- Based on Qt 5.12.12 now (tested to build on 5.15)
- QImage constructor with binary data
- More classes, specifically QLibraryInfo for Qt version
- QLayout and derivatives take ownership over widgets added
* #730: providing a new Qt module named QtUiTools for QUiLoader class support.
* Fixed a compile error on Mac
* Added QtUiTools to some more places
* Fixed a linker issue in the QtUiTools Python lib
* On occasion fixed a infinite recursion problem in the debugger
The recursion happened because by mistake I instantiated a
QApplication inside an in-application Python script. This
crashed the debugger due to infinite recursion. This is not
a real use case but to prevent similar issues, a recursion
sentinel was added.
* Removed QCoreApplication#notify from script bindings
Reasoning: "notify" made standalone scripts using QApplication and
QUiLoader virtually impossible.
Problem description:
- When a QApplication object is instantiated, e.g. in Python, the Qt binding
will install reimplementation hooks as the object may be dynamically
extended.
- A notify is virtual this means the *every* "notify" call in the application
is routed through the interpreter.
- For one thing this will slow down the application
- But as "notify" is called a zillion times this has more than this side effect.
- Specifically "notify" is called from within the QWidget constructor to
indicate a new widget. Then, if a QDialog for example is instatiated, it's
base class constructor will call "notify" when the object isn't ready yet.
- This has another severe side effect: as the object isn't ready yet, it gets
registered in the Python space with the wrong class and QDialog is not visible
as such.
To mitigate these problems, the most efficient solution is to disable "notify"
in general. There is hardly any use case in a script environment (in C++,
apart from hacking the only reasonable use case is exception handling, but
this does not apply to scripts). For providing the call functionality of
"notify" you should better use "postEvent" or "sendEvent" anyway.
So farewell QCoreApplication.notify ...
* Fixed python test for QtUiTools module
* Fixed UiTools test on Qt4 - QUiLoader needs an application object

* Fixed#501 (more Qt ownership management) - this commit contains some more changes because I had to regenerate the Qt binding sources.
* Fixed#501 (Qt object ownership transfer) - repairs, added tests
* Updated Jenkinsfile to not publish a PR build
* Update Jenkinsfile - exclude PR's from build
With this change it is possible to bind signals to functions
accepting less arguments. For example:
def triggered():
...
b = pya.QPushButton()
b.clicked(triggered)
b.emit_clicked(True)
wasn't working before since triggered() gets one parameter
(checked) and the call fails. Now, additional parameters are
ignored.
