapper.cpp.

◆ clearWidget

void QgsDefaultSearchWidgetWrapper::clearWidget ( )

overrideslot

Definition at line 237 of file qgsdefaultsearchwidgetwrapper.cpp.

◆ createExpression()

QString QgsDefaultSearchWidgetWrapper::createExpression ( QgsSearchWidgetWrapper::FilterFlags flags ) const

overridevirtual

Creates a filter expression based on the current state of the search widget and the specified filter flags.

Parameters

flags filter flags

Returns: filter expression

Reimplemented from QgsSearchWidgetWrapper.

Definition at line 142 of file qgsdefaultsearchwidgetwrapper.cpp.

◆ createWidget()

QWidget * QgsDefaultSearchWidgetWrapper::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 77 of file qgsdefaultsearchwidgetwrapper.cpp.

◆ defaultFlags()

QgsSearchWidgetWrapper::FilterFlags QgsDefaultSearchWidgetWrapper::defaultFlags ( ) const

overridevirtual

Returns the filter flags which should be set by default for the search widget.

See also: supportedFlags()

Reimplemented from QgsSearchWidgetWrapper.

Definition at line 115 of file qgsdefaultsearchwidgetwrapper.cpp.

◆ expression()

QString QgsDefaultSearchWidgetWrapper::expression ( ) 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 QgsSearchWidgetWrapper.

Definition at line 34 of file qgsdefaultsearchwidgetwrapper.cpp.

◆ initWidget()

void QgsDefaultSearchWidgetWrapper::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 249 of file qgsdefaultsearchwidgetwrapper.cpp.

◆ lineEdit()

QgsFilterLineEdit * QgsDefaultSearchWidgetWrapper::lineEdit ( )

protected

Returns a pointer to the line edit part of the widget.

Note: this method is in place for unit testing only, and is not considered stable API

Definition at line 289 of file qgsdefaultsearchwidgetwrapper.cpp.

◆ setEnabled

void QgsDefaultSearchWidgetWrapper::setEnabled ( bool enabled )

overrideslot

Definition at line 242 of file qgsdefaultsearchwidgetwrapper.cpp.

◆ setExpression

void QgsDefaultSearchWidgetWrapper::setExpression ( const QString & exp )

overrideprotectedslot

Definition at line 56 of file qgsdefaultsearchwidgetwrapper.cpp.

◆ supportedFlags()

QgsSearchWidgetWrapper::FilterFlags QgsDefaultSearchWidgetWrapper::supportedFlags ( ) const

overridevirtual

Returns filter flags supported by the search widget.

See also: defaultFlags()

Reimplemented from QgsSearchWidgetWrapper.

Definition at line 87 of file qgsdefaultsearchwidgetwrapper.cpp.

◆ valid()

bool QgsDefaultSearchWidgetWrapper::valid ( ) const

overrideprotectedvirtual

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.
