Eirik Bakke updated NETBEANS-4166: ---------------------------------- Description: 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 Changing these from int to float will require various other methods and members to be updated as well. was: While fixing NETBEANS-346, I discovered several other editor painting coordinate calculations which are likely inaccurate due to rounding errors.
