问题描述
如何打开一个允许我从以下代码中选择时间的新窗口?我尝试使用connect函数连接到windows2，但似乎出现错误.
how do i open a new window which allows me to select the time from the following code? i tried to use connect function to connect to windows2 however it appears that there is an error.
我想通过 dropbox 选择时间，我可以在上午 10 点、上午 11 点等之前选择时间.有谁知道您也可以如何实现这一点?
i would like to select time by a dropbox where i could choose time by 10 am, 11 am, ect.. does anyone know how you could implement this as well?
class window(qmainwindow):
def __init__(self):
super().__init__()
self.label = qlabel()
self.calendar = qcalendarwidget()
self.title="select date from calendar"
self.left = 600
self.top = 300
self.width = 500
self.height = 480
self.iconname = "home.png"
self.setwindowtitle(self.title)
self.setwindowicon(qtgui.qicon(self.iconname))
self.setgeometry(self.left, self.top, self.width, self.height)
self.proceedbutton = qpushbutton("proceed to select time", self)
self.proceedbutton.setgeometry(290, 430, 190, 40)
self.proceedbutton.settooltip("start the session
")
self.proceedbutton.clicked.connect(self.window2)
self.hide()
self.backbutton = qpushbutton("back", self)
self.backbutton.setgeometry(200, 430, 80, 40)
self.backbutton.settooltip("start the session
")
self.calendar()
self.show()
def calendar(self):
calendarvbox = qvboxlayout()
self.calendar.setgridvisible(true)
self.label.setfont(qtgui.qfont("sanserif", 10))
self.label.setstylesheet('color:black')
calendarvbox.addwidget(self.calendar)
calendarvbox.addwidget(self.label)
self.setlayout(calendarvbox)
self.calendar.selectionchanged.connect(self.onselectionchanged)
def window2(self):
self.label = qlabel("select time", self)
self.label.move(200,430)
self.setwindowtitle("select time")
self.setgeometry(self.left, self.top, self.width, self.height)
self.show()
def onselectionchanged(self):
ca = self.calendar.selecteddate()
self.label.settext(ca.tostring())
app = qapplication(sys.argv)
window = window()
sys.exit(app.exec())
推荐答案
开始使用layouts！
没有父级的小部件 - 有一个窗口.
a widget without a parent - there is a window.
