c++ - icon for QT app -

-

i'm using qtcreator build application on mac. @ time application icon default 1 set qt creator.

i set 1 custom specific app.

what have in in .qrc file, have added 

<rcc>     <qresource prefix="/">         <file>main.qml</file>         <file>images/logo.icns</file>     </qresource> </rcc>

i have made try on main.cpp adding 

qicon icon(":images/logo.icns"); qapplication app(argc, argv); app.setwindowicon(icon);

it doesn't work... have tried in class in define how window of app done

qicon icon(":images/logo.icns");  qmainwindow *window = new qmainwindow();  window->setwindowtitle(qstring::fromutf8("puls")); window->resize(600, 600); qwidget *centralwidget = new qwidget(window); centralwidget->setwindowicon(icon);

it's not working.

the icon's path may incorrect.

try change

qicon icon(":images/logo.icns");

to

qicon icon(":/images/logo.icns");

cause of .qrc file define prefix:

<qresource prefix="/">
