warnings in release Mode

[Etienne de Foras]

Hello,

First, thanks for this nice work, it is very usefull for my software.

I compiled wxmathplot in release Mode(gcc 4.3.2_2 under win32), all warnings activated, I have some questions:

Line 654 in mathplot.cpp: (warning is : statement has no effect)

if (m_drawOutsideMargins)
            X_BORDER_SEPARATION;

should it be?:

if (m_drawOutsideMargins)
             orgy =  X_BORDER_SEPARATION;
     

line 858: (startPx is unused ) potential bug here?
    wxCoord startPx = m_drawOutsideMargins ? 0 : w.GetMarginLeft();

a lot of unused events:

like in:

void mpWindow::OnLockAspect(wxCommandEvent &event)
{
    LockAspect( !m_lockaspect );
}

so I hadded a (void) to tell the compiler to ignore it:

void mpWindow::OnLockAspect(wxCommandEvent &event)
{
   (void)event;
    LockAspect( !m_lockaspect );
}

Sorry, I didn't commit these, since I don't want to break stuffs...But I can send the file mathplot.cpp if you want.

Thanks again !

Etienne
