我在网上找到了以下代码。 (归功于 Siri1008)
Public Function GetWordUnderMouse(ByRef Rtf As System.Windows.Forms.RichTextBox, ByVal X As Integer, ByVal Y As Integer) As String
On Error Resume Next
Dim POINT As System.Drawing.Point = New System.Drawing.Point()
Dim Pos As Integer, i As Integer, lStart As Integer, lEnd As Integer
Dim lLen As Integer, sTxt As String, sChr As String
'
POINT.X = X
POINT.Y = Y
GetWordUnderMouse = vbNullString
'
With Rtf
lLen = Len(.Text)
sTxt = .Text
Pos = Rtf.GetCharIndexFromPosition(POINT)
If Pos > 0 Then
For i = Pos To 1 Step -1
sChr = Mid(sTxt, i, 1)
If sChr = " " Or sChr = Chr(13) Or i = 1 Then
'if the starting character is vbcrlf then
'we want to chop that off
If sChr = Chr(13) Then
lStart = (i + 2)
Else
lStart = i
End If
Exit For
End If
Next i
For i = Pos To lLen
If Mid(sTxt, i, 1) = " " Or Mid(sTxt, i, 1) = Chr(13) Or i = lLen Then
lEnd = i + 1
Exit For
End If
Next i
If lEnd >= lStart Then
GetWordUnderMouse = Trim(Mid(sTxt, lStart, lEnd - lStart))
End If
End If
End With
End Function
声明一个公共变量 curWord。
然后,在 RichTextBox 的 MouseMove 事件中,将
curWord = GetWordUnderMouse(Me.RichTextBox1, e.X, e.Y)
在窗体上放置一个计时器并将其间隔设置为 2000。在计时器事件中,放置
消息框(curWord)
Me.Timer1.Enabled = False
在 RichTextBox MouseHover 事件中,启用计时器。
瞧,这个词被选中了,没有突出显示文本框。当然,如果您只是复制单词,则不需要 msgbox,但您应该能够对其进行排序。
