The Application Programming Interface (API).

Creating user interface for a plugin (adding menu buttons etc.)

EQUINOX-3D uses the platform-independent GUI library, called EGUI.
This library is capable of creating menus, dialog boxes etc.
The most common GUI element you will need is probably a menu or ToolPanel button that activates a function in your plugin.

For example:

 XeAddPushButton("Tool->Transform", "Origin to ctr", '\0',
   NULL,  NULL, FALSE,
  "Move local origins of Models to the center.",
  _CB_OriginToCenter, (EPointer)0);

The above call will add a button to the "Transform" folder of the ToolPanel, labeled "Origin to ctr".
"Move Model's local origin to\nthe center of its geometries" is the tool-tip (bubble help) that will appear around the button if the user rests the pointer on the button for a few seconds. Note that the '\n' (new line) code is accepted in strings.

The function _OriginToCenter() will be called when the user activates this button.
_OriginToCenter() has to be defined like this:
 void _OriginToCenter(EguiItem PItem, EPointer PClientData,
                         EPointer PCallData)
 {
 .
 .
 }
The string, "Tool->Transform" is the so called location name.
These are the valid GUI location names:

Top (main) menubar
"Menu->File"

Vertical menubar
"Menu->Info"
"Menu->Display"
"Menu->Camera"
"Menu->Light"
"Menu->Create"
"Menu->Spline"
"Menu->Surface"
"Menu->Transform"
"Menu->Hierarchy"
"Menu->Geometry"
"Menu->Material"
"Menu->Clone"
"Menu->Delete"
"Menu->Effect"
"Menu->Render"
"Menu->Select"
"Menu->Select->Polygon"
"Menu->Skeleton"
"Menu->History"

ToolPanel
"Tool->Light"
"Tool->Create"
"Tool->Surface"
"Tool->Clone"
"Tool->Transform"
"Tool->Hierarchy"
"Tool->Geometry"
