QtDesinger + Pyqt + pushbutton how to change color on click?

Question

PyQt

There is a button whose Id = button, in QtDesinger it already has its own css.
I want the color to change to black (0, 0, 0) when pressed, but implement it in code.

def function():
        form.fishing_0.setStyleSheet('background: rgb(255,0,0);')

form.fishing_0.clicked.connect(function)

But this way it forgets the whole style of the button and all that remains of the button is text and bg, losing shadows, stroke, etc. What to do?

Answer 1

Either pass the entire style with a changed color (not just the background), or pass colors as arguments when calling the window

# стилизуем через f строки, передавая цвета как аргументы
self.pushButton.setStyleSheet("QPushButton{\n"
                                          "    border-radius: 30px;\n"
                                          f"    border: 2px solid {color_1};\n"
                                          f"    background-color:  {color_2};\n"
                                          "}")

# добавляем аргументы в setupUi
def setupUi(self, MainWindow, color_1, color_2):

# если форма как отдельный модуль
import your_form
self.form = your_form.class_name()

# если в одном файле
self.form = class_name()

# вызываем форму с новыми цветами
def function(self):
    self.form.setupUi(self, "rgb(255,0,0)", "rgb(255,0,0)")
    self.show()

self.form.fishing_0.clicked.connect(function)
