Solved 2024 Conversion questions

Hello,

I have a few questions about 2024 conversion that I am combining into 1 post.
The plugin is a object data plugin with resource description.

1. GetDParameter bitmapbutton

Bool GetDParameter(GeListNode *node, const DescID &id, GeData &t_data, DESCFLAGS_GET &flags)
{
	
	switch (id[0].id) 
	{
		case MY_BITMAP:
		{
			Int32 dirty = 0;
			BitmapButtonStruct bbs(static_cast<BaseObject*>(node), id, dirty);
			t_data = GeData(CUSTOMDATATYPE_BITMAPBUTTON, bbs);  // ERROR
			flags |= DESCFLAGS_GET::PARAM_GET;
			break;
		}

2. BaseSelect

BaseSelect* bs;

			if (polygonCnt > 0)
			{
				SelectionTag* sTag = SelectionTag::Alloc(Tpolygonselection); 
myObj->InsertTag(sTag, 0);
			
		
				bs = sTag->GetBaseSelect();   // ERROR

3. IncludeExclude

InExcludeData* myList= (InExcludeData*)bc->GetCustomDataType(MY_ID, CUSTOMDATATYPE_INEXCLUDE_LIST);   // ERROR

Thanks.

Hey @Rox,

Thank you for reaching out to us. You really should have a look at the migration guide, as these topics are covered there. We cannot debug every compiler error here for you, nevertheless here are the answers to your three problems:

// 1 - That should fix it as the signature is now:
//    GeData( const CustomDataType & data, Int32 type )	
t_data = GeData(bbs, CUSTOMDATATYPE_BITMAPBUTTON); 

// 2 - Selections are now COW and make a distinction between being mutable and immutable. 
const BaseSelect* const mySelection = sTag->GetBaseSelect();   // immutable
BaseSelect* const mySelection = sTag->GetWritableBaseSelect(); // mutable

// 3 - Same story here, GetCustomDataType returns immutable data now, the method is also templated 
// now, so you do not need to cast things anymore.
const InExcludeData* const myList= bc->GetCustomDataType<InExcludeData>(MY_ID);
InExcludeData* const myList= bc->GetCustomDataTypeWritableObsolete<InExcludeData>(MY_ID);

Cheers,
Ferdinand

edit: forgot the template argument in BaseContainer::GetCustomDataType
