wxPython隐藏和显示面板 [英] wxPython hide and show panel

问题描述

我正在创建一个Python应用程序，该应用程序需要在启动时登录.我想要一个主面板来保存我的登录面板，成功登录后将隐藏登录面板，并显示主wx.Notebook.以下代码可以工作，但是如果在登录面板中成功重新登录并转到主wx.Notebook后，请重新调整应用程序的大小，则wx.Notebook不适合屏幕尺寸.如果我在主wx.Notebook中再次调整大小，则主wx.Notebook将适合窗口.如何获得主要的wx.Notebook自动调整到窗口的大小?

I am creating a Python application that requires a login on start up. I want to have a main panel that will hold my login panel and on successful login the login panel will hide and the main wx.Notebook will show. The following code works, but if in the login panel I re-size the application, after I successfully login and go to the main wx.Notebook the wx.Notebook does not fit the size of the screen. If I resize again while in the main wx.Notebook the main wx.Notebook will fit the window. How do I get the main wx.Notebook to automatically re-size to the window?

推荐答案

知道了！我试图使用Layout()重绘框架，但是我需要使用Layout()重绘BoxSizer. 我在登录按钮上添加了以下代码:

Got it! I was trying to redraw the frame with Layout(), but I needed to redraw the BoxSizer with Layout() I added the following code to the login button:

def EvtLoginBtn(self,e):
    self.nb.Show()
    self.mainLogin.Hide()
    self.mainSizer.Layout()
