2018-08-27The final game: mark everything final.Tom Sepez
Then revert the ones that break compilation. Fix one IWYU noticed during presubmit. Change-Id: I881a8a72818e55dbc4816247e35ff5e3015194e7 Reviewed-on: https://pdfium-review.googlesource.com/41470 Reviewed-by: Lei Zhang <thestig@chromium.org> Commit-Queue: Tom Sepez <tsepez@chromium.org>
2018-06-20Re-work some more c_str() usage.Tom Sepez
Many of these are converting ByteString => c_str => ByteStringView, since the ByteStringView ctor is implicit. This is unfortunate, since that involves a strlen() which the ByteString already knows if we use AsStringView() instead. This changed one test result where we can now return the string "\0" instead of "" -- since strlen no longer eats the NUL. This seems consistent, say, with String.fromCharCode().

2018-06-01Remove initialization of wchar_t chRyan Harrison
This value is overwritten at the beginning of the following while loop, so the initialized value is never used and the method called is const, so should be side effect free.

2018-05-23[xfa] Skip text length check for empty text fieldschromium/3439Dan Sinclair
This CL sets the text edit engine to skip the length check when doing an insert if the engine is currently empty.

2018-04-24Fix caret moving to next line on click in multiline XFA edit.Henrique Nakashima
On a mouse click after the end of a line (except for the last line) in an XFA text edit, the caret was moved to the beginning of the next line, as the position after the space was actually in the next line. This CL changes the behavior so that the caret is positioned before the space in this case. Note it's possible to click directly to that position by clicking on the beginning of the next line.
