Have you considered using a QListView instead of a QListWidget?  I believe that 
allows you to save your robot objects, etc. in a plain data object, and then 
display them in the same list display as QListWidget.  I do believe QListWidget 
is much easier, though and wonder if the model/view architecture is worth the 
increased complexity for your case.  But in any case, I think that is how the 
folks at Qt provided for what you are trying to do.

Re: [PySide] Problem with garbage collection

[David Ching]

>from: "henry.w...@yahoo.com" 

Henry> it seems like the clear method of the listwidget was the problem.?
Here is what I tried.
[...]
 The objects are ~just~ created from XML.  When I display those items using
the ListWidget .addItem() method they display correctly.? But only the first
time!? If I clear the list and display the same objects in the same list a
second time then I get the error. So it seems that the addItem method "takes
control" of the object in the Python list and the clear() method destroys
the internal object - even though I can print the objects in the Python list
so they seem to still exist. They are like zombies without a C++ soul :) 
[...]
Lastly, I eliminated the trouble-causing clear() method completely and now
"remove" the list items manually like this:
for N in range( ListWidget.count(), -1, -1): 
Whatever = ListWidget.takeItem(N) 
I don't feel very professional doing it this way, but it seems to be
working.

The C++ code for QListWidget::clear() is as follows.  

 1: // NOTE:  QListWidget::clear() calls QListModel::clear()
 2: void QListModel::clear()
 3: {
 4: beginResetModel();
 5: for (int i = 0; i < items.count(); ++i) {
 6: if (items.at(i)) {
 7: items.at(i)->d->theid = -1;
 8: items.at(i)->view = nullptr;
 9: delete items.at(i); 
10: }
11: }
12: items.clear();
13: endResetModel();
14: }


So yes, on line 9, the QListWidgetItem C++ object is deleted (so it's
"soul") is indeed destroyed!  This is printed in red at
https://doc.qt.io/qt-6/qlistwidget.html#items:  "Warning: All items will be
permanently deleted."

Why do you need to access the QListWidgetItem after you clear it from the
list?  Perhaps you should create new QListWidgetItem's and call
QListWidget.addItem() for those new instances instead.  

Or just use QListWidget.takeItem() as you have done.  Nothing wrong with
that.  

I have also found QListWidgetItem.setHidden() to be great as it lets me keep
the item in the list but the user has no knowledge.

Good luck,
David

Re: [PySide] LGPL licensing obligations

[David Ching]

For now, I just posted a written offer.  The app is not expected to have 
widespread interest, I would be surprised if anyone bothered to ask.  If they 
do, I will get the needed info at the time.  I would be interested in 
commercially licensing Qt under the startup plan (it is $500/year), but it is 
vague whether this is an option any more, and when it was, they claimed to 
audit tax documents to check the revenue is less than a certain amount, and I 
don’t have a separate entity set up for that.

Meanwhile, I could not find the source to the pyside6 wheel... does anyone know 
if this is available?  If so, I could redistribute that.  Or maybe I can just 
zip up what is installed with “pip install PySide6” and call it a day.

The Qt for Python licenses for what it uses are at 
https://doc.qt.io/qtforpython/licenses.html but I don’t use any of the affected 
functionality, so I don’t think I have to include them.  I haven't found the 
webpage listing the C++ Qt licenses of what it uses yet.

Does anyone know of any existing PySide6 LGPL projects where these deployment 
issues have been resolved?  The process of LGPL licensing of Qt for Python 
might itself by open sourced!  

Thanks,
David

[PySide] LGPL licensing obligations

[David Ching]

Hello, 

I am preparing to deploy an application which has a dependency on Qt for
Python, which I am licensing under the LGPL license.  I have not found any
specific documentation on how to do this.  In the Qt Licensing FAQ at
https://www.qt.io/faq/tag/qt-open-source-licensing?hsLang=en, it says:

"You will need to deliver the complete source code of Qt libraries you used,
including all modifications you did or applied, to your users/customers.
Alternatively, you need to provide a written offer with instructions on how
to get the source code. Please also note that this has to be under your
control, so a link to the source code provided by the Qt Project or Qt
Company is not sufficient."

How would I distribute the source code to "Qt for Python"?  Is that even
available?  I just install the pyside6 wheel, I've never dealt with any
source code for the Python Qt wrappers.  

In addition to whatever source code I need for "Qt for Python", do I also
need to deliver the Qt C++ code available at
https://www.qt.io/offline-installers?  I am using Nuitka to bundle and
distribute the app, and modules like QT6GUI.DLL are included in the bundle.
Do I need to distribute the C++ source to QtGui?

Thank you for any enlightenment!

PySide2 shows small text not adjusted for high-dpi monitor.  It did not seem

PySide6 was entirely correct. 

See below

 

On Windows 10, Pyside 5.15.2.1:  

Selection doesn't become red.

No indented tick.

 



 

 

 

On Windows 10, Pyside 6.3.2 (change "import PySide2" to "import PySide6")

Selection correctly is red.

No indented tick (also correct).

Great! I am glad to help, I wish continued traffic on the mailing list as I

Re: [PySide] editing selected cells in QTabelWidget

[David Ching]

Even if you got the right click to actually set focus to the combo box on
one item, I am not sure the user would find that intuitive.  Right-clicking
usually brings up a context menu.  On deeper thought, it seems to be a
conflict of using the persistent editor with a selection of multiple items.
It's not standard.  I would instead propose:

Insert a first column of checkmark controls.  Selecting an item checks this
checkbox.  In the end, multiple selections will have checkmarks.  Then you
can single click a combo box as normal, change the selection, and have it
apply to all the items with checkmarks.  Would that work for you?

Thanks,
David

reset.

In general, double clicking on a multiple selection doesn't work since as
you note, the first click (of the double click) selects the single item that
was clicked and de-selects the other items.  To edit multiple selected items
(my app runs on Windows) I select them and then start editing by pressing F2
(which Excel uses similarly) or a toolbar button, or right-clicking one of
the selected items which opens a context menu with an Edit item.

I had a similar task:

MyTableWidget::MyTableWidget(QWidget *parent) : QTableWidget(parent)
{
m_delegate = new MyTableItemDelegate();  // MyTableItemDelegate is
derived from QStyledItemDelegate
setItemDelegate(m_delegate);
}

MyTableItemDelegate overrides createEditor(), setEditorData(),
setModelData(), updateEditorGeometry().

Apologies, this code is in C++.  It has been years since I developed this
code, so don't know more details off the top of my head.

Hope this helps,
David

Hi Paolo,

I again tried your original code, and this time got an error:

c:\Src\paolo_orig>python pyDBManager.py
Traceback (most recent call last):
  File "c:\Src\paolo_orig\pyDBManager.py", line 166, in

setupUi
self.tab_widget.setCurrentIndex(3)
AttributeError: 'PySide6.QtWidgets.QSpacerItem' object has no attribute
'hasHeightForWidth'


I had rebuilt your code by editing your batch file to fix directories on my
system and ran it.  This runs uic and rcc.  I diffed the results with yours.
Earlier I had missed differences in the generated
"UI\DBManagerMainWindowBad.py" in line 246:

Yours:  self.tab_widget.setCurrentIndex(3)
Mine:   self.tab_widget.setCurrentIndex(0)

I don't know why the generated file was different; perhaps because I am
using 6.2 tool and you are using 6.3.  But, when I changed mine to be like
yours, I got the same error.  

Having reproduced your issue, I tried moving the snake_case enabling before
and after the import of the generated code, and it made no difference, i.e.
there was an error with both:

from Ui.DBManagerMainWindowBad import Ui_DBManagerMainWindow
from __feature__ import snake_case, true_property

and

from __feature__ import snake_case, true_property
from Ui.DBManagerMainWindowBad import Ui_DBManagerMainWindow


Since that failed, I disabled snake_case --- I verify with you that it fixes
it!

I commented out
  #from __feature__ import snake_case, true_property

And to avoid Atttribute errors at runtime, changed the necessary calls to
methods of the "self.ui.xxx" widgets to use camelCase e.g.
#self.ui.status_bar.add_permanent_widget(self.status_log)
self.ui.status_bar.addPermanentWidget(self.status_log)

Then it worked --- there does seem to be an error in generated code if snake
case is enabled.  

Thanks,
David

Paolo, I don't know, I went onto a different machine with Python 3.10
installed and did a "pip install pyside6-essentials", got the same thing you
did.  But unlike you, "python.exe pyDBManager.py" with these lines worked
fine:

[pyDBManager.py] 
#from Ui.DBManagerMainWindowGood import Ui_DBManagerMainWindow
from Ui.DBManagerMainWindowBad import Ui_DBManagerMainWindow

from __feature__ import snake_case, true_property 


Are you sure VS Code is running it from the correct environment?  If you can
comment out enough of the non-working version for it to stay running, you
could run SysInternals Process Explorer and set it's lower pane to view the
DLL's running in the "python.exe" process -- then you can make sure the Qt
DLL's are correct.

Thanks,
David

Paolo, FWIW, I did a "pip install pyside6" and not the "pyside6-essentials".
Maybe that makes a difference.  Like I said, your code works fine here,
including with the "snake case" enabled.

Thanks,
David

Paolo, I would re-install Pyside.  Or even your entire Python distribution.
Something seems wrong with your installation because your "bad" file works
perfectly fine on my system.  In particular, all these missing attributes in
the layout and spacer classes seem to indicate a mismatch of some binaries
in your installation.  

It does seem the .ui files were processed by the correct uic utility, given
the comments in the generated .py files from that.  But the runtime Qt DLL's
just aren't supporting the required attributes somehow.

Hope this helps,
David

Re: [PySide] QtDesigner ???

[David Ching]

Hi Paolo,

I could not reproduce.   Either:

[pyDBManager.py]
#from Ui.DBManagerMainWindowGood import Ui_DBManagerMainWindow
from Ui.DBManagerMainWindowBad import Ui_DBManagerMainWindow

Or:
[pyDBManager.py]
from Ui.DBManagerMainWindowGood import Ui_DBManagerMainWindow
#from Ui.DBManagerMainWindowBad import Ui_DBManagerMainWindow

Ran without error.  The first added the Label and LineEdit as expected.

I ran your batch file after modifying it to work on my system (removed
hard-coded paths, etc.)  So I re-ran pyside6-uic and pyside6-rcc and ensured
the generated files were the same as yours.  They were, except for the
tooling version in the comments.  Mine is slightly older: 

My system:
* Windows 10
* Python 3.9.6 (from https://python.org)
* PySide6 6.2.3

In short, the (essentially) exact .py code works flawlessly here.

Let me know if I can help more,
David

[PySide] Nuitka issue on macOS

[David Ching]

Hello, I am trying to use Nuitka to compile and distribute my Qt for Python
app.  https://doc.qt.io/qtforpython/deployment-nuitka.html cites a known
problem:  "Nuitka currently has a problem with the macOS bundle files on
current macOS versions. That has the effect that -standalone and -onefile
create a crashing application. Older versions which don't have the recent
macOS API changes from 2020 will work. We are currently trying to fix that
problem."  

I am using MacOS Monterey 12.1, Python 3.10 installed from python.org.  I am
not sure if the above means if I run Nuitka on an earlier MacOS version that
it will successfully build? 

I compiled the app using this command-line:

  python3 -m nuitka --follow-imports -standalone --enable-plugin=pyside6
mainscratch.py

Running the resulting app crashes my app referencing
QtQml.framework/Versions/A/QtQml:

Traceback (most recent call last):
  File "/Users/Ken/Desktop/QtScratch/mainscratch.dist/mainscratch.py", line
5, in 
ImportError:

'/Library/Frameworks/QtQml.framework/Versions/A/QtQml' (no such file),
'/System/Library/Frameworks/QtQml.framework/Versions/A/QtQml' (no such file)

I do not use QML in my app, so could I workaround this?  How would I specify
not to include the QML module?  Or would there then be the same problem with
the remaining modules? 

Any fixes or workarounds would be helpful, as I think this problem has been
around for awhile and there is no sign of progress.  

Thanks,
David
