我已經在Visual Basic中創建了這個類,它工作正常,但有一個輕微的design issue。正如你可以看到有這個小笨蛋,我該如何解決這個問題?另外,如何修復內容框和選擇菜單之間的間距。自定義控件顯示問題
Public Class VerticallTabControll
Inherits TabControl
Sub New()
SetStyle(ControlStyles.AllPaintingInWmPaint Or ControlStyles.OptimizedDoubleBuffer Or ControlStyles.ResizeRedraw Or ControlStyles.UserPaint, True)
DoubleBuffered = True
SizeMode = TabSizeMode.Fixed
ItemSize = New Size(30, 170)
End Sub
Protected Overrides Sub CreateHandle()
MyBase.CreateHandle()
Alignment = TabAlignment.Left
End Sub
Protected Overrides Sub OnPaint(e As PaintEventArgs)
Dim selected As New SolidBrush(Color.FromArgb(0, 122, 204))
Dim notSelected As New SolidBrush(Color.FromArgb(63, 63, 70))
Dim B As New Bitmap(Width, Height)
Dim G As Graphics = Graphics.FromImage(B)
G.Clear(Color.FromArgb(63, 63, 70))
For i = 0 To TabCount - 1
Dim TabRectangle As Rectangle = GetTabRect(i)
If i = SelectedIndex Then
'// if tab is selected
G.FillRectangle(selected, TabRectangle)
Else
'// tab is not selected
G.FillRectangle(notSelected, TabRectangle)
End If
'Line Test
'Dim start As New Point(10, 31 * (i + 1))
'Dim ende As New Point(160, 31 * (i + 1))
'G.DrawLine(Pens.White, start, ende)
G.DrawString(TabPages(i).Text, Font, Brushes.White, TabRectangle, New StringFormat With {.Alignment = StringAlignment.Center, .LineAlignment = StringAlignment.Center})
Next
e.Graphics.DrawImage(B.Clone, 0, 0)
G.Dispose() : B.Dispose() : selected.Dispose() : notSelected.Dispose()
MyBase.OnPaint(e)
e.Dispose()
End Sub
End Class
你能澄清你由一個「bumb」是什麼意思?你不喜歡顯示器究竟是什麼? – user3697824
那麼內容和菜單高度不一樣。 – Ramog
將我添加到無法看到您要求我們解決什麼問題的用戶列表。不要調用'e.Dispose()'並使用TextRenderer.DrawText而不是DrawString。 – LarsTech
