CSS won't work after intallEventFilter()

[MorrisLiang]

This is how it looks like,if I comment out the code:

ui.myText->installEventFilter(this);

ui.myText->installEventFilter(this);

To copy to clipboard, switch view to plain text mode 

This is how it looks like,if I install the event filter:


and the implenmentation of evetFilter is just:

bool MyWindow::eventFilter(QObject* target,QEvent* event){return true;}

bool MyWindow::eventFilter(QObject* target,QEvent* event){return true;}

To copy to clipboard, switch view to plain text mode 

It's not just QTextEdit,I also test the other QWidget.All behaves the same:if I install eventfilter,then it's stylesheet is gone.

I apply the style sheet by calling:

QFile stylesheet("myCSS.css");
stylesheet.open(QFile::ReadOnly);
qApp->setStyleSheet(stylesheet.readAll());
stylesheet.close();

QFile stylesheet("myCSS.css");
stylesheet.open(QFile::ReadOnly);
qApp->setStyleSheet(stylesheet.readAll());
stylesheet.close();

To copy to clipboard, switch view to plain text mode 

And I also set the stylesheet directly in the qt desiner,instead loading external file.
The problem still happens.

So,anyone has come cross this weird thing?Any solution?

So your blocking all events, but expecting the widget to behave as normal?

Now if you return false, you will not be filtering any events, so your CSS should work as designed.

Oh,my....I make a mistake....I thought "return false" means to filter out the event...
Thanks~
