200分，倾囊而出。QuantumGrid 的 TdxTreeList, TdxDBGrid 各继承出一个控件（即使一行也不加）编译通过，链接出错(200分)

在CB4中， 从 DevExpress QuantumGrid （由源码在CB4编译）的 TdxTreeList, TdxDBGrid 各继承出一个控件（由Component菜单，即使一行也不加）编译通过，链接出错：

[Linker Error] Unresolved external '__fastcall Dxtl::TCustomdxTreeListControl:oDrawCell(Graphics::TCanvas *, Windows::TRect&, Dxtl::TdxTreeListNode *, int, bool, bool, bool, bool, bool, void *, System::AnsiString&, Graphics::TColor&, Graphics::TFont *, Classes::TAlignment&, bool&amp' referenced from C:/TEMPBCB/HDXTREELIST.OBJ.

加入 DevExpress 带来的lib文件到project中

问题的要点是DevExpress 的 Delphi 源程序及编译出的.hpp的函数参数类型
与CBuilder类型不匹配。造成本来是同一个函数，却被当成两个了。

This problem occurs due to the difference between Pascal and C type definitions. To be more specific the HBRUSH type in Delphi is Integer, but in Builder it is void*. The only workaround is to make changes to the header files.

Please, open the following files from your CBuilder4/Include/Vcl directory and replace all "HBRUSH" strings with "unsigned int".

dxDBGrid.hpp
dxGrClms.hpp
dxTL.hpp
dxTLClms.hpp.

You may also try to employ the following code in your projects:

#define HBRUSH unsigned int
#include ...
#include ...
#include ...
#include ...
#undef HBRUSH

接受答案了.
