'我们就以font为例,看看怎么让用户修改用户控件的属性吧 我们现在来讨论一下,怎么让用户修改font属性 请加入以下代码: Public Property Get Font() As Font Set Font = Label1.Font'将用户控件的font属性设置为控件上label1控件的font属性 End Property Public Property Set Font(ByVal New_Font As Font) Set Label1.Font = New_Font'将用户修改后的font属性赋给label1.font PropertyChanged "Font"'修改用户控件的font属性为最新的属性 End Property
ok了!用户可以在属性窗口和代码修改font了!~再添加进修改forecolor,text的属性代码,就可以完成这个用户控件了! 5. 代码全貌
现在把所有原代码都贴进来,这是一个有图片背景,支持更改text的label~ 当然之前请做好控件的属性设定: 在用户控件的界面上添加一个label一个image,同时将label1置为顶层(bring to front 反正让label1压着image1就行了) 然后将label1的backstyle设为透明,usercontrol的backstyle也设为透明,image1的strech属性设置为true,然后随便为image1添加背景图片。 接着添加如下代码: Private m_backstyle As Integer Event click() Private Sub Label1_Click() RaiseEvent click End Sub Private Sub UserControl_ReadProperties(PropBag As PropertyBag) m_backstyle = 0 Set Label1.Font = PropBag.ReadProperty("Font", Ambient.Font) Label1.ForeColor = PropBag.ReadProperty("ForeColor", &H80000008) Label1.Caption = PropBag.ReadProperty("Text", "") End Sub Private Sub UserControl_Resize() With Image1 .Left = 0 .Top = 0 .Height = UserControl.Height .Width = UserControl.Width End With With Label1 .Left = 0 .Top = 0 .Height = UserControl.Height .Width = UserControl.Width .BackStyle = 0 End With UserControl.BackStyle = 0 End Sub Private Sub UserControl_WriteProperties(PropBag As PropertyBag) Call PropBag.WriteProperty("backstyle", 0, 0) Call PropBag.WriteProperty("Font", Label1.Font, Ambient.Font) Call PropBag.WriteProperty("ForeColor", Label1.ForeColor, &H80000008) Call PropBag.WriteProperty("Text", Label1.Caption, "CMX") End Sub Public Property Get BackStyle() As Integer BackStyle = Label1.BackStyle End Property Public Property Get Font() As Font Set Font = Label1.Font End Property Public Property Set Font(ByVal New_Font As Font) Set Label1.Font = New_Font PropertyChanged "Font" End Property 'WARNING! DO NOT REMOVE OR MODIFY THE FOLLOWING COMMENTED LINES! 'MappingInfo=TextBoxEx,TextBoxEx,-1,Text Public Property Get Text() As String Text = Label1.Caption End Property Public Property Let Text(ByVal New_Text As String) Label1.Caption() = New_Text PropertyChanged "Text" End Property Public Property Get ForeColor() As OLE_COLOR ForeColor = Label1.ForeColor End Property Public Property Let ForeColor(ByVal New_ForeColor As OLE_COLOR) Label1.ForeColor() = New_ForeColor PropertyChanged "ForeColor" End Property
