Simple Table View

rudag

I'm translating a little app that I made in PHP-Gtk to Qt. I was going well till I had to do what in Gtk is a GtkTreeView, but in Qt I guess it's a QTableView or a QTableWidget, I don't know which one to use. Basically it has 3 columns (Accounts, Password, Group Id) and must have the option to sort the items asc/desc. Here is a pic of my app:

!http://img04.imgland.net/aB23Ojk2mE.jpg(pic)!

If you double-click any item, the entries below will be filled according to the item you cliked.
If you click Prev/Next buttons, it will clear the list and add the new items.

I'm really lost because:

I dont know what is better to my case: QTableView or QTableWidget
I couldn't test any of both, since I didn't find any simple example to newbies

So... could someone show me how to do a simple table like in the pic? All the examples I found were difficult.

Thanks

PS: (I just want the table, forget the other widgets)

Hi,

you have two choices:

QTableView or "QTableWidget":http://doc.qt.nokia.com/4.7/qtablewidget.html , as you already suggested.

The main difference is: QTableWidget is derived from QTableView.

For QTableView, you have to create your own "model":http://doc.qt.nokia.com/4.7/model-view-programming.html where as QTableWidget already contains a QStandardItemModel

QTableWidget (from programmers point of view) is just a widget containg items, which you add "QTableWidgetItem":http://doc.qt.nokia.com/4.7/qtablewidgetitem.html

That doesn't seem to be a QTableView, but a QTreeView with an undecorated root.

You can use "QDataWidgetMapper":http://doc.trolltech.com/4.7-snapshot/qdatawidgetmapper.html to map the data to the dialog elements.

Peppe is right, QTreeView/Widget is the way to go. QTableView would have a "header" to the left too.

For some simple data you can got with the widget, create the QTreeWidgetItems. You have to enable sorting in the header

@
treeWidget- >setSortingEnabled(true);
@

Or check the respective property in Qt Designer/Qt Creator's designer component.

Or you hide the header on the left, of course... :-)

Why use a QTreeWidget, then a QTableWidget is enough? Just hide the headers you don't need.
If you don't like the grid lines, hide them. Then you've got it.

If you don't want a tree, you shouldn't use one, right?

Because of the way of how it's rendered. A table-like view without Excel-like "cells" is done using a tree view, that's it :)

Ok, thanks for the help. I'm using QTreeWidget now and I implemented it just to see how it works:

@QStandardItemModel *model = new QStandardItemModel;
QStandardItem *parentItem = model->invisibleRootItem();
for (int i = 0; i < 4; ++i) {
QStandardItem *item = new QStandardItem(QString("item %0").arg(i));
parentItem->appendRow(item);
}

QTreeView *view = new QTreeView;
view->setModel(model);
view->show();
layout->addWidget(view);@

My question now is:
How do I add the headers (Account, Password, ...) like in my pic?

giesbert

There is a "QStandardItemModel::setHorizontalHeaderLabels":http://doc.qt.nokia.com/latest/qstandarditemmodel.html#setHorizontalHeaderLabels

Just read the docs, it's stated there :-)

by the way: if you want to access the model later on, store the pointer in a member variable :-))
