After downloading eclipse3.7, we found that the default font of this version is not Courier New, later, through eclipse-> Windows-> preferences-> General-> apperance-> colors and fonts-> basic-> text fonts settings, I found that this font did not exist, and then I found information online, you can directly modify the configuration.
First find \ plugins \ org. Eclipse. jface_3.7.0.I20110522-1430.jar In the eclipse installation directory (different eclipse versions, different file names, but are similar)
Then open it with rar, and then open \ org \ eclipse \ jface \ resource \ jfacefonts_windows7.properties in sequence (different systems modify different corresponding files, my name is win7)
Set
Org. Eclipse. jface. textfont.0 = Consolas-regular-10
Org. Eclipse. jface. textfont.1 = Courier New-regular-10
Modify
Org. Eclipse. jface. textfont.0 = Courier New-regular-10
Org. Eclipse. jface. textfont.1 = Consolas-regular-10
Save the modification. WinRAR will prompt whether to update the compressed file, select "yes", and restart eclipse.
