Qt removing stretches from a QHBoxLayout

Question

after adding a stretch with QBoxLayout::addStretch, can I then somehow remove it? I want to keep adding a stretch at the end of the layout after every widget I add, so I have to remove the old stretch, add the new widget and add a new stretch after that.

Answer 1

Instead of removing and adding the stretch at the end, you could start with a layout containing only the stretch.

Then, instead of adding the new widget, you insert it at position layout->count()-1. The stretch will shift one position to the right.

So:

QHBoxLayout* layout = new QHBoxLayout();
layout->addStretch();
setLayout(layout);

...

layout->insertWidget(layout->count()-1, yourWidget);
