引言
之前做项目的时候，需要自己生成一个pdf文件，好久之前保存的草稿，今天就把它发表一下吧，留着自己以后有需要的时候在来查阅。
QString ReportMainWindow::createPdfFile()
{
QString strDirPath = QDir::tempPath() + "/TempPdf";
QDir dir(strDirPath);
if (!dir.exists())
{
bool bIsCreate = dir.mkdir(strDirPath);

}
QString strPdfFile = strDirPath + "/temp.pdf";
QFile pdfFile(strPdfFile); // 输出文件名
if (!pdfFile.open(QIODevice::WriteOnly))
{

return strPdfFile = "";
}
QPdfWriter *pdfWriter =
new QPdfWriter(&pdfFile); // 实例化QPdfWriter 可以设置PDF文件的一些参数
pdfWriter->setPageSize(QPagedPaintDevice::A4); // 设置纸张为A4纸
pdfWriter->setResolution(
QPrinter::ScreenResolution); // 设置分辨率 屏幕分辨率 打印机分辨率
// 高分辨率
pdfWriter->setPageMargins(
QMarginsF(30, 30, 30, 30)); // 设置页边距 顺序是:左上右下

注意
以上这段代码只是简单的提供了一些思路，真正项目中将将一个界面中的内容生成指定格式的pdf需要自己再重新实现。
