class EventCallbackResult

Returned by event handlers

Members:

IGNORED : Event handler ignored the event, widget will handle event normally

HANDLED : Event handler handled the event, but widget will still handle the event normally. This is useful when you are augmenting base functionality

CONSUMED : Event handler consumed the event, event handling stops, widget will not handle the event. This is useful when you are replacing functionality

CONSUMED = EventCallbackResult.CONSUMED

HANDLED = EventCallbackResult.HANDLED

IGNORED = EventCallbackResult.IGNORED

__init__(self: open3d.cpu.pybind.visualization.gui.TreeView) → None

Creates an empty TreeView widget

add_child(self: open3d.cpu.pybind.visualization.gui.Widget, arg0: open3d.cpu.pybind.visualization.gui.Widget) → None

Adds a child widget

add_item(self: open3d.cpu.pybind.visualization.gui.TreeView, arg0: int, arg1: open3d.cpu.pybind.visualization.gui.Widget) → int

Adds a child item to the parent. add_item(parent, widget)

add_text_item(self: open3d.cpu.pybind.visualization.gui.TreeView, arg0: int, arg1: str) → int

Adds a child item to the parent. add_text_item(parent, text)

calc_preferred_size(self: open3d.cpu.pybind.visualization.gui.Widget, arg0: open3d.cpu.pybind.visualization.gui.LayoutContext, arg1: open3d.cpu.pybind.visualization.gui.Widget.Constraints) → open3d.cpu.pybind.visualization.gui.Size

Returns the preferred size of the widget. This is intended to be called only during layout, although it will also work during drawing. Calling it at other times will not work, as it requires some internal setup in order to function properly

clear(self: open3d.cpu.pybind.visualization.gui.TreeView) → None

Removes all items

get_children(self: open3d.cpu.pybind.visualization.gui.Widget) → List[open3d.cpu.pybind.visualization.gui.Widget]

Returns the array of children. Do not modify.

get_root_item(self: open3d.cpu.pybind.visualization.gui.TreeView) → int

Returns the root item. This item is invisible, so its child are the top-level items

remove_item(self: open3d.cpu.pybind.visualization.gui.TreeView, arg0: int) → None

Removes an item and all its children (if any)

set_on_selection_changed(self: open3d.cpu.pybind.visualization.gui.TreeView, arg0: Callable[[int], None]) → None

Sets f(new_item_id) which is called when the user changes the selection.
