TListView Header重绘和高度设置

TListView 的 Header 部分默认 BtnFace 颜色，高度也不能改变。我们可以通过编写一些代码来实现这些功能；

获得TListView 的Header 的句柄；

　　　　TListView的Header其实是一个 HeaderContorl 控件。要获得他的句柄需要调用下面的代码

//---------------------------------------------------------------------------

#include <vcl.h>

#pragma hdrstop

#include "Unit1.h"

//---------------------------------------------------------------------------

#pragma package(smart_init)

#pragma resource "*.dfm"

TForm1 *Form1;

//---------------------------------------------------------------------------

static HWND hListViewHeader = NULL;

__fastcall TForm1::TForm1(TComponent* Owner)

    : TForm(Owner)

{

}

//---------------------------------------------------------------------------

void __fastcall TForm1::FormCreate(TObject *Sender)

{

//获得ListView Header的句柄

    hListViewHeader = ListView_GetHeader(ListView1->Handle);

}

//---------------------------------------------------------------------------

其实还有许多ListView_XXXX 这样的windows API ，需要查看MSDN；

改变Header的高度

Header的高度，是在一个处理一个叫 HDM_LAYOUT 的消息的时候进行设置。

处理Header的背景色

可以在Header的窗口过程中编写WM_PAINT 消息处理函数。但是这样写，你会发现无法在Header上输出文字。准确的说，你绘制上去的文字

会莫名其妙的不见，比如，拉宽一下Header 中的某一列，文字就会消失边检。使得这种重绘不好控制；

正确的做法是这样

调用 Header_SetItem 函数（其实是一个macro）将ListView的Header 的 format 属性，设置为 HDF_OWNERDRAW (默认是 HDF_STRING).
重写ListView 的消息过程。（不是Header的消息过程）；
在ListView的消息过程中处理 WM_DRAWITEM 消息；（WM_DRAWITEM消息会包含要重绘的区域，hdc，index，状态等等）
在Header 的 HDM_LAYOUT 消息处理过程，也要调用 Header_SetItem,将format消息设置为 HDF_OWERDRAW (否则，每次改变列宽，format属性就又变成HDF_STRING,导致无法重绘)

上个版本虽然实现了效果，但是有一个bug，双击列头中间的分割区域，会导致背景色丢失；

解决办法是，

在ListView 的消息过程中，处理 WM_NOTIFY 消息
在WM_NOTIFY中处理Header发来的HDN_DIVIDERDBLCLICK 消息
WM_NOTIFY消息，一定要在默认消息处理完之后执行

LRESULT CALLBACK NewListViewWindowProc(

      HWND hwnd,

      UINT uMsg,

      WPARAM wParam,

      LPARAM lParam)

{

    if (uMsg == WM_DRAWITEM)

    {

        DRAWITEMSTRUCT* drawItemStruct = (DRAWITEMSTRUCT*)lParam;

        HDC hdc = drawItemStruct->hDC;

        int index = drawItemStruct->itemID;

        RECT rect = drawItemStruct->rcItem;

        TBrush* brush = new TBrush();

        TColor fontColor = clBlack;

        if (index == )

        {

            brush->Color = clRed;

            fontColor    = clWhite;

        }

        if (index == )

        {

            brush->Color = clYellow;

            fontColor    = clBlue;

        }

        if (index == )

        {

            brush->Color = clBlue;

            fontColor    = clWhite;

        }

        if (index == )

        {

            brush->Color = clLime;

            fontColor    = clBlue;

        }

        FillRect(hdc,&rect,brush->Handle);

        delete brush;

        SetTextColor(hdc,fontColor);

        SetBkMode(hdc,TRANSPARENT);

        //获取文本

        HDITEM hditem= {};

        char buf[] = {};

        hditem.mask = HDI_TEXT;

        hditem.pszText = buf;

        hditem.cchTextMax = ;

        Header_GetItem(hListViewHeader,index,&hditem);

        DrawText(hdc,hditem.pszText,strlen(hditem.pszText),&rect,

        DT_CENTER |DT_VCENTER |DT_SINGLELINE);

    }

    LRESULT result = oldListViewProc(hwnd,uMsg,wParam,lParam);

    //--双击列的分隔区事件

    if (uMsg == WM_NOTIFY)

    {

         NMHDR* nmhdr = (NMHDR*)lParam;

         if (nmhdr != NULL &&

             nmhdr->hwndFrom == hListViewHeader &&

             nmhdr->code == HDN_DIVIDERDBLCLICK)

         {

            //将HDF_STRING 重新设置为 HDF_OWNERDRAW

            SetHDItem();

         }

    }

    return result;

}

之后双击分隔区的效果
