Subject: bug#68374: min-width is not correctly treated by buffer-text-pixel-size
Date: Wed, 10 Jan 2024 17:22:53 -0500 [thread overview]
Message-ID: <EC5ECEDB-646A-4DAE-BD97-FB7F086C746D@gmail.com> (raw)
When the ‘display min-width property is used on characters in a buffer, window/buffer-text-pixel-size does not include this min-width padding in its calculation of the text's pixel width.
This can be seen by using a range of minimum character widths and noticing that the width is identical; see below. Other ‘display properties like space :width and space :align-to do seem to be correctly handled by pixel size calculations.
This is relevant because various elements on the mode-line use ‘display min-width, so performing pixel alignment on the mode-line text is impacted.
