It's a pity PythonQt lacks proper documentation. I find this project very useful, and I think it deserves to be better documented. Hope, this will come some day :) My question is - is it possible to use pure cpp-objects (not subclasses of QObject) in the Python-part of PythonQt without wrapping them with QObject-derived classes? Say, I have a small cpp-class which represents an item in a collection, and I manipulate large lists of objects of this class. If for each object in a list I need a wrpper...

Hi All, I am new to the forums and I was wondering if someone could help me out with the issues I am having. I am trying to use the package, PythonQt here: https://mevislab.github.io/pythonqt/index.html to embedded a python script into a C++ Qt front end. I am having trouble building any of the examples sketches.

Ok, thank you. Distributing standard library and Python dll is ok for me, so I'll take up attempting to embed Python into my app with PythonQt.
-
Typically you will need to distribute the Python dll(s) and standard libraries together with your application, so that you have your own deployment of Python with your application. There will be a site-packages directory in the libs folder and users can install external Python libs using pip into your deployed Python installation. I would recommend copying the parts the you need from a standard Python installation into your application folder before building the installer. Python does not work without...

Hello, and first of all - thanks for this great project! I am developing an app using C++/Qt5, and thought about the possibility of third-party plugins by exposing Python APIs (similar to, e.g., as done in Sublime Text editor, although it is not based on Qt). Hence, I found that PythonQt might be exactly what I need. I've downloaded PythonQt and managed to compile/run examples, which look promising to me. However, there are some points which are not obvious from your documentation (at least to a...
-
removed methods that are not present on all platforms/configurations
-
applied patch from Uwe Siems (print correct file location in parser)
-
fixed QTimer wrapping for Qt 5.12
-
enable QMutexLocker (but __enter__ and __exit__ don't work yet due to PythonQt class wrapper implementation...)
-
enable QThread (it was removed long time ago but makes sense now that PythonQt support multi-threading)
-
don't print omitted rvalue methods, we just don't want to wrap them
-
applied patch provided by Uwe Siems

Florian, glad to see you are keeping a watch on things. I tried adding this line to the pp-qt-configuration file but it doesn't seem to have any affect. #define QT_DEPRECATED QT_DEPRECATED I would think that I should be able to set breakpoints in preprocessor.cpp but they never get called.
-
Look in the preprocessor code pr the master include, I guess one of them is defining it... or you have to add a define that defines it to itself, so that the preprocessor keeps it. On Fri 5.

I'm not having a lot of luck yet. I thought that I could add some code to check for QT_DEPRECATED on a function but it's not getting called. It seems that there is a pre-processor that is removing the QT_DEPRECATED token from the source. It looks like the prepocessor code is QT code that I can't see so I've been unable to see how it's doing this.

repo on github would be nice. makes it much easier to cooperate.

In the next couple of days, I should be able to take a look at some of the problems. What if I setup a repository on github for my changes? That should make it easier to shae any changes we make.
-
Me too. I already make a big part of our application scriptable, but the bugs that you mentioned produce a lot of trouble. Maybe we can cooperate to fix he bugs.
-
I only got involved with PythonQt because I wanted to add scripting capabilities to a QT program.
-
I also think that the endif warning is from an pythonqt parser bug. The strange thing is that i get it only when i add additional include directories. The parser sometimes does not see classes, but they are listed in the preprocess file. yeah, there are some weird bugs which need some checks. Do you use pythonqt only for qt stuff or do you use it for your own code as well (as i do)?
-
I don't believe that the "#endif without #if" problems are appearing because of a real poblem in the input header files but a bug in the PythonQT parser. It may be an indication of some classes not being processed properly. I sort of got sidetracked on other issues and haven't wlooked into any of these issues. At the present time, the failure od QSignalMapper as I previously posted about is my biggest concern. My next item of interest is figuring out how to ignore methods marked QT_DEPRECATED. Of...
-
Hey Allen C Kempe, I have the same troubles as you mentioned above. Does your last patch suggestion fix some of the above problems like #endif without #if or something like that? Greetings Tonka
-
You probably need to initialize PythonQtAll, because it contains the wrappers for QFrame. without generated wrappers, PythonQt can only provide the slots,signals and properties, but not methods that the moc does not handle. Calling PythonQtAll::init() before registering your class should do the trick. You could also pass in the name of the parent clas when registerings, but that is not really needed on Qobjects, I think.

Since you are entering Python from C++, you need to make sure that you hold the GiL, which you can do with placing the PYTHONQT_GIL_SCOPE into the scope where you communicate with Python or PythonQt (and even when you talk to a PythonQtObjectPtr, because it will do non-thread-safe ref counting of the PyObject). So you have to place PYTHONQT_GIL_SCOPE into your run method. An important thing to understand is that even it is multi threading, only one thread can talk to Python at a time, which is why...

In generator source file main.h, there is a check to see whether the QTDIR environment variable exists and a message is output to qWarning. It should also be output to stdout. Also, there is no check to verify that the directory specified exists. Further down, I found that "/QtWidgets" needs to be added to the list of includes in order to find QtClasses like QMainWindow. This eliminates the baseclass not found warnings. I'm wonderign whether the INCLUDES paths should also be verified that they e...

I've tricked this task by using queued signal and slots mechanism for GUI components that are going to be debugged. so the wrapped methods will just rise a signal and it'll catch it's appropriate method by pre-defined connections with Qt::AutoConnect so GUI components will decide how to connect to those relative slots based on the method they're running. (debug or just runeval) I know this is not a professional method for doing these stuff but it just satisfies my needs until now.

No, that is currently not implemented. You could expose non-QObject C++ objects and write wrappers/decorator classes for them. Or you could modify PythonQtClassInfo to stop inheritance traversal before QObject.

I think you have to look into remote debugging, e.g. like in PyDev /Eclipse or PyCharm. Running a debugger in the same process with Qt Gui is not possible, because the main thread will be blocked, so your Gui can't update. You need a second process which shows the Debugger and has a UI, typically that application is the text editor as well, so that you can set breakpoints and show where the cursor is located. Maybe using an existing remote debugger would be a simple solution for you (but less integrated...

Thank you Florian for your attention and reply I've managed somehow to make a debugger with PythonQt and bdb library of python. the problem is that bdb or other python debuggers are thread-based and if I use PythonQt_QtAll GUI elements it will be trapped in the thread of python I think and will crash out to desktop when stepping over script lines. do you have any suggestion for a way that I can manage it to work or any other efforts that I should follow maybe?

We developed our own TextEditor and Debugger using Qt. We use Jedi (in an extra process) for the autocompletion and goto definition etc. QSyntaxHighlighter for the highlighting... Debugger uses Python trace callbacks. Unfortunately it's all closed source. I dont't know a good open source option.

We are using PythonQT and QScintilla to provide simple tools to run and edit python scripts, but would really like a more powerful QT editor/debuggger component.

Hm, there are various ways, but all require some work, especially if you want to be able to modify the data from both sides... Maybe the easiest would be to use a Python array (see standard library) of the desired type. But PythonQt does not support automatic conversion, so you would need to use a PyObject pointer in your slot and use the Python C api to talk to it from C++. Another common way is to use numpy arrays, but that will require the numpy installation and you would need to use the numpy...

thanks, I want a way that each value change of variable in cpp function also applies to python. is there any way to do that?

You can't. You could change the interface to take a QVector or QList of ints. The any sequence in Python will be converted to that list/vector.

Hm, does your wrapper have a destructor slot (I forgot how they are named, delete_XYZ)? Because that is what PythonQt will use to destroy it (otherwise it can't destroy it).

Hmm, does not work as expected by myself. The slot has now a return type of PythonQtPassOwnershipToPython<PyBitView*> But the destructor of the PyBitView object is never called if i delete the object in python Is there still a reference hold by the wrapper object? I currently cannot find the source code line to start debugging on, perhaps you have an hint? Started from PythonQtSlot call. The result seems to have the right flags.

Is there any relation to PythonQt::init() i assume directly after PythonQt::init()
-
No, there is no such mechanism. PythonQt could have a callback to notify you when an object wrapper is deleted, but it would not know where the object came from.
-
Ok, understand. In my case i do not give the ownership to python currently, but i could. Then it would get deleted, and so my destructor is called. http://pythonqt.sourceforge.net/Developer.html in the section with ownership management the return type of my MyObject.get() slot could do this Question is if this is not the case, so if i do not WANT the object to be deleted, but used in python, CAN my object be INFORMED that the wrapper object is deleted? Or would this be a new feature?

-
The default ownership of returned objects is C++, so your object is not deleted by Python, just the wrapper to it. If your get() method returns a new object and you want Python to delete it, you can use the ownership templates in PythonQt.h http://pythonqt.sourceforge.net/classPythonQtPassOwnershipToPython.html#aaad0d16be54de03dbd53c5184f1318eb the templates don't do anything, but tell PythonQt that a returned pointer should change ownership.
