class hyperspyui.widgets.dataviewwidget.ComponentEditorHandler

Bases: Handler

setattr(info, object, name, value)

Handles the user setting a specified object trait’s value.

This method is called when an editor attempts to set a new value for a specified object trait attribute. Use this method to control what happens when a trait editor tries to set an attribute value. For example, you can use this method to record a history of changes, in order to implement an “undo” mechanism. No result is returned. The default implementation simply calls the built-in setattr() function. If you override this method, make sure that it actually sets the attribute, either by calling the parent method or by setting the attribute directly

Parameters:

info (UIInfo instance) – The UIInfo for the current UI
object (object) – The object whose attribute is being set
name (string) – The name of the attribute being set
value – The value to which the attribute is being set

class hyperspyui.widgets.dataviewwidget.DataViewWidget(main_window, parent=None)

Bases: QWidget

A custom QTreeWidget, that handles the Signal-Model-Component hierarchy. The relationships are displayed in a tree structure, and helps keep track of the relationships between them. Also makes handeling several Models per Signal easier.

ComponentType = 1002

ModelType = 1001

SignalType = 1000

_add(item, itemtype, parent=None): Make a QTreeWidgetItem for data item, and insert it below parent. The parent can be either a data item, or a QTreeWidgetItem.

_remove(key)

add(object, type, parent=None)

add_component(component, model)

add_model(model, signal=None)

add_signal(signal)

clear_editor()

currentItemChanged(current, previous)

edit_traits(comp, buttons=True)

get_selected_component()

get_selected_model(): Returns the first selected Model. Any selected Signals/Components will select their Model child/parent.

get_selected_wrapper(): Returns the first selected Signal. Any selected Models or Components will select their Signal parent.

get_selected_wrappers(): Returns a list of all selected signals. Any selected Models or Components will select their Signal parent.

itemDoubleClicked(item, column)

keyPressEvent(self, a0: QKeyEvent | None)

onCustomContextMenu(point): Displays the context menu for whatever is under the supplied point.

on_mdiwin_activated(mdi_figure): Can be connected to an MdiArea’s subWindowActivated signal to sync the selected signal.

remove(object)

set_traits_editor(traits_dialog)

class hyperspyui.widgets.dataviewwidget.HyperspyItem(parent, itemtype, hspy_item)

Bases: QTreeWidgetItem

_on_toggle_visibility()

data(self, column: int, role: int) → Any

setData(self, column: int, role: int, value: Any)

class hyperspyui.widgets.dataviewwidget.VisbilityDelegate(parent=None, icons=None)

Bases: QStyledItemDelegate

iconPos(icon, option)

paint(self, painter: QPainter | None, option: QStyleOptionViewItem, index: QModelIndex)

sizeHint(self, option: QStyleOptionViewItem, index: QModelIndex) → QSize

hyperspyui.widgets.dataviewwidget.tr(text)
