PygameXtras 1.3.9

Labels, Buttons, and much more for pygame

PygameXtras

PygameXtras is a library designed to make programming with pygame easier. It supplies classes that aim at reducing the time and effort that go into everyday tasks like displaying text, creating buttons, managing entry forms, etc.

Example

import pygame
import PygameXtras as px

pygame.init()
screen = pygame.display.set_mode((500, 600))
clock = pygame.time.Clock()

circle_center = (350, 350)
circle_radius = 50

mouse_radius = 70
color = "blue"

line_y = 260

buttons = [
    px.Button(
        screen,
        c,
        25,
        (15 + i * 140, 15),
        "topleft",
        fd=(125, 40),
        bw=3,
        br=10,
        hl=True,
        bgc=c,
    )
    for i, c in enumerate(("purple", "green", "blue"))
]

label_touching = px.Label(screen, "not touching", 16, (0, 0), tc="red")
label_distance = px.Label(screen, "distance: n/a", 30, (25, 75), "topleft", tc=0)

entry = px.Entry(
    screen,
    "",
    25,
    (15, 135),
    "topleft",
    fd=(200, 40),
    bgc=150,
    bw=3,
    br=10,
    twe="custom color",
    ast=True,
)

while True:
    events = pygame.event.get()
    for event in events:
        if event.type == pygame.QUIT:
            pygame.quit()
            exit()

    for button in buttons:
        if button.update(events):
            color = button.backgroundcolor

    entry.update(events)
    if entry.get_state():
        entry.update_colors(bordercolor="blue")
    else:
        entry.update_colors(bordercolor="black")
    if entry.get() != "":
        try:
            color = px.parsers.Color.parse(entry.get())
        except:
            pass

    mouse_pos = pygame.mouse.get_pos()
    mouse_pos = (mouse_pos[0], max(line_y, mouse_pos[1]))
    if px.Collisions.circle_circle(
        mouse_pos, mouse_radius, circle_center, circle_radius
    ):
        label_touching.update_text("touching")
        label_touching.update_colors(textcolor="lime")
    else:
        label_touching.update_text("not touching")
        label_touching.update_colors(textcolor="red")
    label_touching.update_pos(mouse_pos)
    label_distance.update_text(
        f"distance: {max(0, round(px.get_distance(mouse_pos, circle_center) - mouse_radius - circle_radius, 1))} px"
    )

    screen.fill((20, 90, 20))
    pygame.draw.circle(screen, (128, 128, 128), circle_center, circle_radius)
    pygame.draw.circle(screen, color, mouse_pos, mouse_radius)
    pygame.draw.line(
        screen, (0, 0, 0), (0, line_y - mouse_radius), (500, line_y - mouse_radius)
    )
    label_touching.draw()
    label_distance.draw()
    for button in buttons:
        button.draw()
    entry.draw()

    pygame.display.flip()
    clock.tick(120)

Label arguments

Labels (any classes inheriting from Label) can be styled using keyword arguments. The tables given below list all positional and keyword arguments and their specific uses. Please note: The types Color, Coordinate, PositiveInt, PositiveFloat, Size2 and Size4 refer to any values which are successfully digested by their respective parser (found in PygameXtras.parsers).

Positional arguments for Labels

name	type	info	default
surface	pygame.Surface, None	the surface which the Label should be drawn to	-
text	Any	the text displayed on the Label	-
size	PositiveFloat	the size of the displayed text	-
xy	Coordinate	the pixel coordinates of the Label	-
anchor	str	the point within the Label which should be bound to the xy coordinate, similar to pygame.Rects positioning system	"center"

Keyword arguments for Labels

The last column, "LBE", shows for which widget (L = Label, B = Button, E = Entry) which keyword is relevant.

long	short	type	info	default	LBE
textcolor	tc	Color	sets the textcolor	(0,0,0)	LBE
backgroundcolor	bgc	Color	sets the backgroundcolor, transparent if set to None	None	LBE
antialias	aa	bool	whether antialiasing should be used	True	LBE
font	f	str	font style (to see all built-in fonts, run PygameXtras.get_fonts())	verdana	LBE
x_axis_addition	xad	PositiveInt	adds pixels to the background of the label along the x axis	0	LBE
y_axis_addition	yad	PositiveInt	adds pixels to the background of the label along the y axis	0	LBE
borderwidth	bw	PositiveInt	sets the borderwidth	0	LBE
bordercolor	bc	Color	sets the bordercolor	(0,0,0)	LBE
force_width	fw	PositiveInt	sets the width of the Label to the given size	None	LBE
force_height	fh	PositiveInt	sets the height of the Label to the given size	None	LBE
force_dim	fd	Size2	sets the width and the height of the Label to the given size	None	LBE
borderradius	br	PositiveInt, Size4	sets the borderradius	1	LBE
text_offset	to	Coordinate	offsets the text within the Label by the given amount	(0,0)	LBE
image	img	pygame.Surface	sets the background of the Label to be the image given	None	LBE
info	info	Any	can be used to attach any information to the Label	None	LBE
text_binding	tb	str	binds the text to a location within the Label (similar to anchor)	center	LBE
highlight	hl	bool, Color	highlights the Button if the cursor touches it	None	BE
active_area	aA	Size4	limits the Button functionality to an absolute area (any clicks on the button while it is outside of the given area are not registered)	None	BE
bold	bo	bool	sets text styling to bold	False	LBE
italic	it	bool	sets text styling to italic	False	LBE
underline	ul	bool	sets text styling to underline	False	LBE
one_click_manager	ocm	OneClickManager	suppresses clicks if a different Button has already been clicked	None	BE
template	t	dict	injects style keywords from the given template	None	LBE
margin	m	PositiveInt, Size4	adds a margin that decreases the size of the Label without affecting its position	None	LBE
font_file	ff	str	sets the font of the Label to the given font	None	LBE
text_align	ta	str	sets the text alignment when text is wrapped (for example using \n or force_width)	center	LB
