一、前言在很多看图软件中,切换 图片的时候可以带上动画过渡或者切换效果,显得更人性化,其实主要还是炫一些,比如百叶窗、透明度变化、左下角飞入等,无论多少种效果,核心都是围绕QPainter来进行,将各种动画效果对应的图片的区域动态计算并绘制出来,配合以QPropertyAnimation动画属性产生线性插值,比如渐入飞入时候,可以中间快速两端慢速。目前动画类型有9种,后期还会不断增加。 * 1:图像1渐渐变淡,图像2渐渐显现 * 2:百叶窗效果 * 3:图像从右向左翻转 * 4:从外到内水平分割 * 5:图像1从左至右退出可视区域,同时图像2从左至右进入可视区域 * 6:图像1从左至右退出可视区域,同时图像2从左至右进入可视区域 * 7:图像1从下至上退出可视区域,同时图像2从下至上进入可视区域 * 8:图像1从上至下退出可视区域,同时图像2从上至下进入可视区域 * 9:图像1不动,同时图像2从右下到左上 二、实现的功能 * 1:支持多种等待样式风格 圆弧状风格 旋转圆风格 三角圆弧 线条风格 圆环风格 * 2:可设置范围值和当前值 * 3:可设置前景色背景色 * 4:可设置顺时针逆时针旋转 * 5:支持任意大小缩放 * 6:支持设置旋转速度间隔 三、效果图四、头文件代码- #ifndef IMAGEANIMATION_H

六、控件介绍 1. 超过149个精美控件,涵盖了各种仪表盘、进度条、进度球、指南针、曲线图、标尺、温度计、导航条、导航栏,flatui、高亮 按钮、滑动选择器、农历等。远超qwt集成的控件数量。 2. 每个类都可以独立成一个单独的控件,零耦合,每个控件一个头文件和一个实现文件,不依赖其他文件,方便单个控件以源码形式集成到项目中,较少代码量。qwt的控件类环环相扣,高度耦合,想要使用其中一个控件,必须包含所有的代码。 3. 全部纯Qt编写,QWidget+QPainter绘制,支持Qt4.6到 Qt5.12的任何Qt版本,支持mingw、msvc、gcc等 编译器,支持任意操作系统比如windows+linux+mac+嵌入式linux等,不乱码,可直接集成到Qt Creator中,和自带的控件一样使用,大部分效果只要设置几个属性即可,极为方便。 4. 每个控件都有一个对应的单独的包含该控件源码的DEMO,方便参考使用。同时还提供一个所有控件使用的集成的DEMO。 5. 每个控件的源代码都有详细中文注释,都按照统一设计规范编写,方便学习自定义控件的编写。 6. 每个控件默认配色和demo对应的配色都非常精美。 7. 超过130个可见控件,6个不可见控件。 8. 部分控件提供多种样式风格选择,多种指示器样式选择。 9. 所有控件自适应窗体拉伸变化。 10. 集成自定义控件属性设计器,支持拖曳设计,所见即所得,支持导入导出xml格式。 11. 自带activex控件demo,所有控件可以直接运行在ie浏览器中。 12. 集成fontawesome图形字体+阿里巴巴iconfont收藏的几百个图形字体,享受图形字体带来的乐趣。 13. 所有控件最后生成一个dll动态库文件,可以直接集成到qtcreator中拖曳设计使用。 14. 目前已经有 qml版本,后期会考虑出pyqt版本,如果用户需求量很大的话。 七、SDK下载 - SDK下载链接: https://pan.baidu.com/s/1A5Gd77kExm8Co5ckT51vvQ 提取码:877p - 下载链接中包含了各个版本的动态库文件,所有控件的头文件,使用demo,自定义控件+属性设计器。 - 自定义控件 插件开放动态库dll使用(永久免费),无任何后门和限制,请放心使用。 - 目前已提供26个版本的dll,其中包括了qt5.12.3 msvc2017 32+64 mingw 32+64 的。 - 不定期增加控件和完善控件,不定期更新SDK,欢迎各位提出建议,谢谢! - widget版本(QQ:517216493)qml版本(QQ:373955953)三峰驼(QQ:278969898)。 - 涛哥的知乎专栏 Qt进阶之路 https://zhuanlan.zhihu.com/TaoQt - 欢迎关注微信公众号【高效程序员】,C++/Python、学习方法、写作技巧、热门技术、职场发展等内容,干货多多,福利多多!
