Hi All,
Bug: https://bugs.openjdk.java.net/browse/JDK-8191428
It is seen that with
8172025: HiDPI with non-integer scale factor - SPANs in HTML are
rendered overlapping each other
fix, the html text in button is rendered in different lines even though
it is specified as a one word.
This is because with getSpan() returning float value (say 29.9996)
FlowView.layoutRow() calculates "spanLeft" using getFlowSpan() method
which uses "int" calculation (so get 29]
whereas "chunkSpan" got from GlyphView#getTabbedPane (using
GlyphPainter1.getSpan) gets "float" value [ie 29.9996]
so this calculation (chunkSpan > spanLeft) is satisfied [ex, 29.996 >
29] and so it calls breakView() to break the text.
In the proposed fix, I have reverted the getSpan() value to return "int"
so as to prevent this regression.
This fix also does not cause any problem with 8172025 issue which
renders fine.

Another approach is to use "float" calculation for all "spans"
calculation but that will cause many changes, including changing
public/protected method signature
which I believe is risky at this point of time for jdk10, as it might
potentially cause more regressions.
Sneak peek of 2nd approach changes are: [work in progress]
