Disable selection for vertical/horizontal header - QTableWidget

[hbatalha]

Basically I don't want this:

or this:

I have tried these but they don't work:

ui->table->verticalHeader()->setSelectionMode(QAbstractItemView::NoSelection);
ui->table->horizontalHeader()->setSelectionMode(QAbstractItemView::NoSelection);

@hbatalha
Does QHeaderView::setHighlightSections(false) do what you want?
[EDIT: Maybe not, since it says "By default, this property is false.", yet it does sound to me like it should be this?]

[hbatalha]

@JonB it doesn't do it.

[hbatalha]

@JonB However... QHeaderView::setSectionsClickable(false)

ui->table->horizontalHeader()->setSectionsClickable(false);

Even thought it is not made for that purpose but it does solve this particular problem of mine.

Hi
It does disable it showing it on the headers.

but you want to disable user can click on it to select the row?

update:
well yeah setSectionsClickable should do it :)

No, I just wanted the headers not to get highlighted when the user hover the mouse.

@hbatalha

ok but even if setSectionsClickable(false); does kill this ability for the user, its ok solution ?

Not quite, for example for the vertical header it kills its ability to get selected when its row is selected.

Hi
I tried to grab the hover event

class test : public QHeaderView
{
    Q_OBJECT
public:
    explicit test(Qt::Orientation orientation, QWidget *parent = nullptr ) : QHeaderView(orientation, parent) {}
protected:
    bool event(QEvent *e) override
    {
        if ( e->type() == QEvent::HoverEnter ) return true;

        return QHeaderView::event(e);
    }

};

but that broke selection too.
so I didn't find a way to get rid of that coloring as it seems mostly to go on inside the d-> private section.

@mrjj I tried to grab hover through stylesheet but didn't work.

I guess selection is a small price to pay to get it done. At least until I find a better way.

[mrjj]

@hbatalha

Yeah, I guess so too. at least until a better way comes as the things i tried would then
break selection and no better than setSectionsClickable

[Christian Ehrlicher]

For Qt6 you can override QHeaderView::initStyleOptionForIndex().

[hbatalha]

@Christian-Ehrlicher could you provide a minimal working example?

[Christian Ehrlicher]

I currently see that setHighlightSections() should also work.

could you provide a minimal working example?

call the base class impl and then modify QStyleOptionHeader::state the way you want.
