Selection handling

Hello! I've been trying to modify an element selection, but I'm having no success pulling the desired guids. It counts the elements in the selection.

ACAPI_Element_GetElemList (API_WallID, &elemList); would work but actually only selects things accoding to the first ever selection. After that, it'll only modify the elements first selected. can't reset selection.

element.header.guid = elemList[i].guid; did the trick, selNeigs[I].guid won't, it compiles without warnings though.

I've tried ACAPI_Selection_GetSelectedElement(&selNeigs, &elemList); but it's not recognized.

API_SelectionInfo selectionInfo; GS::Array<API_Neig> selNeigs; // GS::Array<API_Guid> elemList; ACAPI_Selection_Get (&selectionInfo, &selNeigs, false, false); GSErrCode err = ACAPI_CallUndoableCommand ("Wall change", [&] () -> GSErrCode { // ACAPI_Selection_GetSelectedElement(&selNeigs, &elemList); // err = ACAPI_Element_GetElemList (API_WallID, &elemList); for (uint32 i = 0; i < selNeigs.GetSize () && err == NoError; ++i) { API_Element element = {}; element.header.guid = selNeigs[i].guid; // element.header.guid = elemList[i].guid; if (ACAPI_Element_Get (&element) == NoError) { /* do what you want */ ACAPI_Element_Get (&element); // FlipWall(element.header.guid);

Made it work with a lot of trial and error.
This time, it was able to request the guids from the selected Neigs without using:

ACAPI_Selection_GetSelectedElement

Actually, I declared GSErrCode err = NoError; and then just tried err = ACAPI_Selection_Get instead and it did the trick. For reference, the way it actually worked (selection_get will also work before callUndoable):

GSErrCode err = NoError; API_SelectionInfo selectionInfo; GS::Array<API_Neig> selNeigs; err = ACAPI_CallUndoableCommand ("Wall change", [&] () -> GSErrCode { err = ACAPI_Selection_Get (&selectionInfo, &selNeigs, false, false); for (uint32 i = 0; i < selNeigs.GetSize () && err == NoError; ++i) { API_Element element = {}; element.header.guid = selNeigs[i].guid; if (ACAPI_Element_Get (&element) == NoError) { /* do what you want */ ACAPI_Element_Get (&element); // FlipWall(element.header.guid);

Hi Vítor,

ACAPI_Selection_GetSelectedElement is only available since AC27. So if you are using <=AC26 you'll have to use ACAPI_Selection_Get as you've found.

In any case, ACAPI_Selection_GetSelectedElement would have to take an input from an auxiliary function as it seems? ACAPI_Selection_Get actually outs outs the neighs, that could be converted.

Ups sry! you are right. ACAPI_Selection_Get stays the same in AC27.

The AC26 equivalent to ACAPI_Selection_GetSelectedElement is ACAPI_Goodies(APIAny_GetSelectedElementID,...).
