Thinking about ReverseArrowCursor

[bluenlive]

hello.
Thanks as always for a great program.

As you know, in notepad2-mod, when you move the mouse cursor to a certain position, the left and right sides are reversed.
However, in current MS Windows, this feature does not work as expected when we adjust the DPI or increase the size of the mouse cursor.

I know @zufuliu has also given a lot of thought to this issue.

I created an additional mouse cursor file and included it in the resources of notepad2-mod to implement this feature.
It worked as expected, except for two programmatic issues.

1. We need to modify ScintillaWin.cxx
2. The IDC I defined in resource.h could not be read by ScintillaWin.cxx, so I had to enter the resource ID manually

Here's what we did
It's pretty straightforward.

1. Put the files ReverseArrow.cur, ReverseArrow_min.cur in the res folder
2. in Notepad2.rc, give these files an ID called IDC_REVERSEARROW
3. define IDC_REVERSEARROW in resource.h as 104
4. modify DisplayCursor() in ScintillaWin.cxx

void ScintillaWin::DisplayCursor(Window::Cursor c) noexcept {
	if (cursorMode != CursorShape::Normal) {
		c = static_cast<Window::Cursor>(cursorMode);
	}
	if (c == Window::Cursor::reverseArrow) {
		// This is the original code
		//::SetCursor(reverseArrowCursor.Load(dpi));
		::SetCursor(::LoadCursor(hInstance, MAKEINTRESOURCE(104)));
	} else {
		wMain.SetCursor(c);
	}
}

While this is neat, I don't think it's the right way to go.
Does anyone have any other ideas?

The cursor file can be downloaded from the link below.

So using external cursor file fixed issue #635?

Oh, yes.......... it is.
And I forgot that the issue wasn't closed... ;)

You can use 101 for IDC_REVERSEARROW.
Use ReverseArrow_min.cur has same quality as 244c226.
