Question

我是tkinter的新手。我正在尝试构建一个从脚本启动的弹出表单，该脚本将提供多个复选框，以在关闭窗口后设置脚本中所需的变量。框架打开时我很好，但是我找不到将变量传递出去以备后用的方法。在下面的代码中，我想添加另一个按钮，该按钮将为varPDF和varSHP（全局？）设置这些变量，然后关闭窗口。

  var body = DocumentApp.getActiveDocument().getBody();
  var text = body.editAsText();
  body.clear();

  var tStart = 0;
  text.appendText("Check01\n\n");

  tEnde = body.editAsText().getText().length;
  body.editAsText().setFontSize(tStart, tEnde-1, 33);
  body.editAsText().setForegroundColor(tStart, tEnde-1, '#2E2EFE');
  body.editAsText().setBackgroundColor(tStart, tEnde-1, '#00FFFF');

  tStart = tEnde;
  text.appendText("Check01\n");
  tEnde = body.editAsText().getText().length;
  body.editAsText().setFontSize(tStart, tEnde-1, 22);
  body.editAsText().setForegroundColor(tStart, tEnde-1, '#00FFFF');
  body.editAsText().setBackgroundColor(tStart, tEnde-1, '#2E2EFE');

我设法找到了使用全局变量的解决方案，并设置了在单击复选框时对其进行设置的函数。它可能不是最优雅的解决方案，但它可以工作。

# show output variables
print('sVar: '+sVar)

窗口关闭后使用tkinter检查按钮值
