大家好,大约 3 天以来,我一直在努力解决这个问题!我有一个完美运行的 wxFrame 以及一个完美运行的 ReportLab pdf 脚本。分别参见下面的代码文件(注意:data1.py 是 GUI,而 data2.py 是正在运行的 pdf 脚本)。我的问题是:- 1)我希望 pdf 脚本仅在按下“保存到 PDF”按钮后运行 2)名称字段的值(存储在变量“NameString”中)应添加到生成的 pdf文件。
目前,如果我运行脚本(data2.py),它会同时创建 Frame 和 pdf 文件(不包括“NameString”)。这不是我想要的,我希望只有在单击/按下“保存到 PDF”按钮后才能打开 pdf 并包含“NameString”。
在此先感谢您的时间。
