Because of this, the GUI manages SubsetGroups, and presents each group to the user as a single entity. The individual subsets are held in-sync by the SubsetGroup.

Client code should only create Subset Groups via glue.core.data_collection.DataCollection.new_subset_group(). It should not call add_subset() or new_subset() directly

glue.viewers.matplotlib.mouse_mode Module

MouseModes define various mouse gestures.

MouseModes are generally activated and deactivated by toolbar buttons, although not necessarily so. The toolbar maintains a list of MouseModes from the visualization it is assigned to, and sees to it that only one MouseMode is active at a time.

Each MouseMode appears as an Icon in the toolbar. Classes can assign methods to the press_callback, move_callback, and release_callback methods of each Mouse Mode, to implement custom functionality

The basic usage pattern is thus:

  • visualization object instantiates the MouseModes it wants

  • each of these is passed to the add_tool method of the toolbar

  • visualization object optionally attaches methods to the 3 _callback methods in a MouseMode, for additional behavior

Classes

glue.utils.qt.widget_properties Module

The classes in this module provide a property-like interface to widget instance variables in a class. These properties translate essential pieces of widget state into more convenient python objects (for example, the check state of a button to a bool).

Example Use:

class Foo(object):
    bar = ButtonProperty('_button')

    def __init__(self):
        self._button = QtWidgets.QCheckBox()

f = Foo()
f.bar = True  # equivalent to f._button.setChecked(True)
assert f.bar == True

Classes

WidgetProperty(att[, docstring])

Base class for widget properties

CurrentComboDataProperty(att[, docstring])

Wrapper around the data in QComboBox.

CurrentComboTextProperty(att[, docstring])

Wrapper around the text in QComboBox.

CurrentTabProperty(att[, docstring])

Wrapper around QTabWidget.

TextProperty(att[, docstring])

Wrapper around the text() and setText() methods for QLabel etc

ButtonProperty(att[, docstring])

Wrapper around the check state for QAbstractButton widgets

FloatLineProperty(att[, docstring])

Wrapper around the text state for QLineEdit widgets.

ValueProperty(att[, docstring, value_range, log])

Wrapper around widgets with value() and setValue()

Plugins
