Custom qtreeview

swarsi

I need some guidance here on how to possibly implement the following custom
qtreeview.

Suppose I have QTreeView with say 4 columns

1.I want to be able to say click on an item in the first column and allow it
to be edited to another name EXCEPT if is A,B,E or F (any top level item) but any other item
such as C,D,G,H, etc. can be edited to a new name. Additionally, I want to be able to click
on a checkbox and change its setting.

How can I get the pointer back to my derived QTreeViewItem so that i can then
apply them to the underlying data?

Thanks for any help.

If you can use QTreeWidget the following should work. QTreeWidget is a subclass of QTreeView so everything the widget can, the view also is able to but maybe with a bit more programming effort.

You can use
@
item = new QTreeWidgetItem();
tree->addItem(item);
@

to add a new item to the tree. By giving a parent you can build your hierarchy. After that you can set your own widget for the item with
@

tree->setItemWidget(item, 0, new MyWidget());
@

I am not sure which methods you can use with the QTreeView but as I wrote before you can write all of them yourself if necessary.

You can get you widget back with

@
QList<QTreeWidgetItem *> selected = tree->selectedItems(); //or if you want to use the mouse pos
tree->itemAt(x, y);
@

EDIT
You use the flags to make the items editable or whatever:

@
item->setFlags(Qt::ItemIsSelectable | Qt::ItemIsEnabled);
@

Be aware that for example if you parent item is not enabled you cannot select the child for example.
