The QgsSpinBox is a spin box with a clear button that will set the value to the defined clear value.
Represents a mesh layer supporting display of data on structured or unstructured meshes.
Definition: qgsmeshlayer.h:99
A widget for setup of the vector dataset renderer settings of a mesh layer.
QgsMeshRendererVectorSettingsWidget(QWidget *parent=nullptr)
A widget to hold the renderer Vector settings for a mesh layer.
void setActiveDatasetGroup(int groupIndex)
Associates a dataset group with the widget (should be set before syncToLayer())
QgsMeshRendererVectorSettings settings() const
Returns vector settings.
void syncToLayer()
Synchronizes widgets state with associated mesh layer.
void setLayer(QgsMeshLayer *layer)
Associates mesh layer with the widget.
void widgetChanged()
Mesh rendering settings changed.
Represents a renderer settings for vector datasets.
