Keyboard Arrow Navigation For Media Player

DzCode

Hi all,

I have 3 mediaplayer and 3 videowidgets in 3 different frames.

They are split with QSplitter in a main frame, and all 3 are controlled with the same time slider.

I have buttons for moving forwards/backwards. Now, I want to put a QAction for moving forwards/backwards. However, I coulnot catch any action. Also, I cannot catch key press event inside qwidgets.

How can I put keyboard navigation for my videos?

And I (and most probably others) cannot know why. You will need to show what you are doing.

"Also, I cannot catch key press event inside qwidgets" - same here and also make sure the widgets have focus.

@jsulm can I do it without giving them a focus?

Because, there are so much different widgets in the application.

Do it in the container widget then

@jsulm Actually I tried to add the qactions into mainwindow too to test but they are not trigger. I will try the keypressevent of it.

Edit: I tried but nothing works,

Child widgets negates it

@DzCode I think only eventfilter gives a response for that. I need to catch the watched object

Hi,

As @jsulm wrote, without any code we can't even guess what might be going wrong.

Your problem can be confirmed. Only these arrow keys do not triggger key event to
protected:
void keyPressEvent(QKeyEvent *e) override;

But check this out.

At first, thank you all.

I solved my problem.

Since I cannot share the code, I will explain what I did.

I gave object names to my videowidget and any related widget related with videos (buttons, slider, etc.)

In the eventfilter, I am filtering KeyPress and object name of the watched objects. If it suits my criteria, it will handles the arrow key navigation, otherwise upper class'es eventfilter is called.
