The QSize class defines the size of a two-dimensional object using integer point precision. A size is specified by a width and a height. It can be set in the constructor and changed using the setWidthsetHeightor scale functions, or using arithmetic operators. A size can also be manipulated directly by retrieving references to the width and height using the rwidth and rheight functions. Finally, the width and height can be swapped using the transpose function. The isValid function determines if a size is valid a valid size has both width and height greater than or equal to zero. The isEmpty function returns true if either of the width and height is less than, or equal to, zero, while the isNull function returns true only if both the width and the height is zero. Use the expandedTo function to retrieve a size which holds the maximum height and width of this size and a given size. Similarly, the boundedTo function returns a size which holds the minimum height and width of this size and a given size. See also setWidth and setHeight. Constructs a size with an invalid width and height i. See also expandedTo and scale. See also boundedTo and scale. See also width and setHeight. Returns true if either of the width and height is less than or equal to 0; otherwise returns false. See also isNull and isValid. See also isValid and isEmpty. Returns true if both the width and height is equal to or greater than 0; otherwise returns false. See also isNull and isEmpty. See also rwidth and setHeight. See also rheight and setWidth.

Attention: a port of PySide to Qt 5. The new API 2 provides automatic conversion between the Qt classes and respective native Python datatypes and is much more Pythonic in nature. PyQt on Python 2. Instead, you should simply use native Python datatypes. See e. PyQt unfortunately uses an implementation-specific naming scheme for its new-style signal and slot classes:. Signal and QtCore. Slot instead. If you want to modify your PyQt code to use the PySide naming scheme, that can be done using a simple definition:. Property instead of QtCore. PySide uses connect and event in the QObject. Do not use these for anything in your code, and when moving code from PyQt look for any that exist. In PySide you should. Otherwise you may receive. If a function is not present in PySide, check the Qt Online Reference Documentation and see whether the function has been deprecated and what to use instead. Example bug: bug For example, this affects functions such as QColor. If a lambda is used as a slot, sender cannot be used to acquire the object that emitted the signal. This works in PyQt, but their implementation behaves incorrectly in certain situations. See bug for details. PySide expects you to do the right thing:. Since this is an old and deprecated feature, and the effort to fix this is not worth it, we decided to not implement it. In PySide code you need to use something like:. You can check the complete discussion on bug The triggered signal will be connected to the slot handler instead of the triggered bool signal. It serves both to point out what differences exist as well as keeping your code binding-agnostic. This is important for when needing to support both bindings, usually when transitioning from one to the other and needing to continue to support older distributions that do not yet come with PySide. QtCore import QObject Furthermore it provides a substitute loadUi function for simple loading of ui files that work the same with both bindings. Jump to: navigationsearch.

The QPixmap class is an off-screen image representation that can be used as a paint device. More …. Inherited by: QBitmap. QBitmap is only a convenience class that inherits QPixmapensuring a depth of 1. The isQBitmap function returns true if a QPixmap object is really a bitmap, otherwise returns false. Finally, the QPicture class is a paint device that records and replays QPainter commands. QLabel has a pixmap property, whereas QAbstractButton has an icon property. QPixmap objects can be passed around by value since the QPixmap class uses implicit data sharing. For more information, see the Implicit Data Sharing documentation. QPixmap objects can also be streamed. Note that the pixel data in a pixmap is internal and is managed by the underlying window system. However, the fill function is available for initializing the entire pixmap with a given color. There are functions to convert between QImage and QPixmap. Typically, the QImage class is used to load an image file, optionally manipulating the image data, before the QImage object is converted into a QPixmap to be shown on screen. Alternatively, if no manipulation is desired, the image file can be loaded directly into a QPixmap. QPixmap provides a collection of functions that can be used to obtain a variety of information about the pixmap. In addition, there are several functions that enables transformation of the pixmap. QPixmap provides several ways of reading an image file: The file can be loaded when constructing the QPixmap object, or by using the load or loadFromData functions later on. Simply call the save function to save a QPixmap object. The complete list of supported file formats are available through the supportedImageFormats and supportedImageFormats functions. New file formats can be added as plugins. By default, Qt supports the following formats:. QPixmap provides a collection of functions that can be used to obtain a variety of information about the pixmap:. The hasAlphaChannel returns true if the pixmap has a format that respects the alpha channel, otherwise returns false. The hasAlphasetMask and mask functions are legacy and should not be used. They are potentially very slow. The createHeuristicMask function creates and returns a 1-bpp heuristic mask i. It works by selecting a color from one of the corners and then chipping away pixels of that color, starting at all the edges. The createMaskFromColor function creates and returns a mask i. The depth function returns the depth of the pixmap.

Please share with friends and colleagues! In the previous chapter we covered an introduction to the Model View architecture. In this tutorial we'll look at how to use QTableView from PyQt5, including how to model your data, format values for display and add conditional formatting. You can use model views with any data source, as long as your model returns that data in a format that Qt can understand. Working with tabular data in Python opens up a number of possibilities for how we load and work with that data. Here we'll start with a simple nested list of list and then move onto integrating your Qt application with the popular numpy and pandas libraries. This will provide you with a great foundation for building data-focused applications. QTableView is a Qt view widget which presents data in a spreadsheet-like table view. Like all widgets in the Model View Architecturethis uses a separate model to provide data and presentation information to the view. By customising the model it is possible to have a huge amount of control over how the data is presented. To use the model we'll need a basic application structure and some dummy data. A simple working example is shown below, which defines a custom model working with a simple nested-list as a data store. As in our earlier model view examples, we create the QTableView widget, then create an instance of our custom model which we've written to accept the data source as a parameter and then we set the model on the view. That's all we need to do — the view widget now uses the model to get the data, and determine how to draw it. For a table you need a 2D data structure, with columns and rows. As shown in the example above you can model a simple 2D data structure using a nested Python list. We'll take a minute to look at this data structure, and it's limitations, below —. The nested list is a "list of lists of values" — an outer list containing a number of sub-lists which themselves contain the values. With this structure, to index into individual values or "cells" you must index twice, first to return one of the inner list objects and then again to index into that list. The typical arrangement is for the outer list to hold the rows and each nested list to contain the values for the columns. Helpfully, this matches the visual layout in the source code. Note that using this type of structure you can't easily return an entire columnyou would instead need to iterate all the rows. However, you are of course free to flip things on their head and use the first index as column depending on whether accessing by column or row is more useful to you. Nothing about this data structure enforces equal row or column lengths — one row can be 5 elements long, another Inconsistencies can lead to unexpected errors on the table view. See the alternative data stores later if you're working with large or complex data tables. Next we'll look in a bit more detail at our custom TableModel and see how it works with this simple data structure to display the values. In the Model View Architecture the model is responsible for providing both the data and presentation metadata for display by the view. In order to interface between our data object and the view we need to write our own custom model, which understands the structure of our data. To write our custom model we can create a subclass of QAbstractTableModel. The only required methods for a custom table model are datarowCount and columnCount. The first returns data or presentation information for given locations in the table, while the latter two must return a single integer value for the dimensions of the data source. QAbstractTableModel is an abstract base class meaning it does not have implementations for the methods. If you try and use it directly, it will not work. You must sub-class it. The passed in data structure is stored by reference, so any external changes will be reflected here. To notify the model of changes you need to trigger the model's layoutChanged signal, using self. See the previous ModelView tutorial for more information. The data method is called with two values index and role.

VolumeSliderPhonon. SeekSliderPhonon. The PySide. QWidget class is the base class of all user interface objects. The widget is the atom of the user interface: it receives mouse, keyboard and other events from the window system, and paints a representation of itself on the screen. Every widget is rectangular, and they are sorted in a Z-order. A widget is clipped by its parent and by the widgets in front of it. A widget that is not embedded in a parent widget is called a window. Usually, windows have a frame and a title bar, although it is also possible to create windows without such decoration using suitable window flags. In Qt, PySide. QMainWindow and the various subclasses of PySide. QDialog are the most common window types. QWidget has many member functions, but some of them have little direct functionality; for example, PySide. QWidget has a font property, but never uses this itself. There are many subclasses which provide real functionality, such as PySide. QLabelPySide. QPushButtonPySide. QListWidgetand PySide. A widget without a parent widget is always an independent window top-level widget. For these widgets, PySide. Non-window widgets are child widgets, displayed within their parent widgets. Most widgets in Qt are mainly useful as child widgets. For example, it is possible to display a button as a top-level window, but most people prefer to put their buttons inside other widgets, such as PySide. The diagram above shows a PySide. QGroupBox widget being used to hold various child widgets in a layout provided by PySide. QLabel child widgets have been outlined to indicate their full sizes. If you want to use a PySide. QWidget to hold child widgets you will usually want to add a layout to the parent PySide. See Layout Management for more information. When a widget is used as a container to group a number of child widgets, it is known as a composite widget. These can be created by constructing a widget with the required visual properties - a PySide. QFramefor example - and adding child widgets to it, usually managed by a layout. The above diagram shows such a composite widget that was created using Qt Designer. Composite widgets can also be created by subclassing a standard widget, such as PySide. QWidget or PySide. QFrameand adding the necessary layout and child widgets in the constructor of the subclass. Many of the examples provided with Qt use this approach, and it is also covered in the Qt Tutorials. Since PySide. QWidget is a subclass of PySide.

Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. This is my first entry here so apologies for any newbie mistakes. I've searched both here and Google with no luck before posting. I want to be able to add images to a QListWidget, using drag and drop from a file browser. Dropping a valid file on the list widget also needs to trigger a function in the main class of my app, and pass it the image path. I found this code that does exactly that, but for PyQt4. There are no error messages. I think I've traced this to an old way of handling signals and have tried using the new, more pythonic way described here. I can't seem to get it working, while still passing a list of URLs between classes however. Found out how PySide signals work in the end. Here's the PyQt4 code above, ported to PySide. I'd love to hear if there are better solutions out there. This is not a drop signal, but a signal when the rows of a QListWidget have been moved. In my case this is always happening after dropping.

Hi there thimic I know this post is old, but this worked well for me but I dont quite understand how this works, do you know of a good explanation video or documentation that I could go through to understand it better? Hi there thimic So I have been trying to get a better understanding of this but I am struggling a little. Is there no way to just trigger an event like you do with button clicks? Are you wishing to be able to drag files onto the widget from outside and also re-arrange the items in the widget internally? JodyStocks, As for the other question, there are two concepts at play.
