QPalette的方法

#include  < QApplication >
#include  < QtGui >int  main( int  argc,  char   * argv[])
{QApplication app(argc,argv);QFrame  * frame  =   new  QFrame;frame -> resize( 400 , 700 );QPixmap pixmap("images/frame.png");QPalette   palette;palette.setBrush(frame -> backgroundRole(),QBrush( pixmap ));frame -> setPalette(palette);frame->setMask(pixmap.mask());  //可以将图片中透明部分显示为透明的frame -> setAutoFillBackground( true );frame -> show();return  app.exec();
}

setStyleSheet方法

#include  < QApplication >
#include  < QtGui >int  main( int  argc,  char   * argv[])
{QApplication app(argc,argv);QFrame  * frame  =   new  QFrame;frame ->setObjectName("myframe" );frame -> resize( 400 , 700 );frame -> setStyleSheet( " QFrame#myframe{border-image:url(images/frame.png)} "  );frame -> show();return  app.exec();
}

paintEvent事件方法

// myframe.h文件
#ifndef MYFRAME_H
#define  MYFRAME_H#include  < QWidget >
#include  < QtGui >class  MyFrame :  public  QWidget
{
public :MyFrame();void  paintEvent(QPaintEvent  * event );
};#endif   //  MYFRAME_H// myframe.cpp文件
#include  " myframe.h "MyFrame::MyFrame()
{
}void  MyFrame::paintEvent(QPaintEvent  * event )
{QPainter painter( this );painter.drawPixmap( 0 , 0 , 400 , 700 ,QPixmap( " images/frame.png " ));
}// main.cpp文件
#include  < QApplication >
#include  < QtGui >#include  " myframe.h "int  main( int  argc,  char   * argv[])
{QApplication app(argc,argv);MyFrame  * frame  =   new  MyFrame;frame -> resize( 400 , 700 );frame -> show();return  app.exec();
}

#include  < QApplication >
#include  < QtGui >int  main( int  argc,  char   * argv[])
{QApplication app(argc,argv);QFrame  * frame  =   new  QFrame;QPushButton  *  button0  =   new  QPushButton(frame);QPushButton  *  button1  =   new  QPushButton(frame);QPushButton  *  button2  =   new  QPushButton(frame);QPushButton  *  button3  =   new  QPushButton(frame);QPushButton  *  button4  =   new  QPushButton(frame);QPushButton  *  button5  =   new  QPushButton(frame);frame -> setObjectName( " myframe " );frame -> resize( 400 , 700 );frame -> setStyleSheet( " QFrame#myframe{border-image:url(images/frame.png)} "  );button0 -> setGeometry( 60 , 150 , 68 , 68 );button1 -> setGeometry( 160 , 150 , 68 , 68 );button2 -> setGeometry( 260 , 150 , 68 , 68 );button3 -> setGeometry( 60 , 280 , 68 , 68 );button4 -> setGeometry( 160 , 280 , 68 , 68 );button5 -> setGeometry( 260 , 280 , 68 , 68 );QIcon icon;QPixmap pixmap0( " images/SMS.png " );icon.addPixmap(pixmap0);button0 -> setIcon(icon);button0 -> setIconSize(QSize( 68 , 68 ));button0 -> setFixedSize(pixmap0.size());button0 -> setMask(pixmap0.mask());QPixmap pixmap1( " images/EMail.png " );icon.addPixmap(pixmap1);button1 -> setIcon(icon);button1 -> setIconSize(QSize( 68 , 68 ));button1 -> setFixedSize(pixmap1.size());button1 -> setMask(pixmap1.mask());QPixmap pixmap2( " images/Contacts.png " );icon.addPixmap(pixmap2);button2 -> setIcon(icon);button2 -> setIconSize(QSize( 68 , 68 ));button2 -> setFixedSize(pixmap2.size());button2 -> setMask(pixmap2.mask());QPixmap pixmap3( " images/Calendar.png " );icon.addPixmap(pixmap3);button3 -> setIcon(icon);button3 -> setIconSize(QSize( 68 , 68 ));button3 -> setFixedSize(pixmap3.size());button3 -> setMask(pixmap3.mask());QPixmap pixmap4( " images/GoogleVoice.png " );icon.addPixmap(pixmap4);button4 -> setIcon(icon);button4 -> setIconSize(QSize( 68 , 68 ));button4 -> setFixedSize(pixmap4.size());button4 -> setMask(pixmap4.mask());QPixmap pixmap5( " images/AndroidMarket.png " );icon.addPixmap(pixmap5);button5 -> setIcon(icon);button5 -> setIconSize(QSize( 68 , 68 ));button5 -> setFixedSize(pixmap5.size());button5 -> setMask(pixmap5.mask());frame -> show();return  app.exec();
