installFilterEvent for all widgets

[wysota]

The tooltip solution should work out of the box for all children that don't have their own tooltips. If you prefer the event filter solution, you have to enable mouse tracking for all widgets.

QWidget::setMouseTracking

The same way you installed event filters to all widgets.

I wouldn't advise that really I wouldnt' advise doing what you are doing at all. I'd probably reimplement QCoreApplication::event() and do some smart event manipulations there to achieve the effect you want in a simmilar manner to the tool tip system already present in the event loop.

Thank you... i decided to use

QList<QWidget*> widgets = qFindChildren<QWidget*>(this);
	foreach(QWidget *widget, widgets)
		widget->installEventFilter(this);

QList<QWidget*> widgets = qFindChildren<QWidget*>(this);
	foreach(QWidget *widget, widgets)
		widget->installEventFilter(this);

As you wish. Just be aware that some widgets' functionality (especially ones that are not implemented correctly) might get broken because of the use of mouse tracking.
