GUI code

GUI implementation

The GUI is designed with Qt and interpreted by :PyQt5:.

The UI folder is defined as a module loaded in CAtImaPy main code.

The ui object of class UI.Ui_MainWindow control the graphical user interface (GUI). The class definition of UI.Ui_MainWindow is generated automatically in file UI/CAtImaPy_UI.py from the designer file UI/CAtImaPy_UI.ui.

The variables and buttons in the GUI are connected respectively to variables and methods of the mainWin object or its main attributes Imaging or Camera. For most of the variables, the connections are done automatically via mainWin method connectUiVariables(). The remaining few variable connections go through dedicated mainWin methods with format on_<variable name>_valueChanged() or on_<variable name>_stateChanged(), because a value change needs to trigger other changes in GUI values. The buttons are connected via mainWin methods on_<button name>_cliked().

Changing the GUI

  1. Open CAtImaPy_UI.ui in Qtdesigner.

    With Anaconda Prompt run:

    cd <path of CAtImaPy/UI folder>
designer CAtImaPy_UI.ui
  2. Run pyuic5 to translate the ui to python code.

    With Anaconda Prompt run:

    pyuic5 CAtImaPy_UI.ui > CAtImaPy_UI.py
  3. Change last line of CAtImaPy_UI.py to
    from .matplotlibwidget import MatplotlibWidget

    (just add a “.” before “matplotlibwidget”)

  4. Implement feature in code.

    Change MainWindow code and/or other codes to connect and use the new GUI variable or button.
