Note that if this property is set to &quot; Yes &quot; (the default), this does not necessarily mean the control will really appear on the screen. Additional constraints are applied when calculating a control's effective visibility. For instance, a control placed in a hidden section in Writer will never be visible at all, until at least the section itself becomes visible.
请注意，如果此属性设置为 &quot; Yes &quot; （默认值），这并不意味着该控件实际会显示在屏幕上。在计算某个控件的有效可见性时，还会应用其他约束。例如，位于 Writer 隐藏区域中的控件在该区域自身变为可见之前将始终不可见。
