Crash on the wxLog->Flush

[ONEEYEMAN]

Hi, ALL,
Never needed to wx logging, before...

Here is my code:

Code: Select all

class Dlg : public wxDialog
{
public::
    Dlg();
    ~Dlg();
private::
    std::ofstream log;
    wxLog **logger;
};

Dlg::Dlg()
{
    log.open( "mylogfile.log" );
    logger = new wxLogStream( &log );
    wxLog::SetActiveTarget( logger );
}

Dlg::~Dlg()
{
    log.close();
}

The dialog shows up, performs what needs to be done, but when I click "Cancel" button to cancel the dialog, I'm getting a crush on the wxLog->Flush().

What am I doing wrong?

Thank you.

You need to delete the new logtarget first and restore the old one.

Code: Select all

  wxLog* oldLog = wxLog::SetActiveTarget(new wxLogStderr);

  [...] using log here

  delete wxLog::SetActiveTarget(oldLog);
