Member Function Documentation

◆ config()

QVariantMap QgsValueMapConfigDlg::config ( )
overridevirtual

Create a configuration from the current GUI state.

Returns
A widget configuration

Implements QgsEditorConfigWidget.

Definition at line 47 of file qgsvaluemapconfigdlg.cpp.

◆ eventFilter()

bool QgsValueMapConfigDlg::eventFilter ( QObject *  watched,
QEvent *  event 
)
override

Definition at line 215 of file qgsvaluemapconfigdlg.cpp.

◆ populateComboBox()

void QgsValueMapConfigDlg::populateComboBox ( QComboBox *  comboBox,
const QVariantMap &  configuration,
bool  skipNull 
)
static

Populates a comboBox with the appropriate entries based on a value map configuration.

If skipNull is true, then NULL entries will not be added.

Since
QGIS 3.0

Definition at line 186 of file qgsvaluemapconfigdlg.cpp.

◆ setConfig()

void QgsValueMapConfigDlg::setConfig ( const QVariantMap &  config)
overridevirtual

Update the configuration widget to represent the given configuration.

Parameters
configThe configuration which should be represented by this widget

Implements QgsEditorConfigWidget.

Definition at line 82 of file qgsvaluemapconfigdlg.cpp.

void QgsValueMapConfigDlg::updateMap ( const QMap< QString, QVariant > &  map,
bool  insertNull 
)

Updates the displayed table with the values from map.

If insertNull is set to true, it will also insert a NULL value.

Note
In most cases the overload that accepts a list is preferred as it keeps the order of the values.

Definition at line 149 of file qgsvaluemapconfigdlg.cpp.

◆ updateMap() [2/2]

void QgsValueMapConfigDlg::updateMap ( const QList< QPair< QString, QVariant >> &  list,
bool  insertNull 
)

Updates the displayed table with the values from list, the order of the values is preserved.

If insertNull is set to true, it will also insert a NULL value.
