Qt designer via homebrew
问题 I installed Qt5 via homebrew, but I didn't find the designer. I also installed qtcreator ( Caskroom/cask/qt-creator ) but the designer icon is grayed out: Any ideas where I can find the designer? p.s. Does this means that designer is going to retire? 回答1: If you double-click on a .ui-File (within Creator), the Designer will become active. Or you need to add a Qt-Designer-Form with the wizard if you have no ui file yet. 回答2: otherise you can open Qt Designer alone (not inside Qt Creator) by
