Hi Josh, thanks for you mail and problem description. A bit hard to guess, since two issues seem to occur at the same time.
You seem to expect that the first checkbox is automatically focused, but it isn't. The missing focus frame can be a consequence or a separate (styling) issue. You can enforce a specific focus chain by calling QWidget::setTabOrder() (tab order and focus chain are the same thing). Depending on whether the dialog subclass has buttons (e.g. Save / Discard), one of them may be its focus proxy. That may also interfere with your focus chain expectations. You may want to raise a topic in https://forum.qt.io Describing the expected behavior and adding a small reproducer will help to identify and solve the issue.

I have created a QStyledItemDelegate subclass. It creates an editor that is a QDialog subclass that has QCheckBoxes in it. The problem is that when the QDialog subclass is shown, the first checkbox isn't drawn with the (blue) focus rectangle around it. If you press an arrow key, the next checkbox will be drawn with it. I call setFocus(Qt::TabFocusReason) on the first checkbox, and then call update() on it, but it won't draw with the focus rectangle. It has the keyboard focus, when I press 'space' it checks the box. But if I press 'tab' the underlying QTableWidget changes cells, unless I first press an arrow key, then the correct checkbox will be drawn with the focus and then the tab key will switch between the checkboxes. I clearly am not understanding something about the focus. Sorry for the complicated email, but in short, what should I do to have the qcheckbox be drawn with the focus rectangle when my qdialog editor is first shown?
