如何从SWT小部件控件（如文本）上移开焦点？

Question

I know that we can use setFocus() to set a keyboard focus on a control object such as text .

What can we do to remove the focus from the same object, reversing this function's effect?

Answer 1

You cannot remove the focus from a Control , ie unfocus it.

As @Baz suggests, you can transfer the focus to another control with setFocus() or forceFocus() . The latter gives focus to a Control even if it has the SWT.NO_FOCUS style, like Label s do.

Answer 2

You can remove/transfer focus from a SWT Control(Text) in the following 2 ways:

• Set the focus on some other Control using the setFocus() method.
• You can disable the Control widget by using setEnabled(false) method, but this will deprive the widget of its functionality. Hence it's not recommended.
