Compiler environment in WingEditor can be used in two ways,

To compile a single file, the default compiling option is empty, the default classpath is the current system classpath, and the default compiler command is to use the compiler (javac) coming with JDK. Users can change these paramteres by go to the Build menu, and select Setting.

To compile a project, users have to create a project first. For details on project, please see \How to Create a Project\. Then, set the project as the current project (go to Build menu, and select Setting).

Users can select to either compile all sources in the project, or compile incrementally. The Compile button is for compiling incrementally. To compile all sources in the project, go to Build menu, and select Compile All Sources.

If any errors are found during compiling, WingEditor will bring up an Error-Browser window, users can click the line with both source file name and line number to direct WingEditor bring up a window showing the file and mark the line number with color.,
