This class is a composition of two QSettings instances:
Definition: qgssettings.h:58
This class contains context information for attribute editor widgets.
bool save()
Save all the values from the editors to the layer.
void setHighlight(QgsHighlight *h)
setHighlight
void setVectorLayerTools(QgsVectorLayerTools *vlTools)
Sets the associated vector layer tools.
The feature class encapsulates a single feature including its id, geometry and a list of field/values...
Definition: qgsfeature.h:55
void setVectorLayerTools(const QgsVectorLayerTools *tools)
Set the vector layer tools that will be used to interact with the data.
void setMode(QgsAttributeEditorContext::Mode mode)
Change the mode of the actions.
void saveGeometry(QWidget *widget, const QString &keyName)
Save the wigget geometry into settings.
bool restoreGeometry(QWidget *widget, const QString &keyName)
Restore the wigget geometry from settings.
void show()
Show the dialog non-blocking. Reparents this dialog to be a child of the dialog form.
QgsAttributeDialog(QgsVectorLayer *vl, QgsFeature *thepFeature, bool featureOwner, QWidget *parent=nullptr, bool showDialogButtons=true, const QgsAttributeEditorContext &context=QgsAttributeEditorContext())
Create an attribute dialog for a given layer and feature.
This class is a menu that is populated automatically with the actions defined for a given layer...
Definition: qgsactionmenu.h:38
A class for highlight features on the map.
Definition: qgshighlight.h:56
void setMode(QgsAttributeEditorContext::Mode mode)
Toggles the form mode.
void disconnectButtonBox()
Disconnects the button box (OK/Cancel) from the accept/resetValues slots If this method is called...
void rollback()
Delete all features which have been added via this object.
void setMode(QgsAttributeEditorContext::Mode mode)
Sets the current mode of the form.
bool event(QEvent *e) override
Intercept window activate/deactivate events to show/hide the highlighted feature. ...
void reject() override
void setFormMode(FormMode mode)
Sets the form mode.
void setValue(const QString &key, const QVariant &value, QgsSettings::Section section=QgsSettings::NoSection)
Sets the value of setting key to value.
QgsAttributeEditorContext::Mode mode() const
