我试图在气泡中为Kivy中的TextInput显示数字键盘。可能吗?
到目前为止,我有:
Builder.load_string('''
<NumericKeyboard>
size_hint: (None, None)
size: (160, 120)
pos_hint: {'center_x': .5, 'y': .6}
BubbleButton:
text: 'Cut'
BubbleButton:
text: 'Copy'
BubbleButton:
text: 'Paste'
''')
class NumericKeyboard(Bubble):
pass
class CustomTextInput(TextInput):
def __init__(self, **kwargs):
super(CustomTextInput, self).__init__(**kwargs)
def on_focus(self, instance, value):
self.bubb = NumericKeyboard()
self.add_widget(self.bubb)
但是气泡不会显示。
最佳答案
是的,可以使用Kivy Bubble for TextInput小部件显示数字键盘。有关详细信息,请参见以下示例。
注意:文本输入未过滤。
例
main.py
from kivy.app import App
from kivy.uix.floatlayout import FloatLayout
from kivy.uix.bubble import Bubble, BubbleButton
from kivy.uix.label import Label
from kivy.properties import ObjectProperty
from kivy.lang import Builder
class CustomBubbleButton(BubbleButton):
pass
class NumericKeyboard(Bubble):
layout = ObjectProperty(None)
def __init__(self, **kwargs):
super(NumericKeyboard, self).__init__(**kwargs)
self.create_bubble_button()
def create_bubble_button(self):
numeric_keypad = ['7', '8', '9', '4', '5', '6', '1', '2', '3', '', '0', '.']
for x in numeric_keypad:
if len(x) == 0:
self.layout.add_widget(Label(text=""))
else:
bubb_btn = CustomBubbleButton(text=str(x))
self.layout.add_widget(bubb_btn)
class BubbleShowcase(FloatLayout):
text_input = ObjectProperty(None)
def show_bubble(self, *l):
if not hasattr(self, 'bubb'):
self.bubb = bubb = NumericKeyboard()
self.bubb.arrow_pos = "bottom_mid"
self.add_widget(bubb)
Builder.load_file("test.kv")
class TestBubbleApp(App):
title = "Numeric Key Pad - Using Bubble"
def build(self):
return BubbleShowcase()
if __name__ == '__main__':
TestBubbleApp().run()
