wxpython 按钮被阻止/不点击答案

【问题标题】：wxpython buttons blocked/not clickingwxpython 按钮被阻止/不点击

【问题描述】：

点击不会触发事件。

我正在为python中的简单数据可视化制作一个简单的GUI

似乎有什么东西挡住了按钮和选择，实际上是主面板中的任何东西。

它正在工作，但后来我从 matplotlib 中放入了图表我怀疑这与展示位置/盒子大小有关，但我一生都无法弄清楚。

非常感谢任何帮助。

【问题讨论】：

我怀疑您使用编辑器对该代码执行了错误的find and replace。您的代码中完全缺少许多函数/变量。您需要先解决这个问题，然后才能让任何人弄清楚它到底出了什么问题。

【解决方案1】：

您从不将面板添加到 sizer，因此它可能与 FigureCanvas 重叠。

此外，最好不要长时间创建并保持对话。只需根据需要创建它们以显示它们，然后在获取它们的值后Destroy。
