VB.NET如何右击ListBoxx选择文件?
这回没分不写代码,哈哈......
利用listbox的MouseDown事件获取当前是哪个鼠标按键点击了控件;
通过MouseEventArgs事件类的Location属性获取鼠标在listbox中的坐标;
通过listbox的行高来计算鼠标在listbox的哪一行;
通过listbox的SelectedIndex属性来选定鼠标所在的那一行。
PS:算了,好人做到底吧!
Private Sub ListBox1_MouseDown(sender As Object, e As MouseEventArgs) _
Handles ListBox1.MouseDown
If e.Button = Windows.Forms.MouseButtons.Right Then
Dim ht As Integer = ListBox1.ItemHeight
Dim rect As New Rectangle _
(0, 0, ListBox1.ClientSize.Width, ht)
For i As Integer = 0 To ListBox1.Items.Count - 1
If rect.Contains(e.Location) Then
ListBox1.SelectedIndex = i
Exit For
Else
rect.Y += ht
End If
Next
End If
End Sub
vb.net,我有一个鼠标右键点击的事件,我想在这个事件里面加入鼠标左键点击的动作,
你已经有了“鼠标右键点击的事件”
说明你肯定已经有了if e.button=windows.forms.mousebuttons.right then
你只需要找到这条语句,通常这句话应该在你的mouseclick事件中。
这条语句改成
if e.button=windows.forms.mousebuttons.left or e.button=windows.forms.mousebuttons.right then
就可以了!
