Creating a Tooltip-like widget for mouse-hover of QListView items

Hello.

I have a QListView in which I have arranged the items of an item model in a grid (using the icons from each item's Qt::DecorationRole).

What I would like to do now is to create an effect whereby, when the user hovers the mouse over one of the items in this grid - after a given delay - a box containing information about the hovered item is displayed somewhere near the cursor.

The box can not be constrained by the size of the viewport.

The problem is that I am not very sure where to begin. As far as I understand delegates, they seem insufficient for achieving this. Regular tooltips even more so (since their content's layout is fairly fixed).

Would this be a matter of creating a QWidget-subclass (layed out in whatever way I need) with certain window flags somewhere in my QListView subclass after the firing of a timer after a hover has been detected?

Any ideas?

Thanks in advance.

Why is Qt::ToolTipRole not suitable?

I'm sure Qt::ToolTipRole is perfectly suitable.

I was wondering more about the mechanics of how to temporarily display such an 'overlay' above the window containing my view.

You simply return a QString containing the tooltip text. Qt will take care of displaying it.

You can have some control over the display style of the standard tool tip text using style sheets attached to QToolTip.
