installation

1) installation PyQt5, QtDesigner, PyUIC, opencv other tools

(Before that, we need to complete the installation of python and pip tools)

Open cmd window, enter

pip install pyqt5

The computer will automatically download and install the appropriate version of pyqt5.

Upon completion, then enter

pip install pyqt5-tools

QtDesigner PyUIC automatically complete the installation and the like.

In addition, I am in the process of programming and also used the opencv qimage2ndarray modules, and finally if you want to generate exe executable file you also need to install pyinstaller, its installation commands are:

pip install opencv-python
pip install qimage2ndarray
pip install pyinstaller

At this point, all modules are used in the installation is complete.

2 QtDesigner and PyUIC linked to the external tool library PyCharm

Qtdesigner Python is a design which very useful tool, such that it may be prepared not only pure qt interface code, and may be provided on the basis of the visualization, is very convenient.

After users install PyQt5, the system will be installed by default QtDesigner tool.

Default Default path QtDesigner of: E: \ python \ python \ Lib \ site-packages \ PyQt5 \ designer.exe

*** The person I see is in the Scripts below (at the end of the EXE in my scripts below)

Configuration PyCharm

Open Pycharm, then the following path open Extrernal Tools

File-> Tools-> Extrernal Tools-> click on the "+" sign -> pop-up dialog box with the following configuration

. (1) increase the QT interface design "Qt Designer" - this is the tool Qt interface design

• Program selection path PyQt installation directory of designer.exe
•  Working directory at set their own working path, qtdesigner generated ui files saved in the default path. 'Arguments' not set, to confirm.

(2) increasing the "PyUIC" - this is mainly used to convert the interface into Qt py Code

pyuic qtdesigner for converting the file into the generated .ui python .py files can be identified. Process is provided as shown below, Programs, enter the path and file name where python.exe, Arguments enter:

-m PyQt5.uic.pyuic -o $FileNameWithoutExtension$.py $FileName$

In Working directory enter:

$FileDir$

Py file will thus generated and converted ui files located in the same folder. Click ok to complete the setup.

Method 2 (I do not see pyuic5.bat)

After configuring the installation is complete you can see in our tool oh tools inside
