Ich würde gerne wissen ob ihr mir weiterhelfen könnt.
Ich würde gerne wissen ob es eine Möglichkeit gibt, das er nur nach ganzen Wörtern schaut. wenn ich nun "Wer" in der Tabelle stehen habe, sagt er mir bei "W" das es bereits in der Tabelle existiert.
Meine View.cpp :
Code: Alles auswählen
void View::init()
{
meinModel= new Model();
QTableView *meineView=new QTableView( this );
meineView->setModel(meinModel);
QWidget *mywidget= new QWidget(this);
QPushButton* btnaddtotable = new QPushButton( "Add to Table",this);
btnaddtotable->setGeometry(50,20,100,40);
QObject::connect ( btnaddtotable, SIGNAL ( clicked() ), this , SLOT(pushButtonClicked())) ;
meineView->setObjectName(QStringLiteral("Tabelle"));
meineView->setGeometry(QRect(20, 100, 361, 191));
txtname = new QLineEdit(mywidget);
txtname->setObjectName(QStringLiteral("txtname"));
txtname->setGeometry(QRect(20, 30, 151, 31));
txtvalue = new QLineEdit(mywidget);
txtvalue->setObjectName(QStringLiteral("textEdit"));
txtvalue->setGeometry(QRect(230, 30, 151, 31));
label = new QLabel ("Name: ", mywidget );
label->setObjectName(QStringLiteral("label"));
label->setGeometry(QRect(20, 10, 61, 20));
label_2 = new QLabel ("Value ", mywidget );
label_2->setObjectName(QStringLiteral("label_2"));
label_2->setGeometry(QRect(235, 10, 51, 20));
btnaddtotable->setObjectName(QStringLiteral("pushButton"));
btnaddtotable->setGeometry(QRect(160, 70, 75, 23));
this->setGeometry(500,500,400,350);
// zum sortieren
sort_filter = new QSortFilterProxyModel(this);
sort_filter->setSourceModel(meinModel);
//sortiert die erste reihe
sort_filter->sort (0);
meineView->setModel (sort_filter);
//zum überprüfen ob vorhanden
sort_filter->setSourceModel(meinModel);
}
void View::pushButtonClicked()
{ QMessageBox msb;
//sort_filter->setFilterFixedString(txtname->text());
QModelIndexList indexes = meinModel->match(meinModel->index(0,0), Qt::DisplayRole,QVariant::fromValue(txtname->text()) );
if (indexes.size() == 0 )
{
this->setSortingEnabled(false);
meinModel->setData(txtname->text(),txtvalue->text());
this->setSortingEnabled(true);
} else
