QUESTION
I've started to create UI tests for my PyQt5 widgets using QtTest but have run into the following difficulties:
In order to speed up things, some of my widgets only perform operations when visible. As it seems that QtTest runs with invisible widgets, the corresponding tests fail.
For the same reason, I cannot test program logic that makes a subwidget visible under certain conditions.
Is there a way to make widgets visible during test? Is this good practice (e.g. w.r.t. CI test on GitHub) and is QtTest the way to go?
I have tried to use pytest with pytest-qt without success as I couldn't find a proper introduction or tutorial and I do know "Test PyQt GUIs with QTest and unittest".
Below you find a MWE consisting of a widget mwe_qt_widget.MyWidget with a combobox, a pushbutton and a label that gets updated by the other two subwidgets:
ANSWER
Answered 2021-Jun-15 at 17:01The problem is simple: QWidgets are hidden by default so isVisible() will return false, the solution is to invoke the show() method in init() to make it visible:
QUESTION
I'm currently working on a project running a jboss backend server (server-ear:ear exploded artefact) and a java gui (java 11) as frontend.
The backend contains a java service bean which accesses a database server and throws a custom exception (extends exceptions), if the variable is not found. The GUI catches the custom exceptions with a try and catch block.
The code is build and run inside of Intellij + Maven.
If i try to execute the code following arrow pops up at runtime:
...ANSWER
Answered 2021-Jun-15 at 10:54So for anyone interested what the problem was:
Since we are using a custom logger (ServiceLoggingInvocationHandler) which try catched the exceptions of an invoke method, the catched exceptions were already wrapped with an invocation exception and were not the original exceptions. To solve the problem we needed to unwrap the exceptions again before forwarding them.
Since the logger was only used in debugging mode and only when specified the problem was only occurring for me.
QUESTION
I build a script to filter several Messages out of a log file. The file im using right now has around 400.000 lines and when im looking for a match with the following code he takes very long since i added the progress bar. Is there a way to make it more efficient. If im right the reason for it to take so long is that he refreshes the progressbar Gui with every line he passes.
...ANSWER
Answered 2021-Jun-15 at 09:18Updating the progress bar element in the host application does indeed take up time and resources during execution - but even if you suppressed the progress bar, writing to the progress stream is still pretty slow!
As iRon suggests, the solution is to call Write-Progress less often:

Answered 2021-Jun-15 at 04:15Don't do that. Sqlite is a simple, in-memory, single-process database. If you need a database server, then use a database server. There are many choices.

QUESTION
I have a function to change an image and its opacity in a JavaFX GUI:
...ANSWER
Answered 2021-Jun-14 at 18:43In the meantime I found out that the reason for not changing the image is that I run changeImage() before the initialization of the GUI is completed. If I wait about 500 mS before I sent the changeImage() command all works fine.
Below is the minimal code that demonstrates the issue I had:
QUESTION
I wrote GUI using PySide2, numpy and matplotlib which works without any problm without problem on MacOS 11.2.3. However I get an error when running the code on Ubuntu 20.4 and The code works
I made a GUI using PySide2 and matplotlib. The goal is click on an image and store the coordinate of the clicks in a csv. After launching the application on Ubuntu and having clicked on the "button" button, I get an error message (provided after the code). It seems that under the Linux, the code is being run until line 91 (although no clicks where made on the image yet and therefore, the dataframe to store them is obviously empty) while on MacOS, the interpreter has stopped at line 76 waiting for the clicks of the user (on MacOS the picture has launched and there is nothing on the terminal)
Here is the code:
...ANSWER
Answered 2021-Jun-14 at 18:22I'm running on Windows, and your code has the same problem.
The first thing I noticed was that you do not have a backend specified. On my system clicking the button just shows an image without a GUI. In this situation there is nothing for click events to be connected to, and there is no GUI window to close.
I'm assuming on MacOS a plot figure shows up and lets you click on the graph several times. Once you close the graph print("ok1") is run. If this is the case plt.show() is blocking and waiting for the window to close. This is really a matplotlib issue. I tried running plt.show(block=True) which did not work with PySide2. There could be a PySide2 compatibility issue or a configuration file or the system setting causes different behavior.
The code below does checks if the figure.canvas is visible and blocks until it is closed.

I'm trying to use Apache Nutch 1.x Rest API. I use docker images to set up Nutch and Solr. You can see the demo repo in here
Apache Nutch uses Solr as its dependents. Solr works great, I'm able to reach its GUI at localhost:8983.
However, I cannot reach Apache Nutch's API at localhost:8081. The problem starts here. The Apache Nutch 1.X RESTAPI doc indicates that I can start the server like this
2. :~$ bin/nutch startserver -port [If the port option is not mentioned then by default the server starts on port 8081]
Which I am doing in docker-compose.yml file. I'm also exposing the ports to the outside.

QUESTION
I have written a GUI application in C++, built it for ARM processor and verified, that this application is running on Android in the Andronix emulated environment. Now is the question: How can I enable running this application on Android natively, without any emulated environment? I would like to create an APK file for installing it in a usual way. Are there any tools, which allow creating an APK file and packing an executable file into it?
...ANSWER
Answered 2021-Jun-14 at 11:32Andronix allows you to run Linux and and Linux executables in an environment separate to the native one - but if you want to run a linux executable on an android, you can do so with much simpler tools, like adb. For example, adb shell ./sdcard/my_app.pe would theoretically work.
However, APKs in android are basically zip files that include metadata, and the compiled code as a dex file. You would typically use a platform like Android Studio to generate them from java code.
If you really want to implement things from scratch you probably need to compile your application into a jar file, and then convert it to the dex file using a tool like d2j.
QUESTION
My GUI is able to play videos automatically when selected in the QListWidget. However, instead of normal speed, the videos play very fast. I use 720p Mp4 videos as examples and are placed in a certain folder. I tried using cv2.CAP_PROP_FPS and cv2.CAP_PROP_BUFFERSIZE, but they are both not working. I am using pyqtSignal in the QThread and the convert_cv_qt function which I saw in other guides. How do I play the videos in normal speed / frame rate?
ANSWER
Answered 2021-Jun-14 at 10:44When you use VideoCapture with a file if you call "cap.read()" you will obtain the next frame on the video, regardless of its actual framerate. Hence, you should use a "msleep" every time you capture a frame:

Install GUI
You can use GUI like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
