Question

我已经制作了以下代码来执行在QtDesigner中制作的表格并转换为'.py'文件。我的问题是，当我执行代码时，它并没有真正显示表单，但没有消息错误，它在工具栏上显示一个python图标，如果它正在运行表单，我尝试从cmd启动它。 exe，但同样的事情发生.PD：我使用Sublime Text 3和Python 3.4.4。请帮忙，谢谢！

    form = Form3()
    form.show()

Answer 1

尝试更改

MainWindow.setWindowOpacity(-1.0)

到

MainWindow.setWindowOpacity(1.0)

来自http://doc.qt.io/qt-4.8/qwidget.html#windowOpacity-prop 不透明度的有效范围是从1.0（完全不透明）到0.0（完全透明）。

我在使用Python 2.7.11+的Ubuntu上尝试了你的代码并获得了与你相同的结果

它并没有真正显示表单，但没有消息错误在工具栏上显示一个python图标，就好像它正在运行表单
一样

但改变这一行修复了问题

更新：刚刚在Windows 10，Python 3.4.4，PyQt4，Sublime build 3103上尝试过它。它可以使用更新的代码行，甚至可以从Sublime（使用Ctrl + B）开始，只需提供两个文件一个变化。

PyQt4表单未启动
