How to get text for Tableview to Combobox ?

[hohoanganh205]

I loaded a Form with tableview have data (data loaded from MYSQL ), when a row on tableview is selected, data from each column will display on LineEdit ( Mã DL, Tên DL, Email, Địa chỉ, Điện thoại, Tiền nợ ) and also display on DateEdit ( Ngà y nháº*n ) but can not display on 2 Combobox ( Loại DL, Tên quáº*n ). See pic :

Combobox "Loại DL, Tên quáº*n" display " 1, Quan 1" is default Items, can not diaplay for tableview. These are code :

connect(ui.tableView->selectionModel(),SIGNAL(selectionChanged(const QItemSelection &,const QItemSelection &)),this,SLOT(selectItem(const QItemSelection &,const QItemSelection &)));
ui.tableView->selectRow(0);
 
 
void QuanLyDaiLy::selectItem(QItemSelection selected,QItemSelection)
{
	QSqlQueryModel *QModel;
	QModelIndexList items = selected.indexes();
	ui.txtMaDL->setText(QModel->data(items[0],Qt::DisplayRole).toString());
	ui.txtTenDL->setText(QModel->data(items[1],Qt::DisplayRole).toString());
	ui.txtEmail->setText(QModel->data(items[2],Qt::DisplayRole).toString());
	ui.txtDiaChi->setText(QModel->data(items[3],Qt::DisplayRole).toString());
 
	QModelIndexList mySelection4 = ui.tableView->selectionModel()->selectedRows(4);
		QDate data4;
		foreach(QModelIndex selectedIndex4, mySelection4)
			data4 = selectedIndex4.data(0).toDate();
		ui.dtNgayNhan->setDate(data4);
 
	ui.cbLoaiDL->itemText(QModel->data(items[5],Qt::DisplayRole).toInt());
	ui.cbTenQuan->setCurrentIndex(QModel->data(items[6],Qt::DisplayRole).toInt());
 
	ui.txtDienThoai->setText(QModel->data(items[7],Qt::DisplayRole).toString());
	ui.txtTienNo->setText(QModel->data(items[8],Qt::DisplayRole).toString());
}

connect(ui.tableView->selectionModel(),SIGNAL(selectionChanged(const QItemSelection &,const QItemSelection &)),this,SLOT(selectItem(const QItemSelection &,const QItemSelection &)));
ui.tableView->selectRow(0);


void QuanLyDaiLy::selectItem(QItemSelection selected,QItemSelection)
{
	QSqlQueryModel *QModel;
	QModelIndexList items = selected.indexes();
	ui.txtMaDL->setText(QModel->data(items[0],Qt::DisplayRole).toString());
	ui.txtTenDL->setText(QModel->data(items[1],Qt::DisplayRole).toString());
	ui.txtEmail->setText(QModel->data(items[2],Qt::DisplayRole).toString());
	ui.txtDiaChi->setText(QModel->data(items[3],Qt::DisplayRole).toString());

	QModelIndexList mySelection4 = ui.tableView->selectionModel()->selectedRows(4);
		QDate data4;
		foreach(QModelIndex selectedIndex4, mySelection4)
			data4 = selectedIndex4.data(0).toDate();
		ui.dtNgayNhan->setDate(data4);

	ui.cbLoaiDL->itemText(QModel->data(items[5],Qt::DisplayRole).toInt());
	ui.cbTenQuan->setCurrentIndex(QModel->data(items[6],Qt::DisplayRole).toInt());

	ui.txtDienThoai->setText(QModel->data(items[7],Qt::DisplayRole).toString());
	ui.txtTienNo->setText(QModel->data(items[8],Qt::DisplayRole).toString());
}

To copy to clipboard, switch view to plain text mode 

ui.cbLoaiDL->itemText(...
ui.cbTenQuan->setCurrentIndex(..

itemText() and setCurrentIndex() functions are not work , which functions I can use ?

Thanks for help !

See QDataWidgetMapper, which is the "right" way to do what you want.

And no wonder that setCurrentIndes is not working. Debug what QModel->data(items[6],Qt:isplayRole) returns! It is "quan 2" which is not a number....
