我怀疑这是如此基本,没有人费心去记录它.
我想从我的程序中编写一个HTML文件,然后将该文件加载到QWebview对象中.
当我打开QtCreator时,我可以导航到右侧URL块中的文件,它显示在QtCreator中.当我编译并运行程序时,窗口是白色和空白的.
我也不希望目录硬编码,我希望它使用当前目录.
所以我想有两个问题:
ui->reportView->load(QUrl("???"));

谢谢.
我读了两个字符串,包括年份,朱利安日(年),小时,分钟和观察.
我使用sscanf将相关变量拉出来:
sscanf(tide_str1.c_str(), "%d %d %d %d %Lf", &y1, &j1, &h1, &m1, &obs1);
sscanf(tide_str2.c_str(), "%d %d %d %d %Lf", &y2, &j2, &h2, &m2, &obs2);

对于此特定数据集,值为2011 083 23 22 1.1
然后我创建并填充一个tm结构,运行mktime,在两天之间的cout调用,它从083变为364.
int y1=2011, j1=83, h1=23, m1=22;
struct tm time_struct = {0, 0, 0, 0, 0, 0, 0, 0, 0}, *time_ptr = &time_struct;
time_t tv_min;
time_struct.tm_year = y1 - 1900;
time_struct.tm_yday = j1;
cout << time_struct.tm_yday << endl;
time_struct.tm_hour = h1;
time_struct.tm_min = m1;
time_struct.tm_isdst = -1;
cout << time_struct.tm_yday << endl; …Run Code Online (Sandbox Code Playgroud)
