PA_GetPluginProperties

version 2003

PA_GetPluginProperties (params; props)

Parameter	Type		Description
params	PA_PluginParameters		Parameters received in PluginMain
props	PA_PluginProperties*		Pointer the the area properties

The routine PA_GetPluginProperties returns the area settings in the PA_PluginProperties pointed to by props.

params is the PA_PluginParameters the plug-in received in its PluginMain routine.

props points to a structure of type PA_PluginProperties. This structure holds various information concerning the area: the font, size, face, color set by the user in the Design environment, drag and drop availability, and information while the area is printed.

This routine can be called only at initialization, when PA_GetAreaEvent returns eAE_Init or eAE_DesignUpdate. Otherwise, PA_GetLastError() returns eER_BadEventCall. If the plug-in needs to use the properties at any other time (MouseDown, update) it must duplicate the properties in a private structure.

This structure is defined in the "PublicTypes.h" header file as:

typedef struct PA_PluginProperties
{
   short   fVersion;
   short   fFontID;   // Macintosh font ID
   short   fJustification;
   char   fFontSize;
   char   fFontFace;
   long   fForeColor;
   long   fBackColor;
   void*   fAdvancedProperties;
   long   fAdvancedPropertiesSize;
   char   fPageMode;
   char   fPrintingMode;
   short   fPage;
   short   fTable;
   long   fUnused;
   char   fDraggable;
   char   fDroppable;
   short   fLook;
   void*   fMacWindow;
   void*   fMacPort;
   void*   fWinHWND;
   void*   fWinHDC;
   char   fInterProcessVariable;
} PA_PluginProperties;

(1) Is the area an interprocess ?

   char IsAreaInterprocess(PA_PluginParams params)
   {
      PA_PluginProperties   props;
      PA_GetPluginProperties(params, &props);
      
      return props.fInterProcessVariable;
   }

(2) Save the properties at initialization

   typedef struct {
      PA_PluginProperties   props;
      /* . . . other fields of this private structure . . . */
   } AREA, *AREAPTR;

   void PluginMain (long selector, PA_PluginParameters params)
   {
      switch (selector)
      {
         /* . . . */
         case 11: // in this sample, the area is 11th routine
            MyArea(params);
            break;
         /* . . . */
      }
   }

   void MyArea(PA_PluginParameters params)
   {
      AE_AreaEvent   event;
      event = PA_GetAreaEvent( params );

      switch ( event )
      {
         /* . . . */
         case eAE_Init :
         {
      // Allocate our private data
            AREA   area = malloc(sizeof(AREA);
            if(area)
            {
      // Get the properties. At Runtime, the properties can only be
      // retrieved at initialization 
               PA_GetPluginProperties(params, &area.props);

               /* . . . initialize the other fields . . . */
            }
      // "link" the reference to our private data
            PA_SetPluginReference(params, area);
         }
            break;

         /* . . . next code . . .*/
      
   }
   

Create and use an external area, PA_GetAreaEvent.

Use PA_GetLastError to see if an error occurred
