Bug #7023 » updateModel_pseudo.cpp

"Pseudo code" showing how the data is updated in the table. - Christopher Bilberg, 05/03/2019 10:10 AM

 

// Initialize model and WTableView
Wt::WStandardItemModel* model = new WStandardItemModel(container);
model->insertColumns(0, headers_.size());
Wt::WTableView* table = new WTableView(container);
table->setModel(model_);
table_->setColumnResizeEnabled(true);
table_->setColumnAlignment(0, AlignCenter);
table_->setHeaderAlignment(0, AlignCenter);
table_->setAlternatingRowColors(false);
table_->setRowHeaderCount(1);
table_->setSelectionMode(ExtendedSelection);
table_->setMaximumSize(table_->width(),
WLength(TABLE_HEIGHT, WLength::Unit::Pixel));

// Update function triggered by postAll on the server
void updateTableView() {
int row = 0;
for (const auto& item : dataToBeInserted) {
//... DO SOME STUFF...
model->insertRow(row++);
for(int col = 0; col < item.columns(); col++) {
model->setData(row, col, item.value(col));
model_->setData(row, col, item.styleclass, StyleClassRole);
}
}
int rowCount = model_->rowCount();
if (rowCount > MAX_NUMBER_OF_ROWS) {
model_->removeRows(MAX_NUMBER_OF_ROWS, rowCount - MAX_NUMBER_OF_ROWS);
}
}
