c# - 如何更改ToolStripButton的光标？

当用户将鼠标悬停在特定的ToolStripButton上时，我想更改其光标，但不在ToolStrip上的其他项目上更改。如何设置按钮的光标？

最佳答案

因为ToolStripItem不继承自Control，所以它没有Cursor属性。

您可以在MouseEnter事件上设置表单光标，并在MouseLeave事件上恢复表单光标，VB示例如下：

Dim savedCursor As Windows.Forms.Cursor

Private Sub ToolStripButton1_MouseEnter(ByVal sender As Object, ByVal e As System.EventArgs) Handles ToolStripButton1.MouseEnter
    If savedCursor Is Nothing Then
        savedCursor = Me.Cursor
        Me.Cursor = Cursors.UpArrow
    End If
End Sub

Private Sub ToolStripButton1_MouseLeave(ByVal sender As Object, ByVal e As System.EventArgs) Handles ToolStripButton1.MouseLeave
    Me.Cursor = savedCursor
    savedCursor = Nothing
End Sub

更新资料

这是C＃中的相同答案：

private Cursor savedCursor;

private void ToolStripButton1_MouseEnter(object sender, EventArgs e) {
    if (savedCursor == null) {
        savedCursor = this.Cursor;
        this.Cursor = Cursors.UpArrow;
    }
}

private void ToolStripButton1_MouseLeave(object sender, EventArgs e) {
    this.Cursor = savedCursor;
    savedCursor = null;
}
