PyQt -窗口的位置

Question

def location_on_the_screen(self):
    fg = self.frameGeometry()
    sbrp = QDesktopWidget().availableGeometry().bottomRight()
    fg.moveBottomRight(sbrp)
    self.move(fg.topLeft())

我不能把窗口放在屏幕的右下角。frameGeometry()没有正常工作。帮帮我，我能做什么?

Answer 1

这是windows的一个可能的解决方案:

import sys
from PyQt5.QtWidgets import QApplication, QWidget, QDesktopWidget

class MyWidget(QWidget):
    def __init__(self):
        super().__init__()
        self.setFixedSize(400, 300)
    def location_on_the_screen(self):
        ag = QDesktopWidget().availableGeometry()
        sg = QDesktopWidget().screenGeometry()
        widget = self.geometry()
        x = ag.width() - widget.width()
        y = 2 * ag.height() - sg.height() - widget.height()
        self.move(x, y)
if __name__ == '__main__':
    app = QApplication(sys.argv)
    widget = MyWidget()
    widget.location_on_the_screen()
    widget.show()
    app.exec_()

Answer 2

from PyQt5.QtWidgets import QMainWindow, QLabel
from PyQt5.QtWidgets import QGridLayout, QWidget, QDesktopWidget
#------------------------------   
def center_window():
   qtRectangle = self.frameGeometry()
   centerPoint = QDesktopWidget().availableGeometry().center()
   qtRectangle.moveCenter(centerPoint)
   self.move(qtRectangle.topLeft())
   #---------------------------------
if __name__ == '__main__':
    app = QApplication(sys.argv)
    widget = MyWidget()
    widget.window_center():
    widget.show()
    app.exec_()

我假设您的'窗口'是QWidget的子类。如果是这样，以下内容应该符合您的需求:

import sys
from PyQt5.QtWidgets import QApplication, QWidget, QDesktopWidget

class MyWidget(QWidget):
    def __init__(self):
        super().__init__()
        self.setFixedSize(400, 300)
    def location_on_the_screen(self):    
        screen = QDesktopWidget().screenGeometry()
        widget = self.geometry()
        x = screen.width() - widget.width()
        y = screen.height() - widget.height()
        self.move(x, y)

if __name__ == '__main__':
    app = QApplication(sys.argv)
    widget = MyWidget()
    widget.location_on_the_screen()
    widget.show()
    app.exec_()
