class DISPLIB::ButterflyView

QRhi-accelerated butterfly viewer overlaying every channel of one or more averaged conditions.

Renders all visible traces in a single shader pass for smooth zoom / pan; visibility per modality and per condition is driven by ModalitySelectionView and AverageSelectionView. Used as the main evoked viewer in MNE-Scan.

Inheritance​

Public Methods​

ButterflyView(sSettingsPath, parent, f)​

The constructor.

Parameters:

  • sSettingsPath : const QString & QSettings key prefix used to persist view settings (default empty).

  • parent : *QWidget ** Parent widget (default 0).

  • f : Qt::WindowFlags Window flags passed to the widget (default Qt::Widget).

~ButterflyView()​

Destroys the ButterflyView.

updateViewport()​

Update the viewport.

This, e.g., necessary if this widget was set to a QDockWidget which changes its floating state.

setEvokedSetModel(model)​

Set the evoked set model.

Parameters:

getEvokedSetModel()​

Returns the currently set EvokedSetModel.

Returns:

dataUpdate()​

Perform a data update.

getModalityMap()​

Get the activation of the already created modality check boxes.

Returns:

  • QMap< QString, bool > — The current modality map.

setModalityMap(modalityMap)​

Set the modality checkboxes.

Parameters:

  • modalityMap : const QMap< QString, bool > & The modality map.

setScaleMap(scaleMap)​

Sets the scale map to scaleMap.

Parameters:

  • scaleMap : const QMap< qint32, float > & map with all channel types and their current scaling value.

setSelectedChannels(selectedChannels)​

Set the selected channels.

Parameters:

  • selectedChannels : const QList< int > & The new selected channels.

updateView()​

Perform a view update from outside of this class.

setBackgroundColor(backgroundColor)​

Set the background color.

Parameters:

  • backgroundColor : const QColor & The new background color.

getBackgroundColor()​

Returns the background color.

Returns:

  • const QColor & — The current background color.

takeScreenshot(fileName)​

Renders a screenshot of the view and saves it to the passed path.

SVG and PNG supported.

Parameters:

  • fileName : const QString & The file name and path where to store the screenshot.

getAverageColor()​

Get the current average colors.

Returns:

  • QSharedPointer< QMap< QString, QColor > > — Pointer to the current average colors.

getAverageActivation()​

Get the current average activations.

Returns:

  • QSharedPointer< QMap< QString, bool > > — Pointer to the current average activations.

setAverageColor(qMapAverageColor)​

Set the average colors.

Parameters:

  • qMapAverageColor : const QSharedPointer< QMap< QString, QColor > > Pointer to the new average colors.

setSingleAverageColor(avgColor)​

Sets the color used to draw the average to avgColor.

Parameters:

  • avgColor : const QColor & Color of averaged signal.

setAverageActivation(qMapAverageActivation)​

Set the average activations.

Parameters:

  • qMapAverageActivation : const QSharedPointer< QMap< QString, bool > > Pointer to the new average activations.

setChannelInfoModel(pChannelInfoModel)​

Set the channel info model.

Parameters:

  • pChannelInfoModel : QSharedPointer<ChannelInfoModel> & The new channel info model.

showSelectedChannelsOnly(selectedChannels)​

Only shows the channels defined in the QStringList selectedChannels.

Parameters:

  • selectedChannels : const QStringList & list of all channel names which are currently selected in the selection manager.

showSelectedChannels(selectedChannelsIndexes)​

Shows selected channels based on a list of selected channel indices.

Parameters:

  • selectedChannelsIndexes : const QList< int > list of indices of channels channels to be displayed.

showAllChannels()​

Shows all channels in view.

saveSettings()​

Saves all important settings of this view via QSettings.

loadSettings()​

Loads and inits all important settings of this view via QSettings.

clearView()​

Clears the view.
