在SWT中使用组合框的WidgetProperties.SingleSelectionIndex（）

[英]Use of WidgetProperties.SingleSelectionIndex() of Combo box in SWT

原文 2015-12-09 17:01:58 4 1 java/ combobox/ swt

Can anyone explain the use of the WidgetProperties.singleSelectionIndex().observe(combo) ? 谁能解释WidgetProperties.singleSelectionIndex().observe(combo)的用法？

I have read the API documentation for it. 我已经阅读了API文档。 But I could not get a clear idea about it. 但是我对此不清楚。

This observes the value of the Combo getSelectionIndex value (and set with select(index) ). 这将观察Combo getSelectionIndex值的值（并使用select(index) ）。 This is the index of the currently item in the Combo items. 这是组合项中当前项的索引。 You would only use this with a read only Combo. 您只能将其与只读Combo一起使用。
