I searched a lot to do this but nothing of what I tried work. Now, as last attemp, I am trying with pubsub, but I can get nothing of worth, that's why I am asking for help now :). This is an minimal (as best I can do it :)) example of what I want. PanelB gets information in a list (box), and when someone of the items is selected, PanelA should change according to him. Thank you in advance.
from wx.lib.pubsub import Publisher
import wx
global name
name = 'none, please select an item'
class PanelA(wx.Panel):
def __init__(self, parent, name):
wx.Panel.__init__(self, parent)
self.hbox = wx.BoxSizer(wx.HORIZONTAL)
self.vbox = wx.BoxSizer(wx.VERTICAL)
str = name
txt = wx.StaticText(self, -1, "You have selected " + str, (20, 100))
self.hbox.Add(txt, 1, wx.EXPAND | wx.ALL, 20)
class PanelB(wx.Panel):
def __init__(self, parent):
wx.Panel.__init__(self, parent)
self.hbox = wx.BoxSizer(wx.HORIZONTAL)
self.vbox = wx.BoxSizer(wx.VERTICAL)
self.listbox = wx.ListBox(self, -1)
self.hbox.Add(self.listbox, 1, wx.EXPAND | wx.ALL, 20)
self.btnPanel = wx.Panel(self, -1)
self.new = wx.Button(self.btnPanel,label='Add', size=(90, 30))
self.new.Bind(wx.EVT_BUTTON, self.NewItem)
self.vbox.Add((-1, 20))
self.vbox.Add(self.new)
self.btnPanel.SetSizer(self.vbox)
self.hbox.Add(self.btnPanel, 0.6, wx.EXPAND | wx.RIGHT, 20)
self.SetSizer(self.hbox)
self.Bind(wx.EVT_LISTBOX, self.onSelect)
def onSelect(self, event):
name_selected = self.listbox.GetStringSelection()
Publisher().sendMessage(("ListBox"), name_selected)
def NewItem(self, event):
text = wx.GetTextFromUser('Nombre', 'Programa a salvar')
if text != '':
self.listbox.Append(text)
class MainFrame(wx.Frame):
def __init__(self, parent, id, title, *args, **kw):
wx.Frame.__init__(self, parent, id, title, size = (800,300))
self.splitter = wx.SplitterWindow(self, -1, style=wx.SP_3D)
self.lc1 = PanelB(self.splitter)
Publisher().subscribe(self.OnSelect, ("ListBox"))
self.lc2 = PanelA(self.splitter, name)
self.splitter.SplitVertically(self.lc1, self.lc2)
sizer = wx.BoxSizer(wx.HORIZONTAL)
sizer.Add(self.splitter, 1, wx.EXPAND)
self.SetSizer(sizer)
self.Centre()
self.Show(True)
def OnSelect(self, name_selected):
name = name_selected
#I stucked here
if __name__ == "__main__":
app = wx.App()
frame = MainFrame(None,-1,'Mi aplicacion')
app.MainLoop()
This is not beautiful solution, basically you can just destroy PanelA then call that panel again, maybe like this:
def OnSelect(self, name_selected):
self.lc2.Destroy()
self.lc2 = PanelA(self.splitter, name_selected.data)
Hope this can help.
UPDATE (08/24/2012): added some code
Okey we should not destroy the panel. I'm using your code and modified it a bit. I removed global variable name and added changeName(name) function to PanelA so that when MainFrame.onSelect() is called it will call changeName(). It's not beautiful but hope this can help.
