Bases: UILayout

Places children based on anchor values.

Defaults to size_hint = (1, 1).

Supports the options size_hint, size_hint_min, and size_hint_max. Children are allowed to overlap.

Child are resized based on size_hint. size_hint_min/max only take effect if a size_hint is set.

Allowed keyword options for add():

  • anchor_x: str = None

    Horizontal anchor position for the layout. The class constant default_anchor_x is used as default.

  • anchor_y: str = None

    Vertical anchor position for the layout. The class constant default_anchor_y is used as default.

  • align_x: float = 0

    Horizontal alignment for the layout.

  • align_y: float = 0

    Vertical alignement for the layout.

add(child: W, *, anchor_x: str | None = None, align_x: float = 0, anchor_y: str | None = None, align_y: float = 0, **kwargs) → W[source]#

Add a widget to the layout as a child. Added widgets will receive all user-interface events and be rendered.

By default, the latest added widget will receive events first and will be rendered on top of others. The widgets will be automatically placed within this widget.

Parameters:

  • child – Specified child widget to add.

  • anchor_x – Horizontal anchor. Valid options are left, right, and center.

  • align_x – Offset or padding for the horizontal anchor.

  • anchor_y – Vertical anchor. Valid options are top, center, and bottom.

  • align_y – Offset or padding for the vertical anchor.

class arcade.gui.UIBoxLayout(x=0, y=0, width=0, height=0, vertical=True, align='center', children: Iterable[UIWidget] = (), size_hint=(0, 0), size_hint_min=None, size_hint_max=None, space_between=0, style=None, **kwargs)[source]#

Bases: UILayout

Place widgets next to each other. Depending on the vertical attribute, the widgets are placed top to bottom or left to right.

Hint

UIBoxLayout does not adjust its own size if children are added. This requires a UIManager or a UIAnchorLayout as a parent.

Or use arcade.gui.UIBoxLayout.fit_content() to resize the layout. The bottom-left corner is used as the default anchor point.

Supports the options: size_hint, size_hint_min, size_hint_max.

If a child widget provides a size_hint for a dimension, the child will be resized within the given range of size_hint_min and size_hint_max (unrestricted if not given). If the parameter vertical is True, any available space (layout size - min_size of children) will be distributed to the child widgets based on their size_hint.

Parameters:

  • x – x coordinate of the bottom left corner.

  • y – y coordinate of the bottom left corner.

  • vertical – Layout children vertical (True) or horizontal (False).

  • align – Align children in orthogonal direction:: - x: left, center, and right - y: top, center, and bottom

  • children – Initial list of children. More can be added later.

  • size_hint – Size hint for the UILayout if the widget would like to grow. Defaults to 0, 0 -> minimal size to contain children.

  • size_hint_min – Minimum width and height in pixels.

  • size_hint_max – Maximum width and height in pixels.

  • space_between – Space in pixels between the children.

do_layout()[source]#

Bases: UILayout

Place widgets in a grid layout. This is similar to tkinter’s grid layout geometry manager.

Defaults to size_hint = (0, 0).

Supports the options size_hint, size_hint_min, and size_hint_max.

Children are resized based on size_hint. Maximum and minimum size_hint``s only take effect if a ``size_hint is given.

Parameters:

  • x – x coordinate of bottom left corner.

  • y – y coordinate of bottom left corner.

  • align_horizontal – Align children in orthogonal direction. Options include left, center, and right.

    print(event.old_value, event.new_value)
Parameters:

Bases: UIWidget

An input field the user can type text into. This is useful in returning string input from the user. A caret is displayed, which the user can move around with a mouse or keyboard.

A mouse drag selects text, a mouse press moves the caret, and keys can move around the caret. Arcade confirms that the field is active before allowing users to type, so it is okay to have multiple of these.

Parameters:

  • x – x position (default anchor is bottom-left).

  • y – y position (default anchor is bottom-left).

  • width – Width of the text field.

  • height – Height of the text field.

  • text – Initial text displayed. This can be modified later programmatically or by the user’s interaction with the caret.

  • font_name – A list of fonts to use. Arcade will start at the beginning of the tuple and keep trying to load fonts until success.

  • font_size – Font size of font.

  • text_color – Color of the text.

  • multiline – If enabled, a \n will start a new line. A UITextWidget multiline of True is the same thing as a UITextArea.

  • caret_color – RGB color of the caret.

  • size_hint – A tuple of floats between 0 and 1 defining the amount of space of the parent should be requested.

  • size_hint_min – Minimum size hint width and height in pixel.

  • size_hint_max – Maximum size hint width and height in pixel.

  • style – Style has not been implemented for this widget, however it will be added in the near future.

Bases: UIWidget

A simple text label. This widget is meant to display user instructions or information. This label supports multiline text.

Parameters:

  • x – x position (default anchor is bottom-left).

  • y – y position (default anchor is bottom-left).

  • width – Width of the label. Defaults to text width if not specified. See content_width().

  • height – Height of the label. Defaults to text height if not specified. See content_height().

  • size_hint_min – Minimum size hint width and height in pixel.

  • size_hint_max – Maximum size hint width and height in pixel.

  • width – width of widget

  • height – height of widget

  • size_hint – Tuple of floats (0.0-1.0), how much space of the parent should be requested

do_render_base(surface: Surface)[source]#

Renders background, border and “padding”

move(dx=0, dy=0)[source]#

Move the widget by dx and dy.

Parameters:

  • dx – x axis difference

  • dy – y axis difference

on_event(event: UIEvent) → bool | None[source]#

Passes UIEvent s through the widget tree.

on_update(dt)[source]#

Custom logic which will be triggered.

prepare_render(surface)[source]#

Helper for rendering, the drawing area will be adjusted to the own position and size. Draw calls have to be relative to 0,0. This will also prevent any overdraw outside of the widgets area

Parameters:

surface – Surface used for rendering

remove(child: UIWidget)[source]#

Removes a child from the UIManager which was directly added to it. This will not remove widgets which are added to a child of UIManager.

resize(*, width=None, height=None)[source]#
scale(factor)[source]#

Scales the size of the widget (x,y,width, height) by factor. :param factor: scale factor

trigger_full_render() → None[source]#

In case a widget uses transparent areas or was moved, it might be important to request a full rendering of parents

trigger_render()[source]#

This will delay a render right before the next frame is rendered, so that UIWidget.do_render() is not called multiple times.

with_background(*, color=Ellipsis, texture: None | Texture | NinePatchTexture = Ellipsis) → UIWidget[source]#

Set widgets background.

A color or texture can be used for background, if a texture is given, start and end point can be added to use the texture as ninepatch.

Parameters:

  • color – A color used as background

  • texture – A texture or ninepatch texture used as background

Returns:

self

with_border(width=2, color=(0, 0, 0)) → Self[source]#

Sets border properties :param width: border width :param color: border color :return: self

with_padding(top=Ellipsis, right=Ellipsis, bottom=Ellipsis, left=Ellipsis, all=Ellipsis) → UIWidget[source]#

Changes the padding to the given values if set. Returns itself :return: self
