[jira] [Updated] (NETBEANS-4166) Review likely inaccurate int-based
character width calculations in editor UI
[ https://issues.apache.org/jira/browse/NETBEANS-4166?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Eirik Bakke updated NETBEANS-4166:
----------------------------------
Labels: HiDPI (was: )
> 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 & Printing
> Affects Versions: 11.3
> Environment: Windows and MacOS with HiDPI/retina displays, Java 9 and above
> Reporter: Eirik Bakke
> Priority: Minor
> Labels: HiDPI
>
> 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.
