bind label and entry text with return key - metulburr - Aug-14-2018
Im going through a tutorial comparing tkinter with wxpython, and this is the code. My problem is line 14 where it binds the label and entry text when return is pressed. It should change the label but it does not. wx.EVT_TEXT_ENTER appears to be the correct flag for this, but i am not sure why it does not work as described. My initial thought was this is out of date, but other examples from googling follow the same method.
import wx
class simpleapp_wx(wx.Frame):
def __init__(self,parent,id,title):
wx.Frame.__init__(self,parent,id,title)
self.parent = parent
self.initialize()
def initialize(self):
sizer = wx.GridBagSizer()
self.entry = wx.TextCtrl(self,-1,value=u"Enter text here.")
sizer.Add(self.entry,(0,0),(1,1),wx.EXPAND)
self.Bind(wx.EVT_TEXT_ENTER, self.OnPressEnter, self.entry)
button = wx.Button(self,-1,label="Click me !")
sizer.Add(button, (0,1))
self.Bind(wx.EVT_BUTTON, self.OnButtonClick, button)
self.label = wx.StaticText(self,-1,label=u'Hello !')
self.label.SetBackgroundColour(wx.BLUE)
self.label.SetForegroundColour(wx.WHITE)
sizer.Add( self.label, (1,0),(1,2), wx.EXPAND )
sizer.AddGrowableCol(0)
self.SetSizerAndFit(sizer)
self.SetSizeHints(-1,self.GetSize().y,-1,self.GetSize().y );
self.entry.SetFocus()
self.entry.SetSelection(-1,-1)
self.Show(True)
def OnButtonClick(self,event):
self.label.SetLabel( self.entry.GetValue() + " (You clicked the button)" )
self.entry.SetFocus()
self.entry.SetSelection(-1,-1)
def OnPressEnter(self,event):
self.label.SetLabel( self.entry.GetValue() + " (You pressed ENTER)" )
self.entry.SetFocus()
self.entry.SetSelection(-1,-1)
if __name__ == "__main__":
app = wx.App()
frame = simpleapp_wx(None,-1,'my application')
app.MainLoop()

i think i figured it out.
apparently you have to have wx.TE_PROCESS_ENTER as a style for the textctrl
self.entry = wx.TextCtrl(self,-1,value=u"Enter text here.", style=wx.TE_PROCESS_ENTER)
sizer.Add(self.entry,(0,0),(1,1),wx.EXPAND)
self.Bind(wx.EVT_TEXT_ENTER, self.OnPressEnter, self.entry)
