C++ (Cpp) FileManager::copyFile Examples

Example #1

File: lnkproperties.cpp Project: opieproject/opie

bool LnkProperties::copyFile( DocLnk &newdoc )
{
    const char *linkExtn = ".desktop";
    QString fileExtn;
    int extnPos = lnk->file().findRev( '.' );

	}

    }
    newdoc.setFile( fn + fileExtn );
    newdoc.setLinkFile( fn + linkExtn );

    // Copy file
    FileManager fm;
    if ( !fm.copyFile( *lnk, newdoc ) )
	return FALSE;
    return TRUE;
