.NET ListView中排填充

问题描述

似乎没有要改变所有行填充（或行高）在.NET ListView中的一种方式。没有任何人有一个优雅的黑客绕？

There doesn't seem to be a way to change the padding (or row height) for all rows in a .NET ListView. Does anybody have an elegant hack-around?

推荐答案

我知道这个职位是相当老，但是，如果你没有找到最佳的选择，我有一个的，可以帮助，它涉及利用LVM_SETICONSPACING。

I know this post is fairly old, however, if you never found the best option, I've got a blog post that may help, it involves utilizing LVM_SETICONSPACING.

据我的博客，

首先，你需要添加：

using System.Runtime.InteropServices;

接下来，你需要导入的DLL，这样就可以利用SendMessage函数，修改ListView的参数。

Next, you'll need to import the DLL, so that you can utilize SendMessage, to modify the ListView parameters.

[DllImport("user32.dll")]
public static extern int SendMessage(IntPtr hWnd, int msg, IntPtr wParam, IntPtr lParam);

一旦完成，创建以下两个功能：

Once that is complete, create the following two functions:

public int MakeLong(short lowPart, short highPart)
{
    return (int)(((ushort)lowPart) | (uint)(highPart << 16));
}

public void ListViewItem_SetSpacing(ListView listview, short leftPadding, short topPadding)
{
    const int LVM_FIRST = 0x1000;
    const int LVM_SETICONSPACING = LVM_FIRST + 53;
    SendMessage(listview.Handle, LVM_SETICONSPACING, IntPtr.Zero, (IntPtr)MakeLong(leftPadding, topPadding));
}

然后使用该功能，只需通过在你的ListView，并设置值。在这个例子中，64个像素是图像宽度，并且32个像素是我的水平间距/填充，100个像素是图像高度，以及16个象素是我的垂直间距/填充，并且这两个参数需要最少的4个像素。

Then to use the function, just pass in your ListView, and set the values. In the example, 64 pixels is the image width, and 32 pixels is my horizontal spacing/padding, 100 pixels is the image height, and 16 pixels is my vertical spacing/padding, and both parameters require a minimum of 4 pixels.

ListViewItem_SetSpacing(this.listView1, 64 + 32, 100 + 16);
