Comment on Stack vs Heap, Pimpl, performance by yshurik

jstaniek: that’s possible of course, you can have some kind of pre-processing for compilation to have it in portable way. Not sure if the approach worths it, maybe for something heavy that requires a lot of tweaks. In this lab I just tried to make totally same class with d-pointer/d-array, but have full control of memory usage, and to show the danger for developers when heap is used implicitly.

Nice idea

The trick as BIC as using attributes inline, right?

BTW, I was wondering how to get automatic contant value of sizeof(Private) in a portable way. I am thinking about automated test running at build time e.g. by cmake in my case.

Comment on Undo in complex Qt projects by Scott Brown

Scott Brown — Mon, 23 Jan 2012 15:26:24 +0000

This is the closest I have ever seen to someone talking about Qt Undo/Redo in the context of a large application with a variety of data views, etc. The Qt docs for undo/redo explain the concept, but the example simply doesn’t scale. I feel the same about their examples for Model-View, which focus on tree and table views rather than a large application that will have custom forms, inhomogeneous and hierarchical data, etc. And this is coming from someone that thinks the Qt is one of the best documented developer APIs out there.

I was hoping that you would elaborate on the potential recursion issue and your ‘cover’ property? How/When does the ‘cover’ property get initialized? A brief state-style description of how ‘cover’ is protecting us from a recursion situation (and the harm that would create?) would be really appreciated.

Comment on SuperHybrids part 2, now Qt + PySide by strattonbrazil

Is it possible to use pyside for calling python from C++ so one doesn’t have to start the application from python?

Comment on Submiting a Qt App to Mac App Store by David

Actually – you can delete the last comment. The app was rejected because the file written to in ~/Library/Preferences/ didn’t match my bundle id. At least – when I changed it to that format it was accepted. Apple was not clear on this point.

Looks like the guidelines have changed since this blog was written.

I just had an app rejected because it wrote to this location: ~/Library/Preferences/
Doesn’t matter that it was wasn’t a trolltech file.

See location guidelines here: http://developer.apple.com/library/mac/#releasenotes/General/SubmittingToMacAppStore/_index.html#//apple_ref/doc/uid/TP40010572

Don’t know the solution yet … researching…

> Sounds to me like you can create and sign your Certificate yourself, no? Or are there Mac App Store specific requirements (which are non-public) which require you to have your Certificate signed by Apple, as you suggest?

Yeah, I guess they do this check to know that you paid money to them
