Change LONG_CYCLE selected Item.
-
Hello,
I am creating a CUSTOMGUI_CYCLE with my own attributes using getDDescription function. Everything goes fine until the point where I want to change the selected item. Assume that I have the following code, the Item with id 0 will be selected by default. Is there any way that I can change this? Like after a specific action the Item 1 will be selected? I tried many things but I could not find the right one. the .SetInt32(Id,value) method does not seem to work for this case as well.I also tried GetDParameter and other possible ways to do this but still could not solve this.BaseContainer settings = GetCustomDataTypeDefault(DTYPE_LONG); settings.SetString(DESC_NAME, "Drop Down"_s); settings.SetInt32(DESC_CUSTOMGUI, CUSTOMGUI_CYCLE); // add cycle elements BaseContainer items; items.SetString(0, "Item 1"_s); items.SetString(1, "Item 2"_s); items.SetString(2, "Item 3"_s); settings.SetContainer(DESC_CYCLE, items);
Thank you.

hello,
You can set the default value you want in your Init function.
In any case, the Cycle will show the value corresponding to the value of the parameter.#define MY_CYCLE_ID 1000 class DefaultCycleValue : public ObjectData { INSTANCEOF(DefaultCycleValue, ObjectData) public: virtual Bool Init(GeListNode *node) { // set the parameter the value we want, the Custom GUI will show the corresponding line in the box. node->SetParameter(DescID(MY_CYCLE_ID), GeData(1), DESCFLAGS_SET::NONE); return true; }; virtual Bool GetDDescription(GeListNode* node, Description* description, DESCFLAGS_DESC& flags) override { if (!description->LoadDescription(node->GetType())) return false; const DescID* singleid = description->GetSingleDescID(); const DescID cid = DescLevel(MY_CYCLE_ID, DTYPE_LONG, 0); if (!singleid || cid.IsPartOf(*singleid, nullptr)) { // add the parameter as long BaseContainer bc = GetCustomDataTypeDefault(DTYPE_LONG); // set the custom GUI to a cycle. bc.SetInt32(DESC_CUSTOMGUI, CUSTOMGUI_CYCLE); bc.SetString(DESC_NAME, "Long Cycle"_s); bc.SetInt32(DESC_SCALEH, 1); // cycle elements BaseContainer items; items.SetString(0, String("Item 0")); items.SetString(1, String("Item 1")); items.SetString(2, String("Item 2")); bc.SetContainer(DESC_CYCLE, items); // icons BaseContainer icons; icons.SetInt32(0, IDM_COPY); icons.SetInt32(1, IDM_CUT); icons.SetInt32(2, IDM_DELETE); bc.SetContainer(DESC_CYCLEICONS, icons); description->SetParameter(cid, bc, ID_OBJECTPROPERTIES); } flags |= DESCFLAGS_DESC::LOADED; return SUPER::GetDDescription(node, description, flags); }; static NodeData *Alloc() { return NewObjClear(DefaultCycleValue); } };

That's exactly what the code is doing in the
Init()
function usingSetParameter()
. You change the value of the parameter, the UI show the item with that value in the list. So by default the parameter value is 1 so the UI show the item with the value 1 "Item 1"If you want to change the item somewhere else, same thing just change the value of the parameter, the ui will follow.
node->SetParameter(DescID(MY_CYCLE_ID), GeData(1), DESCFLAGS_SET::NONE);
I'am adding an answer here as it is a related. But for your second question if the answer doesn't fit your need, please open a new thread and post your question in a new thread. That will help us to keep things organized.

If i understand the question, you have to check for MSG_DESCRIPTION_CHECKUPDATE message type in the
Message()
function as follow.virtual Bool Message(GeListNode* node, Int32 type, void* data) override { switch (type) { case MSG_DESCRIPTION_CHECKUPDATE : { DescriptionCheckUpdate* dcu = static_cast<DescriptionCheckUpdate*>(data); if (dcu == nullptr) return true; maxon::Int32 id = (*(dcu->descid))[0].id; if (id == MY_CYCLE_ID) { DiagnosticOutput("Cycle have been changed"); // ... do Something } break; } } return true; };
