[PySide] QtDesigner ???

[Cristián Maureira-Fredes]

Hey,

(remember to reply to the list, so other folks can read the discussion,
I'm adding the ML on CC to jump back to the topic)

Maybe you are hitting https://bugreports.qt.io/browse/PYSIDE-1561

Can you share more information regarding how you are using the generated
ui file?

You should be able to have 1 file with the option,
and another one without.

Let's say your generated file is this one:

---
from PySide6.QtWidgets import QLabel

class MyLabel(QLabel):
     def __init__(self, parent=None):
         super().__init__(parent)
         # Using camelCase
         self.setText("Hello")

     def connectNotify(self):
         pass
---

Which is not using snake_case,
then you can import it and use it:


---
import sys
from PySide6.QtWidgets import QApplication, QWidget, QHBoxLayout

from a import MyLabel

from __feature__ import snake_case

class MyWidget(QWidget):
     def __init__(self, parent=None):
         super().__init__(parent)

         self.label = MyLabel()
         # overriding the value, with snake_case
         self.label.set_text("World")

         layout = QHBoxLayout()
         layout.add_widget(self.label)
         self.set_layout(layout)

if __name__ == "__main__":

     app = QApplication()
     w = MyWidget()
     w.show()
     sys.exit(app.exec())
---

Executing that will have 'World' on the Widget.

When you use the __feature__ import shouldn't matter.

I hope it helps!

Cheers
