QHBoxLayout小部件对齐仅影响第一个小部件

Question

when I create a QHBoxLayout and I add widgets in it with addWidget and then call myLayout->setAlignment(newWidget, Qt::AlignLeft) , this only snaps the first widget I add. When I add other widgets and set their alignment to left too, they still start off at the center of the layout and then get squeezed in the more widgets I add. How do I make them all stick to the left next to each other?

If I understood it correct, what you want is to have your widgets in a horizontal line but as left as possible?

If so you can add your QHBoxLayot to the general this->getLayout()->addLayout(YourLayout) and then use setContentMargins(); or setStretchFactor(QWidget * widget, int stretch)

Without the code is difficult but ... Another possible problem can be the widgets size. You can fix it using setSizePolicy(...) with the MinimumExpanding setSizePolicy( QSizePolicy::MinimumExpanding, QSizePolicy::Preferred );
