PyQt5 - 改变按钮的大小

在本文中，我们将了解如何更改按钮的大小。基本上有两种方法可以改变按钮的大小，即使用resize方法和setGeometry方法。
它们之间的主要区别是resize方法只会调整按钮的大小。另一方面setGeometry方法将改变大小并设置按钮的位置。

方法#1：

Syntax : button.setGeometry(left, top, width, height)

Argument : It takes four integer as argument, first two are the position and second two are the size.

Action performed : It sets the position and the size of push button.

代码 ：

# importing libraries
from PyQt5.QtWidgets import * 
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, 600, 400)
  
        # calling method
        self.UiComponents()
  
        # showing all the widgets
        self.show()
  
    # method for widgets
    def UiComponents(self):
  
        # creating a push button
        button = QPushButton("CLICK", self)
  
        # setting geometry of button
        button.setGeometry(200, 150, 100, 40)
  
  
        # adding action to a button
        button.clicked.connect(self.clickme)
  
  
    # action method
    def clickme(self):
  
        # printing pressed
        print("pressed")
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：

方法#2：

Syntax : button.resize(width, height)

Argument : It takes two integer as argument i.e width and height.

Action performed : It sets the size of push button

代码 ：

# importing libraries
from PyQt5.QtWidgets import * 
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, 600, 400)
  
        # calling method
        self.UiComponents()
  
        # showing all the widgets
        self.show()
  
    # method for widgets
    def UiComponents(self):
  
        # creating a push button
        button = QPushButton("CLICK", self)
  
        # setting size of button
        button.resize(150, 50)
  
  
        # adding action to a button
        button.clicked.connect(self.clickme)
  
  
    # action method
    def clickme(self):
  
        # printing pressed
        print("pressed")
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
