| Hi, I've got an error when I compile my code: Compiling:gui_example.bmx [ERROR]: Compile Error: Unable to convert from 'Int(Int,Int,Int Ptr,Int Ptr)' to 'Int' [ERROR]: [e:/blitzmaxbeta103/wingui/gui.bmx;451;1] [ERROR]: Build Error: failed to compile e:/blitzmaxbeta103/wingui/gui_example.bmx In fact the function SetWindowLong need a function for it ast parameter. But I don't know how we can put a function as parameter. If someone know it, tell me! here is the code: Type TButton Extends ButtonEvents Method Create$(txt$,x,y,w,h,group) Self.hwnd=CreateWindowEx_( Null, "BUTTON" , txt$ ,WS_CHILD | WS_VISIBLE | WS_CLIPSIBLINGS | BS_PUSHBUTTON ,x, y, w, h, group, Null ,GetModuleHandleA(Null), Null ) ButtonProc_=SetWindowLongA( Self.hwnd, GWL_WNDPROC, ButtonProc ) SendMessage_( Self.hwnd, WM_SETFONT, GetStockObject(DEFAULT_GUI_FONT), True ) Self.posx=x Self.posy=y Self.sizew=w Self.sizeh=h Self.oldwidth=w Self.oldleft=x FlushMem() End Method End Type Function ButtonProc(hwnd:Int,msg:Int,wparam:Int Ptr,lparam:Int Ptr) Select msg Case 15 'Paint buttonmsg_=15 Case 512 'Mouse Enter buttonmsg_=512 Case $2A3 'Mouse Leave buttonmsg_=$2A3 Case $2A1 'Mouse Enter buttonmsg_=$2A1 Case 244 'Style Changed buttonmsg_=244 Case 12 'Text Changed buttonmsg_=12 Case 514 buttonmsg_=514 Case 7 buttonmsg_=7 Case 8 buttonmsg_=8 End Select buttonhwnd_=hwnd FlushMem() Return CallWindowProcA( (ButtonProc_), hwnd, msg, wparam, lparam) 'Return buttonmsg_ 'Return buttonhwnd_ End Function |
