My work on the Raspberry Pi is a hobby of sorts, in which I bring to bear nearly 50 years of writing software in some language on some computer. The little programs I wrote were games, in particular games to simulate landing on the moon Apollo was important, and still flying, back then.
That version of Python comes standard with the latest version of Raspbian, version 9. So I had a pretty good idea what Qt was capable of, especially the changes wraught by Qt4.
I tried to pull down the sources and build a local copy of Qt5 for myself, but since a single compile cycle for all of Qt takes multiple days building natively on the Pi, after going through two such back-to-back cycles trying to debug what the build failed on, I then turned to the Raspian repo versions of Python and PyQt5 and got on with my life. With Raspbian you have everything you need either installed directly or easily available via the repos.
Once those packages were installed I started to look around for some tutorials to help me get oriented with PyQt5. I found a site with lots of examples, and started to code my way up the learning curve. You can see some of those very primitive examples on the screen shot above. Of interest was a link on the site to download all the source. I figured I could rifle through the code for the interesting bits and build on that, but when I clicked on the link I was invited to buy the course in order to get the source code.
No thanks, so I went back and continued to copy-and-code. I may or may not put up my own set of tutorials that are clean, correct, and interesting.
If you have a Raspberry Pi and install PyQt5, then you should play with this and see what happens when you move tabs around or delete any of them, especially those with widgets. The tabs with widgets will clean up after themselves in my version. Search for: Close. Raspbian Desktop with running PyQt5 demo applications My work on the Raspberry Pi is a hobby of sorts, in which I bring to bear nearly 50 years of writing software in some language on some computer.
Setting tabs as closable displays a close button on each tab. Trust me when I say that my version works as advertised.
The signal-and-slot callbacks to execute when a tab was selected were never connected, and when I finally connected them, then they never worked.
I added the correct callbacks in lines 44 and On lines 26 and 27 of my version, setTabsClosable and and setMovable, were both set to True.There are many tutorials online for building Qt5 on the Raspberry Pi, but all or most of those tutorials are for using a desktop machine to cross compile the binaries for the Raspberry Pi.
You will not be able to run qmake and make on the Raspberry Pi itself if you cross compile. This tutorial is meant to show you how to natively compile Qt 5 on the Raspberry Pi so that you can use qmake and make on the Raspberry Pi itself without cross compiling or relying on an external desktop.
A more recent set of instructions for building Qt5 from a source tarball on a Raspberry Pi 2 is available here. First start off by obtaining either the latest version of Raspbian or the May 23rd version the one I used for this tutorial. Turn on your Raspberry Pi and log in. Make sure you have it connected properly to the internet and that you have a power supply that is at least 1A.
You may also want to overclock your Pi. I overclocked mine at MHz and it took 38 hours to compile and the temperature was a steady 51 C - 54 C with case, no heat-sinks, no fans.
Update 23th March for PI3, with latest version of Raspbian 4. Do not apply any patches that are available out there. They are no longer necessary with the latest Qt5. The git source should compile with a few tricks in the configure parameters without any patches. It should be below the above entries, you need to change the one in the else statement to this:. If you do not do this properly it will complain that it is not being cross compiled.
Do not be concerned with some things not building due to missing packages, there will be errors for those. If it does not mention that you can run make then check the last error, it is generally the show-stopper. Run configure:. Check the output file to see that it is building the components you need towards the end of the output it will have Yes next to the Qt Components that will be built and it should say that you can now run 'make'. Note, the compilation will take about two days to compile overclocked at MHz.
If you are logged in remotely consider using byobu or screen so that you can detach your session. After this you should be able to compile the sample applications and run them. Jump to: navigationsearch. This article may require cleanup to meet the Qt Wiki's quality standards.
Qt is now configured for building.

This is a 7 channel relay module, currently, I am using only 4 relays which are connected with the Raspberry Pi GPIO pins 26, 19, 13, and This relay module is powered up using a 12v Adaptor.
After you are done with all the settings, the next step is to install the PYQT5 software which is really simple. This is a good designing and programming practice to keep all your project files in one place. I started off by creating a folder for my project files. While you are on the Raspberry Pi desktop, right-click and select Create New and then click on the folder. I will save all my project files in this folder.

The Qt 5 designer software is very user-friendly; drag and drop the component you want to use. In my case, I am going to use a Pushbutton. Now, select a label, drag and drop it on the form.
Select a horizontal line from the left side components Widget Box, and drop it on the form, change the width of the line as per your requirement. This line is optional and is only used for designing purposes to make the application looks attractive. Select a Push Button Drag and drop it on the form. Change the dimensions of the Push Button as per your requirement. On the right side, you can see the Property Editor, you can change the width and height values, the X and Y axis values, then scroll down and set the font size, again scroll down until you see the text, click and delete the text PushButton.

PyQT5 Demo on Raspberry Pi
I followed the steps from your link. Today I found the solution. The steps below worked for me, without any error. The whole process took almost two hours. Learn more. Install PyQt5 on Raspberry for Python3. Asked 1 year, 1 month ago. Active 5 months ago. Viewed 4k times.
I use python3. Now I wanted to install the PyQt5 modul for python3. I usually use sudo python3. Trying sudo python3. So does anybody know how to use or install PyQt5 for the subsequently installed python3.
I think I am on the right way, but I do not understand what qmake is or what it means. I installed sudo apt-get install qt5-default Then I did the same procedure as already mentioned. Now I get the error fatal error: sip. Thanks guys. EGuy EGuy 63 1 1 silver badge 8 8 bronze badges.

This project is based on a Desktop monitor app named pkmeter, originally written by Michael Shepanski. The Pi Dashboard was started as a stand-alone GUI project, aiming to create a simple yet useful dashboard interface for small touch screen enabled devices like the Raspberry Pi using a display module add-on.
This initiated the idea to create one myself, with a Raspberry pi and the 7 inch screen. Pi Dashboard combined with the Netatmo weather plugin gives us all the info we need.
My test-unit runs with a smaller screen, a 5 inch WaveShare. The plugin system allows creating new meters quickly. I believe the following features are what makes this app different from the other solutions out there:. Allows one to use Font Awesome! Fonts in SVG format. It runs on any device supporting these including the Raspberry Pi.
It is designed for a resolution of x and is meant to be used with a touchscreen. Installing the PiDash on a Raspberry Pi with all prerequisites is quite simple.
However, I did walk into some trouble getting Python 3. They are not available in the current repositories. With a few hacks it is fixable though. After booting there are some on-screen instructions to follow.PyQt5 Project - Raspberry pi install and setup NOOBS - Raspbian
I created a standard user named pi. The following instructions assume that you have a raspberry pi running Raspbian with a small 5 inch xx LCD.
Without drivers, the screen works, but there is a yellow line visible on the left side of the screen, so its better to install the proper drivers for the display and of course to enable the touch function:.
Now you can calibrate the screen by starting the calibration app from the menu in Raspbian or from the Control Center in Ubuntu Mate. It will display the parameters you need to provide in the calibration config file:.Please note the user and login for the Linux image. To build on the Raspberry Pi we need a cross-compile toolchain.
The toolchain will contain compilers, linkers and other tools that run on the host workstation but create executables for the target Raspberry Pi. For embedded development, one normally uses a vendor-supplied toolchain, but in the case of the Raspberry Pi, there is no official vendor supplied toolchain. This is a Linaro based toolchain for the ARMv6 platform with hard floating-point support. Alternatively, we could have built our own toolchain. Our first step is to get and install a cross compiling toolchain.
Since this toolchain is built for bit systems, you will need a set of bit libraries installed if you are on a bit system. On Ubuntu systems, this can be accomplished by installing the ialibs package. Unfortunately, this is a deprecated transitional package, with no replacement. As a convenience, you can create a setdevenv.
We do this by burning a Raspbian image to an SD Card. Repeat: Make sure you know the correct device to use with the subsequent dd command, or you could lose all your data.
Additional packages will be needed on the Raspberry Pi in order to build Qt 5 and run Qt 5 applications. Here is a list of the basic packages needed for building and running Qt 5.
These are Ubuntu package names, but there should be similar packages on all Linux distros. Building software on the Raspberry Pi will be too slow, thus we will need to return to our workstation and use our cross-compile toolchain to perform the remainder of the work.
A traditional method of cross-platform development is to create a chroot or jail environment to build against. However, since we have a working image of the Raspberry Pi, we can use that instead and it will be much easier. Building Qt 5 will now proceed normally in much the same way as building Qt 5 for the desktop. There are a few minor differences however, such as applying a few patches and providing the appropriate configure options.
Repeat the following steps for each additional Qt module you wish to use: qtimageformatsqtjsbackendqtsvgqtxmlpatternsqtdeclarativeqtgraphicaleffectsqtmultimediaqtscriptqtwebkit. Note, the order of each build is important, as some modules are dependent on others.
