CreateParams.Style的可能值是什么? [英] What are the possible values for CreateParams.Style?
问题描述
因此,我一直在尝试创建自己正在制作的AppBar程序。现在,程序本身实际上非常简单,但是我不得不从CodeProject项目中借用一些代码以使其成为AppBar。
So, I've been playing with trying to create an AppBar program I'm making. Now, the program itself is actually quite simple but I had to borrow some code from a CodeProject project to make it an AppBar.
因此,我的代码如下:
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
}
[StructLayout(LayoutKind.Sequential)]
struct RECT
{
public int left;
public int top;
public int right;
public int bottom;
}
[StructLayout(LayoutKind.Sequential)]
struct APPBARDATA
{
public int cbSize;
public IntPtr hWnd;
public int uCallbackMessage;
public int uEdge;
public RECT rc;
public IntPtr lParam;
}
enum ABMsg : int
{
ABM_NEW = 0,
ABM_REMOVE,
ABM_QUERYPOS,
ABM_SETPOS,
ABM_GETSTATE,
ABM_GETTASKBARPOS,
ABM_ACTIVATE,
ABM_GETAUTOHIDEBAR,
ABM_SETAUTOHIDEBAR,
ABM_WINDOWPOSCHANGED,
ABM_SETSTATE
}
enum ABNotify : int
{
ABN_STATECHANGE = 0,
ABN_POSCHANGED,
ABN_FULLSCREENAPP,
ABN_WINDOWARRANGE
}
enum ABEdge : int
{
ABE_LEFT = 0,
ABE_TOP,
ABE_RIGHT,
ABE_BOTTOM
}
private bool fBarRegistered = false;
private int uCallBack;
private int whereToPin;
[DllImport("SHELL32", CallingConvention = CallingConvention.StdCall)]
static extern uint SHAppBarMessage(int dwMessage, ref APPBARDATA pData);
[DllImport("USER32")]
static extern int GetSystemMetrics(int Index);
[DllImport("User32.dll", ExactSpelling = true,
CharSet = System.Runtime.InteropServices.CharSet.Auto)]
private static extern bool MoveWindow
(IntPtr hWnd, int x, int y, int cx, int cy, bool repaint);
[DllImport("User32.dll", CharSet = CharSet.Auto)]
private static extern int RegisterWindowMessage(string msg);
private void RegisterBar()
{
APPBARDATA abd = new APPBARDATA();
abd.cbSize = Marshal.SizeOf(abd);
abd.hWnd = this.Handle;
if (!fBarRegistered)
{
uCallBack = RegisterWindowMessage("AppBarMessage");
abd.uCallbackMessage = uCallBack;
uint ret = SHAppBarMessage((int)ABMsg.ABM_NEW, ref abd);
fBarRegistered = true;
ABSetPos();
}
else
{
SHAppBarMessage((int)ABMsg.ABM_REMOVE, ref abd);
fBarRegistered = false;
}
}
private void ABSetPos()
{
APPBARDATA abd = new APPBARDATA();
abd.cbSize = Marshal.SizeOf(abd);
abd.hWnd = this.Handle;
abd.uEdge = whereToPin;
if (abd.uEdge == (int)ABEdge.ABE_LEFT || abd.uEdge == (int)ABEdge.ABE_RIGHT)
{
abd.rc.top = 0;
abd.rc.bottom = SystemInformation.PrimaryMonitorSize.Height;
if (abd.uEdge == (int)ABEdge.ABE_LEFT)
{
abd.rc.left = 0;
abd.rc.right = Size.Width;
}
else
{
abd.rc.right = SystemInformation.PrimaryMonitorSize.Width;
abd.rc.left = abd.rc.right - Size.Width;
}
}
else
{
abd.rc.left = 0;
abd.rc.right = SystemInformation.PrimaryMonitorSize.Width;
if (abd.uEdge == (int)ABEdge.ABE_TOP)
{
abd.rc.top = 0;
abd.rc.bottom = Size.Height;
}
else
{
abd.rc.bottom = SystemInformation.PrimaryMonitorSize.Height;
abd.rc.top = abd.rc.bottom - Size.Height;
}
}
SHAppBarMessage((int)ABMsg.ABM_QUERYPOS, ref abd);
switch (abd.uEdge)
{
case (int)ABEdge.ABE_LEFT:
abd.rc.right = abd.rc.left + Size.Width;
break;
case (int)ABEdge.ABE_RIGHT:
abd.rc.left = abd.rc.right - Size.Width;
break;
case (int)ABEdge.ABE_TOP:
abd.rc.bottom = abd.rc.top + 100;
break;
case (int)ABEdge.ABE_BOTTOM:
abd.rc.top = abd.rc.bottom - Size.Height;
break;
}
SHAppBarMessage((int)ABMsg.ABM_SETPOS, ref abd);
MoveWindow(abd.hWnd, abd.rc.left, abd.rc.top,
abd.rc.right - abd.rc.left, abd.rc.bottom - abd.rc.top, true);
}
protected override void WndProc(ref System.Windows.Forms.Message m)
{
if (m.Msg == uCallBack)
{
switch (m.WParam.ToInt32())
{
case (int)ABNotify.ABN_POSCHANGED:
ABSetPos();
break;
}
}
base.WndProc(ref m);
}
protected override System.Windows.Forms.CreateParams CreateParams
{
get
{
CreateParams cp = base.CreateParams;
cp.Style &= (~0x00C00000); // WS_CAPTION
cp.Style &= (~0x00800000); // WS_BORDER
cp.ExStyle = 0x00000080 | 0x00000008; // WS_EX_TOOLWINDOW | WS_EX_TOPMOST
return cp;
}
}
private void button1_Click(object sender, EventArgs e)
{
whereToPin = (int)ABEdge.ABE_LEFT;
RegisterBar();
}
private void button2_Click(object sender, EventArgs e)
{
whereToPin = (int)ABEdge.ABE_RIGHT;
RegisterBar();
}
}
我的两个问题是:
什么是可能的值cp.Style以及这些值如何影响AppBar的显示? (我引用的代码位于System.Windows.Forms.CreateParams重写中)
My two questions are: What are the possible values cp.Style and how do those values effect the display of the AppBar? (The code to which I refer to is located in the System.Windows.Forms.CreateParams override)
我看到它们是诸如(〜0x00C00000)的值,但我有他们不知道它们在这些特定值之外如何工作,似乎找不到任何不同值的枚举。
I see they are values such as (~0x00C00000) but I have no idea how they work beyond those specific values and can't seem to find any enumeration of different values.
我是一个相当新的,自学成才的程序员,他通过列举示例并将其塑造成适合自己的用途而表现出色。预先感谢您可以提供的任何帮助。
I'm a rather new, self teaching, programmer who does well by taking examples and molding them to my own uses. Thanks in advance for any help you can provide.
