麻烦指教下,该如何解决

麻烦指教下 - C++ Builder / Windows SDK/API
计算RichEdit的文本总高度 

通过Canvas->TextHeight得到了行文本高度,不知道行间距怎么获得？麻烦大家指教一下

[解决办法]

C/C++ code

PARAFORMAT2 pf2;ZeroMemory(&pf2, sizeof(pf2));pf2.cbSize = sizeof(pf2);SendMessage(RichEdit1->Handle, EM_GETPARAFORMAT, 0, (LPARAM)&pf2);// 行间距Caption = pf2.bLineSpacingRule;
