制作VB另類按鈕

領測軟件測試網 　　如果你看膩了VB的中規中矩的按鈕，有時想改變一下的話，本文或許對你有所啟發。以下二例用Line方法結合其它手段，在窗體上繪制出別具一格的“按鈕”，呵呵，還是有那么一點兒新意的(怎么象是吹牛？)。建議在不需要太多的按鈕的窗體中使用。

例一：用Line方法制作初始時為平面、鼠標移到時突出的按鈕，此類按鈕其實更象是第一層菜單，可為之通過Form_MouseDown或者Form_MouseUp編寫類似于Click的事件。當然了，用標簽+線條或者+ImageBox來實現更簡單些。

Private Sub Form_Load()

Me.AutoRedraw = True
CurrentX = 280: CurrentY = 150
Me.Print "Exit"
Me.Caption = "請將鼠標移近文字觀察效果"
End Sub

Private Sub Form_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
If Button = 1 Then
If X <= 900 And X >= 100 And Y <= 500 And Y >= 100 Then
End
End If
End If
End Sub

Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)

If X <= 900 And X >= 100 And Y <= 500 And Y >= 100 Then
Me.Caption = "左鍵單擊按鈕退出程序"
Line (100, 100)-(100, 400), vbWhite
Line (100, 100)-(800, 100), vbWhite
Line (100, 400)-(800, 400), vbBlack
Line (800, 100)-(800, 425), vbBlack '多出25是為了讓右下角更封閉
Me.ForeColor = vbBlue
CurrentX = 280: CurrentY = 150
Me.Print "Exit"
Else
Me.Cls
CurrentX = 280: CurrentY = 150
Me.ForeColor = vbBlack
Me.Print "Exit"
Me.Caption = "請將鼠標移近文字觀察效果"
End If

End Sub

例二：用Line方法結合PictureBox(作按鈕容器用)制作有立體感的按鈕，很Cool喲。要試用本例，請在窗體上缺省繪制一個1000*700的PictureBox控件。

Private Sub Form_Load()

Dim k As Integer
Picture1.AutoRedraw = True
Me.AutoRedraw = True

'繪制出灰度的效果
For k = 0 To 20
Rect Picture1, 5 * k, 5 * k, Picture1.ScaleWidth - 10 * k, Picture1.ScaleHeight - 10 * k, RGB(255 - 5 * k, 255 - 5 * k, 255 - 5 * k)
Next k

Picture1.CurrentX = 250: Picture1.CurrentY = 250
Picture1.Print "Hello"

End Sub

'繪制矩形
Sub Rect(obj As Object, X As Integer, Y As Integer, iW As Integer, iH As Integer, iC As Long)
obj.Line (X, Y)-(X + iW, Y), iC
obj.Line -Step(0, iH), iC
obj.Line -Step(-iW, 0), iC
obj.Line -Step(0, -iH), iC
End Sub

'鼠標在窗體移動時按鈕保持灰度的原貌
Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
For k = 0 To 20
Rect Picture1, 5 * k, 5 * k, Picture1.ScaleWidth - 10 * k, Picture1.ScaleHeight - 10 * k, RGB(255 - 5 * k, 255 - 5 * k, 255 - 5 * k)
Picture1.ForeColor = vbBlack
Picture1.CurrentX = 250: Picture1.CurrentY = 250
Picture1.FontBold = False
Picture1.Print "Hello"
Next k
End Sub

'鼠標移動到圖片框時按鈕形狀發生變化:底色為深色，按鈕周邊帶色彩邊框，文字變色
Private Sub Picture1_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
Dim k As Integer
For k = 0 To 20
Rect Picture1, 5 * k, 5 * k, Picture1.ScaleWidth - 10 * k, Picture1.ScaleHeight - 10 * k, RGB(8 * k, 12 * k, 8 * k)
Picture1.ForeColor = vbRed
Picture1.CurrentX = 250: Picture1.CurrentY = 250
Picture1.Print "Hello"
Next
End Sub
