What is the meaning of どうの?


Context: a former swordsman takes his daughter to attend kendo lessons. She
doesn't seem happy, so he reminds her that she decided herself to go, at which
che replies:

> んだよ！とーさんがさんざん剣が **どうの** って話ばっかするからだろ！！

What is the meaning of どうの? I found an example on Kenkyusha dictionary
suggesting it can be used in lists:

> 色が **どうの** デザインが **どうの** と彼女は文句ばかりつけている.
>
> She's forever complaining; if it isn't the color, it's the design or
> something else.

Is this the way it was used in my sentence? Thank you for your help!




It's the same as どうこう or どうのこうの explained in [this
question](https://japanese.stackexchange.com/q/61932/5010). It replaces a
(subjectively) unimportant part of the sentence like "blah blah". In this
case, the father has told her a long story about 剣, but she is thinking what
he said was unimportant to her.
