1.horizontal line 和vertical line 的使用
horizontal line 和vertical line 實際上是由QFame類，設置相應的參數來實現的；而不是由單獨的類來實現的，例如（QHorizontalLine/QVerticalLine）；
1.1.控件拖拽
1.2.代碼實現
1 QFrame *line = new QFrame(); 2 line->setFrameShape(QFrame::HLine); 3 line->setFrameShadow(QFrame::Plain); 4 //line->raise();//頂層展示
2.horizontal line 和vertical line 在QGridLayout 中的應用
以下為代碼實現：
1 #include "mainwindow.h"
2 #include "ui_mainwindow.h"
3 #include "testform.h"
4 #include <QDebug>
5 #include <QGridLayout>
6 #include <QHBoxLayout>
7 #include <QPushButton>
8 #include <QLabel>

11 MainWindow::MainWindow(QWidget *parent) : 12 QMainWindow(parent), 13 ui(new Ui::MainWindow) 14 { 15 ui->setupUi(this); 16
17 QGridLayout *m_Layout = new QGridLayout(this); 18 m_Layout->setSpacing(5);//setVerticalSpacing()/setHorizontalSpacing() 19
20 //1.創建標題1
21 QLabel *m_title = new QLabel(tr("題目1")); 22 m_title->setMinimumHeight(50); 23 m_title->setMaximumHeight(60); 24 m_title->setAlignment(Qt::AlignCenter); 25 m_Layout->addWidget(m_title, 0, 0, 1, 1); 26
27 //分割線
28 QFrame *line = new QFrame(); 29 line->setFrameShape(QFrame::HLine); 30 line->setFrameShadow(QFrame::Plain); 31 //line->raise();//頂層展示
32 m_Layout->addWidget(line,1,0,1,1); 33
34 //2.創建標題2
35 m_title = new QLabel(tr("題目2")); 36 m_title->setAlignment(Qt::AlignCenter);//Qt::AlignHCenter|Qt::AlignTop
37 m_Layout->addWidget(m_title, 2, 0, 1, 1); 38
39 resize(400, 4*30); 40 ui->centralWidget->setLayout(m_Layout); 41 } 42
43 MainWindow::~MainWindow() 44 { 45 delete ui; 46 }
呈現效果：
