VB.Net 表单 - MDI 表单未正确定位
我对 MDI 表单及其位置有疑问。我有一个容器表单，在其中打开多个子表单。另请注意，在容器表单中，我在顶部有一个 ToolStrip，并且它也停靠在顶部。在每个子表单中，我设置了以下属性。我也在设计时设置了它们，但由于某种原因它不起作用，所以我也将它们放在 form_load 事件中。
Me.FormBorderStyle = Windows.Forms.FormBorderStyle.None
Me.Dock = DockStyle.Fill
ReSizeAndArrange(Me.Width, Me.Height, False)
在 form_load 和 form_layout 事件上调用函数 ReSizeAndArrange。我遇到的问题是子表单没有正确填充剩余空间或整个父表单。当我单步执行时，这是我为子表单获取的坐标。
frmContainer.Size {Width = 972 Height = 972} System.Drawing.Size
me.Size {Width = 968 Height = 901} System.Drawing.Size
frmContainer.ToolStripMain.Size {Width = 954 Height = 67} System.Drawing.Size
frmContainer.Location {X = 90 Y = 22} System.Drawing.Point
me.Location {X = -9 Y = -36} System.Drawing.Point
Me.Location 不应该是 0,0 吗？这些数字加起来就是我认为的尺寸。 4 个像素的差异或许可以通过边界来解释，但具体位置却无法解释。有人能破译这个吗？
I have a problem with MDI forms and their location. I have a container form within which I open several child forms. Also note that in the container form I have a ToolStrip at the top and it is also docked to the top. In each of the child forms I have set the following properties. I have set them at design time as well but it wasn't working for some reason so I put them in the form_load event as well.
Me.FormBorderStyle = Windows.Forms.FormBorderStyle.None
Me.Dock = DockStyle.Fill
ReSizeAndArrange(Me.Width, Me.Height, False)
The function ReSizeAndArrange is called on form_load and form_layout events. The problem I am having is that the child forms do not fill the remaining space correctly or for that matter the entire parent form. When I step through, here are the coordinates I am getting for the child form.
frmContainer.Size {Width = 972 Height = 972} System.Drawing.Size
me.Size {Width = 968 Height = 901} System.Drawing.Size
frmContainer.ToolStripMain.Size {Width = 954 Height = 67} System.Drawing.Size
frmContainer.Location {X = 90 Y = 22} System.Drawing.Point
me.Location {X = -9 Y = -36} System.Drawing.Point
Shouldn't the Me.Location be 0,0? The numbers add up on the sizes I think. The 4 pixel difference can perhaps be explained by the border, however, the location is unexplained. Can anyone decipher this?

好的，我自己解决了这个问题，只需将窗体的位置设置为（0,0）即可。它仍然没有回答问题，但它是一个解决方法。
OK, I solved the problem myself simply by setting the location of the form to (0,0). It still doesn't answer the question, but it is a workaround.
这是因为 0, 0 不会对表单大小/布局施加限制。它允许它做出决定。您输入的任何值都会强制表单符合您的规格。 0, 0 不是一种解决方法，它是“你自己决定”的做法。
It's because 0, 0 doesn't put constraints on the form size/layout. It allows it to decide. Any value you put in there forces the form to conform to YOUR specs. 0, 0 isn't a work around, it's the "you decide this yourself form" way of doing it.
