如何使用按钮打开新窗口-尊龙凯时

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.
