ZOrder 方法、文本框控件示例

下例设置文本框的 Z-顺序,使用户可以显示整个文本框(通过将其置于 Z-顺序的最前面);或者可以把文本框置于其他控件的后面(通过将其置于 Z-顺序的最后)。

窗体包含:

  • 名为 TextBox1 到 TextBox3 的三个文本框控件。
  • 名为 ToggleButton1 的切换按钮。
Sub UserForm_ToggleButton1_Click()
	If UserForm_ToggleButton1.Value = True Then
    	UserForm_TextBox2.ZOrder (fmTop)         
     	'将 TextBox2 置于 z-顺序的顶端
    	
    	'更新 ToggleButton 题注来标识下一个状态
    	UserForm_ToggleButton1.Caption = "Send TextBox2 to back"
	Else
    	UserForm_TextBox2.ZOrder (1)          
    	'将 TextBox2 置于 z-顺序的底端
    	
    	'更新 ToggleButton 题注来标识下一个状态
    	UserForm_ToggleButton1.Caption = "Bring TextBox2 to front"
	End If
End Sub

Sub UserForm_Initialize()
'建立文本框,在窗体中显示 z-order 顺序
	UserForm_TextBox1.Text = "TextBox 1"
	UserForm_TextBox2.Text = "TextBox 2"
	UserForm_TextBox3.Text = "TextBox 3"
	
	UserForm_TextBox1.Height = 40
	UserForm_TextBox2.Height = 40
	UserForm_TextBox3.Height = 40
	
	UserForm_TextBox1.Width = 60
	UserForm_TextBox2.Width = 60
	UserForm_TextBox3.Width = 60
	
	UserForm_TextBox1.Left = 10
	UserForm_TextBox1.Top = 10
	
	UserForm_TextBox2.Left = 25      '将 TextBox2 重叠于 TextBox1 上
	UserForm_TextBox2.Top = 25
	
	UserForm_TextBox3.Left = 40      '将 TextBox3 重叠于 TextBox2 和TextBox1 之上
	UserForm_TextBox3.Top = 40
	
	UserForm_ToggleButton1.Value = False
	UserForm_ToggleButton1.Caption = "Bring TextBox2 to Front"
	UserForm_ToggleButton1.Left = 10
	UserForm_ToggleButton1.Top = 90
	UserForm_ToggleButton1.Width = 50
	UserForm_ToggleButton1.Height = 50
End Sub
