WPF程序员武器库图片按钮


发布日期:2022/3/3
 

一般漂亮点的软件界面都不会使用系统默认的按钮样式其中异形的图片按钮使用频率比较高

本猿不想每次需要的时候再重新写一遍或者大段的复制粘贴代码所以做了一个自定义的图片按钮控件

扩充一下自己的军火库当做常规武器方便以后使用

做之前也查了不少资料发现写XAML可以实现很多很炫的动画效果

用express工具也可以做出很炫的水晶按钮

可惜本猿是从C++到C#再转到WPF的所以上面样都不是很熟

只能用做C#winform程序的思想来实现了

按钮最多包括态的图片弹起经过按下禁用其中弹起和按下时必须的

初始化图片按钮控件的时候指定张图片的路径按钮载入图片

控件捕获其内部image控件的鼠标事件改变image的显示图片

鼠标在空间内按下然后弹起则认为是点击事件触发该控件的自定义点击事件
