Listing line number of results in `find` and `ls`

Question

When using a QToolButton and the setDefaultAction(myAction) method, it will get the default actions properties

Reference:

If a tool button has a default action, the action defines the button's properties like text, icon, tool tip, etc.

So I try to overwrite the icon, calling setIcon on the QToolButton.

myAction.setIcon(...);
myToolButton->setDefaultAction(myAction);
myToolButton->setIcon(...);

But it myToolButton still has the Icon of myAction.

Is there a way to hold the default action but overwrite it's icon, only for the QToolButton, not for the action itself? In otherwords: How can the QToolButtons have different properties than its default action?

Solution 1

You can use the following command:

ls | nl

Solution 2

"cat -n" will add line numbers. E.g.: ls | cat -n

Overwriting icon using setIcon perfectly works, at least in Qt 5.2. What is your Qt version?

eh, same solution, but somewhat different problem

Not if you see the problem for what it is: "Run some command and get line numbers in output"

[Admin]

but how would i go about finding that thread given my question, ie how did you find it?

[Admin]

Googled line number output site:unix.stackexchange.com (it was the last result on the first page.) The Stack Exchange site search is notoriously bad, Googling with a site restriction often yields better results.

[Admin]

eh ok, i'll accept that

The reference docs you linked were for Qt 4.8, so I checked the source for 4.8. It's got the same use of setIcon(action->icon()). Could you post a more complete code example? I've tested using setDefaultAction then setIcon, and it's working for me. I'll post an example if you'd like to take a look.

your code works for me. However my code doesn't and I don't understand why. Anyhow, it seems that I have another problem here.

Thx. Can't upvote but what I'm looking for.

what i'm looking for, thx. probably could find this but my google query was awkward, i think.
