Contrary to previous versions that shipped with Qt 4.8.4, IDA 6.9 ships with Qt 5.4.1 and as we announced some time ago, this will force some changes for plugin writers who were using IDAPython + PySide in order to build custom interfaces.
What’s more, in addition to the Qt4 -> Qt5 switch, we have also chosen to drop PySide in favor of PyQt5, as it seems to be more actively developed.
While we were porting some internal plugins & test scripts, we have come across a number of ‘issues’ that are due both to the change in major Qt version, and also to the switch to PyQt5.
Here is a (non-exhaustive) list of such problems that needed to be dealt with.
Use ‘from PyQt5’ instead of ‘from PySide’
from PySide import QtCore, QtGui
from PyQt5 import QtCore, QtGui, QtWidgets
(notice the added ‘QtWidgets’. Keep reading.)
Most widgets are now in QtWidgets, not QtGui anymore (Qt5 architecture change)
from PySide import QtGui edit = QtGui.QTextEdit()
from PyQt5 import QtWidgets edit = QtWidgets.QTextEdit()
Converting TForm instances must be done to PyQt
from PySide import QtGui, QtCore form = idaapi.find_tform("Output window") w = idaapi.PluginForm.FormToPySideWidget(form)
from PyQt5 import QtGui, QtCore, QtWidgets form = idaapi.find_tform("Output window") w = idaapi.PluginForm.FormToPyQtWidget(form)
Public QEvent types are in QtCore.QEvent namespace
Using QObject.connect() to connect signal with slot doesn’t work anymore. Use alternative approach.
obj.connect(query_action, QtCore.SIGNAL("triggered()"), self.ui.queryGraph)
Misc. required changes (reported by our users)
- QHeaderView.setResizeMode => QHeaderView.setSectionResizeMode
- QtCore.Qt.ItemFlag enum was moved to be accessed directly on QtCore.Qt
- QColorDialog.setCustomColor now takes a QColor instead of an RGB int as the second argument.
As I said above, this is a non-exhaustive list of issues we encountered. Should you encounter other issues, please let us know about them, so we can update & improve this page to help the community!
