Greetings All, I am a software developer starting a project for a biology lab doing work in protein structure. I am not a biologist. We'll be using Pymol as the basis for the visualization component of the application, and I am at the beginning stages of understanding how pymol works and is put together.
I already have a number of questions but I am going to hold off until I have more experience with the package. But there is one issue I need settled soon and I'm hoping some of you can point me in the right direction. We are not going to use the existing external UI or the internal GLUT UI. Our application will be doing a bunch of things not related to 3-D structure, and my thinking right now is to simply start pymol in a separate thread as it is done in examples/devel/start_pymol.py, handing it the -x and -i flags. Then our app will use cmd.* calls to get protein structures loaded and manipulated. What I don't understand is how I can get notified of events that happen when the user uses the mouse to select residues etc. For example, once a protein is loaded, our app may color certain residues if we know that there have been experiments that mutated that position(s). And if a user clicks on one of those residues, our app needs to open up another window and present the data by fetching it from a relational database. Is there a way that the external GUI can be notified of events? I looked through the documentation and didn't see anything obvious. I looked through the code a bit, and I'm still at a very early stage of learning. But I did see that the pmg_tk module sets pymol._ext_gui and sets up a FIFO. I can't see that it is used anywhere by the pymol module, but I'm thinking that this is the start of a 2-way communication mechanism between pymol and an external GUI? Can anyone tell me how to be notified that selections change? Or even just receive raw mouse events? Thanks! ---- Bob Terek The Quarry, Inc. http://www.thequarry.com/ rte...@thequarry.com
