------------------------------------
Summary: Output tab name truncated
Key: NETBEANS-2649
URL: https://issues.apache.org/jira/browse/NETBEANS-2649
Project: NetBeans
Issue Type: Bug
Components: platform - Window System
Affects Versions: 11.0, 8.2
Environment: Windows 10
Reporter: Rangi Keen
Attachments: Truncated Output Tab.png
When running NetBeans with JDK 11 (specifically AdoptOpenJDK 11.0.3+7) on
Windows 10, the Output tab name is truncated and appears as "Outp..." rather
than "Output".
The problem appears to be related to text antialiasing not being used in the
offscreen graphics while it is used when actually rendering the tab contents.
The widths of some characters, notably the wider capital letters such as "O",
differ when "LCD HRGB antialiasing" (and perhaps others) is used.
Adding the following to {{BasicScrollingTabDisplayerUI.getOffscreenGraphics()}}
appears to resolve the issue:
{code:java}
public static Graphics2D getOffscreenGraphics() {
...
Graphics2D graphics = (Graphics2D) result.getGraphics();
graphics.setRenderingHint(RenderingHints.KEY_TEXT_ANTIALIASING,
UIManager.getDefaults().get(RenderingHints.KEY_TEXT_ANTIALIASING));
return graphics;
}{code}
