[Closed] TYPE_MTLBUTTON and drag/drop?

not so, works with drag and drop from the material editor to particleflow…

this is the paramblock def from \maxsdk\samples\ParticleFlow\Actions\PFOperatorMaterialStatic_ParamBlock.cpp

// materialStatic
  			kMaterialStatic_material,	_T("Assigned_Material"),
  									TYPE_MTL,
  									P_RESET_DEFAULT|P_SHORT_LABELS|P_NO_REF,
  									IDS_ASSIGNEDMATERIAL,
  			// optional tagged param specs
  					p_ui,			TYPE_MTLBUTTON,	IDC_MATERIAL,
  			end,

also in the resource dialog make IDC_MATERIAL class as [b]CustButton

[/b]you then have to initialize the button with ICustom::SetDADMgr(DADMgr *dad)

yeah it’s pretty simple to implement

as above in the dialog resource create the custom control with class set to [b]CustButton [/b]with id
as [b] IDC_MATERIAL[/b]

define your mtl param as so....

    	kmtn_material,	_T("material"), TYPE_MTL, P_SHORT_LABELS, IDS_ASSIGNEDMATERIAL,
    		p_ui,			TYPE_MTLBUTTON,	IDC_MATERIAL,
    	end,

in the param block desc

then in create panel dialog handler proc as so.....

class MapToNormalModDlgProc : public ParamMap2UserDlgProc , DADMgr
    {
    public:
    
    	MapToNormalMod*	mod;
    	HWND			panelhWnd;
    
    	MapToNormalModDlgProc(MapToNormalMod* m) { mod = m;}
    	INT_PTR DlgProc(TimeValue t, IParamMap2 *map, HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam);
    	void InitPanel(TimeValue t);
    	void DeleteThis() { delete this; }
    
    // from DADMgr
    
    	SClass_ID GetDragType(HWND hwnd, POINT p) { return MATERIAL_CLASS_ID; }
    	BOOL OkToDrop(ReferenceTarget *dropThis, HWND hfrom, HWND hto, POINT p, SClass_ID type, BOOL isNew)
    	{
    		if (hfrom == hto) 
    			return FALSE;
    		return (type==MATERIAL_CLASS_ID) ? TRUE : FALSE;
    	}
    	int SlotOwner() { return OWNER_SCENE; }  
    	ReferenceTarget *GetInstance(HWND hwnd, POINT p, SClass_ID type)
    	{
    		if(!mod) 
    			return NULL;
    
    		return mod->pblock->GetMtl(kmtn_material);
    	}
    	void Drop(ReferenceTarget *dropThis, HWND hwnd, POINT p, SClass_ID type, DADMgr* srcMgr = NULL, BOOL bSrcClone = FALSE)
    	{
    		Mtl *mtl = (Mtl *)dropThis;
    
    		if(mod && mtl) 
    			mod->pblock->SetValue(kmtn_material,0,mtl);
    	}
    	BOOL AutoTooltip() { return TRUE; }
    };
    
    //********************************************************************************************
    
    void MapToNormalModDlgProc::InitPanel(TimeValue t)
    { 
    	if(!panelhWnd) 
    		return;
    
    	ICustButton* but = GetICustButton(GetDlgItem(panelhWnd, IDC_MATERIAL));
    	but->SetDADMgr(this);
    	ReleaseICustButton(but);
    }
    
    //********************************************************************************************
    
    INT_PTR MapToNormalModDlgProc::DlgProc(TimeValue t, IParamMap2 *map, HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam)
    {
    	panelhWnd = hWnd;
    	switch (msg) 
    	{
    		case WM_INITDIALOG: 
    		{
    			InitPanel(t);
    			break;
    		}
    		case WM_COMMAND:
    		{
    			switch (LOWORD(wParam)) 
    			{
    /*				case IDC_DIALOG_ITEM:
    				{
    					return TRUE;
    				}*/
    			}
    			break;
    		}
    	}
    	return FALSE;
    }

// create the dialog handler like so in BeginEditParams....

my_param_desc.SetUserDlgProc(new MapToNormalModDlgProc(this));

i added it to a simple mod i had and it works fine should work for any dialog handler. Works for both drag and drop and as mtl button

Thank you!

I’ve been out for a week, so sorry for being so late, it looks so useful but having inheritance from the plugin wizard (simplymod2 or modifier) since they use IParamBlock2 I didn’t manage to make it work.

Could you post your entire simply example?
