Selection handling

[vdentello]

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.

[vdentello]

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.

[BerndSchwarzenbacher]

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,...).
