2. 轮值。 仅仅显示一个框架即可适用
原标题:purpose of wx.App when just showing a frame is enough

What is the use of the wx.App class (apart from what the documentation says), when you can just create a frame and .Show(True) it?

页: 1 App 班级被使用,或为什么要打你打造一个框架,只是显示它?

最佳回答

http://www.un.org。 申请:如果你试图在制作电灯前即刻上课,就会失败:

>>> import wx
>>> frame = wx.Frame(None)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:Python26libsite-packageswx-2.8-msw-unicodewx\_windows.py", line 505, in __init__
    _windows_.Frame_swiginit(self,_windows_.new_Frame(*args, **kwargs))
wx._core.PyNoAppError: The wx.App object must be created first!

永远会出现一种,只有一种。 应用. 证实其先天性,创造窗户等。

问题回答

The wx. 申请是在幕后进行的,无法使申请工作。 它是主要的循环,也就是用户需要做些什么,然后作出反应。 你们必须这样做。 正如Fogle Bird提到的那样。 顺便说一句,你应该拥有一个以上。 这样做将产生不容置疑的问题,如果它完全发挥作用的话。

二级轮椅 如果你需要做一些额外工作,则适用是正当的。 这适用于启动与数据库的联系或连接网络,在发射主机之前装载一些外部数据/档案。

class MyApp(wx.App):
    def OnInit(self):
        # Do some work here
        return True
    def __init__(self):
        main_frame = MyFrame(*args, **kwargs)
        main_frame.Show()
    def OnExit(self):
        # Clean up and close the resources from the OnInit() method
