Custom widget with new layout?

AndrzejB

How write own complex widget with many pushbuttons etc? I can't find example https://doc.qt.io/archives/3.3/designer-manual-7.html in new Qt.
With this widget I must:

add and remove pushbuttons
if all buttons have smaller size than my container, leave space
else if buttons have bigger size, some buttons are invisible

I must implement new layout?
My goal: I want write breadcrumb like this:

Hi,

You should take a look at libqtxt QxtCrumbView. It implements a breadcrumb widget.

AndrzejB

#include <QxtCrumbView> - can't find file
I must something add to to .pro? I have QT += core gui widgets

You do realise that it's an external library ?

AndrzejB

Aaah.. at first, I thought, that is is a part of Qt, but now I see that is external library
Last commit is 2014-10-07 , it will cooperate with Qt5.12.0 ?

Simply:
QT_STATIC_CONST -> static const
QT_STATIC_CONST_IMPL -> const
