I am trying to find Qt designer app on Mac. I installed anaconda package and conda reports that qt, sip, and pyqt are installed. Still I couldn't find the designer app in any of the folders. My Python app that uses pyqt works perfectly. I'm very new to macs and probably missing something very simple.
I did search folder tree for anything named designer. I found QtDesigner.so (supposed to be executable?) at
/Users/XXXX/anaconda/pkgs/pyqt-4.10.4-py27_0/lib/python2.7/site-packages/PyQt4 but it won't even run saying "cannot execute binary file"
anaconda/bin doesn't have it.
There's a folder anaconda/include/QtDesigner but noting I can run
/anaconda/pkgs/qt-4.8.5-3/bin - no designer. I'm totally confused now.
I can't answer you question definitively as I don't have OSX installed anywhere, but perhaps I can help lead you in the right direction.
1) you are going to want to be looking for Designer, not QT Creator, as Designer is what comes bundled with PyQt4 (PyQt4 is what Anaconda comes packaged with)
2) in linux when you install Anaconda 2.1 to the default location, designer is going to be placed in home/user_name/anaconda/bin/
3) typing 'designer' from a terminal launches designer in linux, so you may not have to bother searching around for it.
Hopefully there is some consistency between linux and osx (windows designer is located in \Anaconda\Lib\site-packages\PyQt4).  
Best of luck.
Where is Qt designer app on Mac + Anaconda?
