启用和禁用按钮

Question

我正在 Python 中开发一个应用程序，我想将一组特定的按钮设置为禁用，直到首先单击另一个按钮。例如，当我按下 Sim Card 按钮时，我希望将 Sim Report 按钮设置为启用。

我曾尝试使用此解决方案实现该功能：但它只会禁用按钮 5 秒钟。我只想在相应按钮满足条件时启用特定按钮。除非首先基本解析数据，否则我不想生成报告。

Answer 1

您可以使用 button.setEnabled(False) 或 button.setEnabled(True) 启用和禁用按钮。至于什么时候启用，只要在上面适当的地方加上两行就可以触发按钮了。

因此，以您的示例为例，从禁用 simReport 按钮开始。然后在您的 select_sim_data 函数中，添加 generate_Sim_Report.setEnabled(True)。您可以在任何需要控制按钮是否启用的方法中实现此功能。
