Drawing with wxClientDC

[Alejandro]

Hi,
    I tried with your solution, but it doesn't work. I'm using a 
wxSimpleHtmlListBox and not a wxFrame like I said, I' don't know if this 
could make any difference.
Now my code is:
       wxClientDC *pclientdc = new wxClientDC(plist);
       pclientdc->DrawLine(0, coord_y, plist->GetSize().GetX(), coord_y);
       delete pclientdc;
       plist->Refresh();

where plist is a pointer to a wxSimpleHtmlListBox.
I tried, setting to the wxSimpleHtmlListBox.the background style, I 
mean, plist->SetBackgroundStyle(wxBG_STYLE_CUSTOM) and still doesn't work.

Any idea?

Regards.
Alejandro.
