在PyQt5中,你可以使用`QObject.connect()`函数将键盘快捷键绑定到QPushButton上,以便当用户按下特定的组合键时触发按钮的功能。以下是一个简单的例子:
```python
from PyQt5.QtWidgets import QApplication, QMainWindow, QPushButton
from PyQt5.QtGui import QKeySequence
class MainWindow(QMainWindow):
def __init__(self):
super(MainWindow, self).__init__()
self.button = QPushButton('按Ctrl + A')
self.button.setGeometry(50, 50, 100, 30)
# 绑定键盘快捷键 Ctrl + A
self.button.setShortcut(QKeySequence('Ctrl+A'))
# 当快捷键被按下时触发的信号槽连接
self.button.clicked.connect(self.button_clicked)
def button_clicked(self):
print("Button clicked using the shortcut!")
if __name__ == '__main__':
app = QApplication([])
main_window = MainWindow()
main_window.show()
app.exec_()
```
在这个例子中,当你在窗口中按下Ctrl + A键时,就会打印出"Button clicked using the shortcut!"。注意,`QShortcut`是用于处理键盘快捷键的工具,而`clicked.connect()`则是用来链接按钮的点击事件到某个槽函数。
