How to paint a widget outside paintEvent()

[wesley]

QPaintEvent doesn't have any flags field or anything you could use to do that. You could try to subclass QPaintEvent and then use dynamic_cast, but that might not be reliable.

if i declare a class-wide flag named "bDrawAnimatedCaption",

void on_AnimationTimer_timeout()
{
    do some animation work here
    ... ...
 
    bDrawAnimatedCaption = true;
    update(currentIndex()); //it will trigger paintEvent to update current index
}
 
void paintEvent(QPaintEvent *event)
{
    if(bDrawAnimatedCaption)
    {
        paint animated cation here
         ... ...
        bDrawAnimatedCaption = false;
    }
    else
    {
        QListView:: paintEvent(event);
    }
}

void on_AnimationTimer_timeout()
{
    do some animation work here
    ... ...

    bDrawAnimatedCaption = true;
    update(currentIndex()); //it will trigger paintEvent to update current index
}

void paintEvent(QPaintEvent *event)
{
    if(bDrawAnimatedCaption)
    {
        paint animated cation here
         ... ...
        bDrawAnimatedCaption = false;
    }
    else
    {
        QListView:: paintEvent(event);
    }
}

To copy to clipboard, switch view to plain text mode 

Are these reliable ?

or is there another solution?
^_^, it just a test, but I hope it can work like this, because i can control the animation more easyer on MyListView side than delegate side.
thank you.
