一 Group Box:组合框
#include "widget.h"#include<QGroupBox>
#include<QRadioButton>
#include<QPushButton>
#include<QVBoxLayout>//可以在水平方向和垂直方向进行排列的控件，QHBoxLayout/QVBoxLayout
#include <QGridLayout>
#include <QCheckBox>#include <QMenu>Widget::Widget(QWidget *parent): QWidget(parent)
{//组合框1：gpb_1QGroupBox *gpb_1 = new QGroupBox("单选按钮组1");QRadioButton * rbtn_1 = new QRadioButton("RadioButton1");QRadioButton * rbtn_2 = new QRadioButton("RadioButton2");QRadioButton * rbtn_3 = new QRadioButton("RadioButton3");QVBoxLayout *vbly1 = new QVBoxLayout;vbly1->addWidget(rbtn_1);vbly1->addWidget(rbtn_2);vbly1->addWidget(rbtn_3);gpb_1->setLayout(vbly1);//组合框2：gpb_1QGroupBox *gpb_2 = new QGroupBox("复选按钮组2");//gpb_2->setCheckable(true);QCheckBox *cbx1 = new QCheckBox("checkbox1");QCheckBox *cbx2 = new QCheckBox("checkbox2");QCheckBox *cbx3 = new QCheckBox("checkbox3");//全选，半选，未选cbx2->setTristate(true);//设置支持半选状态，默认不支持班选态cbx2->setChecked(true);QVBoxLayout *vbly2 = new QVBoxLayout;vbly2->addWidget(cbx1);vbly2->addWidget(cbx2);vbly2->addWidget(cbx3);gpb_2->setLayout(vbly2);//组合框3：gpb_3QGroupBox *gpb_3 = new QGroupBox("单选按钮和复选按钮组3");gpb_3->setCheckable(true);QRadioButton * rbtn_31 = new QRadioButton("RadioButton31");QRadioButton * rbtn_32 = new QRadioButton("RadioButton32");QRadioButton * rbtn_33 = new QRadioButton("RadioButton33");QCheckBox *cbx4 = new QCheckBox("checkbox4");cbx4->setCheckable(true);QVBoxLayout *vbly3 = new QVBoxLayout;vbly3->addWidget(rbtn_31);vbly3->addWidget(rbtn_32);vbly3->addWidget(rbtn_33);vbly3->addWidget(cbx4);gpb_3->setLayout(vbly3);//组合框4：gpb_4QGroupBox *gpb_4 = new QGroupBox("综合按钮组3");gpb_4->setCheckable(true);QPushButton * pbtn_4 = new QPushButton("QPushButton4");QPushButton * pbtn_5 = new QPushButton("QPushButton5");pbtn_5->setCheckable(true);QPushButton * pbtn_6 = new QPushButton("QPushButton6");//命令按钮添加子菜单QMenu *mu = new QMenu(this);mu->addAction("King");mu->addAction("Darren");mu->addAction("Mark");mu->addAction("Vico");pbtn_6->setMenu(mu);QVBoxLayout *vbly4 = new QVBoxLayout;vbly4->addWidget(pbtn_4);vbly4->addWidget(pbtn_5);vbly4->addWidget(pbtn_6);gpb_4->setLayout(vbly4);QGridLayout *gdlyout = new QGridLayout;gdlyout->addWidget(gpb_1,0,0,1,1);gdlyout->addWidget(gpb_2,0,1,1,1);gdlyout->addWidget(gpb_3,1,0,1,1);gdlyout->addWidget(gpb_4,1,1,1,1);this->setLayout(gdlyout);

二 Scroll Area:滚动区域。
#include "widget.h"#include <QApplication>#include <QLabel>
#include <QScrollArea>
#include <QGridLayout>int main(int argc, char *argv[])
{QApplication a(argc, argv);Widget w;w.resize(300,200);/** QScrollArea当中有很多功能继承来自于QAbstractScrollArea* 滚动条外观是否漂亮取决于当前滚动条策略，有时间大家可以研究一下，查官网**/QLabel *qljpg = new QLabel;qljpg->setScaledContents(true);QImage imagejpg(":/new/prefix1/Saved Pictures/02.jpg");qljpg->setPixmap(QPixmap::fromImage(imagejpg));QScrollArea *sArea = new QScrollArea;//根据窗口比例显示出来//sArea->setWidgetResizable(true);//居中sArea->setAlignment(Qt::AlignCenter);sArea->setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOn);sArea->setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOff);sArea->setWidget(qljpg);QGridLayout *glayout = new QGridLayout;glayout->addWidget(sArea);w.setLayout(glayout);w.show();return a.exec();
}
