How to install QtDesigner?

Question

I just installed Qt 5.4.1 on Windows 7. And there is no QtDesigner. Also there is no QtDesigner in MaintenanceTool.
How can I install it?

Answer 1

If you are on macOS and use brew you may have installed qt already using brews installer.

In that case you already have QT Designer installed even though it is not mentioned anywhere.

You can find it here: /usr/local/Cellar/qt/<qtversion>/libexec/Designer.app

So to place it in your local apps folder you can create a symlink to it like this:

ln -sf /usr/local/Cellar/qt/5.11.1/libexec/Designer.app ~/Applications/.

Answer 2

It is there. Create a form, click on the .ui file and it opens automatically.

Answer 3

You can install and find QT Designer as follows (Windows environment):

• Install latest QT (I'm using 5.8) from QT main site
• Make sure you include "Qt 5.8 MinGW" component
• QT Designer will be installed in C:\Qt\5.8\mingw53_32\bin\designer.exe
• Note that the executable is named "designer.exe"

UPDATE - there is an easier way to install QT Designer without downloading GB's of data from QT:

• Install the latest version of "pyqt5-tools" using pip install pyqt5-tools --pre

• The "designer.exe" will be installed in ...Lib\site-packages\pyqt5_tools

Answer 4

install designer using apt package manager

sudo apt-get install python-qt4 qt4-designer

run the command designer and it will work for you

if it doesn't try /usr/bin/designer

it worked for me i am using python 3.6 with pyqt-5.16

Answer 5

Install the latest version of "pyqt5-tools" using pip install pyqt5-tools --pre

Then run the command (designer.exe) then you are good

Answer 6

Expanding StonyBoy answer. If you are on macOS, you have installed Qt5 with brew, and you want to access the Qt5 Designer app via command line (like on Linux), you can set a symlink to the actual executable as well, like this:

ln -sf /usr/local/Cellar/qt/5.13.1/libexec/Designer.app/Contents/MacOS/Designer /usr/local/opt/qt/bin/designer

This way, the designer command will be placed in the bin folder, together with the other Qt5 executables (as qmake). Thus, you will be able to launch it simply by typing designer in your shell.

Note: of course you must have the path of the Qt5 bin/ folder added to your PATH environmental variable, for being able to directly call designer in the shell. But brew added it for you when you installed Qt5.
