wxPython hide and show panel
10,738
Solution 1
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()
Solution 2
Call the Layout() method of the Frame and Panel like this
def EvtLoginBtn(self,e):
self.nb.Show()
self.mainLogin.Hide()
self.Layout()
self.nb.Layout()
The last call is probably not needed. Just check the program without it as well. The Layout() method redraws the Frame or Panel or whichever widget it is a method of.
UPDATE
Your code is obviously very big and has several other parts which I do not know. Anyways, here's something that I came up with, along the lines of the code you have provided, to show how you can do this. Hope this helps:
Main.py
import wx
from LoginPanel import LoginPanel
class MyFrame ( wx.Frame ):
def __init__( self, parent ):
wx.Frame.__init__ ( self, parent, id = wx.ID_ANY, title = u"Something something", pos = wx.DefaultPosition, size = wx.Size( 300,300 ), style = wx.DEFAULT_FRAME_STYLE|wx.TAB_TRAVERSAL )
self.SetSizeHintsSz( wx.DefaultSize, wx.DefaultSize )
BoxSizer0 = wx.BoxSizer( wx.VERTICAL )
# Add login panel
self.login_panel = LoginPanel(self)
BoxSizer0.Add(self.login_panel, 1, wx.EXPAND | wx.ALL, 0)
# Add notebook panel and its pages
self.nb = wx.Notebook( self, wx.ID_ANY, wx.DefaultPosition, wx.DefaultSize, 0 )
self.nb_subpanel1 = wx.Panel( self.nb, wx.ID_ANY, wx.DefaultPosition, wx.DefaultSize, wx.TAB_TRAVERSAL )
self.nb.AddPage( self.nb_subpanel1, u"something", False )
self.nb_subpanel2 = wx.Panel( self.nb, wx.ID_ANY, wx.DefaultPosition, wx.DefaultSize, wx.TAB_TRAVERSAL )
self.nb.AddPage( self.nb_subpanel2, u"something else", False )
BoxSizer0.Add( self.nb, 1, wx.EXPAND |wx.ALL, 0 )
# Adds a logout button
self.logout_button = wx.Button( self, wx.ID_ANY, u"Logout", wx.DefaultPosition, wx.DefaultSize, 0 )
BoxSizer0.Add( self.logout_button, 0, wx.ALIGN_CENTER|wx.ALL, 5 )
# Hide nb and logout button
self.nb.Hide()
self.logout_button.Hide()
self.SetSizer( BoxSizer0 )
self.Layout()
self.Centre( wx.BOTH )
self.Show()
# Connect Events
self.logout_button.Bind( wx.EVT_BUTTON, self.on_logout )
# Virtual event handlers, override them in your derived class
def on_logout( self, event ):
self.nb.Hide()
self.logout_button.Hide()
self.login_panel.Show()
self.Layout()
if __name__ == "__main__":
app = wx.App()
MyFrame(None)
app.MainLoop()
LoginPanel.py
import wx
class LoginPanel ( wx.Panel ):
def __init__( self, parent ):
wx.Panel.__init__ ( self, parent, id = wx.ID_ANY, pos = wx.DefaultPosition, size = wx.Size( 300,300 ), style = wx.TAB_TRAVERSAL )
BoxSizer01 = wx.BoxSizer( wx.VERTICAL )
self.login_button = wx.Button( self, wx.ID_ANY, u"Login", wx.DefaultPosition, wx.DefaultSize, 0 )
self.login_button.SetDefault()
BoxSizer01.Add( self.login_button, 0, wx.ALIGN_CENTER|wx.ALL, 5 )
self.SetSizer( BoxSizer01 )
self.Layout()
# Connect Events
self.login_button.Bind( wx.EVT_BUTTON, self.on_login )
# Virtual event handlers, overide them in your derived class
def on_login( self, event ):
self.Hide()
self.Parent.nb.Show()
self.Parent.logout_button.Show()
self.Parent.Layout()

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?
