Grid

SimpleKivy.SimpleKivy.Grid(layout=[[]], k=None, navigation_behavior=False, **kwargs)

Dynamic BoxLayout constructor.

Dynamic Creation Parameters

navigation_behavior: bool

Whether the widget will have GridNavigationBehavior.

Experimental feature. See GridNavigationBehavior for more details.

Parameters

layout: list (matrix-like)

Matrix of widgets used to fill a Grid-type layout. Any missmatch between the lengths of each row is compensated with Void widgets.

• list: [[Widget, Widget, ...],[Widget, ...], ...]: List of lists. Each element of the list represents a row of widgets.

Example:

sk.Grid(layout = [
    [sk.Label('a_11')],
    [sk.Label('a_21'), sk.Label('a_22')],
    ])

k: None, str, or NOTKEY

Key specification for quick acess:

• None: Automatically sets an int value.

• str: Use specific string key.

• NOTKEY: Special flag indicating no key should be used.

size: str or sequence of 2 ints

Size specification of the widget:

• str: "x{width}": Sets widget width and size_hint_x = None.

• str: "y{height}": Sets widget height and size_hint_y = None.

• str: "xchildren": Sets size_hint_x = None and binds this widget’s width to the sum of the widths of its children.

• str: "ychildren": Sets size_hint_y = None and binds this widget’s height to the sum of the heights of its children.

• str: "xchild_max": Sets size_hint_x = None and binds this widget’s width to the child with the maximum width.

• str: "ychild_max": Sets size_hint_y = None and binds this widget’s height to the child with the maximum height.

You can combine up to two of the above size string specifications.

• str: "{number}": Processed as size = (number, number) and size_hint = (None,None). Cannot be combined with other string specifications.

• sequence: (int, int): Size of the widget. Same as Kivy. Has no effect if size_hint argument is not set to None.

Example:

sk.Grid(size = "y35")
sk.Grid(size = "x120y35")
sk.Grid(size = "xchildreny40")
sk.Grid(size = "xchildrenychildren")
sk.Grid(size = "xchild_maxy40")
sk.Grid(size = "60")
sk.Grid(size = (120,35), size_hint = (None, None))

enable_events: bool

Whether the widget will send events to the event_manager set in MyApp using the widgets k/id property as event identifier.

• True: Triggers events.

• False: Doesn’t trigger events.

on_event: str, iterable (tuple or list), dict

Defines which events/property changes will trigger the event_manager. Only has effect if enable_events = True.

• str: Name of the event or property that will trigger the event_manager.

• iterable: [str, str, ...]: Will trigger events for each name in the iterable.

• dict: {"{event_name}": callback}: Calls instance.bind(**on_event) during widget creation.

Example:

sk.Grid(enable_events = True, on_event = 'width')
sk.Grid(enable_events = True, on_event = 'on_touch_down')
sk.Grid(enable_events = True, on_event = ['width','height','pos'])
sk.Grid(enable_events = True, on_event = {"size": lambda ins,v: print("size =",v)})

do_dot_subevent: bool

Adds a “.” to describe the event when triggering the event_manager.

• True: The event identifier is str(widget.id)+".{event_name}".

• False: The event identifier is the same as the widget’s k/id.

Default is False.

bcolor, lcolor and any other valid properties with color in their name can be specified with sequence or str during creation:

• sequence: [float, float, float, float]: Sequence (list or tuple) of 4 float numbers (0.0-1.0). Same as Kivy.

• str: "{hex_string}": Hex color in the format "#000000".

• str: "{named_color}": Name of a color from the List of Named Colors supported by SimpleKivy.

bcolor: Background color of the widget.

lcolor: Line color of the widget.

lwidth: number (float or int)

Width of the widget’s border line.

Returns

GridLayout created dynamically with layout widgets added as children during creation.
