PySide6 – Как сделать окно прозрачным, но кликабельным? ⇐ Python

[Anonymous]

Я создаю инструмент для создания снимков экрана с помощью PySide6 и хочу создать невидимое безрамочное окно, чтобы пользователь мог перетаскивать и захватывать его. Но каждый известный мне метод позволяет щелкнуть мышью за окном, а не в окне.
Есть ли способ сделать окно прозрачным и получает ввод мыши? (Я успешно создал инструмент для обрезки с помощью Tkinter, но не хочу использовать tkinter)
Это мой код, использующий PySide6 (работает на Mac):
from PySide6 import QtWidgets, QtCore, QtGui
from PySide6.QtWidgets import QApplication, QWidget
from PySide6.QtGui import QScreen, QPixmap
import sys

using_debug_mode = None

class DraggingPanel(QWidget):
def __init__(self, callback=None, cancel_callback=None):
super().__init__()
self.callback = callback
self.cancel_callback = cancel_callback
self.start_x = None
self.start_y = None
self.rect:QtCore.QRect = None

window_tools.set_frameless(self)

### just look at here is enough ###

# method 1: cannot click on the window
'''
widget.setAttribute(QtCore.Qt.WA_TranslucentBackground)
'''

# method 2: cannot click on the window
'''
self.setStyleSheet('background-color: #00000000;')
'''

# method 3: when opacity 0 and h > 0:
def do_capture():
screen_cap = QScreen.grabWindow(QApplication.primaryScreen(), 0, 0,
screen.width(),
screen.height())
to_img_scale_x = lambda val: round(val * screen_cap.width()/screen.width())
to_img_scale_y = lambda val: round(val * screen_cap.height()/screen.height())
screen_cap = screen_cap.copy(to_img_scale_x(x1),
to_img_scale_y(y1),
to_img_scale_x(w),
to_img_scale_y(h)) if True else screen_cap
if using_debug_mode: print("Screenshot taken!")
QtCore.QTimer.singleShot(1, lambda: self.callback(screen_cap) and self.deleteLater())
QtCore.QTimer.singleShot(1, do_capture)
else:
if using_debug_mode: print("Screenshot canceled!")
QtCore.QTimer.singleShot(1, lambda: self.cancel_callback() and self.deleteLater())

# Get current flags and remove the FramelessWindowHint flag
widget.setWindowFlag(flag, on=on)

"the mouse can click behind the window."
window_tools.set_flag(widget, QtCore.Qt.FramelessWindowHint, on=frameless)
widget.setAttribute(QtCore.Qt.WA_TranslucentBackground, on=transparent_no_enitity)
def set_bg_to_almost_transparent(widget):
"Opacity: 1/255, Clickable\n\n`widget.setStyleSheet('background-color: #01000000;')`"
widget.setStyleSheet('background-color: #01000000;')
@staticmethod

@staticmethod
def create_window(title="", borderless=False, always_on_top=False, width=300, height=300):
# Create a new QWidget (or QMainWindow)
new_window = QWidget()
new_window.setWindowTitle(title)

# Set window flags based on parameters
new_window.setWindowFlag(QtCore.Qt.FramelessWindowHint, borderless)
new_window.setWindowFlag(QtCore.Qt.WindowStaysOnTopHint, always_on_top)

# Set the size of the window
new_window.resize(width, height)

return new_window
