PyQt5 QDockWidget – 获取帧大小
在本文中,我们将了解如何获取 QDockWidget 的帧大小。 QDockWidget 提供了停靠小部件的概念,也称为工具面板或实用程序窗口。停靠窗口是放置在 QMainWindow(原始窗口)中中央小部件周围的停靠小部件区域中的辅助窗口。此属性保存小部件的大小,包括任何窗口框架。
默认情况下,此属性包含一个取决于用户平台和屏幕几何形状的值。
In order to do this we will use frameSize
method with the dock widget object.
Syntax : dock.frameSize()
Argument : It takes no argument
Return : It returns QSize object
下面是实现
Python3
# importing libraries
from PyQt5.QtWidgets import *
from PyQt5 import QtCore, QtGui
from PyQt5.QtGui import *
from PyQt5.QtCore import *
import sys
class Window(QMainWindow):
def __init__(self):
super().__init__()
# setting title
self.setWindowTitle("Python ")
# setting geometry
self.setGeometry(100, 100, 500, 400)
# calling method
self.UiComponents()
# showing all the widgets
self.show()
# method for components
def UiComponents(self):
# creating dock widget
dock = QDockWidget(self)
# setting title to the dock widget
dock.setWindowTitle("GfG Dock")
# push button
push = QPushButton("Press", self)
# setting widget to the dock
dock.setWidget(push)
# creating a label
label = QLabel("GeeksforGeeks", self)
# setting geometry to the label
label.setGeometry(100, 200, 300, 80)
# making label multi line
label.setWordWrap(True)
# setting geometry tot he dock widget
dock.setGeometry(100, 0, 200, 30)
# getting frame size of dock
value = dock.frameSize()
# setting text to the label
label.setText("Frame Size : " + str(value))
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出 :
