add a new row in grid was created by jia
Hello,
I want to add a new row in grid and show them after added.
my code like these
int xSimGridCtrl::addRow()
{
	//bool inc = m_model->insertRow(0);

	Qtitan::GridTableView* view = this->view<Qtitan::GridTableView>();	
	view->beginUpdate();
	int modelRowIndex = 0;// view->modelController()->model()->rowCount();
	view->modelController()->beginAddRow(modelRowIndex); // To be here to value does not be catched by the filter.
	bool suc = view->modelController()->insertModelRow(modelRowIndex);
	view->modelController()->endAddRow();	
	int rowIndex = view->modelController()->ensureVisible(modelRowIndex);
	view->endUpdate();
	view->requestUpdateLayout();
	this->update();
	return rowIndex;
}

The new row didn't show immediately . It can be show after I click column for sorting.

It is not a good idea to use low-level grid API to add the row. You can add the row directly to the model and then scroll to it.
    GridTableView* view = m_grid->view<Qtitan::GridTableView>();
    view->model()->insertRow(0);
    GridRow row = view->modelController()->getGridRowByModelRow(0);
    view->scrollToRow(row);
