Public Methods​

RtFiffRawView(sSettingsPath, parent, f)​

Constructs a RtFiffRawView which is a child of parent.

Parameters:

  • sSettingsPath : const QString & Settings path under which the widget persists its state (empty = no persistence).

  • parent : *QWidget ** The parent of widget.

  • f : Qt::WindowFlags Qt window flags passed to the QWidget constructor.

~RtFiffRawView()​

Destroys the RtFiffRawView.

updateViewport()​

Update the viewport.

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

setSettingsPath(sSettingsPath)​

Set the path where to store the settings of this widget via QSettings.

Note that this will also trigger a reload of the stored settings.

Parameters:

  • sSettingsPath : const QString & The new settings path.

init(info)​

Initilaizes the RtFiffRawView based on a FiffInfo.

Parameters:

  • info : QSharedPointer<FiffInfo> & The FiffInfo.
