takes care of drawing 2D axes
Definition: vtkAxis.h:178
Class for drawing 2D primitives to a graphical context.
Definition: vtkContext2D.h:73
Clipped, transformed area with axes for context items.
virtual void ComputeViewTransform()
data structure to represent mouse events.
all children of this item are transformed by the vtkTransform2D of this item.
a simple class to control print indentation
Definition: vtkIndent.h:113
Implements zooming and panning in a vtkContextArea.
bool MouseWheelEvent(const vtkContextMouseEvent &mouse, int delta) override
Mouse wheel event, positive delta indicates forward movement of the wheel.
bool Hit(const vtkContextMouseEvent &mouse) override
Return true if the supplied x, y coordinate is inside the item.
~vtkInteractiveArea() override
bool MouseButtonPressEvent(const vtkContextMouseEvent &mouse) override
Mouse button down event Return true if the item holds the event, false if the event can be propagated...
bool MouseMoveEvent(const vtkContextMouseEvent &mouse) override
Mouse move event.
