2022-07-27Fix typo.John Ankarström
2022-07-27Fix status bar help message.John Ankarström
The string arrays are static.
2022-07-27Change WM_MENUSELECT handling.John Ankarström
This has two benefits: 1. The for loop is avoided. 2. It is shorter. The drawback is that it is a bit opaque. The order of the array elements still matter, but now it is coupled to what is declared in resource.h, a completely separate file. This makes it harder to change resource.h.

2022-07-26Use 's' instead of 'str' for as prefix for managed strings.John Ankarström
2022-07-26Remove ANSI compatibility.John Ankarström
Even though it is a fun challange in many ways, I think that, realistically, it is probably not worth the complexity. The Prolog backend isn't ANSI-compatible either.
2022-07-26Improve Win32Error, library handling code.John Ankarström
2022-07-25Move menu command processing to separate functions.John Ankarström
2022-07-25Reorganize resource IDs, message handling.John Ankarström
The resource IDs have been changed such that * the first (least significant) half byte represents the "group", * the second half byte represents the "subgroup", and * the third and fourth half bytes uniquely identify the resource within the group. Combined with the use of a few helper macros, this makes the message handling code a lot simpler.

2022-07-24Improve window layout.John Ankarström
This reverts much of 97f0a27. 1. It turns out not to be a good idea to resize the list view columns based on the list view window's own rectangle, as it will change depending on whether a scrollbar is visible. The problem is that resizing the columns may add a horizontal scrollbar -- which in turn may add a vertical scrollbar. 2. The WS_EX_CLIENTEDGE style does not look very good in "modern" (non-classic) themes. In 97f0a27, I tried solving this by extending the dimensions of the child windows such that their edges were hidden. However, this type of overlapping causes problems with the status bar. My new solution is to instead *reduce* the child windows' dimensions. This achieves a visual impression similar to the thicker (more well-designed) edges of the "classically themed" list view control. To make it look even better, the main window background is changed from COLOR_WINDOWFRAME (white) to COLOR_WINDOW (light gray).

2022-07-23Improve UpdateLayout and ResizeColumns.John Ankarström
This incidentally removes the need for the variable template introduced by 21e96c6. I'm sure it will be needed at some point, though.
2022-07-22Cache GetSystemMetrics values with variable template.John Ankarström
The variable template could be generalized like this: template <auto F, auto... A> const auto cache = F(A...); and instantiated like: cache<GetSystemMetrics, SM_CXVSCROLL> It would still be limited to constant function arguments, which usually isn't a problem for GetSystemMetrics, but might be for other functions.
2022-07-22Set owner of termination message box.John Ankarström
If the main window exists, it is probably a good idea for the message box to be owned by it. Otherwise, the user may continue to interact with the main window. Of course, that could sometimes be a benefit, but it SEEMS a bit unsafe... I might change this in the future.
2022-07-21Simplify OnTerminate.John Ankarström
No, not "awful", AWFUN! Speaking of AWFUN, here is an alternative implementation of it: #define AWFUN(t, f) cond_fun<t, f##A, f##W> template <typename T, auto F, auto G> std::enable_if_t<std::is_same_v<T, char>, decltype(F)> cond_fun = F; template <auto F, auto G> auto cond_fun<wchar_t, F, G> = G; This implementation uses a variable template instead of a function template, but I decided against it, as (at least I think) it would instantiate useless variables that merely point to pre-existing API functions. Like, auto cond_fun__wchar_t__blablabla = MessageBoxW; auto cond_fun__char__blablabla = MessageBoxA; which is quite useless. Better to just have a constexpr function, which the compiler may inline, return the real function pointer.
2022-07-20Improve fatal error messages.John Ankarström
As the message box has no owner (because the main window may not be initialized yet), it may be unclear which application is being terminated.

2022-07-20Fix timer.John Ankarström
2022-07-20Fix bug in and rename throw_nil, warn_nil.John Ankarström
In warn_nil, the return value was undefined on exception -- I think. While informative, the names throw_nil and warn_nil don't work very well in conditionals: if (warn_nil<f>(...)) g(); sounds like g should be called if f returns nil and a warning is issued. But it is actually the other way around; g is called if f is successful. if (prefer<f>(...)) g(); sounds less like that.
2022-07-19Check Windows API calls for errors more consistently.John Ankarström
Some of the checks are likely redundant, but the Windows API documentation rarely makes it clear WHICH errors may be returned (and under which circumstances) rather than simply WHETHER errors may be returned (under any circumstances, including those that do not apply in the given case).

2022-07-18Improve Library::GetProcAddress.John Ankarström
It isn't really more safe, but it removes the need for a confusing function pointer cast, which is easy to get wrong. As far as the compiler is concerned, the result is literally the same, but it does force the caller to (indirectly, via the template parameter) cast the return value, which may be a good thing.

2022-07-18Fix 26bc4109.John Ankarström
Apparently, = {0} does not zero a structure in C++.
2022-07-18Ensure that CBT hook is set and unset correctly.John Ankarström
2022-07-17Prefer f() over f(void).John Ankarström
f(void) is a C-ism that is valid but unnecessary in C++.
2022-07-17Make ListView hWnd public.John Ankarström
A getter offers encapsulation, but it is also less transparent in a sense. Thinking of ListView as a struct, it is natural to expose hWnd as a public member variable.
2022-07-17Update type names and variable prefixes.John Ankarström
2022-07-17Add const to pointers, update spacing.John Ankarström
It seems that "right-spaced" pointers are more widely used among C++ programmers.
2022-07-17Add const to places.John Ankarström
Note that I did NOT add const to non-pointer/non-reference arguments in function declarations (without a following definition), as they do not mean anything there.
2022-07-16Formatting.John Ankarström
2022-07-16Rewrite TszFromSz as TsmFromSz.John Ankarström
I.e. using std::basic_string<TCHAR> instead of TCHAR *. This removes all unmanaged frees.
2022-07-16Add m_hWndParent to ListView.John Ankarström
This avoids g_hWnd.
2022-07-15Split defs.h into separate header files.John Ankarström
This is feasible now that the makedeps script exists to automatically manage build dependencies (see 6034fe2, d00f8b3).
