Question

我有两台显示器。如果我运行我的项目，它将出现在主监视器上。我可以通过以下方式调整窗口大小并使其全屏显示： - ＆GT;单击右上角的全屏按钮 - ＆GT;将它拉到屏幕顶部

与Microsoft-Windows一样。

但是如果我在第二个窗口中拉我的应用程序，这会改变。通过单击全屏图标，或将其拉到顶部，我将收到以下错误消息：

这是一个小样本，仅用于演示我的问题：

from kivy.config import Config
Config.set('kivy', 'exit_on_escape', '0')
from kivy.app import App
from kivy.uix.label import Label
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.button import Button
from kivy.uix.popup import Popup
from kivy.core.window import Window
from kivy.properties import ObjectProperty, ListProperty, StringProperty
from kivy.logger import Logger


class ChildApp(App):


    def __init__(self, sys_path_list=None):
        super(ChildApp, self).__init__()
        # Hotkey
        self.superkey = []
        text = StringProperty()
        keyboard = Window.request_keyboard(self._keyboard_released, self)
        keyboard.bind(on_key_down=self._keyboard_on_key_down, on_key_up=self._keyboard_released)


    def _keyboard_released(self, *args):
        self.superkey = []


    def _keyboard_on_key_down(self, window, keycode, text, super):
        if 'lctrl' in self.superkey and keycode[1] == 's':
            Logger.info('DO SOMETHING')
            self.superkey = []
            return False
        elif 'lctrl' not in self.superkey and keycode[1] in ["lctrl"]:
            self.superkey.append(keycode[1])
            return False
        else:
            Logger.info("key {} pressed.".format(keycode))
            return False


    def build(self):
        Window.bind(on_request_close=self.on_request_close)
        return Label(text='Child')


    def on_request_close(self, *args):
        Logger.info('Are you sure?')
        return True


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

在添加按键功能之前，我能够在两台显示器上全屏显示。你能告诉我怎么能在两台显示器上全屏显示它？

Answer 1

我编辑了以下文件的第1141行：

C：\ Python34 \ LIB \站点包\ kivy \芯\ window__init __吡啶

行：

targettop = max(0, target.to_window(0, target.y)[1]) if target else 0

编辑为：

if target and 'to_window' in dir(target):
    targettop = max(0, target.to_window(0, target.y)[1])
else:
    targettop = 0

在第二台显示器上听键和全屏
