28 | screen_width=screenGeometry.width(); 29 | screen_height=screenGeometry.height(); 30 | ``` 31 | 2. **截图API** 32 | 33 | ``` 34 | QScreen *screen = QGuiApplication::primaryScreen(); 35 | originalPixmap = screen->grabWindow(0,x,y,width,height); 36 | ``` 37 | 38 | 其实，在有了以上两个知识后，我们就已经可以截取屏幕上的任意区域的图片了。 39 | grabWindow这个函数我也最关心的就是四个参数x,y,width,height。这四个参数就是一个矩形框参数，只要给定了这四个参数，想截哪里截哪里。 40 | 比如我想截取屏幕上的从点(30,50)-->(240,350)的区域截图 41 | 42 | ``` 43 | QScreen *screen = QGuiApplication::primaryScreen(); 44 | originalPixmap = screen->grabWindow(0,30,50,(240-30),(350-50)); 45 | ``` 46 | 47 | ## 思考 48 | 那么用户在使用过程中，如何通过交互将这四个参数传递给程序呢？方法还是很多的，比如： 49 | 1. 我设计四个输入框，用户在截屏前先手动输入这四个参数对应的值，然后点击按键截屏。嗯...想想都感觉好傻。 50 | 2. 用鼠标选定一个区域，然后将矩形区域转化为这四个参数值，然后截屏。嗯大家都是这么干的，既然如此，我也这么来吧。 51 | 52 | 那么，我们的方案基本定下来了，即用户通过点击左键并拖动鼠标来选择需要截屏的区域，然后程序将坐标传递给grabWindow，从而完成截图。 53 | 54 | 1. 由于我们需要通过点击鼠标、拖动鼠标这些动作完成一些特定的功能，所以我们需要重载各种鼠标事件。 55 | 2. 为了让用户知道自己拖动的范围在什么地方，所以在拖动时要绘制出矩形的图形，即我们需要绘制矩形。 56 | 57 | 所以我们的步骤是： 58 | 1. 用户触发截图动作 59 | 2. 用户开始截图，按下鼠标左键然后拖动来选定区域，并实时将选在的区域显示在屏幕上 60 | 3. 完成截图，图片保存到本地或剪切板 61 | 62 | ## 深入 63 | 现在有了上面的步骤，我们就按照这个步骤来实现，我们可以看到，主要的任务都在第二步。 64 | 那么要实现第二步，我们又会想到一些问题： 65 | 66 | ``` 67 | 问：我们要绘制矩形框，这个矩形框绘制在什么上面？ 68 | 思考：由QT的特性可以绘制在QWidget或者继承自QWidget的控件上 69 | 答:QWidget及QWidget属性控件 70 | ``` 71 | 72 | ``` 73 | 问：这个控件有什么特性？ 74 | 思考：我们来仔细思考一下截图时拖动选框的过程，首先我们能看到整个屏幕当前的画面，然后鼠标可以在整个屏幕范围移动，绘制区域可以在整个屏幕内选择。 75 | 当然还有一点，我们鼠标的动作都是在这个控件上完成的，那么这个控件必须在所有窗体的顶层，即置顶。 76 | 答：全屏，显示屏幕画面，置顶 77 | ``` 78 | 79 | ``` 80 | 问：全屏和置顶好实现，显示屏幕画面怎么弄？ 81 | 思考：由于我们的绘图控件是全屏的，并且置顶的，那么其实屏幕画面是在这个绘图控件的下面，即要截屏的画面被绘图控件(以下称为画布)挡住了。 82 | 所以要实现画布显示屏幕画面有两种方法。 83 | 第一种就是让画布透明，画布是透明的，自然就能够显示到下面的屏幕画面了。 84 | 第二种方法就是在屏幕画面被画布挡住之前将屏幕截下来，然后将这个截取的图片显示到幕布上，此处我们用第二种方法来实现。 85 | 答：在画布显示之前先截取屏幕图片，然后显示画布，然后之前截取的屏幕画面在画布上显示。 86 | ``` 87 | 88 | 所以。通过以上的问答，基本就确定了我们的设计思路。 89 | 90 | ## 最终思路 91 | 92 | 1、触发截图(快捷键或单击图标) 93 | 2、截取全屏画面 94 | 3、显示画布，画布全屏，画布置顶，画布显示之前截取的全屏画面 95 | 4、通过重写鼠标和绘图函数来达到显示鼠标拖动区间， 96 | 5、截取鼠标拖动区间图案，弹出保存选项 97 | 6、手动调整截图区域 98 | 7、添加线、矩形以及椭圆标记功能，设置标记画笔 99 | 8、保存截屏到文件或保存截屏到剪切板或放弃截屏 100 | 9、退出 101 | 102 | ## 待完善功能 103 | 1、标记大小位置调整 104 | 105 | # 多语言 106 | 本源码提供了两种内置语言的翻译文件：英文和中文。 107 | - 英文翻译文件:en.ts 108 | - 中文翻译文件:zh_cn.ts 109 | 110 | ## 使用方法 111 | ### 1、生成ts对应的qm文件 112 | 方法一：使用打开源代码，选择"工具"->"外部"->"Qt语言专家"->"发布翻译"，然后得到对应的qm文件。 113 | 方法二：直接使用qtcreator对应的翻译家Linguist生成对应的qm文件，具体使用方法自行了解。 114 | ### 2、将qm文件放置于运行目录下 115 | 使用qtcreator时编译调试时类似于build-ScreenShotTool-Desktop_Qt_5_9_0_MinGW_32bit-Debug目录下 116 | 发布时请至于ScreenShotTool执行程序的同级目录下 117 | 118 | # 使用 119 | 使用很简单，无需过多介绍，展示一些示意图 120 | 英文界面 121 | 122 | ![英文界面](https://raw.githubusercontent.com/qiuzhiqian/ScreenShotTool/master/doc/1.jpg) 123 | 124 | 中文界面 125 | 126 | ![中文界面](https://raw.githubusercontent.com/qiuzhiqian/ScreenShotTool/master/doc/2.jpg) 127 | 128 | ## 提醒 129 | 130 | 如果发现软件的中文无法起作用，可以按以下步骤处理： 131 | 1、请确保你的软件安装目录下面有en.qm何zh_cn.qm这两个文件 132 | 2、如果有这两个文件，但仍然不起作用，请确保你的qm文件和本软件的版本是兼容的 133 | 3、如果以上的方法都没有用，请下载本软件源码，自行编译二进制文件，同时更新qm文件 134 | 4、如果以上还无法解决，请联系我 -------------------------------------------------------------------------------- /ScreenShotTool.pro: -------------------------------------------------------------------------------- 1 | #------------------------------------------------- 2 | # 3 | # Project created by QtCreator 2017-07-18T14:06:17 4 | # 5 | #------------------------------------------------- 6 | 7 | QT += core gui 8 | 9 | greaterThan(QT_MAJOR_VERSION, 4): QT += widgets 10 | 11 | TARGET = ScreenShotTool 12 | TEMPLATE = app 13 | 14 | include(qxtglobalshortcut5/qxt.pri) 15 | 16 | # The following define makes your compiler emit warnings if you use 17 | # any feature of Qt which as been marked as deprecated (the exact warnings 18 | # depend on your compiler).
