Java-如何在Mac中使用Command + A快捷键选择JTable中的所有行? [英] Java - How can i select all rows in JTable using Command+A shortcut in Mac?

问题描述

我的Java应用程序中有很多表.当我在Mac OS X中单击"Ctrl + A"时，它将选择当前表内的所有行.我想知道是否可以更改默认快捷方式以使用"Command + A"代替选择表中的所有行?

I have many tables in my Java application. When i click "Ctrl + A" in Mac OS X, it selects all rows inside the current table. I wonder if i can change the default shortcut to use "Command + A" instead to select all the rows in the table ?

我正在尝试在EventQueue类中执行此操作，以自动将其应用于应用程序中的所有表.

I am trying to do this inside the EventQueue class to be applied automatically on all the tables in my application.

推荐答案

Swing使用Key Bindings将KeyStrokes映射到Actions.因此，您可以添加另一个绑定以将命令A"映射到现有的控件A"绑定.

Swing uses Key Bindings to map KeyStrokes to Actions. So you can add another binding to map "Command A" to the existing "Control A" binding.

有关如何操作的更多信息，请参见键绑定.这以及How to Use Key Bindings上的Swing教程的链接.

See Key Bindings for more information on how to do this as well as a link to the Swing tutorial on How to Use Key Bindings.

是的，通常将键绑定应用于单个组件.如果要更改所有组件的绑定，则需要使用UIManager来访问默认的InputMap.对于JTable，您应该可以使用:

Yes, usually Key Bindings are applied to individual components. If you want to change bindings for all components then you need to use the UIManager to access the default InputMap. For a JTable you should be able to use:

InputMap im = (InputMap) UIManager.get("Table.ancestorInputMap");

有关显示默认InputMap的详细信息，请参见 UIManager默认值.用于每个Swing组件.

See UIManager Defaults for more information showing the default InputMap used for each Swing component.
