mantidimaging.gui.widgets.zslider.zslider module

class mantidimaging.gui.widgets.zslider.zslider.ZSlider

Bases: PlotItem

A plot item to draw a z-axis slider mimicking the slider in PyQtGraph’s ImageView

This gives us flexibility to choose what happens when the user move through the z-axis. It can be combined with the one or more MIMiniImageView’s in a GraphicsLayoutWidget. It is used in the Operations window to choose the slice to preview a filter with, and in the Live Viewer scroll through images.

Emits a valueChanged signal when the user moves the slider

mousePressEvent(ev: QGraphicsSceneMouseEvent) → None

Adjusts built in behaviour to allow user to click anywhere on the line to jump there.

set_range(min: int, max: int) → None

set_value(value: int) → None

valueChanged

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.

value_changed() → None

z_line: InfiniteLine
