@SGaist said in 'str' object has no attribute 'chop': Hi, You write your code as if you where using QString objects. With either PySide2 or PyQt5 you'll have Python str objects. You need to translate these bits. rrrrrrright, Duh! I'm still kind of new to writing Qt in Python... changing my code to using pin[:-1] works as expected! Thanks!

Hi, To add a layout to a layout there's the "addLayout" method.

In the PyQt 4.9.4 code downoaded from https://sourceforge.net/projects/pyqt/files/PyQt4/ I find (Note that we are using 4.9.3 but I couldn't find the sources of that version) void sipQLineEdit::changeEvent(QEvent *a0) { sip_gilstate_t sipGILState; PyObject *sipMeth; sipMeth = sipIsPyMethod(&sipGILState,&sipPyMethods[14],sipPySelf,NULL,sipName_changeEvent); if (!sipMeth) { QLineEdit::changeEvent(a0); return; } typedef void (*sipVH_QtCore_17)(sip_gilstate_t,PyObject *,QEvent *); ((sipVH_QtCore_17)(sipModuleAPI_QtGui_QtCore->em_virthandlers[17]))(sipGILState,sipMeth,a0); }

@jsulm When the pop up Message Box shows "python has stopped working", I clicked "debug" rather than close, then visual studio was started, in visual studio, it shows Unhandled exception at 0x0000000059A17DF1 (QtGui4.dll) in python.exe: 0xC000041D: An unhandled exception was encountered during a user callback I was using pycharm to trace code step by step, however it nev, aer run to this issue by step by step since there are two many small steps/callback/signal/slot to go through, as long as I let it run without breakpoint, it will crash with segmentation fault.

By default a QComboBox reads and saves its currentText property when being mapped to a data model column. I wonder if this is causing your problem?

The module name is PyQt4 case sensitive.

@SGaist said in QProcess event queue: Hi, Unless you put that in a loop, readLine will only read one line each time. One thing you can do is split the content of trace_output on the carriage return and parse each element after that. Sry didn't get notified about your reply. I have managed to solve this using subprocess module on a different thread. Would like to see it working with QProcess too though. Did you find any bug on my code?

@curiosport this is cpp files so you need cpp compiler. Then you would open the qiron.pro and compile it all. It would produce some DLLS in the plugin folder. Those should be copied to the plugin folder in QtCreator. Note: the source is for older Qt 4.6 so it might have compile errors u need to fix if using newer Qt.

Thanx bsomervi. Good point. I could go with an even more general signal (like itemClicked) but finding the signal that will more rightly pick only a checkbox checked/unchecked action would be optimal.

Hi, Why not use the parameters of currentItemChanged to get the current item ?

The crash dump only tells me that its a shared memory error, I can't seem to get more detail than that. It seems related to the system clock time (my application lets users change the time), if it has changed that is when the crashing is occuring.

One alternative might be to implement a QAbstractTextDocumentLayout

How can i create my signal for text edit with python3 ? With as many ways i tried, but I did not succeed .. :(

Hi, Are you thinking of something like toPlainText ?
