PyQt是Python语言环境的GUI编程解决方案之一,另外还有PyGTK、wxPython等也较为常用。PyQt作为Qt语言的Python扩展,可以用来方便快速的开发界面应用。
QMessageBox消息弹窗类在QtWidgets模块中定义,使用时需要from qtpy import QtWidgets
。
具体使用示例如下:
from qtpy import QtCore
from qtpy import QtWidgets
from qtpy import QtGui
# TracelessLe注:代码示例,不可直接执行
class MainWindow(QtWidgets.QMainWindow):
def __init__(self):
pass
def show_msg(self):
msg_info= self.tr('input is error!')
self.run_messagebox(msg_info, msg_level='Warning')
def run_messagebox(self, msg_in, msg_level='Warning'):
mb = QtWidgets.QMessageBox
msg = self.tr(
msg_in
)
if msg_level=='Warning':
answer = mb.warning(self, self.tr('Warning'), msg, mb.Yes)
elif msg_level=='Info':
answer = mb.information(self, self.tr("Info"), msg, mb.Yes)
else:
pass # 还有其他支持的方法
return
除了上述示例中的Warning
和Info
方法外,还有其他支持的方法:
@staticmethod
def about(parent: QWidget, caption: str, text: str) -> None: ...
@staticmethod
def critical(parent: QWidget, title: str, text: str, buttons: typing.Union['QMessageBox.StandardButtons', 'QMessageBox.StandardButton'] = ..., defaultButton: 'QMessageBox.StandardButton' = ...) -> 'QMessageBox.StandardButton': ...
@staticmethod
def warning(parent: QWidget, title: str, text: str, buttons: typing.Union['QMessageBox.StandardButtons', 'QMessageBox.StandardButton'] = ..., defaultButton: 'QMessageBox.StandardButton' = ...) -> 'QMessageBox.StandardButton': ...
@staticmethod
def question(parent: QWidget, title: str, text: str, buttons: typing.Union['QMessageBox.StandardButtons', 'QMessageBox.StandardButton'] = ..., defaultButton: 'QMessageBox.StandardButton' = ...) -> 'QMessageBox.StandardButton': ...
@staticmethod
def information(parent: QWidget, title: str, text: str, buttons: typing.Union['QMessageBox.StandardButtons', 'QMessageBox.StandardButton'] = ..., defaultButton: 'QMessageBox.StandardButton' = ...) -> 'QMessageBox.StandardButton': ...
在使用中根据弹窗等级来设置。
