Kivy TextInput on_double_tap
提问于 2013-10-25 16:49:43
我已经添加了一个文本输入窗口到我的Kivy应用程序，我试图用窗口做两件事。默认情况下，文本输入窗口突出显示双击的单词。我想把这个单词存储到一个变量中，而不知道如何将它从输入窗口传递给变量。第二，我试图从操作系统中剪切并粘贴到Kivy中，但无法理解。任何帮助都将不胜感激。这是我到目前为止的代码。谢谢你帮助我走到这一步。
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()

只需像下面这样重写您的on_double_tap方法。
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使用粘贴函数。您不应该直接使用它们，kivy负责处理这个问题，只需使用ctrl + c，x，v。
