WidgetActionItem widgets not respecting size hints

[gselzer]

Ideally, if a widget declares a minimum size, the dock widget it is added to would not be able to shrink beyond that size. Confusingly, the dock widget has its minimum size set based on the widget it encloses (although we may want to change that to a maximum operation when multiple tabs have minimum sizes? Not sure), so I'm not sure if I'm misunderstanding what that method does...

Here's an MCVE, adapted from #71:

from PyQt6.QtWidgets import QWidget

from pymmcore_gui import create_mmgui
from pymmcore_gui.actions import WidgetActionInfo


def create_my_widget(parent: QWidget) -> QWidget:
    wdg = QWidget(parent)
    wdg.setMinimumWidth(600)
    wdg.setMinimumHeight(600)
    wdg.setStyleSheet("background-color: lightblue;")
    return wdg

WidgetActionInfo(
    key="mywidget",
    text="My Widget!!!!",
    icon="mdi-light:format-list-bulleted",
    create_widget=create_my_widget,
)
create_mmgui()

yeah, I agree, thanks for opening the issue. That line you found was my quick and dirty workaround for the observation that PyQtAds puts everything into a widget that can very easily be made too narrow (horizontally) and I found myself carefully adjusting widths more than I wanted to. I'm not happy with that line, and I think it's possible that we should look a bit more at the PyQt6Ads code to see what configuration it provides when adding a widget to a dockwidget. 👍
