以前,我习惯于通过(例如:)
button.clicked.connect(function)
触发按钮和设置。当通过单击鼠标按下按钮时,按钮将改变背景颜色并按预期工作。但是,目前我正在使用触发按钮(例如:),但按钮似乎不受.qss
setStyleSheet()
QPushButton:pressed{background:#EAEAEA;}
QShortcut
QtCore.Qt.Key_Return
qss
我使用的代码:
from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_Form(object):
def setupUi(self, Form):
Form.setObjectName("Form")
Form.resize(400, 300)
Form.setStyleSheet(""
"#Form {\n"
"background-color: rgb(255, 255, 255);\n"
"}\n"
"QPushButton:hover {\n"
"color: white;\n"
"background-color: rgb(255, 85, 127);\n"
"border-radius: 6px;\n"
"font-size:16px;\n"
"}\n"
"\n"
" QPushButton:pressed{\n"
"background:#EAEAEA;\n"
"color: black;\n"
"font-size:16px;\n"
"}")
self.frame = QtWidgets.QFrame(Form)
self.frame.setGeometry(QtCore.QRect(20, 20, 351, 241))
self.frame.setFrameShape(QtWidgets.QFrame.StyledPanel)
self.frame.setFrameShadow(QtWidgets.QFrame.Raised)
self.frame.setObjectName("frame")
self.pushButton = QtWidgets.QPushButton(self.frame)
self.pushButton.setGeometry(QtCore.QRect(130, 100, 93, 28))
self.pushButton.setObjectName("pushButton")
# old (be affected by qss (QPushButton:pressed) when clicking mouse)
# self.pushButton.clicked.connect(self.send_message)
# new (not to be affected by qss (QPushButton:pressed) when using Enter key)
send_message_shortcut = QtWidgets.QShortcut(QtGui.QKeySequence(QtCore.Qt.Key_Return), Form)
send_message_shortcut.activated.connect(self.send_message)
self.retranslateUi(Form)
QtCore.QMetaObject.connectSlotsByName(Form)
def retranslateUi(self, Form):
_translate = QtCore.QCoreApplication.translate
Form.setWindowTitle(_translate("Form", "Form"))
self.pushButton.setText(_translate("Form", "PushButton"))
def send_message(self):
# do something here
print("send message")
if __name__ == "__main__":

app = QtWidgets.QApplication(sys.argv)
Form = QtWidgets.QWidget()
ui = Ui_Form()
ui.setupUi(Form)
Form.show()
sys.exit(app.exec_())
