[jira] [Created] (NETBEANS-4166) Review likely inaccurate int-based character width calculations in editor UI

Eirik Bakke created NETBEANS-4166:
-------------------------------------

             Summary: Review likely inaccurate int-based character width calculations in editor UI
                 Key: NETBEANS-4166
                 URL: https://issues.apache.org/jira/browse/NETBEANS-4166
             Project: NetBeans
          Issue Type: Bug
          Components: editor - Painting &amp; Printing
    Affects Versions: 11.3
         Environment: Windows and MacOS with HiDPI/retina displays, Java 9 and above
            Reporter: Eirik Bakke


While fixing NETBEANS-346, I discovered several other editor painting coordinate calculations which are likely inaccurate due to rounding errors. Fixing these will be a bit of work, though, and it may be preferable to wait until specific bugs are identified before doing so, so that the changes can be verified to have had the desired effect.

The following members should likely be changed from an int to a float, and initialized from font metrics to full precision:
* org.netbeans.editor.EditorUI.defaultSpaceWidth
* org.netbeans.modules.editor.lib.drawing.DrawEngine.spaceWidth, defaultSpaceWidth, and possibly fragmentWidth
* org.netbeans.modules.editor.lib.drawing.DrawGraphics.defaultSpaceWidth

These changes will propagate to related APIs.
