This class is a menu that is populated automatically with the actions defined for a given layer.
This class contains context information for attribute editor widgets.
FilterType
Filter types.
QgsAttributeTableAction(const QString &name, QgsDualView *dualView, QUuid action, const QModelIndex &fieldIdx)
Create a new attribute table action.
This is a container for configuration of the attribute table.
FilterMode
The filter mode defines how the rows should be filtered.
QgsAttributeTableMapLayerAction(const QString &name, QgsDualView *dualView, QgsMapLayerAction *action, const QModelIndex &fieldIdx)
A model backed by a QgsVectorLayerCache which is able to provide feature/attribute information to a Q...
Provides a table view of features of a QgsVectorLayer.
This widget is used to show the attributes of a set of features of a QgsVectorLayer.
Definition qgsdualview.h:45
void showContextMenuExternally(QgsActionMenu *menu, QgsFeatureId fid)
Emitted when selecting context menu on the feature list to create the context menu individually.
ViewMode
The view modes, in which this widget can present information.
Definition qgsdualview.h:56
QgsAttributeTableFilterModel::FilterMode filterMode()
Gets the filter mode.
QgsFeatureIds filteredFeatures()
Gets a list of currently visible feature ids.
void filterChanged()
Emitted whenever the filter changes.
QgsAttributeTableView * tableView()
Returns the table view.
void formModeChanged(QgsAttributeEditorContext::Mode mode)
Emitted when the form changes mode.
FeatureListBrowsingAction
Action on the map canvas when browsing the list of features.
Definition qgsdualview.h:75
@ PanToFeature
The map is panned to the center of the feature bounding-box.
Definition qgsdualview.h:77
@ ZoomToFeature
The map is zoomed to contained the feature bounding-box.
Definition qgsdualview.h:78
void filterExpressionSet(const QString &expression, QgsAttributeForm::FilterType type)
Emitted when a filter expression is set using the view.
void displayExpressionChanged(const QString &expression)
Emitted whenever the display expression is successfully changed.
QgsAttributeTableModel * masterModel() const
Returns the model which has the information about all features (not only filtered)
Expression contexts are used to encapsulate the parameters around which a QgsExpression should be eva...
Class for parsing and evaluation of expressions (formerly called "search strings").
This class wraps a request for features to a vector layer (or directly its vector data provider).
The feature class encapsulates a single feature including its unique ID, geometry and a list of field...
Definition qgsfeature.h:58
A widget for customizing conditional formatting options.
Is an interface class to abstract feature selection handling.
Map canvas is a class for displaying all GIS data types on a canvas.
An action which can run on map layers The class can be used in two manners:
A QScrollArea subclass with improved scrolling behavior.
This class caches features of a given QgsVectorLayer.
Represents a vector layer which manages a vector based data sets.
