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

property value#

__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_item(self: open3d.cpu.pybind.visualization.gui.TreeView, item_id: int) → open3d.cpu.pybind.visualization.gui.Widget#: Returns the widget associated with the provided Item ID. For example, to manipulate the widget of the currently selected item you would use the ItemID of the selected_item property with get_item to get the widget.

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.
