ui file we've created ( mainwindow.ui) creates the window and starts up the application. To view the resulting UI, we can use the standard application template below. This shows the entire image at all times, although it does not respect the aspect ratio of the image if you resize the widget. You can add the full path to the gif or have it in the same. When scaledContents is enabled the image is resized to the fit the bounding box of the QLabel widget. Screenshot is a frozen shot, but gif is animated and plays in the window. In the same controls panel, click to enable scaledContents. You need to resize the QLabel to be able to see the entire image. ![]() From the property editor dropdown select "Choose File…" and select an image file to insert.Īs you can see, the image is inserted, but the image is kept at its original size, cropped to the boundaries of the QLabel box. For this tutorial we will create an image using PyQt Designer and then change them image source from our python code. Next, with the Label selected, look in the right hand QLabel properties panel for the pixmap property (scroll down to the blue region). Drag this onto the QMainWindow to add it. You can find Label at in Display Widgets in the bottom of the left hand panel. Using Qt Designerįirst, create a MainWindow object in Qt Designer and add a "Label" to it. Below we'll look at how to use QLabel to display a widget in your applications. The primary use of QLabel is of course to add labels to a UI, but it also has the ability to display an image - or pixmap - instead, covering the entire area of the widget. The widget you use to display an image is QLabel. Also note that you must have at least one QObject created beneath it for this to work. source image processing app, started as an experimental port of GIMP to use Qt instead of. Instead you should assign a layout to the root object/widget (pointing to the aforementioned image, it should be the MainWindow instead of centralWidget). In Qt you can fit a widget to full screen size using Qts API. QML type from Qt Quick Controls, it will automatically calculate the window size based on the sizes of its content items. ![]() Since you're wanting to insert an image you might be expecting to use a widget named QImage or similar, but that would make a bit too much sense! QImage is actually Qt's image object type, which is used to store the actual image data for use within your application. The accepted answer (its image) is wrong, at least now in QT5. In this short tutorial, we will look at how you can insert an external image into your PyQt5/Pyside2 application layout, using both code and Qt Designer. Unfortunately, because of how this is done in Qt, it can be a little bit tricky to work out at first. ![]() Adding images to your application is a common requirement, whether you're building an image/photo viewer, or just want to add some decoration to your GUI.
