如何使用C ++ Winapi（而不是MFC）创建虚拟列表视图 [英] How do I create a Virtual Listview with C++ Winapi(not MFC)

问题描述

亲爱的所有成员，



我想用C ++ Winapi（不是MFC和表单设计师等）创建虚拟列表视图控件，但我不知道真的很了解它。我已经阅读了很多教程，但我没有找到任何解决方案。

我正在使用Dev C ++



我想使用基本Windows样式编程来创建虚拟列表

用户将行和列号放到2个编辑框中，然后按创建列表按钮

这只是我的样本，而不是完整的代码（如果你需要，我当然可以发送完整的代码）

Dear All Members,

I would like to create a virtual listview control with C++ Winapi(not MFC and form designer etc.), but I don't really understand it.I've read a very lot of tutorials but I didn't find any solution.
I'm using Dev C++

I would like using the "base Windows style programming" for create Virtual List
User put the row and coloumn number to 2 editbox and after push "Create list" button
This is only my sample, not the full code(if you need, of course I can send the full code)

//WINDOW FUNCTION PROTOTYPE
LRESULT CALLBACK WndProc(HWND,UINT,WPARAM,LPARAM);
//WINMAIN
int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) 
{
 //Create the Window class and handle the message loop
}
//Window procedure
LRESULT CALLBACK WndProc(HWND Mainwindow, UINT Message, WPARAM wParam, LPARAM lParam)
{
 switch(Message)
 {
  case WM_CREATE:
  {				
   //Create button and 2 editbox
   break;	
  }
  case WM_COMMAND:
  {				
   /*If user push Button, then program read two parameters from editboxes for rows and 
     coloumns and create ListView with LVS_REPORT | LVS_OWNERDATA flag
     Setup item quantity: ListView_SetItemCount(ListView,rows*cols);
     
     Create and fill Data matrix in memory:
     
     char** matrix = new char*[rows];
     for (x=0;x<rows;x++)
	{
	  matrix[x] = new char[cols];
           for (int y=0;y<cols;y++)
	   {
             matrix[x][y]="A";
	   }
	}
     After that what should I do?Add only coloumns(LVCOLUMN structure) and handle/show 
     LVITEM structures in WM_NOTIFY?  
   */
   break;	
  }
  case WM_NOTIFY:
  {				
   //Use LVN_GETDISPINFO & LVN_ODCACHEHINT for showing only 20-30 item from data matrix
  break;	
  }
  case WM_DESTROY:
  {				
   PostQuitMessage(0);
   break;	
  }
  default:
   return DefWindowProc(Mainwindow, Message, wParam, lParam);
 }
}

如果您有任何想法，请帮助我们:)

提前谢谢！

If you get any idea, please help meee:)
Thank you in advance!

推荐答案

使用虚拟列表 [ ^ ]实际上是基于MFC，但原理是一样的。

Using virtual lists[^] is actually based on MFC, but the principles are just the same.

文档怎么样：如何使用虚拟列表 - 视图控件 [ ^ ]？

列表视图窗口样式 LVS_OWNERDATA 指定虚拟列表视图控件。

有关此列表控件样式的详细信息，请参阅关于列表视图控件。



所以从关于列表视图控件开始



http://msdn.microsoft.com/en-us/library/windows/desktop/bb774735.aspx [ ^ ]



样式LVS_LIST指定列表视图。

The List-View Window Style LVS_OWNERDATA specifies a virtual list-view control.
For more information about this list control style, see "About List-View Controls".

So start with "About List-View Controls"

http://msdn.microsoft.com/en-us/library/windows/desktop/bb774735.aspx[^]

The style LVS_LIST specifies a list view.

1. include <commctrl.h></commctrl.h>

2. link with comctl32.lib

3. Sample (Report)

#include <commctrl.h>

...

InitCommonControls();
hwndList = CreateWindow(WC_LISTVIEW, "", 
           WS_VISIBLE|WS_BORDER|WS_CHILD | LVS_REPORT | LVS_EDITLABELS, 
           10, 10, 300, 100, 
           hWnd, (HMENU)ID_LIST, hInst, 0); </commctrl.h>

（参见：http：//www.willemer.de/informatik/windows/winlistv.htm - 德语）



4.创建一个专栏

(see: http://www.willemer.de/informatik/windows/winlistv.htm - german)

4. Create a single column

int CreateColumn(HWND hwndLV, int iCol, char *Text, int iBreite)
{
LVCOLUMN lvc;

  lvc.mask = LVCF_FMT | LVCF_WIDTH | LVCF_TEXT | LVCF_SUBITEM;
  lvc.fmt = LVCFMT_LEFT;
  lvc.cx = iBreite;
  lvc.pszText = Text;  
  lvc.iSubItem = iCol;
  return ListView_InsertColumn(hwndLV, iCol, &lvc);
}

5.插入一行

5. Insert a single line

int CreateItem(HWND hwndList, char *Text)
{ 
LVITEM lvi = {0};

    lvi.mask = LVIF_TEXT;
    lvi.pszText = Text;
    return ListView_InsertItem(hwndList, &lvi);
}
