程序里面使用了浮动按钮,可以使程序看起来更美观和更容易使用。实现的方法是首先建立四条Line。和一个Image的控件,在程序根目录下把图标先改成macos.ico或者把程序相应更改一下图标文件的名字。然后代码如下:
Private Sub Form_Load() Image1.Picture = LoadPicture(App.Path & "\macos.ico")
'使Line控件不可见 Line1.Visible = False Line2.Visible = False Line3.Visible = False Line4.Visible = False
'调整Line1控件在Image1的左边,并调整大小 Line1.X1 = Image1.Left - 1 Line1.Y1 = Image1.Top - 1 Line1.X2 = Line1.X1 Line1.Y2 = Image1.Top + Image1.Height + 1
'调整Line2控件在Image1的上面,并调整大小 Line2.X1 = Image1.Left - 1 Line2.Y1 = Image1.Top - 1 Line2.X2 = Image1.Top + Image1.Height + 1 Line2.Y2 = Line1.Y1
'调整Line3控件在Image1的右边,并调整大小 Line3.X1 = Line2.X2 Line3.Y1 = Line2.Y1 Line3.X2 = Line2.X2 Line3.Y2 = Line1.Y2
'调整Line4控件在Image1的下面,并调整大小 Line4.X1 = Line1.X1 Line4.Y1 = Line1.Y2 Line4.X2 = Line2.X2 Line4.Y2 = Line1.Y2
'按钮凸起效果 Line1.BorderColor = QBColor(15) '白色 Line2.BorderColor = QBColor(15) '白色 Line3.BorderColor = QBColor(0) '黑色 Line4.BorderColor = QBColor(0) '黑色 End Sub
Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single) If Line1.Visible = True Then '防止无意义调用下列语句 Line1.Visible = False Line2.Visible = False Line3.Visible = False Line4.Visible = False Image1.Picture = LoadPicture(App.Path & "\macos.ico") End If End Sub
Private Sub Image1_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single) '左键 If Button = 1 Then Line1.BorderColor = QBColor(0) Line2.BorderColor = QBColor(0) Line3.BorderColor = QBColor(15) Line4.BorderColor = QBColor(15) End If MsgBox "Jason guo提醒你!要好好学习VB哦!!!" End Sub
Private Sub Image1_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single) If Line1.Visible = False Then '防止无意义调用下面语句 Line1.Visible = True Line2.Visible = True Line3.Visible = True Line4.Visible = True Image1.Picture = LoadPicture(App.Path & "\macos.ico") End If End Sub
Private Sub Image1_MouseUp(Button As Integer, Shift As Integer, X As Single, Y As Single) '右键 If Button = 1 Then Line1.BorderColor = QBColor(15) Line2.BorderColor = QBColor(15) Line3.BorderColor = QBColor(0) Line4.BorderColor = QBColor(0) End If End Sub
