enable all Tooltips

[clive]

Is it possible to turn all tool tips on and off globally in an application?
If so how?

am not sure if it possible.
But you can try catching the tooltip event in QWidget::event using QEvent::ToolTip, and ignore the event.
hope this helps :)

Furthermore, installing an event filter (http://doc.trolltech.com/latest/qobject.html#eventFilter) on the application object gives you access to all events of the whole application. Notice also Qt::WA_AlwaysShowToolTips (http://doc.trolltech.com/latest/qt.html#WidgetAttribute-enum).

Thanks....

For future reference for others this is what I did.

I add this function to my app...


bool MainWin::eventFilter(QObject *obj, QEvent *event)
{
if(cbToolTips->isChecked() == true)
{
if (event->type() == QEvent::ToolTip)
{
return true;
}
else
{
return QMainWindow::eventFilter(obj, event);
}
}
else
{
return QMainWindow::eventFilter(obj, event);
}
}

Note I am using a CheckBox to determine if tool tips need to be disabled.

In the header file I add this..


protected:
bool eventFilter(QObject *obj, QEvent *ev);


Then I install the filter like this


qApp->installEventFilter(this);


I hope this helps others.
