EyeRad

Description

A RAD tool for create JSon files to be parsed with eyeJFP.

It will function like glade tools in xml mode. I will start develop with the eyeJFP, and the Rad environment will be written in it.

Characteristics

• Different from glade files, all forms will have their JPF file.
• Will be SDI in one-form, editing one Window/file per time.

Questions

• Will the JFP file be human readable? YES!
• The pseudo-widgets in develop area form will be actual instances of widgets (like Delphi) or fake ones (like Glade)? Fake Ones
• Will have an interface to user install new Widgets interface like Delphi, or this support must be inside eyeRAD? ??? Yet
