d2ftrgst_SetTextProp( d2fctx *pd2fctx, d2ftrg *pd2ftrg, ub2 pnum, text *prp );

This function sets the value of the specified trigger object text property. You specify a pointer to the context in pd2fctx, the trigger object in pd2ftrg, the property number in pnum, and a handle to the text value in prp.

This function returns D2FS_SUCCESS if it sets the specified text property with the value stored in prp.

d2ftrgso_SetObjectProp( d2fctx *pd2fctx, d2ftrg *pd2ftrg, ub2 pnum, dvoid *prp );

d2ftrghp_HasProp( d2fctx *pd2fctx, d2ftrg *pd2ftrg, ub2 pnum );

This function queries the specified trigger object for the specified property. You specify a pointer to the context in pd2fctx, the trigger object in pd2ftrg, and a property number in pnum.

If the function succeeds, it returns D2FS_YES or D2FS_NO, depending on whether the object has the specified property; otherwise, the function can return a number of possible return values, depending on the circumstances. For a complete list of the valid Open Forms API return values, refer to the "About Open API function return codes" section.

d2ftrgip_InheritProp( d2fctx *pd2fctx, d2ftrg *pd2ftrg, ub2 pnum );

This function enables the specified trigger object to inherit the specified property. You specify a pointer to the context in pd2fctx, a pointer to the trigger object in pd2ftrg, and the property number in pnum.

If the function succeeds, it returns D2FS_YES or D2FS_NO, depending on whether the object has been modified to inherit the specified property; otherwise, the function can return a number of possible return values, depending on the specific circumstances. For a complete list of the valid Open Forms API return values, refer to the "About Open API function return codes" section.

d2ftrgii_IspropInherited( d2fctx *pd2fctx, d2ftrg *pd2ftrg, ub2 pnum );

This function verifies that the specified object’s property is inherited, as is, from its parent object. You specify a pointer to the context in pd2fctx, a pointer to the trigger object in pd2ftrg, and the property number in pnum.

If the function succeeds, it returns D2FS_YES or D2FS_NO, depending on whether the property is inherited from the specified object’s parent; otherwise, the function can return a number of possible return values, depending on the specific circumstances. For a complete list of the valid Open Forms API return values, refer to the "About Open API function return codes" section.

d2ftrgsc_SubClass( d2fctx *pd2fctx, d2ftrg *pd2ftrg, d2fob *parent, boolean keep_path);

This function returns D2FS_SUCCESS if the specified trigger object (pd2ftrg) becomes a subclass of the specified parent (parent). You specify a pointer to the context in pd2fctx, a pointer to the trigger object in pd2ftrg, a pointer to the parent object in parent, and a boolean flag to save the path to the parent object in keep_path.

Note that the Forms API uses the boolean keep_path argument to save the actual path information. It is recommended that you do not set keep_path to TRUE since this information may be lost if you move to another machine. If keep_path is set to TRUE, the Forms API saves the actual path in the .fmb file. Therefore, the next time the form is loaded, depending on how the environment variable Forms 4.5 or 5.0 path is defined, the Forms API searches for the parent form in one of the specified directories defined by the environment variable.

d2ftrgis_IsSubclassed ( d2fctx *pd2fctx, d2ftrg *pd2ftrg );

This function verifies that the specified object is a subclass of another object. You specify a pointer to the context in pd2fctx and a pointer to the trigger object in pd2ftrg.

If the function succeeds, it returns D2FS_YES or D2FS_NO, depending on whether the specified object is a subclass of another object; otherwise, the function can return a number of possible return values, depending on the specific circumstances. For a complete list of the valid Open Forms API return values, refer to the "About Open API function return codes" section.
