Key presses are used only when mouse mode is RectMode The following events are implemented: ctrl-A : zooms out to the default “full” view of the plot ctrl-+ : moves forward in the zooming stack (if it exists) ctrl– : moves backward in the zooming stack (if it exists)

keyReleaseEvent(self, event: Optional[QKeyEvent])

mouseClickEvent(ev: QEvent) → None

pyqtSignal(*types, name: str = …, revision: int = …, arguments: Sequence = …) -> PYQT_SIGNAL

types is normally a sequence of individual types. Each type is either a type object or a string that is the name of a C++ type. Alternatively each type could itself be a sequence of types each describing a different overloaded signal. name is the optional C++ name of the signal. If it is not specified then the name of the class attribute that is bound to the signal is used. revision is the optional revision of the signal that is exported to QML. If it is not specified then 0 is used. arguments is the optional sequence of the names of the signal’s arguments.

@param name: Name of the ROI @param sensible_roi: Sensible ROI object containing the ROI data @param args: Arguments to pass to the ROI object @param kwargs: Keyword arguments to pass to the ROI object

adjust_spec_roi(roi: SensibleROI) → None

as_sensible_roi() → SensibleROI

Converts the SpectrumROI to a SensibleROI object.

property colour: tuple[int, int, int, int]

contextMenuEnabled() → bool

property name: str

onChangeColor() → None

openColorDialog(current_color: QColor) → QColor

property roi: ROI

property selected_row: int | None

set_visibility(visible: bool) → None

Set the visibility of the ROI and its handles.

class mantidimaging.gui.windows.spectrum_viewer.spectrum_widget.SpectrumWidget(main_window: MainWindowView)

Bases: QWidget

The widget containing the spectrum plot and the image projection.

@param parent: The parent widget

add_roi(roi: SensibleROI, name: str) → None

Add an ROI to the image view.

@param roi: The ROI to add. @param name: The name of the ROI.

adjust_roi(new_roi: SensibleROI, roi_name: str) → None

Adjust the existing ROI with the given name. @param new_roi: The new SpectrumROI to replace the existing SpectrumROI @param roi_name: The name of the existing ROI.

change_roi_colour(name: str, colour: tuple[int, int, int, int]) → None

Change the colour of an existing ROI

cleanup() → None

colour_generator() → tuple[int, int, int, int]

A random colour generator to colour ROIs boarders. Generates colours that are easy to see for colour blind people if colour_blind_friendly is True. By default colour_blind_friendly is set to False

@return: A random colour in RGBA format. (0-255, 0-255, 0-255, 0-255)

get_roi(roi_name: str) → SensibleROI
