Textinput making strange indent not as label with same settings

I am trying to put textinput and label with same settings in one place so text would be at same place but textinput making strange indent while label doesnt.

I am calculating height of text with limited width using label's function _label.texture.size and then applying this height and width to text input and label expecting two textes would be in same place for accurate label's text selection. But im getting this, firstly all is good but then text in textinput makes strange indent and all text then goes wrong. Result: My problem

Code:


from kivy.app import App
from kivy.uix.label import Label
from kivy.uix.textinput import TextInput
from kivy.uix.floatlayout import FloatLayout

class main(App):

    def build(self):


        f = FloatLayout()




        text = "This is random text Every time you're online, you are bombarded by pictures, articles, links and videos trying to tell their story. Unfortunately, not all of these stories are true. Sometimes they want you to click on another story or advertisement at their own site, other times they want to upset people for political reasons. "
        labeltocheckheight = Label(text=text, text_size=(200, None), markup=True,font_size="24", size=(400, 100), pos=(100, 100), size_hint=(1, 1), valign='top')

        labeltocheckheight._label.refresh()
        width, height = labeltocheckheight._label.texture.size
        
        label = Label(text=text, text_size=(width, height), markup=True,font_size="24", size=(width, height), pos=(100, 100), size_hint=(None, None), valign='top')
        textinput2 = TextInput(text=text, font_size="24", size=(width, height), cursor=(0,0),pos=(100, 100), size_hint=(None, None), readonly=True, foreground_color=(1, 1, 1, 0.5),background_color=(1, 0, 0, 0), padding=0)


        f.add_widget(textinput2)
        f.add_widget(label)




        return f





main().run()
Solution

  • The Label and the TextInput use different algorithms for wrapping text, so it is not likely that they will agree. You can process the text from the labeltocheckheight, extracting the individual lines, then setting them as the text for the TextInput. Here is a modified version of your build() method that uses this approach:

    def build(self):
    f = FloatLayout()

    text = "This is random text Every time you're online, you are bombarded by pictures, articles, links and videos trying to tell their story. Unfortunately, not all of these stories are true. Sometimes they want you to click on another story or advertisement at their own site, other times they want to upset people for political reasons. "
    labeltocheckheight = Label(text=text, text_size=(200, None), markup=True,font_size="24", size=(400, 100), pos=(100, 100), size_hint=(1, 1), valign='top')

    labeltocheckheight._label.refresh()
    width, height = labeltocheckheight._label.texture.size

    text_for_ti = ''
    num_line = len(labeltocheckheight._label._cached_lines)
    for line_num in range(num_line):
        line = labeltocheckheight._label._cached_lines[line_num]
        if line_num == num_line - 1:
            text_for_ti += line.words[0].text
        else:
            text_for_ti += line.words[0].text + '\n'


    label = Label(text=text, text_size=(width, height), markup=True,font_size="24", size=(width, height), pos=(100, 100), size_hint=(None, None), valign='top')
    textinput2 = TextInput(text=text_for_ti, font_size="24", size=(width, height), cursor=(0,0),pos=(100, 100), size_hint=(None, None), readonly=True, foreground_color=(1, 1, 1, 0.5),background_color=(1, 0, 0, 0), padding=0)


    f.add_widget(textinput2)
    f.add_widget(label)

    return f

    The only difference is the calculation of text_for_ti, and the use of that for the text property of the TextInput. You might want to add do_wrap=False to the TextInput.
