Definition: Knob.hpp:41
static Knob::Ptr create()
Creates a new knob widget.
bool isMouseOnWidget(Vector2f pos) const override
Returns whether the mouse position (which is relative to the parent widget) lies on top of the widget...
float getMinimum() const
Returns the value when the knob would be rotated in the direction of StartRotation.
std::shared_ptr< const Knob > ConstPtr
Shared constant widget pointer.
Definition: Knob.hpp:45
std::shared_ptr< Knob > Ptr
Shared widget pointer.
Definition: Knob.hpp:44
void setValue(float value)
Changes the current value.
void load(const std::unique_ptr< DataIO::Node > &node, const LoadingRenderersMap &renderers) override
Loads the widget from a tree of nodes.
void rendererChanged(const String &property) override
Function called when one of the properties of the renderer is changed.
float getEndRotation() const
Sets the end rotation, which is the place where the value should be maximal.
KnobRenderer * getSharedRenderer()
Returns the renderer, which gives access to functions that determine how the widget is displayed.
float getStartRotation() const
Returns the start rotation, which is the place where the value should be minimal.
void setEndRotation(float endRotation)
Sets the end rotation, which is the place where the value should be maximal.
void draw(BackendRenderTarget &target, RenderStates states) const override
Draw the widget to a render target.
float getMaximum() const
Returns the value when the knob would be rotated in the direction of EndRotation.
KnobRenderer * getRenderer()
Returns the renderer, which gives access to functions that determine how the widget is displayed.
float getValue() const
Returns the current value.
static Knob::Ptr copy(Knob::ConstPtr knob)
Makes a copy of another knob.
void setClockwiseTurning(bool clockwise)
Should the value increase when turning the knob clockwise?
bool getClockwiseTurning() const
Returns whether the value increases when turning the knob clockwise?
Widget::Ptr clone() const override
Makes a copy of the widget if you don't know its exact type.
void setSize(const Layout2d &size) override
Changes the size of the knob.
std::unique_ptr< DataIO::Node > save(SavingRenderersMap &renderers) const override
Saves the widget as a tree node in order to save it to a file.
void setStartRotation(float startRotation)
Sets the start rotation, which is the place where the value should be minimal.
void setMinimum(float minimum)
Sets the value for when the knob would be rotated in the direction of StartRotation.
void setMaximum(float maximum)
Sets the value for when the knob would be rotated in the direction of EndRotation.
Signal & getSignal(String signalName) override
Retrieves a signal based on its name.
