			abalajiAuthorUnsubmitted Done Well, I didn't intend to make this stupid change haha. I wrote this file from scratch and the lines happened to line up in the diff. And I think `QObject ` is correct since `QuickEditor` is created by `X11ImageGrabber`, which is a `QObject` abalaji:* Well, I didn't intend to make this stupid change haha.

			alexeyminUnsubmitted Done Some constants are initialized in .cpp-file, some here in header, why so inconsistent? And this line is also using constexpr, while others don't alexeymin: Some constants are initialized in .cpp-file, some here in header, why so inconsistent? And…
			abalajiAuthorUnsubmitted Done So, I'm trying to keep all constants in the .cpp file since they are implementation details. But, since `bottomHelpText` is an array, and the length of an array is necessary (variable-length arrays not allowed in C++), I'm forced to leave this constant in the header file. `constexpr` is not really needed here tho, so I can make it just `const`. abalaji: So, I'm trying to keep all constants in the .cpp file since they are implementation details.
