Vb.net 如何删除按钮的角?
我正在尝试删除按钮边框中未包含的角 我使用以下方法绘制按钮边框:Vb.net 如何删除按钮的角?,vb.net,button,drawing,Vb.net,Button,Drawing,我正在尝试删除按钮边框中未包含的角 我使用以下方法绘制按钮边框: Private Sub BTN_Connexion_Paint(sender As System.Object, e As System.Windows.Forms.PaintEventArgs) Handles BTN_Connexion.Paint Me.DrawRectangle(e.Graphics, New Pen(Color.White), 0, 0, BTN_Connexion.Width - 1, BTN_
Private Sub BTN_Connexion_Paint(sender As System.Object, e As System.Windows.Forms.PaintEventArgs) Handles BTN_Connexion.Paint
Me.DrawRectangle(e.Graphics, New Pen(Color.White), 0, 0, BTN_Connexion.Width - 1, BTN_Connexion.Height - 1, 10)
End Sub
Public Sub DrawRectangle(ByVal g As Graphics, ByVal pen As Pen, ByVal x As Int32, ByVal y As Int32, ByVal width As Int32, ByVal height As Int32, ByVal radius As Int32)
'Create a rectangle
Dim area As RectangleF = New RectangleF(x, y, width, height)
Dim path As Drawing2D.GraphicsPath = New Drawing2D.GraphicsPath
'Add the corners
path.AddArc(area.Left, area.Top, radius * 2, radius * 2, 180, 90) 'Upper-Left
path.AddArc(area.Right - (radius * 2), area.Top, radius * 2, radius * 2, 270, 90) 'Upper-Right
path.AddArc(area.Right - (radius * 2), area.Bottom - (radius * 2), radius * 2, radius * 2, 0, 90) 'Lower-Right
path.AddArc(area.Left, area.Bottom - (radius * 2), radius * 2, radius * 2, 90, 90) 'Lower-Left
path.CloseAllFigures()
'Draw the rounded rectangle
g.DrawPath(pen, path)
End Sub
角可以采用主颜色。这样它们就不会出现在按钮上。但我不知道这是否是一个好的做法,而且我不知道如何做到这一点
那么,您能告诉我如何删除这些角点吗?我已经解决了问题,以下是解决方案: 在要实现圆角按钮的形式中,请执行以下操作:
Private Sub BTN_Paint(sender As System.Object, e As System.Windows.Forms.PaintEventArgs) Handles BTN_Connect.Paint, BTN_Disconnect.Paint
DirectCast(sender, Button).Region = New Region(SpecificDesign.DrawRoundRectangle(0, 0, BTN_Connect.Width - 1, BTN_Connect.Height - 1, 10))
End Sub
