Managing the widget layout with layouts


Qt Widgets includes a robust layout system to control the presentation of widgets on the display. In Qt Creator Designer, you can pick from the following layouts:

  • QBoxLayout: This lays out its view children horizontally or vertically

  • QHBoxLayout: This lays out its view children horizontally

  • QVBoxLayout: This lays out its view children vertically

  • QFormLayout: This lays out pairs of widgets (such as labels and textboxes) side by side and then tiles those pairs vertically, giving the appearance of a form

  • QGridLayout: This lays out widgets in a grid

  • QStackedLayout: This shows only a single widget at a time

Using one of these layouts is easy: simply choose the appropriate layout in Qt Creator Designer and drag it to the widget or window you're building. If you're constructing a hierarchy of widgets in the code, you add the widgets to the layout and set the parent widget's layout, like this:

QWidget *window = new QWidget();
QPushButton *button1 = new QPushButton...
