Detailed Description

A DataDisplayHandler for UltrasoundSweep.

An ultrasound sweep can be visualized in 2D or 3D views.

For the visualization in the volumetric 3D view a GlSweep3D object is maintained. There is a custom widget in the volumetric view that combines a combo box for the SweepDisplayOptions::RenderMode3d selection with the widget for the DisplayOptions3d nested. The latter is enabled only for the option of SweepDisplayOptions::RenderMode3d::TransferFunction as it is otherwise not applicable.

The widgets for the MPR and plain 2D view are the default DisplayOptions2dWidget widgets.

Upon deletion of the displayed sweeps, this handler takes care of cleaning the views

Member Function Documentation

handlesType()

bool handlesType ( const Data * data ) const

overridevirtual

Check whether this specialization handles the given Data type.

Checks should be as narrow as possible to avoid potential overlap with other handlers.

Implements DataDisplayHandler.

canBeShownInView()

bool canBeShownInView ( const Data * data, const GUI::View & view ) const

overridevirtual

Check whether a particular Data can be shown in the given view.

Used by DataDisplayHandler during view dispatch when calling show(). Should only be called if handlesType(data) == true.

Implements DataDisplayHandler.

show()

void show ( Data * data, GUI::View & view )

overridevirtual

Visualize the given data in the given view.

Should only be called if (handlesType(data) == true) && (canBeShownInView(data, view) == true).

Implements DataDisplayHandler.

hide()

void hide ( Data * data, GUI::View & view )

overridevirtual

Remove the given data from the given view.

Warning

Implementations must not access data beyond pointer comparison because the instance may already in the process of deletion when calling this function.

Implements DataDisplayHandler.

onViewDeleted()

void onViewDeleted ( GUI::View & view )

overridevirtual

Called if a view associated with this DataDisplayHandler is destroyed.

Reimplemented from DataDisplayHandler.

createDisplayOptionsWidget()

std::unique_ptr< QWidget > createDisplayOptionsWidget ( Data * data, GUI::DisplayBase & display, GUI::View & view ) const

overridevirtual

Provides an optional QtWidgets-based GUI to configure display options for the given data shown in view.

This function is used to enable InteractiveViewOptionsOverlay showing a suitable GUI for all data shown in its corresponding view. The default implementation returns nullptr.

Note

This function is still considered experimental and may be moved/changed in the future.

Reimplemented from DataDisplayHandler.
