Re: IDE: Accessing main settings outside of ScIDE::Main class

OK, here's a (potentially...?) more specific question that maybe someone can answer.

In MainWindow::restoreWindowState(), I tried deferring the restoreDetachedState() calls in a QTimer. But the behavior is different: saved state is ignored.

The same code retrieves the docklets' detached settings in both restoreWindowState() and the deferred function, but:

- Settings object memory address: Same in both places
- detachedData memory address: Different in the two places

MainWindow::restoreWindowState settings address = 0xbf8ad0 (passed as an argument from main())
detachedData address = 0x7ffdad2f9590

MainWindow::restoreDocksDetachedStates settings address = 0xbf8ad0 (Main::instance()->settings())
detachedData address = 0x7ffdad2f9530  <<-- wait, what, 0x60 lower?

So we have the same settings object, accessed by the same series of (I assume) deterministic operations (and presumably read-only operations), but the result is not the same. That means the deferred operations are not finding the correct saved state.

I can think of two explanations:

- something modifies the settings in between the two accesses (but, in my last test, I'm deferring by 0 ms...);
- or, there's something special about doing it from the argument-passed pointer rather than getting it from the instance.

Any insight into this?

(Well, I realize I'm talking to myself here... and I'm just about out of holiday time, so probably this will get dropped for another few months...)
