[Closed] dinamic custom control creation

Aug 02, 2007 1:44 pm

hi there,

does anyone have ever tried to append a max sdk rollup to a IRollupWindow and to fill a dialog template at runtime, rather than getting it from a cpp resource file ? We want to dinamically add custom controls to rollup at runtime. Help will be very much appreciated =)

1.) some definitions

// the rollup template
   HGLOBAL hTemplate = NULL;
   
   // control-IDs
        #define IDC_PUSHME 2000
        
        // dialog proc
        INT_PTR CALLBACK dlgProc(HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam);

  2.) create a dialogtemplate

// create a rollup template
        HGLOBAL CreateRolloutTemplate()
        {
        	HGLOBAL _hTemplate = GlobalAlloc(GPTR, sizeof(DLGTEMPLATE)+ LF_FACESIZE * 2);
        	DLGTEMPLATE* _lpTempl_Rollout = (DLGTEMPLATE*)GlobalLock(_hTemplate);
        	_lpTempl_Rollout->style = DS_SETFONT | WS_CHILD | WS_VISIBLE;
        	_lpTempl_Rollout->dwExtendedStyle = 0;
        	_lpTempl_Rollout->cdit  = 0;
        	_lpTempl_Rollout->x	= 0;
        	_lpTempl_Rollout->y	= 0;
        	_lpTempl_Rollout->cx	= 81;		
        	_lpTempl_Rollout->cy	= 100;		
        	GlobalUnlock(_hTemplate);
        
        	return _hTemplate;
        }

  3.) appendRollout

hTemplate = CreateRolloutTemplate();
        	DLGTEMPLATE* _lpTempl_Rollout = (DLGTEMPLATE*)GlobalLock(hTemplate);
        	IRollupWindow->AddRollupPage(hInstance, _lpTempl_Rollout, dlgProc, _T("mem-template"));
        	GlobalUnlock(hTemplate);

   replace "IRollupWindow" by your IRollupWindow-pointer

  4.) create controls

// the rollup proc
        INT_PTR CALLBACK dlgProc(HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam)
        {
        	switch(msg) 
        	{
        		case WM_INITDIALOG:	
        			CreateWindow("Button", "Push me", WS_CHILD | WS_VISIBLE | BS_PUSHBUTTON, 5, 5, 100, 21, hWnd, (HMENU)IDC_PUSHME, hInstance, NULL);
        			break;
        
        		default: return FALSE;
        	}
        	return TRUE;
        }

5.) when you dont need it anymore, call GlobalFree(hTemplate);
somwhere in you code

6.) good luck

any further question ? feel free to ask...
