QgsRendererWidget (QgsVectorLayer *layer, QgsStyle *style) | |
void | applyChanges () |
This method should be called whenever the renderer is actually set on the layer. | |
QgsSymbolWidgetContext | context () const |
Returns the context in which the renderer widget is shown, e.g., the associated map canvas and expression contexts. | |
QgsExpressionContext | createExpressionContext () const override |
This method needs to be reimplemented in all classes which implement this interface and return an expression context. | |
virtual void | disableSymbolLevels () |
Disables symbol level modification on the widget. | |
virtual void | setContext (const QgsSymbolWidgetContext &context) |
Sets the context in which the renderer widget is shown, e.g., the associated map canvas and expression contexts. | |
void | setDockMode (bool dockMode) override |
Set the widget in dock mode which tells the widget to emit panel widgets and not open dialogs. | |
void | showSymbolLevelsDialog (QgsFeatureRenderer *r) |
Show a dialog with renderer's symbol level settings. | |
const QgsVectorLayer * | vectorLayer () const |

QgsPanelWidget (QWidget *parent=nullptr) | |
Base class for any widget that can be shown as a inline panel. | |
virtual bool | applySizeConstraintsToStack () const |
Returns true if the size constraints and hints for the panel widget should be applied to the parent QgsPanelWidgetStack which this panel is shown in. | |
bool | autoDelete () |
The the auto delete property on the widget. | |
void | connectChildPanel (QgsPanelWidget *panel) |
Connect the given sub panel widgets showPanel signals to this current panels main showPanel event to bubble up to the user. | |
void | connectChildPanels (const QList< QgsPanelWidget * > &panels) |
Connect the given sub panel widgets showPanel signals to this current panels main showPanel event to bubble up to the user. | |
bool | dockMode () |
Returns the dock mode state. | |
virtual QMenu * | menuButtonMenu () |
Returns the menu to use for the menu button for this panel, or nullptr if no menu button is required. | |
virtual QString | menuButtonTooltip () const |
Returns the (translated) tooltip text to use for the menu button for this panel. | |
QString | panelTitle () |
The title of the panel. | |
void | setAutoDelete (bool autoDelete) |
