python layout/functionality questions <p>I am about to start making a python (2.7) app - using wx, but im still having a few theoretical walls infront, making me sceptical about practical success.</p> <p>So below are a few questions: 1) My app will have many widgets (buttons, entries, labels, comboboxes) - where the majority will be added when the user invokes some events (clicking Add button will create additional labels, entries, comboboxes and buttons). My question here is, how can i keep track of this dynamic content, i sure wish to have a delete option aswell. My best guess was lists, but im still not sure how can i handle something like a combobox + im kinda lost on how could i delete a group of widgets.</p> <p>2) which practice of widget placement would be best for a fixed size frame/panels? Would be manual setting of xypos be just fine? Even considering my questions in 1) - mainly interested how to handle layout if something in the middle of frame gets deleted - holes would not be nice.</p> <p>Many thanks</p>
