前言
本章节会给大家带来基于文本编辑器 Easy Word V1.1开发升级到Easy Word V1.2开发的解析。
一、文本编辑器 Easy Word V1.2 槽函数与框架连接解析
1.1、缩放功能
(1)在 “mainwindow.h” 头文件中添加 “private slots:” 变量：
void ShowZoomIn(); //缩放功能放大- 1
(2)在 createActions() 函数的”“放大“动作“最后添加事件关联：
connect(zoomInAction,SIGNAL(triggered()),this,SLOT(ShowZoomIn()));- 1
(3)实现图形放大功能的函数 ShowZoomln()如下：
void MainWindow::ShowZoomIn() //图像放大 { if(img.isNull()) //有效性判断 { return; } QMatrix matrix; //声明一个QMatrix类的实例 matrix.scale(2,2); //(a) img = img.transformed(matrix); showWidget->imageLabel->setPixmap(QPixmap::fromImage(img)); }- 1

其中， matrix.scale(2,2)、 img = img.transformed(matrix)：按照 2 倍比例对水平和垂直方向进行放大，并将当前显示的图形按照该坐标矩阵进行转换。QMatrix & QMatrix::scale(qreal sx,qreal sy)函数返回缩放后的 matrix 对象引用，若要实现 2
倍比例的缩小，则将参数 sx 和 sy 改为 0.5 即可。
(4)在 “mainwindow.h” 头文件中添加 “private slots:” 变量：void ShowZoomOut(); //缩放功能缩小- 1
(5)在 createActionsO 函数的＂＇＇缩小“动作“最后添加事件关联：
connect (zoomOutAction, SIGNAL(triggered ()), this, SLOT (ShowZoomOut()));- 1
(6)实现图形缩小功能的函数 ShowZoomOutO如下：
void MainWindow::ShowZoomOut() //图像缩小 { if (img.isNull()) { return; } QMatrix matrix; matrix.scale(0.5,0.5); //(a) img=img.transformed(matrix); showWidget->imageLabel->setPixmap(QPixmap::fromImage(img)); }- 1

其中，
(a)scale(qreal sx,qreal sy): 此函数的参数是 qreal 类型值。 qreal 定义了一种 double 数据类
型，该数据类型适用于所有的平台。需要注意的是，对千 ARM 体系结构的平台， qreal 是一种float 类型 。 在 Qt 5 中还声明了 一 些指定位长度的数据类型，目的是保证程序能够在 Qt 支待的所有平台上正常运行。例如， qint8 表示一个有符号的 8 位字节， qlonglong 表示 long long int 类型，与 qint64 相同。1.2、旋转功能
ShowRotate90()函数实现的是图形的旋转，此函数实现坐标的逆时针旋转 90° 。
(1)在 “mainwindow.h” 头文件中添加 “private slots:” 变量：void ShowRotate90(); //旋转90°- 1
(2)在 createActionsO函数的“旋转 90°" 最后添加事件关联：
connect(rotate90Action, SIGNAL (triggered()), this, SLOT (ShowRotate90()));- 1
(3)ShowRotate90()函数的具体实现代码如下：
void MainWindow::ShowRotate90() //旋转90° { if(img.isNull()) { return; } QMatrix matrix; matrix.rotate(90); img = img.transformed(matrix); showWidget->imageLabel->setPixmap(QPixmap::fromImage(img)); }- 1

(4)在 “mainwindow.h” 头文件中添加 "private slots : " 变量：
void ShowRotate180(); //旋转180° void ShowRotate270 (); //旋转270°- 1
- 2
(5)在 createActions() 函数的“旋转 180°" “旋转 270°” 最后分别添加事件关联：
connect(rotate180Action, SIGNAL (triggered()), this, SLOT (ShowRotate180())); connect(rotate270Action, SIGNAL (triggered()), this, SLOT (ShowRotate270()));- 1
- 2
(6)ShowRotate 180() 、 ShowRotate270()函数的具体实现代码如下：
void MainWindow::ShowRotate180() //旋转180° { if(img.isNull()) { return; } QMatrix matrix; matrix.rotate(180); img = img.transformed(matrix); showWidget->imageLabel->setPixmap(QPixmap::fromImage(img)); } void MainWindow::ShowRotate270() //旋转270° { if(img.isNull()) { return; } QMatrix matrix; matrix.rotate(270); img = img.transformed(matrix); showWidget->imageLabel->setPixmap(QPixmap::fromImage(img)); }- 1

1.3、镜像功能
ShowMirrorVertical() 函数实现的是图形的纵向镜像， ShowMirrorHorizontal() 函数实现的则是横向镜像。通过 Qlmage::mirrored(bool horizontal,bool vertical) 实现图形的镜像功能，参数horizontal 和 vertical 分别指定了镜像的方向。具体实现步骤如下。
(1)在 “mainwindow.h” 头文件中添加 “private slots:” 变量：void ShowMirrorVertical(); //纵向 void ShowMirrorHorizontal (); //横向- 1
- 2
(2)在 createActionsO 函数的“纵向镜像”“横向镜像“最后分别添加事件关联：
connect (mirrorVerticalAction, SIGNAL (triggered()), this, SLOT (ShowMirrorVertical())); connect (mirrorHorizontalAction, SIGNAL (triggered()), this, SLOT (ShowMirrorHorizontal ()));- 1
- 2
(3)ShowMirrorVertical()、 ShowMirrorHorizontal ()函数的具体实现代码如下：
void MainWindow::ShowMirrorVertical() //纵向镜像 { if(img. isNull ()) return; img=img.mirrored(false,true); showWidget->imageLabel->setPixmap(QPixmap::fromImage(img)); } void MainWindow::ShowMirrorHorizontal() //横向镜像 { if(img. isNull ()) return; img=img.mirrored(true,false); showWidget->imageLabel->setPixmap(QPixmap::fromImage(img)); }- 1
