[SOLVED] QTableview with expandable rows

[mohsen]

Hi, I need to have rows with expandable icon (+) and child rows which have dedicated headers like below:

@Column1	Column2	Column3
-Row1
Child Column1	Child Column2	Child Column3
---------------	---------------	--------------
Child Row1	Child Row 2	Child Row3
-------------	------------------	--------------
+Row2		@

Any help would be appreciated!

did you look at "QTreeView":http://developer.qt.nokia.com/doc/qt-4.8/qtreeview.html

does QTreeView able to have dedicated columns for child rows?

Use QTreeView with a QTableModel; if you need more control, I'll suggest to design a custom delegate , maybe a simple composite widget like kget's:

Also interesting perhaps is "QTitanDataGrid":http://devmachines.com/products/qtitandatagrid-overview.html

@Soroush: Thanks for your suggestion. I was looking for a simple way but the custom delegate appears to be the only solution.

@Andre: Thank you Andre! I was already checked that but it's commercial. I'm looking for a free one.

I've found the solution. It's so easy and simple. We may do that using QTreeWidget.
@
// Row 1
QTreeWidgetItem *row1 = new QTreeWidgetItem(ui->treeWidget);
row1->setText(0, "Row 1"); //Column 1
row1->setText(1, "Data"); //Column 2

// Row 2
QTreeWidgetItem *row2 = new QTreeWidgetItem(ui->treeWidget);
row2->setText(0, "Row 2"); //Column 1

//Child row for Row1
QTreeWidgetItem *row1_child = new QTreeWidgetItem(row1);

//Custom widget for child row
QPushButton *pb = new QPushButton("Custom Child", ui->treeWidget );

//Set custom widget to the child row
ui->treeWidget->setItemWidget(row1_child, 0, pb);
row1_child->setFirstColumnSpanned(true);
