interactive

I've created a simple python script that when run should display an embedded matplotlib graph inside a PyQT window. I've used this tutorial for embedding and running the graph. Aside from some differences in the naming conventions and in the overall UI my graph is generated exactly as the one in the tutorial mentioned. My problem is that I would like to make this an interactive graph that allows for zooming and dragging, but I would like to do this with only the mouse (clicking and dragging, scroll wheel, etc) and without the toolbar (as I find it ugly). Widget Class: class MplCanvas

I need to run my Python script as usual, but I want to stop execution on a specific line and start interactive mode. In other words, I want to be able to check the value of all my variables at that point, and continue myself from there on python's command line. How can I do this? This can be done with the code module. The easiest way is to call code.interact() . Use a debugger and add breakpoints. Do you use an IDE? All the major IDEs have debugger support. From the CLI, you can use pdb . Not exactly what you're looking for, but you can easily have your program break out to pdb (the Python

I wish to do lua prog.lua arg1 arg2 from the command line Inside prog.lua, I want to say, for instance print (arg1, arg2, '\n') Lua doesn't seem to have argv[1] etc and the methods I've seen for dealing with command line arguments seem to be immature and / or cumbersome. Am I missing something? You're missing the arg vector, which has the elements you want in arg[1] , arg[2] , and so on: % lua -i -- /dev/null one two three Lua 5.1.3 Copyright (C) 1994-2008 Lua.org, PUC-Rio > print(arg[2]) two > More info in the Lua manual section on Lua standalone (thanks Miles!). daurnimator In addition to

I'd like to do a small program in R for interactive visualization and modification of some raster datasets, seen as colored images. The user should open a file (from the terminal it's OK), plot it, select the points to edit with mouse clicks, and insert the new values. So far I achieved that easily. I use the plot() function from the raster package to visualize the plot, then click() to select the points and edit their value via the terminal. I'd like to add the ability to show the values on mouse over. I've searched for ways on how to do this, but this doesn't seem to be possible with the

I want to make an interactive transition between a ViewController (1) and a NavigationViewController (2). The NavigationController is called by a button, so there's no interactive transition when presenting. It can be dismissed by a button or a UIPanGestureRecognizer, so it can be dismissed interactively or not. I have an object named TransitionManager for the transition, subclass of UIPercentDrivenInteractiveTransition. The problem with the code below is that the two delegate methods interactionControllerFor... are never called. Moreover, when I press the buttons or swip

I'd like to do something like: do lots of stuff to prepare a good environement become_interactive #wait for Ctrl-D automatically clean up Is it possible with python?If not, do you see another way of doing the same thing? With IPython v1.0, you can simply use from IPython import embed embed() with more options shown in the docs . Use the -i flag when you start Python and set an atexit handler to run when cleaning up. File script.py: import atexit def cleanup(): print "Goodbye" atexit.register(cleanup) print "Hello" and then you just start Python with the -i flag: C:\temp>\python26\python -i

I'm looking for a library that will layout and display graphs (i.e. network diagrams, not charts) in 3D, with some interactivity like selecting and dragging nodes, rotating the display etc. I would like to do this in a web page so Javascript or Flash are preferable, I'd also consider Java. Having looked myself I realise the options are very limited so I'm interested to hear of any such libraries regardless of language or interactivity, even if they don't run in a browser. 3D is essential though, there are other questions on this site convering 2D libraries. Update: please, stop adding details
