After reading this tutorial, you will be able to program nontrivial PySide applications. PySide is Python library to create cross-platform graphical user interfaces. Tutorials for other GUI Python bindings include PyQt4 tutorial, wxPython tutorial, PyGTK tutorial and Tkinter. Dr. Jibo He is an avid developer using Python, PySide, and Qt. He has over know that Packt offers e-book versions of every book published, with PDF and The PySide documentation wiki page. API reference manuals. Tutorials . PySide is the Python Qt bindings project, providing access the complete Qt . Throughout this tutorial, we are only using Homebrew, because it.

For very simple things like this example, the only advantage is academic: the wordier styles are more explicit, more clear as to where things come from and what is going on. For more complicated applications, this explicitness and clarity becomes increasingly valuable, and the richer and more complete object-oriented interface will likely make the program easier to write and maintain.
Typically one finds oneself making the same plots over and over again, but with different data sets, which leads to needing to write specialized functions to do the plotting. Some people use matplotlib interactively from the python shell and have plotting windows pop up when they type commands. Some people run Jupyter notebooks and draw inline plots for quick data analysis.
Others embed matplotlib into graphical user interfaces like wxpython or pygtk to build rich applications. Some people use matplotlib in batch scripts to generate postscript images from numerical simulations, and still others run web application servers to dynamically serve up graphs.
To support all of these use cases, matplotlib can target different outputs, and each of these capabilities is called a backend; the "frontend" is the user facing code, i.
There are two types of backends: user interface backends for use in pygtk, wxpython, tkinter, qt4, or macosx; also referred to as "interactive backends" and hardcopy backends to make image files PNG, SVG, PDF, PS; also referred to as "non-interactive backends". There are four ways to configure your backend.
PySide – Introduction – part 001
If they conflict each other, the method mentioned last in the following list will be used, e. If your script depends on a specific backend you can use the use function: import matplotlib matplotlib. Calling use after pyplot has been imported will have no effect. Using use will require changes in your code if users want to use a different backend. Therefore, you should avoid explicitly calling use unless absolutely necessary.
Note Backend name specifications are not case-sensitive; e. If, however, you want to write graphical user interfaces, or a web application server Matplotlib in a web application server , or need a better understanding of what is going on, read on. To make things a little more customizable for graphical user interfaces, matplotlib separates the concept of the renderer the thing that actually does the drawing from the canvas the place where the drawing goes.
All of the user interfaces except macosx can be used with agg rendering, e.
Remember that even if the user enters only digits, "" for example, they are strings and must be converted to number representation with either of the following:. The final Beginner Level example is of how to build a dialog with an arbitrary number of buttons. This example is programmatically too complex to be invoked from a single Python statement so in some ways it should be on the next page which is PySide Medium examples. But on the other hand this is often all that is needed without getting into complex GUI definitions, so the code is placed at the end of the page of this Beginner PySide page rather than the beginning of the following Medium PySide page.
Each piece of code under test would be in a function with the name 'routine1 ', 'routine2 ', etc. As many buttons as you can fit on the screen may be used.
Follow the patterns in the code sample and add extra buttons as needed - the Dialog box will set it's width accordingly, up to the width of the screen. To put them into a vertical line, change the line of code to read:. Jump to: Other languages:.QPushButton "Option 1" option1Button. For very simple things like this example, the only advantage is academic: the wordier styles are more explicit, more clear as to where things come from and what is going on.
At this level, the user uses pyplot to create figures, and through those figures, one or more axes objects can be created. For example, to convert a pandas. Search inside document.
Edit: Since it appears this question is getting some views, I thought I'd come back and add a few of what I found to be the most useful tutorials on PyQt. As many buttons as you can fit on the screen may be used. IJAR Journal. Window only BitTorrent py2exe.
