C语言编写的界面使用扁平滚动条vcb.cc-优快云博客

vcb.cc网站中找到一个demo，写在这里记录一下。

今天收集到的例子:

不知道用吗?

用于显示一个扁平的滚动条.

过 Windows API 钩子和自定义绘制实现：

powerbuilder

// 声明 API 函数
Function Long InitializeFlatSB(Long hwnd) Library "comctl32.dll" Alias For "InitializeFlatSB"
Function Long UninitializeFlatSB(Long hwnd) Library "comctl32.dll" Alias For "UninitializeFlatSB"
Function Long FlatSB_SetScrollProp(Long hwnd, Long index, Long newValue, Long bRedraw) Library "comctl32.dll" Alias For "FlatSB_SetScrollProp"

// 常量定义
Constant Long WS_HSCROLL = 1048576  // 0x00100000
Constant Long WS_VSCROLL = 2097152  // 0x00200000
Constant Long WSB_PROP_CYVSCROLL = 2
Constant Long WSB_PROP_CXHSCROLL = 4
Constant Long WSB_PROP_CYHTHUMB = 10
Constant Long WSB_PROP_PALETTE = 7

// 启用扁平滚动条
Long ll_handle
ll_handle = Handle(w_main)

// 初始化扁平滚动条
InitializeFlatSB(ll_handle)

// 设置滚动条属性
FlatSB_SetScrollProp(ll_handle, WSB_PROP_PALETTE, 0, True)  // 使用默认配色
