Fundamentals of Qt - Objects in Qt, part 1/3 - Qt objects and UI elements - First steps

Great video. What about creating one like “how to think in Qt?”. I mean, sync and async programming model.

Great start, but not clear. The layouts are not given a parent. Why? You say all QWidget’s apart from the top level need a parent for memory management yet this is not so in your example and you give no explanation. Does your example code leak memory then? Or is it tidied up some other way. Perhaps children are reference counted? Important fundamental questions not covered :-(

QBoxLayout::addLayout(QLayout * layout, int stretch = 0) and QWidget::setLayout (QLayout * layout) will take care of parenting.

Take a look at this thread [qt-project.org] as well as the documentation [qt-project.org]

There is no accessible content available. Has this and other videos been removed?
