add column assert!!

9 years 9 months ago #1 by Kwangho Kim
i use QtitanDataGrid 3.3.2 and i'm very disappoint qtitandatagrid's bugs.

In all examples, Qtitandatagrid was setModel with autocreatecolumn = true. Then, no problem.

but, when setModel with autocreatecolumn = false, addcolumn assert. ( In GridBandedTableView, not GridTableView )


CManageUnapproveSWUI::CManageUnapproveSWUI( QWidget* parent /*= 0 */ )
: QDialog( parent, Qt::FramelessWindowHint )
{
ui.setupUi( this );

ui.tblUnapproveSW->setViewType( Qtitan::Grid::BandedTableView );
auto tblAmalgamation = ui.tblUnapproveSW->view< Qtitan::GridBandedTableView >();
auto& tblOptions = tblAmalgamation->options();

tblAmalgamation->setModel( &_amalgamationItemModel, QModelIndex(), false );

tblOptions.setGroupsHeader( false );
tblOptions.setBandsHeader( false );
tblOptions.setColumnAutoWidth( true );
tblOptions.setRowAutoHeight( true );

_amalgamationItemModel.init( tblAmalgamation );
_amalgamationItemModel.createColumns();
}

void CManageUnapproveSWModel::createColumns()
{
if( m_view == NULLPTR )
return;

if( m_view->getColumnCount() > 0 )
return;

Qtitan::GridBandedTableView* spView = qobject_cast<Qtitan::GridBandedTableView*>(m_view);

spView->removeColumns();

auto spProcessBand = spView->addBand( tr( "??????" ) );
auto spBlockInfoBand = spView->addBand( tr( "????" ) );
auto spApproveInfoBand = spView->addBand( tr( "????" ) );

spProcessBand->setBandIndex( 0 );
spBlockInfoBand->setBandIndex( 1 );
spApproveInfoBand->setBandIndex( 2 );

colBase = spView->addColumn( 0 ); // assert!!
if( colBase == NULLPTR )
return;

colBase->setBandIndex( 0 );
colBase->setRowIndex( 0 );
colBase->setRowSpan( 2 );

}

Thanks for this bug report. To fix this issue with banded view please do the following:
    spView ->beginUpdate();
    colBase = spView->addColumn(0);
    colBase->setBandIndex(0);
    ...............
    ...............
    view->endUpdate();
