How to get the return value? Attach my code. My intention: Want to check the QListWidget and if it's empty, a message Box popup will raise and ask the option from the user. Problem: At the stage of beginning itself, a Message box popup will display, (I don't want it at the beginning stage), If the QListwidget is empty then the MessageBox popup will display as desired, and if we select "Yes" or " No" Button, Nothing will return/print in the first file. How to resolve?

I have a vector of fish weight. I have written a function to check on the weight of the fish in the vector. If the weight is above 20, then update y (i.e., fish count) and z (i.e., fish total lbs). Below is the code:

Unity2D How to make game object to face opposite from the position of another game object?

The method plant() takes a String and a 2D array of String[][] as its inputs. The strings within the array should not be replaced by the inputted word.

Let's assume I had the following table:

I want to apply a filter so that I only see the rows that contain "cat" among the comma separated "tags" in Animals column. The regular filters, of course, don't separate the possible values but instead the filter is populated with the whole string: "dog", "dog, cat", "cat, fish, bird", etc.

Is there a way to get the filter to populate with the individual values "dog", "cat", "fish", etc.?

Alternatively, would you suggest a different table layout to achieve a similar solution, still using the manual filters? One that does not require one column per possible animal type, with boolean value.

Finally, if no solution is possible, of course there is always the option to do it with formulas, something like adding a separate cell whose input is searched in the Animals column and the corresponding entries are shown/hidden, but that is not what I am aiming for.

Denizens of stack overflow, I call upon your help and grand wisdom.

Problem: driver print is printing pretty much all that I need it to, but the first row also prints the entirety of the information as well in one long line. I've noticed the format doesn't stay for copy/pasting my console putput so I'll attempt to describe it. It prints out, neatly enough, a formatted table with the info I need. It's just that the top row duplicates the info as well. It appears to be the exact same print, just with no new lines

I have this shopping cart application. All is done and now I'm working on the toString formatting for the receipt looking printout in console. As this encompasses 7 or so different classes I won't post all of the code, but just the cart, driver, and parent class as it's my best guess that's where the problem is originating. If more is needed please let me know and I can post what I have.

I'm making a game discord bot that has different channels as different "areas," but I want the same command to do different things depending on what channel it was used in.
