The NewLook Fields Editor is a replacement for the standard Delphi Fields Editor (that appears when you double click a dataset component like TTable). It provides many additional features and is available with full source code. It works with 3rd party datasets as well as the standard ones.
Every Delphi developer who writes database applications should have this package as it allows you to:
The self-extracting exe installs quickly and painlessly into Delphi 3 and uninstalls using Control Panel, Add/Remove Programs.
You can still use the standard Delphi Fields Editor as well (by right clicking a dataset and selecting from the menu). So there are no disadvantages to installing it in your existing Delphi 3 setup.
A fully functional freeware version is available at http://www.newlook.co.nz, no time limit, no nags. Use it to speed up your database development! This version is limited to registering four new TField derived classes. That won't stop you using it to save lots of time.
