Question

我在我的Kivy APP中添加了一个文本输入窗口，我正在尝试用窗口做两件事。默认情况下，文本输入窗口会突出显示双击的单词。我想将该单词存储到变量中，并且无法弄清楚如何将它从输入窗口传递给变量。其次，我试图将操作系统剪切并粘贴到Kivy中，但无法弄明白。任何帮助将非常感激。这是我到目前为止的代码。感谢Inclement帮助我做到这一点。

Builder.load_string('''

<MouseWidget>:
    image: image
    label: label
    orientation: 'vertical'
    Image:
        id: image
        source: root.source
    Label:
        id: label
        size_hint_y: None
        height: 50
        text: 'Test'
''')

class MouseWidget(BoxLayout):
    image = ObjectProperty()
    label = ObjectProperty()
    source = StringProperty()


    def on_touch_down(self, touch):
        if self.image.collide_point(*touch.pos):
            trigger = 0
            if touch.x >= 133 and touch.x <= 646 and touch.y >= 162 and touch.y <=675:
            self.label.text = str(touch.pos)


    def on_touch_up(self, touch):
        self.label.text = 'This is a test'



class TESTApp(App):
    def build(self):
        root = Accordion(orientation='horizontal')

        item= AccordionItem(title='Test')
        src = "image.png"
        image = MouseWidget(source=src, size_hint = (1.0, 1.0))

        textinput = TextInput(text='Hello world', size_hint = (0.5, 1.0))
        textinput.bind(text2 = on_double_tap())


        # add image to AccordionItem
        item.add_widget(image)
        item.add_widget(textinput)
        root.add_widget(item)

    return root

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

只需覆盖您的on_double_tap方法，如下所示。

from kivy.app import App
from kivy.uix.textinput import TextInput
from kivy.clock import Clock


class Test(TextInput):

    def on_double_tap(self):
        # make sure it performs it's original function
        super(Test, self).on_double_tap()

        def on_word_selection(*l):
            selected_word = self.selection_text
            print selected_word
            # do what you want with selected word here

        # let the word be selected wait for
        # next frame and get the selected word
        Clock.schedule_once(on_word_selection)

class TestApp(App):

    def build(self):
        return Test()


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

对于复制和粘贴TextInput支持ctrl + x，c，v，内部TextInput使用_cut, _copy and _paste functions。您不应该直接使用它们kivy会为您解决这个问题，只需使用ctrl + c，x，v。
