Eclipse plug-ins. How to programmatically access to workspace preferences?

Question

In Eclipse, I need to access "Preferences > General > Appearance > Colors and Fonts" programmatically.

How can I do it?

Answer 1

此首选项页面定义当前主题颜色和字体注册表中的条目。

获取当前主题：

ITheme currentTheme = PlatformUI.getWorkbench().getThemeManager().getCurrentTheme();

获取注册表：

ColorRegistry colorRegistry = currentTheme.getColorRegistry();

FontRegistry fontRegistry = currentTheme.getFontRegistry();

使用org.eclipse.ui.themes colorDefinition或fontDefinition条目中定义的密钥访问各种颜色和字体。一些最常见的ID在JFaceResources：

中定义

Color color = colorRegistry.get("color id");

Font dialogFont = colorRegistry.get(JFaceResources.DIALOG_FONT);

您还可以获得一组已定义的键：

Set<String> fontIdKeys = fontRegistry.getKeySet();

您可以从FontData获取字体的字体名称：

FontData [] fontData = dialogFont.getFontData();

String fontName = fontData[0].getName();
