How do I add a QSpacerItem to a toolbar?

Since a QSpacerItem does not inherit QWidget, I can't use addWidget(). So how do I add a spacer to a toolbar?

You can use QToolBar's addSeparator() or insertSeparator().

All addSeperator() did was add this little vertical line. I was hoping to add more space and have the ability to customize the scaling and such.

Hi Di_Zou,
even i'm also trying same thing, to add spaceritem in toolbar. If u've done this, plz tell me how to do.
Thank u.

Add an empty QLabel. The only downside of this I found so far is that you wont be able to move the window around on macos when clicking on that empty space made by the label.

Add a QWidget instead of a QSpacerItem, set the size policy on the spacer and add the widget to the toolbar.

Code:

---

QWidget* spacer = new QWidget();
spacer->setSizePolicy(QSizePolicy::Expanding, QSizePolicy::Expanding);
// toolBar is a pointer to an existing toolbar
toolBar->addWidget(spacer);
