Qt之QPushButton類

 

一、以下代碼展示了QPushButton的用法以及各種不同的按鈕

pushbutton.h 

#ifndef PUSHBUTTON_H#define PUSHBUTTON_H#include <QWidget>class QPushButton;class QHBoxLayout;class pushbutton:public QWidget{        Q_OBJECT        public:                pushbutton();        private:                QPushButton *pushbutton_1;                QPushButton *pushbutton_2;                QPushButton *pushbutton_3;                QPushButton *pushbutton_4;                QHBoxLayout *layout;};#endif

pushbutton.cpp

#include <QtGui>#include "pushbutton.h"pushbutton::pushbutton(){        pushbutton_1=new QPushButton;        pushbutton_1->setIcon(QIcon("1.png"));        //設定按鈕的表徵圖        pushbutton_2=new QPushButton("ToggleButton");        pushbutton_2->setCheckable(TRUE);            //設定按鈕為可以按下，預設是不能按下的            pushbutton_2->setChecked(TRUE);              //設定按鈕預設為安心啊狀態        pushbutton_3=new QPushButton("Flat Button");     

        pushbutton_3->setFlat(TRUE);               //設定按鈕為水平狀態，預設是突出        pushbutton_4=new QPushButton("PopMenu");    // 設定按鈕為快顯功能表        QMenu *menu=new QMenu;        menu->addAction("action 1");        menu->addAction("action 2");        pushbutton_4->setMenu(menu);        layout=new QHBoxLayout(this);                //設定布局管理器        layout->addWidget(pushbutton_1);        layout->addWidget(pushbutton_2);        layout->addWidget(pushbutton_3);        layout->addWidget(pushbutton_4);        layout->addStretch();        }
