[SOLVED] Insert row from Qtableview to another
-
Hi, every body
i have a probleme with inserting a row from a table call tableProduct to another table call tableSalle
when the user click entre key in the first table "tableProduct"
i can't figured out, how this work
i start using
@my@SalleModel->insertRow(tableProduct->currentIndex().row()) ;@
but not working
-
Hi,
If you want some hints you'll have to give more information like: the code you are using to add the row and set the data, what result you are having etc...
-
@ bool Mymodel::insertRows(int position, int rows, const QModelIndex &parent)
{
beginInsertRows(QModelIndex(), position, position+rows-1);
// i want to get the event when the user click "Keydown"
if (true)
{
// we add row with empty fields to allow user to fill them
}endInsertRows(); return true;}@
her is an image that explain exacly what means!http://imageshack.us/photo/my-images/577/2ng9.png/(sell)!

The link to your picture is broken. But it's not critical. If I've followed you correctly you are using a Sql database so just use a QSqlTableModel, they are designed for that and don't need to be subclassed (if you are not doing more than just modify the content of the database)
-
Qsqltablemodel not working for me
check this image, my english is not good, to expalin more
-
If I understood your picture correctly, you want some sort of database record editor. Then use a QTableWidget, a QSqlTableModel would require that you have a table in your database for this.
-
Well then, use a QTableWidget for the editing part, unless you have a special table in your database for that.

i want to like the video,

when the user entre data new row created
i can't post so i have modified this post
i can't control the addition of rows
her is my code
@#include "mainwindow.h"
MainWindow::MainWindow(QWidget *parent)
: QWidget(parent)
{tableNouveau = new QTableWidget; tableNouveau->setRowCount(1); tableNouveau->setColumnCount(5); QStringList list ; list <<"N°"<< "Désignation" << "Qte" << "Prix/U" << "Totale" ; tableNouveau->setHorizontalHeaderLabels(list); connect(tableNouveau,SIGNAL(cellClicked(int,int)),this,SLOT(test(int,int))) ; QVBoxLayout *layoutPrincipale = new QVBoxLayout ; layoutPrincipale->addWidget(tableNouveau); setLayout(layoutPrincipale);}
void MainWindow::test(int row, int col)
{
// if(!tableNouveau->item(row,col)->text().isEmpty())
if(col==1)
{
tableNouveau->insertRow(1);
}}
MainWindow::~MainWindow()
{}

When the user enters data, the QTableWidget will emit some "signals":http://qt-project.org/doc/qt-5.1/qtwidgets/qtablewidget.html#signals. You should create your own slot to handle the signal(s) that you want.
Connect the signal to your slot. Inside your slot, call call "QTableWidget::insertRow()":http://qt-project.org/doc/qt-5.1/qtwidgets/qtablewidget.html#insertRow

i can’t control the addition of rows
her is my code
@
#include "mainwindow.h"MainWindow::MainWindow(QWidget *parent) : QWidget(parent) { tableNouveau = new QTableWidget; tableNouveau->setRowCount(1); tableNouveau->setColumnCount(5); QStringList list ; list <<"N°"<< "Désignation" << "Qte" << "Prix/U" << "Totale" ; tableNouveau->setHorizontalHeaderLabels(list); connect(tableNouveau,SIGNAL(cellClicked(int,int)),this,SLOT(test(int,int))) ; QVBoxLayout *layoutPrincipale = new QVBoxLayout ; layoutPrincipale->addWidget(tableNouveau); setLayout(layoutPrincipale); } void MainWindow::test(int row, int col) { // if(!tableNouveau->item(row,col)->text().isEmpty()) if(col==1) { tableNouveau->insertRow(1); } } MainWindow::~MainWindow() { }@
-
What do you mean by "I can't control" ?
The code here will add a new row at row number 1 each time you click on a cell in the column 1.
-
Then change 1 by tableNouveau->rowCount()
-
Wow, this works
Now, what i want exactly is
the user isn't able to add row until he fills all cells
then he clicks "Key_Down" to add new row ( so her i will catch Qkeypressevent)
Plz give somme hints, so i will try to implement this my selef and render the code for you to correct me
thank's a lot SGaist

i have tried to inherif from Qtablewidget and override keypressevent function
i have declared keypressevent function as signal
it works with this condition
@if ( event->key() == Qt::key_Down)@but when i add more conditions the app crached
her is my code
customtablewidget class @class MonTableauWidget : public QTableWidget
{
Q_OBJECT
public:
explicit MonTableauWidget(QWidget *parent = 0);signals:
void keyPressEvent(QKeyEvent *event);
public slots:};
@the main of classe @#include "montableauwidget.h"
MonTableauWidget::MonTableauWidget(QWidget *parent) :
QTableWidget(parent)
{}
@
and her is my main where i tried to connect siganl with slot @#include "dialog.h"
Dialog::Dialog(QWidget *parent)
: QWidget(parent)
{
layoutPrincipale = new QVBoxLayout(this);
QPushButton *button = new QPushButton("Clear",this);
tableau = new MonTableauWidget(this);
tableau->setRowCount(1);
tableau->setColumnCount(4) ;
QKeyEvent event(QEvent::KeyPress, Qt::Key_Down, Qt::NoModifier);QStringList list ; list << "Désignation" << "Qte" << "Prix/U" << "Total"; tableau->setHorizontalHeaderLabels(list); layoutPrincipale->addWidget(tableau); layoutPrincipale->addWidget(button); setLayout(layoutPrincipale); connect(tableau,SIGNAL(cellChanged(int,int)),this,SLOT(addrow(int,int))) ; connect(tableau,SIGNAL(keyPressEvent(QKeyEvent*)),this,SLOT(newRecod(QKeyEvent*))); connect(button,SIGNAL(clicked()),tableau,SLOT(clear()));}
Dialog::~Dialog()
{}
void Dialog::addrow(int row, int col)
{
if(col == 0)
tableau->insertRow(tableau->rowCount());
}
// her is the problem
void Dialog::newRecod(QKeyEvent *record)
{
QModelIndex index = tableau->currentIndex();
int row = index.column();
if(record->key() == Qt::Key_Down)
if(tableau->item(row,0)->text().isEmpty())
QMessageBox::information(this,"Empty Designation","Please Fill in the cell");
else
tableau->insertRow(tableau->rowCount());
}@

keyPressEvent is not a signal, I would advise you to read its "documentation":http://qt-project.org/doc/qt-4.8/qabstractitemview.html#keyPressEvent
From your previous posts, and just to be sure, do you expect me to validate your work ?
