Kivy:TextInput边框半径 [英] Kivy: TextInput border radius

I would like to know if it was possible in python & Kivy, to customize TextInput widgets like in HTML/CSS. Is there any way to do that directly into my CustomTextInput(TextInput) class ?

我希望我的TextInput看起来像这样:

I want my TextInput looks like this:

推荐答案

您当然可以，但是在kivy中则有些复杂:

Of course you can, but it's a bit more complicated in kivy:

test.kv :

#:import C kivy.utils.get_color_from_hex

<MyTextInput@TextInput>:
    font_size: '14dp'
    background_color: 0,0,0,0
    cursor_color: C('#ffffff')
    canvas.before:
        Color:
            rgba: C('#ffffff')
    canvas.after:
        Color:
            rgb: C('#0f192e')
        Ellipse:
            angle_start:180
            angle_end:360
            pos:(self.pos[0] - self.size[1]/2.0, self.pos[1])
            size: (self.size[1], self.size[1])
        Ellipse:
            angle_start:360
            angle_end:540
            pos: (self.size[0] + self.pos[0] - self.size[1]/2.0, self.pos[1])
            size: (self.size[1], self.size[1])
        Color:
            rgba: C('#3f92db')
        Line:
            points: self.pos[0] , self.pos[1], self.pos[0] + self.size[0], self.pos[1]
        Line:
            points: self.pos[0], self.pos[1] + self.size[1], self.pos[0] + self.size[0], self.pos[1] + self.size[1]
        Line:
            ellipse: self.pos[0] - self.size[1]/2.0, self.pos[1], self.size[1], self.size[1], 180, 360
        Line:
            ellipse: self.size[0] + self.pos[0] - self.size[1]/2.0, self.pos[1], self.size[1], self.size[1], 360, 540

python文件:

from kivy.app import App


class TestApp(App):
    pass

if __name__ == '__main__':
    TestApp().run()
