Subject: We are not forced to redraw the row each time the cursor is moved.
X-Git-Tag: 1.6.10~8658
X-Git-Url: https://git.lyx.org/gitweb/?a=commitdiff_plain;h=5440aad9286ae7905ec6b0c29248ca41aaa0a4bf;p=lyx.git

We are not forced to redraw the row each time the cursor is moved.

* TextMetrics.cpp: CursorOnRow() removed.
* TextMetrics::drawParagraph() do not check cursor position.
