How do I add a font from window to eclipse?

I didn't notice that the fonts in window were not found in eclipse, and then I didn't know because some of the fonts in the window were set to hide so I couldn't find them.

Later on the Internet to find information found some solutions, some bloggers say this:

To change the plugins inside of Eclipse Org.eclipse.jface_3.7.0.v20110928-1505.jar open it and go into the/org/eclipse/jface/resources directory, And then find xxxxwindows7.properties in this jar package inside change things, I looked after also to try the results are not used, and more trouble!

It was later discovered that there was a hint:

Then I went in and looked at it, the original window automatically hides the font by default, so eclipse is not found by default and cannot be found in other programs!

Finally solved the problem, but also hope to have some help ~ OH
