如何修复窗户上出现美学故障的Kivy缩放比例？

标签： python windows kivy

有没有办法使缩放的Kivy窗口在美学上令人愉悦？

默认情况下，当使用Kivy缩放窗口时，似乎窗口的内容随着窗口的缩放而拉伸，从而导致像素化混乱。只有释放窗口后，它才能正确呈现内容。

翘曲示例

我正在Windows中运行它。包含完整的点子列表

如果要运行它，这是我的代码。尝试缩放窗口，您应该会看到污点（如果我的kivy安装没有问题）

main.py

from kivy.app import App
from kivy.uix.gridlayout import GridLayout
from kivy.properties import ObjectProperty

from kivy.config import Config
Config.set('input', 'mouse', 'mouse,multitouch_on_demand')

class CalcGridLayout(GridLayout):
    display = ObjectProperty(None)

    def calculate(self, calculation):
        if calculation:
            try:
                self.display.text = str(eval(calculation))
            except Exception:
                self.display.text = "you MORON"

class CalculatorApp(App):

    def build(self):
        return CalcGridLayout()

calcApp = CalculatorApp()
calcApp.run()
