Trouble with wxListCtrl


C

chauhan

Hi,

I am new to pogramming.

I have written a small program which retrieves emails from server,
unless all the messages are loaded only then it displays on screen
properlely. Whole thing works fine if I use events to activate
logMail() after start but I don't know how to activate an event at the
start (witout pressing mouse or menu key) as I want this to load
messages at the start of the program.

I am also having problem with statement
self.list.GetItemText(self.currentItem). The statement
self.currentItem gives the current selected item position on listctrl
this statement works fine in wxPanel (demo example wxlistctrl in
wxPython) and not with
wxFrame which I am using now as I want menubar in my application. Can
some body tell me how to get the current selected items position in
wxListCtrl with wxFrame? Same kind of problem with wxPoint(self.x,
self.y) but I can use wxGetMousePosition().

Also I would like to know how to check if internet connection is on.

Thanks in advance

Chauhan

I am also having problem with statement
self.list.GetItemText(self.currentItem). The statement
self.currentItem gives the current selected item position on listctrl
this statement works fine in wxPanel (demo example wxlistctrl in

Hi, wxPanel or wxFrame has nothing to do with self.currentItem, this
attribute is set to 0 in TestListCtrlPanel.PopulateList in mentioned
example, they register a handler for item selection

EVT_LIST_ITEM_SELECTED(self, tID, self.OnItemSelected)

and in this hanler they set it to currently selected item:

def OnItemSelected(self, event):
##print event.GetItem().GetTextColour()
self.currentItem = event.m_itemIndex
# [...]

This method tracks user selection, the other way is to find the
selected item when you need it:

currentItem = self.list.GetNextItem(
-1, wxLIST_NEXT_ALL, wxLIST_STATE_SELECTED)

this finds first selected item (first after -1).
