C++ (Cpp) GET_HEADER_INFO Examples

Example #1

File: belge_kernel.cpp Project: coolixwebgraphics/FRAMEWORK

void BELGE_KERNEL::GET_VARIABLES ()
{
    if ( m_mode EQ PRINT_TEST_VARS OR m_mode EQ PRINT_TEST_XXX ) {
        return;
    }

    m_header_variables.clear();
    GET_HEADER_INFO();

    // Satir sayisi kadar stringlist ayarla
    if (m_line_variables NE NULL) {
        delete m_line_variables;
    }
    m_line_variables     = new QStringList[m_row_count];
    m_kullanilan_satir_sayisi = 0;

    for (int i = 0 ; i < m_row_count ; i++) {
        m_kullanilan_satir_sayisi = i;
        GET_LINE_INFO();
    }

    m_footer_variables.clear();
    GET_FOOTER_INFO();
}
