Align Label

[WS]

Hello everyone, I can justify the left (text_align='left') , the center (text_align='center'), but I can't justify the right (text_align='right'). Why is the limit - 1778?

from kivy.app import App

from kivy.uix.label import Label

from kivy.graphics import Color, Rectangle

class TitleLineWidget(Label):

def __init__(self, title, text_align='center', **kwargs):

super(TitleLineWidget, self).__init__(**kwargs)

self.text = title

self.text_align = text_align

self.bind(size=self.update_line)

with self.canvas.before:

Color(0.2, 0.7, 0.3, 1)

self.rect = Rectangle(pos=self.pos, size=self.size)

def update_line(self, instance, value):

if self.text_align == 'left':

self.text_size = (self.width - 40, self.height - 810)

self.text_pos = (self.x, self.center_y)

elif self.text_align == 'right':

self.text_size = (self.width - 1778, self.height - 810)

self.text_pos = (self.x, self.center_y)

class TitleLineApp(App):

def build(self):

title_line_widget = TitleLineWidget(title="text", text_align='right')

return title_line_widget

if __name__ == "__main__":

TitleLineApp().run()

To set the alignment of text within a Label you must set the text_size.  The text_size specifies the bounding box for the text.  You can then use valign and halign attributes to change the text alignment withing the text_size.

Read: https://kivy.org/doc/stable/api-kivy.uix.label.html#text-alignment-and-wrapping

Here is an example:

from kivy.app import App
from kivy.lang import Builder

kv = """
BoxLayout:
    orientation: 'vertical'
    AnchorLayout:
        Label:
            id: label
            size_hint: None, None
            size: dp(400), dp(400)
            text_size: self.size
            valign: 'center'
            halign: 'center'
            text: 'The Label Text'
            canvas.before:
                Color:
                    rgba: 0.2, 0.7, 0.3, 1
                Rectangle:
                    size: self.size
                    pos: self.pos
    BoxLayout:
        size_hint_y: None
        height: dp(48)
        Spinner:
            text: 'valign'
            values: ['bottom', 'center', 'top']
            on_text: label.valign = self.text
        Spinner:
            text: 'halign'
            values: ['auto', 'left', 'center', 'right', 'justify']
            on_text: label.halign = self.text
"""


class TextAlignmentApp(App):
    def build(self):
        return Builder.load_string(kv)


TextAlignmentApp().run()
