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.

Attention: a port of PySide to Qt 5.x started in , the progress and more details about this project can be found under PySide 2. class GMain(QWidget,aracer.mobi_controlWindow). # def __init__(self). QWidget.__ init__(self,None) aracer.mobii(self) aracer.mobit(self. PySide software/pyqt/intro https://pypi. GNU GPL v3. LGPL. PyQt4, PyQt5. No Qt5.x support.

PySide 1. Although it is possible to only import the one that is needed, generally they are both needed and both imported. Note: the 'import' statement is not repeated in each code snippet below, it is assumed that it is already in the Python file. Yes QtGui. No, QtGui. 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. QPushButton "Option 1" option1Button. QPushButton "Option 2" option2Button. QPushButton "Option 3" option3Button. QPushButton "Option 4" option4Button. QPushButton "Option 5" option5Button.

The location of the ticks is determined by a Locator object and the ticklabel strings are formatted by a Formatter.

The combination of the correct Locator and Formatter gives very fine control over the tick locations and labels. This includes Text objects, Line2D objects, collection objects, Patch objects When the figure is rendered, all of the artists are drawn to the canvas. Most Artists are tied to an Axes; such an Artist cannot be shared by multiple Axes, or moved from one to another.

Classes that are 'array-like' such as pandas data objects and np. It is best to convert these to np. For example, to convert a pandas. DataFrame np. For functions in the pyplot module, there is always a "current" figure and axes which is created automatically on request.

For example, in the following example, the first call to plt. Use pyplot instead. For non-interactive plotting it is suggested to use pyplot to create the figures and then the OO interface for plotting.

These styles are perfectly valid and have their pros and cons. Just about all of the examples can be converted into another style and achieve the same results. The only caveat is to avoid mixing the coding styles for your own code. Note Developers for matplotlib have to follow a specific style and guidelines.

See The Matplotlib Developers' Guide. Of the different styles, there are two that are officially supported.

Therefore, these are the preferred ways to use matplotlib. For the pyplot style, the imports at the top of your scripts will typically be: import matplotlib. 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.

The Mouse Vs. The Python

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".
