collagraph QScrollArea

[jamesdbrock]

I want a QScrollArea which contains a QBoxLayout.

        return cg.h(
            "QScrollArea",
            {
                "vertical-scroll-bar-policy": Qt.ScrollBarAlwaysOn,
            },
            cg.h(
                "Widget",
                {
                    "layout": {
                        "type": "Box",
                        "direction": "TopToBottom",
                        "alignment": Qt.AlignTop,
                    },
                },

I'm having the same problem as this guy.

The top voted answer to use QScrollArea::setWidget agrees with this blog post. https://www.pythonguis.com/tutorials/pyside-qscrollarea/

But how can I set the widget property?

        return cg.h(
            "QScrollArea",
            {
                "vertical-scroll-bar-policy": Qt.ScrollBarAlwaysOn,
                "widget": cg.h(
                    "Widget",
                    {

I cannot set the widget property this way because TypeError: 'PySide6.QtWidgets.QScrollArea.setWidget' called with wrong argument types: PySide6.QtWidgets.QScrollArea.setWidget(VNode)

This would require some extra code, like here: https://github.com/fork-tongue/collagraph/blob/master/collagraph/renderers/pyside/objects/qobject.py to implement how to add/set a widget to a scroll area.

Actually, this https://github.com/fork-tongue/collagraph/blob/master/collagraph/renderers/pyside/objects/itemmodel.py would be a better example. After the weekend I can help out with this. Should be fairly straightforward to implement.

Is there a way to do this without making changes to

collagraph/collagraph/renderers/pyside_renderer.py

Line 47 in ba447e1

INSERT_MAPPING = sorted_on_class_hierarchy(

?

No, that is exactly where the new methods should be registered. We could maybe standardize a bit on the interface and then load all methods from the modules within the objects folder, such that it would pick up new methods from new modules automatically.

Yeah it would be nice if new custom QWidget registrations could be done in user code. re-wx has a way to register type-level dispatch of custom widgets from user code with decorators. https://github.com/chriskiehl/re-wx/blob/main/rewx/dispatch.py

In user code it looks like this. chriskiehl/re-wx#21
