JTextField 中的下拉列表 [英] drop down list within JTextField

问题描述

我知道，当我在文本字段中输入一些字母时，应该从我的数据库中选取相关项目并显示为下拉列表.例如:我在文本字段中输入了J"，在我的数据库中有诸如 {"Juby','Jaz','Jasmine','Joggy'....}论文名称应显示为列表.这样我就可以从他们中选择一个.等等，其他字母也是如此.awt 中是否有任何预定义的控件?谢谢

So that i could select one from them.and so on for other leters as well. Is there any predefined control in awt?? Thnx

推荐答案

为什么不直接使用 JComboBox?默认情况下，当用户在只读组合框中键入按键并且组合框中的项目以键入的按键开头时，组合框将选择该项目.

Why not just use a JComboBox? By default, when the user types a keystroke in a read-only combobox and an item in the combobox starts with the typed keystroke, the combobox will select that item.

或者您可以使用 setEditable(true) 将 JComboBox 设置为可编辑，并使用 KeySelectionManager.该链接解释了如何通过多次击键在 JComboBox 组件中选择一个项目.

Or you could set the JComboBox to be editable using setEditable(true), and use a KeySelectionManager. The link explains selecting an item in a JComboBox component with multiple keystrokes.
