There is a bash command that comes with installing PyQT Creator called designer that will run a tool called Qt Designer, found under the Qt Creator package. It helps you create GUIs - pretty cool stuff.

There is a problem though... whenever I run designer, I get this error:

designer: could not exec '/usr/lib/x86_64-linux-gnu/qt4/bin/designer': No such file or directory

And that's great - I don't want it to execute /usr/lib/x86_64-linux-gnu/qt4/bin/designer, I want it to execute /usr/lib/x86_64-linux-gnu/qt5/bin/designer, the difference being between "qt4" (first path) and "qt5" (second path). That's where designer is.

I looked around and found this command type -a (command) and it would tell you where the command definition is "located", if I understand correctly. So I looked it up and got:

$ type -a designer
designer is /usr/bin/designer

But I can't edit that file... it's a bunch of gibberish (side question, what does it mean when a file has no file extension? What does that make it?)

So, my question is, how can I get the command designer to execute /usr/lib/x86_64-linux-gnu/qt5/bin/designer?

Edit: which designer also returns /usr/bin/designer,

also: $ file /usr/bin/designer /usr/bin/designer: symbolic link to qtchooser'

So I also took a look at qtchooser... seems like its a command (not entirely sure what it does).

Here is some output:

file /usr/bin/qtchooser 
/usr/bin/qtchooser: ELF 64-bit LSB  executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.24, BuildID[sha1]=96215e9441b8361f0cc57b37db70fc50752cb05a, stripped

Thanks to @dessert for helping me out.

I ran sudo apt-get install qt5-default and everything worked fine.

The answer was "inspired" from the answer here, which didn't work for me, but might work for you if you are having the same problem and my solution didnt work.

While this does not directly answer my question... it solves my problem, so yay
