VS2013 VB.NET窗口控件怎么做自适应
窗体在改变大小时会有一个size事件的,在这个事件中写代码获取窗体的高度和宽度再根据窗体的高度和宽度的比例来效果自己的控件的高度宽度比例
vb.net 怎样将窗体和所有控件根据电脑分辨率固定?
使用SplitContainer1控件不就行了,SplitContainer1控件的Fixedpanel属性设置为Panel1
SplitContainer1的Panel2里面再放置一个SplitContainer2
SplitContainer2控件的Fixedpanel属性设置为Panel2
二个SplitContainer设置为水平折为器方向
至于播放器控件就放在SplitContainer2控件Panel1里面
播放器控件DOCK设置为FILL
这样不管放大缩小界面,播放器控件总是自适应窗体大小而菜单按钮总是在最边缘
VB.net 控件的位置如何随窗口的变化而变化
两种方法,一种是固定窗口大小,一种是控件在窗口大小改变时,自动按窗口位置进行改变;
以上为个人看法,手打很辛苦,希望采纳,谢谢您的支持。
谢谢您的支持,有任何疑问欢迎您再次通过此渠道提问,让大家共同解决,共同进步!
以上回答仅为“百度规则”,没有任何违法行为,请楼主采纳,谢谢!
vb.net 如何使得控件随着窗体大小 的改变而改变呢,大家帮忙给想想,最好有代码的哦
Public Class Form1
Dim 初始化控件自动大小调整与窗口的宽度比例 As Integer
Dim 初始化控件自动大小调整与窗口的高度比例 As Integer
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
初始化控件自动大小调整与窗口的宽度比例 = Me.Width / 控件自动大小调整.Width
初始化控件自动大小调整与窗口的高度比例 = Me.Height / 控件自动大小调整.Height
显示控件的位置坐标()
End Sub
Private Sub Form1_ResizeEnd(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.ResizeEnd
' Form1_ResizeEnd 这个事件是 窗口大小变化完成后 再进行操作的
控件自动大小调整.Location = New Point(控件自动大小调整.Left, 控件自动大小调整.Top)
'设置控件的初始左位置坐标 与 上位置坐标
控件自动大小调整.Size = New Point(Int(Me.Width / 初始化控件自动大小调整与窗口的宽度比例), Int(Me.Height / 初始化控件自动大小调整与窗口的高度比例))
'更改控件的大小 按第一次窗口的比例 进行调整
显示控件的位置坐标()
End Sub
Private Sub 显示控件的位置坐标()
Label1.Text = "控件的上边距坐标: " 控件自动大小调整.Top
Label2.Text = "控件的左边距坐标: " 控件自动大小调整.Left
Label3.Text = "控件的宽度大小: " 控件自动大小调整.Width
Label4.Text = "控件的高度大小: " 控件自动大小调整.Height
End Sub
End Class
还有好多方法 慢慢研究吧兄弟 希望能帮到你
