QTableView, no selection rectangle

Hi,

Is it possible to hide the selection rectangle for the table view items when the item is highlighted and selected ?

I mean what I want is to select the cell and paint its background but I don't want to see the dotted selection rectangle around the cell.

try this

Code:

---

...
setSelectionMode(QAbstractItemView::NoSelection);
...

or you can implement your own delegate and do not draw selection.

Actually what I want is to select a row when I click on a cell, and I'm using setSelectionMode(QAbstractItemView::SingleSelectio n) and setSelectionBehavior(QAbstractItemView::SelectRows ).

What I don't want is the dotted rectangle displayed when I click on a cell. It can be easily seen when selection mode is set to `NoSelection`. It does not selects the cell, but the active cell is shown with this rectangle.

now it's clear. so, you need to implement your own delegate and don't draw dotten focus rect.

Code:

view->setFocusPolicy(Qt::NoFocus);

what about keyboard navigation in this case? it will not work.

What's the point of having focus if he wants to hide it? :)

that's true. :) but I think he wants to have keyboard navigation I think. :)

that will do the trick but there is a minor bug ( I guess this is not a feature :) ), when focus is deactivated, when a cell is double clicked for editing, after the editing, the focus rectangle becomes active again.

setting the item flags to un-editable mode fixes that problem.

is there a way to set the table as read-only so that none of the items are editable?

Yeah actually I may need keyboard navigation. But I guess I can implement keyboard inputs to change the selected rows, without using the focus.

do you think this is bet solution to implement navigation of treeView which is already works fine insted of creating custom delegate and write several lines of code? I don't thinks so.

can you describe which part I have to reimplement so that I can lose the focus rectangle?

the main reason why I want to do such things is that, I want to implement an outlook-like message list, and I think the best way is to use QTableWidget. do I proceed in the right direction or do you have any other suggestion ?

example

Code:

---

class MyDelegate: public QItemDelegate
{
	Q_OBJECT
public:
	virtual void drawFocus ( QPainter * /*painter*/, const QStyleOptionViewItem & /*option*/, const QRect & /*rect*/ ) const {}
};
...
	QTableWidget *table = new QTableWidget(10, 10);
	table->setItemDelegate(new MyDelegate());
	for (int row = 0; row < 10; ++row) {
		for (int col = 0; col < 10; ++col) {
			QTableWidgetItem *item = new QTableWidgetItem();
			table->setItem(row, col, item);
		}
	}
...

			table->setItem(row, col, item);
		}
	}
...

Thanks a lot Spirit, for not giving up on me :)
I finally got what I need.
