This is my first time trying to build a simple GUI and i am a little stuck on how to split the windows within each tab. So far i have made a simple gui interface using wxPython that contains 5 tabs which lead to a different pages essentially. What i am trying to do is once you have clicked on one of the tabs the screen is in two parts one side containing filters and the other side is to be used to view graphs or a refined dataset . I have created the static text that i want displayed on the left but do not know how to put it in its own window on the left side of the application. I have the code i have been using below and if anybody can help me that would be great.
