PyQt5 QSpinBox – 获取当前几何图形
在这篇文章中,我们将看到如何获得旋转盒的当前几何图形。几何形状基本上是指旋转盒的位置和大小。为旋转盒设置几何图形可以改变它的大小和位置。我们使用setGeometry方法来设置或改变旋转盒的几何形状。
为了做到这一点,我们使用旋转盒对象的geometry方法。
语法: font_metrics.geometry()
参数: 它不需要参数
返回: 它返回QRect对象
下面是实现方法
# 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, 600, 400)
# calling method
self.UiComponents()
# showing all the widgets
self.show()
# method for widgets
def UiComponents(self):
# creating spin box
self.spin = QSpinBox(self)
# setting geometry to spin box
self.spin.setGeometry(100, 100, 250, 40)
# setting range to the spin box
self.spin.setRange(1, 999999)
# setting prefix to spin
self.spin.setPrefix("PREFIX ")
# setting suffix to spin
self.spin.setSuffix(" SUFFIX")
# creating a label
label = QLabel(self)
# making label multi line
label.setWordWrap(True)
# setting geometry to the label
label.setGeometry(100, 200, 300, 60)
# getting the current geometry
current_geo = self.spin.geometry()
# setting text to the label
label.setText(str(current_geo))
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出:
