示例1: l_font_draw_tooltip
static int l_font_draw_tooltip(lua_State *L)
{
THFont* pFont = luaT_testuserdata<THFont>(L);
THRenderTarget* pCanvas = luaT_testuserdata<THRenderTarget>(L, 2);
size_t iMsgLen;
const char* sMsg = luaT_checkstring(L, 3, &iMsgLen);
int iX = static_cast<int>(luaL_checkinteger(L, 4));
int iY = static_cast<int>(luaL_checkinteger(L, 5));
int iScreenWidth = pCanvas->getWidth();
int iW = 200; // (for now) hardcoded width of tooltips
uint32_t iBlack = pCanvas->mapColour(0x00, 0x00, 0x00);
uint32_t iWhite = pCanvas->mapColour(0xFF, 0xFF, 0xFF);
THFontDrawArea oArea = pFont->drawTextWrapped(nullptr, sMsg, iMsgLen, iX + 2, iY + 1, iW - 4, INT_MAX, 0);
int iLastX = iX + oArea.iWidth + 3;
int iFirstY = iY - (oArea.iEndY - iY) - 1;
int iXOffset = iLastX > iScreenWidth ? iScreenWidth - iLastX : 0;
