open3d.visualization.gui.TreeView#

class open3d.visualization.gui.TreeView#

Hierarchical list

class Constraints#

Constraints object for Widget.calc_preferred_size()

__init__(self: open3d.pybind.visualization.gui.Widget.Constraints) → None#

property height#

property width#

class EventCallbackResult(value, names=<not given>, *values, module=None, qualname=None, type=None, start=1, boundary=None)#

Returned by event handlers

__init__(*args, **kwds)#

as_integer_ratio()#

Return a pair of integers, whose ratio is equal to the original int.

The ratio is in lowest terms and has a positive denominator.

>>> (10).as_integer_ratio()
(10, 1)
>>> (-10).as_integer_ratio()
(-10, 1)
>>> (0).as_integer_ratio()
(0, 1)

bit_count()#

Number of ones in the binary representation of the absolute value of self.

Also known as the population count.

>>> bin(13)
'0b1101'
>>> (13).bit_count()
3

bit_length()#

Number of bits necessary to represent self in binary.

>>> bin(37)
'0b100101'
>>> (37).bit_length()
6

conjugate()#: Returns self, the complex conjugate of any int.

from_bytes(byteorder='big', *, signed=False)#

Return the integer represented by the given array of bytes.

bytes: Holds the array of bytes to convert. The argument must either support the buffer protocol or be an iterable object producing bytes. Bytes and bytearray are examples of built-in objects that support the buffer protocol.
byteorder: The byte order used to represent the integer. If byteorder is ‘big’, the most significant byte is at the beginning of the byte array. If byteorder is ‘little’, the most significant byte is at the end of the byte array. To request the native byte order of the host system, use `sys.byteorder’ as the byte order value. Default is to use ‘big’.
signed: Indicates whether two’s complement is used to represent the integer.

is_integer()#: Returns True. Exists for duck type compatibility with float.is_integer.

to_bytes(length=1, byteorder='big', *, signed=False)#

Return an array of bytes representing an integer.

length: Length of bytes object to use. An OverflowError is raised if the integer is not representable with the given number of bytes. Default is length 1.
byteorder: The byte order used to represent the integer. If byteorder is ‘big’, the most significant byte is at the beginning of the byte array. If byteorder is ‘little’, the most significant byte is at the end of the byte array. To request the native byte order of the host system, use `sys.byteorder’ as the byte order value. Default is to use ‘big’.
signed: Determines whether two’s complement is used to represent the integer. If signed is False and a negative integer is given, an OverflowError is raised.

denominator#: the denominator of a rational number in lowest terms

imag#: the imaginary part of a complex number

numerator#: the numerator of a rational number in lowest terms

real#: the real part of a complex number

__init__(self: open3d.pybind.visualization.gui.TreeView) → None#: Creates an empty TreeView widget

add_child(self: open3d.pybind.visualization.gui.Widget, arg0: open3d.pybind.visualization.gui.Widget) → None#: Adds a child widget

add_item(self: open3d.pybind.visualization.gui.TreeView, arg0: SupportsInt, arg1: open3d.pybind.visualization.gui.Widget) → int#: Adds a child item to the parent. add_item(parent, widget)

add_text_item(self: open3d.pybind.visualization.gui.TreeView, arg0: SupportsInt, arg1: str) → int#: Adds a child item to the parent. add_text_item(parent, text)

calc_preferred_size(self: open3d.pybind.visualization.gui.Widget, arg0: open3d.pybind.visualization.gui.LayoutContext, arg1: open3d.pybind.visualization.gui.Widget.Constraints) → open3d.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.pybind.visualization.gui.TreeView) → None#: Removes all items

get_children(self: open3d.pybind.visualization.gui.Widget) → list[open3d.pybind.visualization.gui.Widget]#: Returns the array of children. Do not modify.

get_item(self: open3d.pybind.visualization.gui.TreeView, item_id: SupportsInt) → open3d.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.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.pybind.visualization.gui.TreeView, arg0: SupportsInt) → None#: Removes an item and all its children (if any)

set_on_selection_changed(self: open3d.pybind.visualization.gui.TreeView, arg0: collections.abc.Callable[[SupportsInt], None]) → None#: Sets f(new_item_id) which is called when the user changes the selection.

property background_color#: Background color of the widget

property can_select_items_with_children#: If set to False, clicking anywhere on an item with will toggle the item open or closed; the item cannot be selected. If set to True, items with children can be selected, and to toggle open/closed requires clicking the arrow or double-clicking the item

property enabled#: True if widget is enabled, False if disabled

property frame#: The widget’s frame. Setting this value will be overridden if the frame is within a layout.

property selected_item#: The currently selected item

property tooltip#: Widget’s tooltip that is displayed on mouseover

property visible#: True if widget is visible, False otherwise
