If it is relevant to add height for a header for a given list view, it
is better to override Height and do it there.
|
|
In case it is not supported. If I am not mistaken, SWI-Prolog supports
Windows 2000, so there is no reason why Episode Browser shouldn't.
|
|
Next step is to allow a double click to reset the split to be
automatically resized.

I don't hate Hungarian notation. It has some very nice qualities. But
it also adds a lot of typing.
That said, not using it feels a bit... unsafe. I might go back on this
decision. We'll see.
|
|
This makes it much more ergonomic and less error-prone to look up list
view items.
|
|
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.

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).

This incidentally removes the need for the variable
template introduced by 21e96c6. I'm sure it will be
needed at some point, though.

This improves upon 79d4fa6.
Actually, ANSI compatibility may be desirable, as recent work has been
done to make the A versions of Windows API functions work with UTF-8.

It's not very useful, but it's a fun exercise.
|

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.
|
|
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).

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.
|
|
|
|
This is obviously a lot less obtuse.
|
|
It seems that "right-spaced" pointers are more widely used among C++
programmers.
|
|
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.

This avoids g_hWnd.
|
|
This is feasible now that the makedeps script exists to automatically
manage build dependencies (see 6034fe2, d00f8b3).

On WM_DESTROY, the "this" property was removed before it could be
retrieved and dereferenced, making it impossible for WM_DESTROY
messages to be passed to the WndProc method.
|
|
Height(DLVSIKEY) was incorrect. The argument to Height is supposed to
be a boolean value, in this case false. It happened to work because
DLVSIKEY is 0 (because Key is the 0th column in the data list view).
|
|
The rules for what messages are sent at window creation -- and in
which order -- are neither intuitive or clear. WM_CREATE can NOT be
relied upon to initialize global state required by handlers of other
messages (such as WM_GETMINMAXINFO, which seems to be sent before
WM_CREATE).
Thus, the better solution is to initialize everything using a CBT hook
before the window procedure is even run. Because CBTProc creates
(child): windows of its own, though, one must be careful to only run
the initialization once, which is done by checking g_hWnd.

I already hit upon some object-oriented programming patterns in
*listview.c, so I felt that it would be natural to use this as an
opportunity to learn C++.
