效果截图
先看软件运行效果截图,然后接下来讲解使用:

目标:
本示例讲解炫彩阴影窗口的使用, 让读者可以利用炫彩界面库轻松实现阴影功能;

说明:
本示例使用炫彩界面库提供的窗口阴影功能实现,可设置阴影的大小,深度,角大小,是否强制角为直角,及阴影的颜色;
调用该函数XWnd_SetTransparentType()设置窗口为阴影窗口,窗口被修改为分层窗口,因为只有分层样式的窗口才可以透明;
调用该函数XWnd_SetShadowInfo()设置阴影的效果;
如果想设置窗口整体的透明度,可调用该函数XWnd_SetTransparentAlpha();

此示例中我创建了几个滑动条,方便大家通过拖动滑动条,动态调整参数,预览效果;
一个多选按钮, 可以设置是否强制为直角;
一个颜色编辑,可设置阴影的颜色;

主要用到的函数:

XC_API void WINAPI XWnd_SetShadowInfo(HWINDOW hWindow,int nSize, int nDepth, int nAngeleSize,BOOL bRightAngle,COLORREF color);

该函数设置阴影的效果,

参数说明:
hWindow 窗口句柄.
nSize 阴影大小
nDepth 阴影深度,0-255.
nAngeleSize 圆角阴影内收大小.
bRightAngle 是否强制直角.
color 阴影颜色.

XC_API void WINAPI XWnd_SetTransparentAlpha(HWINDOW hWindow,BYTE alpha);

此函数可设置窗口整体的透明度;
