hi,
I'm a bit surprised that your render can be triggered from a NodeData (but why not)
But i don't understand why you can't use GetDDescription to update your node.
That's what i did (in a probably too naive way) but you got the idea. I just got a boolean display_aboard on my ObjectData and i switch it as i needed.
If i presse the button, i switch and i set dirty my node, if i receive the message that the render is finished (or stopped) i set my bool to false and i SetDirty my node.
static const Int32 g_pc12584ButtonID = 1000;
class pc12584_object : public ObjectData
{
INSTANCEOF(pc12584_object, ObjectData);
public:
static NodeData* Alloc() { return NewObjClear(pc12584_object); };
Bool Init(GeListNode* node) override
{
display_aboard = false;
return true;
}
BaseObject* GetVirtualObjects(BaseObject* op, HierarchyHelp* hh) override
{
BaseObject* null = BaseObject::Alloc(Onull);
return null;
}
Bool GetDDescription(GeListNode* node, Description* description, DESCFLAGS_DESC& flags) override
{
if (!description->LoadDescription(Obase))
return false;
const DescID* singleid = description->GetSingleDescID();
const Int32 ID = g_pc12584ButtonID;
const DescID cid = DescLevel(ID, DTYPE_BUTTON, 0);
if (!singleid || cid.IsPartOf(*singleid, nullptr))
{
BaseContainer bc = GetCustomDataTypeDefault(DTYPE_BUTTON);
bc.SetInt32(DESC_CUSTOMGUI, CUSTOMGUI_BUTTON);
if (display_aboard)
bc.SetString(DESC_NAME, "Aboard Render"_s);
else
bc.SetString(DESC_NAME, "Render"_s);
bc.SetInt32(DESC_ANIMATE, DESC_ANIMATE_OFF);
bc.SetInt32(DESC_SCALEH, 1);
description->SetParameter(cid, bc, DescLevel(ID_OBJECTPROPERTIES));
}
flags |= DESCFLAGS_DESC::LOADED;
return SUPER::GetDDescription(node, description, flags);
}
Bool Message(GeListNode* node, Int32 type, void* data) override
{
switch (type)
{
case MSG_DESCRIPTION_COMMAND:
{
DescriptionCommand* dc = (DescriptionCommand*)data;
const Int32 id = dc->_descId[0].id;
if (id == g_pc12584ButtonID)
{
display_aboard = !display_aboard;
node->SetDirty(DIRTYFLAGS::DESCRIPTION);
}
break;
}
case g_pc12584Message:
{
display_aboard = false;
node->SetDirty(DIRTYFLAGS::DESCRIPTION);
break;
}
}
return SUPER::Message(node, type, data);
};
private:
Bool display_aboard = false;
};
// function to send a message to the ObjectData.
static maxon::Result<void> PC12854_Message(BaseDocument* doc)
{
iferr_scope;
// update the first object
BaseObject* op = doc->GetFirstObject();
if (op == nullptr)
return maxon::NullptrError(MAXON_SOURCE_LOCATION);
op->Message(g_pc12584Message);
return maxon::OK;
}
Cheers,
Manuel
