Hiho, I kind of have a very specific case to deal with (Qt5, Widgets, QtDesigner in QtCreator):
I have a custom widget (A) in the QtDesigner in QtCreator that I can add, modify, and remove there, storing works as well. It has its own QDesignerTaskMenuExtension, that allows to open an extra dialog, where a bunch of Q_PROPERTY entries are handled (works as well), and stored after dialog close. That widget shall now get an option to dynamically create/remove helper widgets (B) that shall be stored as children of A. These B widgets are custom widgets too, but are not part of the QtDesigner widget box, although they shall be stored in the ui file too (seems to be possible: https://doc.qt.io/qt-5/designer-creating-custom-widgets.html#notes-on-the-domxml-function). In my dialog of A, where I modify the “normal” Q_PROPERTYs I now create these Bs, and want to add them as children of A in the ui file. Although added as actual children of A (simply calling setParent, in gdb I see that they are registered correctly), I fail to store them in the ui file. I get my formwindow and cursor to set/reset the properties, but that information never reaches the ui file. I sincerely hope and appreciate that anyone here could give me some hints about my topic, Many thanks in advance, Cheers, Jakob P.S.: as far as I understand the documentation, A is not a container in QtDesigner sense (https://doc.qt.io/qt-5/qdesignercustomwidgetinterface.html#isContainer), since that one is used for being able to use layouts and such. Additionally it is not a custom container like https://doc.qt.io/qt-5/qdesignercontainerextension.html#addWidget, since these helper widgets are not pages, but represent dynamical sets of extra properties, that shall be added/removed as needed during design time. They have no paint events, but have other jobs to do. FN 181686 k. HG Wien, UID-Nr.
