Description Miro Hrončok 2018-07-02 20:04:25 UTC
This reproducer:

import sys
from PyQt5.QtWidgets import QApplication
from PyQt5.Qsci import QsciScintilla

class SimplePythonEditor(QsciScintilla):

    def __init__(self, parent=None):
        self.setMarginSensitivity(1, True)
        self.markerDefine(QsciScintilla.RightArrow, self.ARROW_MARKER_NUM)

    def on_margin_clicked(self, nmargin, nline, modifiers):
        if self.markersAtLine(nline) != 0:
            self.markerDelete(nline, self.ARROW_MARKER_NUM)
            self.markerAdd(nline, self.ARROW_MARKER_NUM)

if __name__ == "__main__":
    app = QApplication(sys.argv)
    editor = SimplePythonEditor()

Version-Release number of selected component (if applicable):

How reproducible: in mock

Steps to Reproduce:
1. xvfb-run python3 # code form above

Actual results:
QObject::connect: No such signal SimplePythonEditor::marginClicked(int,int,KeyboardModifiers)
TypeError: connect() failed between (int,int,Qt::KeyboardModifiers) and unislot()

Expected results:
this works on Fedora 28. if you uncomment the commented lines at the end, you can actually click the margin.

Additional info:
This makes mu FTBFS. Reproduced on Python 3.6 and 3.7 as well.

I'm seeing something similar with calibre (python2):

The main screen never shows up, it just exits. :( Not sure how to debug this...

Comment 6 Miro Hrončok 2018-07-17 12:43:02 UTC
I cannot rebuild mu due to this. Setting blocks: PYTHON37, as mu still depens on python 3.6.

Comment 7 Miro Hrončok 2018-07-17 12:46:12 UTC
Actually not vene that, it's failing with:

    from PyQt5.Qsci import QsciScintilla, QsciLexerPython, QsciAPIs
E   ValueError: PyCapsule_GetPointer called with incorrect name

Comment 9 Miro Hrončok 2018-07-17 13:02:39 UTC
Filled bz1601917. leaving this open as it is currently unknown whether this got fixed or not.

Comment 10 Jan Kurik 2018-08-14 09:56:06 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 29 development cycle.
Changing version to '29'.

Comment 11 Rex Dieter 2018-08-14 20:01:06 UTC
I believe this is fixed (at least partially), mu rawhide scratch build succeeded for me,
