import sys

from PyQt5.QtGui import QIcon, QFont
from PyQt5.QtWidgets import QApplication, QWidget, QPushButton, QToolTip, QHBoxLayout, QMainWindow

'''
鼠标放到控件上显示提示信息
'''

class TooltipForm(QMainWindow):
    def __init__(self):
        super(TooltipForm, self).__init__()
        self.initUI()
    def initUI(self):
        # 设置定位和左上角坐标
        self.setGeometry(300,300,200,300)
        # 设置窗口标题
        self.setWindowTitle('设置控件提示信息')
        # 设置窗口图标
        self.setWindowIcon(QIcon('../web.ico'))

        QToolTip.setFont(QFont('SansSerif',12))
        self.setToolTip('今天心情好不好?<br><b>当然可以啦!</b>')

        self.button1= QPushButton('一个按钮,试一试鼠标放到我上面')
        self.button1.setToolTip('我只一个按钮哦! 呵呵呵!')
        layout = QHBoxLayout()
        layout.addWidget(self.button1)

        mainFrame = QWidget()
        mainFrame.setLayout(layout)
        self.setCentralWidget(mainFrame)



if __name__ == '__main__':

    app = QApplication(sys.argv)
    # 设置应用图标
    # app.setWindowIcon(QIcon('../web.ico'))
    w = TooltipForm()
    w.show()
    sys.exit(app.exec_())
