Design view of Eclipse windowbuilder pugin on Windows 8.1 x64 prompts “Unknown GUI toolkit”
问题 I was using Eclipse Kepler Release 1 x64, wiht Java 7 x64 on Windows 4 pro x64 and I had no problems with Eclipse WindowBuilder plugin. But since I upgraded to Windows 8.1 pro x64, WindowBuilder has stopped working. First the follwoing button is freezed and does not respond to user clicks. And if in project explorer I go to some java file that I have already created with WindowBuilder plugin in windows 7 x64, right click on it and choose: Open with > WindowBuilder Editor , source code opens
