ListCtrl in Dialog: list_item_activated == send ID_OK event - how ?

wxPython Users

Hi,

I have a list inside a dialog (patients to select from
matching a search term). The dialog also has a button
"Select" with ID_OK and a button "Cancel" with ID_CANCEL.

The "Select" button is set to be the default button. The
list is set to be focussed initially.

All this was accomplished with the help of wxGlade.

Hitting "Cancel" or pressing ESC dutifully closes the dialog
and returns ID_CANCEL. Hitting "Select" closes the dialog,
too, and returns ID_OK from EndModal() as is expected.

Now I want my users to be able to simply hit ENTER on a list
item or double-click on one and also close the dialog
returning ID_OK. Catching the list_item_activated event on
ENTER or double-click works fine but how do I go about
closing the dialog and returning ID_OK ? I have tried
calling the dialogs OnOK() as was mentioned in the docs but
it doesn't seem to exist. Neither does OnOk().

I could certainly do

if IsModal():
  self.EndModal(wx.ID_OK)
else:
  self.Close(wx.ID_OK)

or a similar dance. I am wondering, however, whether there's
an easier/more elegant way, though, like "simulating"
pressing the "Select" button - or IOW sending the
corresponding button press event.

This is on:

python-wxgtk2.6:
  Installiert:2.6.3.2.1.5
  Mögliche Pakete:2.6.3.2.1.5
  Versions-Tabelle:
*** 2.6.3.2.1.5 0
        990 ftp://ftp.gwdg.de testing/main Packages
        100 /var/lib/dpkg/status

python:
  Installiert:2.4.3-11
  Mögliche Pakete:2.4.3-11
  Versions-Tabelle:
*** 2.4.3-11 0
        990 ftp://ftp.gwdg.de testing/main Packages

     2.3.5-2 0

Thanks,
Karsten

This is the correct way.

corresponding button press event.

But this can be done too, and IIRC is used internally in a couple places. Something like creating a wx.CommandEvent with an ID of wx.ID_OK and a type of wx.wxEVT_COMMAND_BUTTON_CLICKED, and then send it with self.GetEventHandler().ProcessEvent(event)
