Java RCP-无法将文本动态设置为SWT标签控件 [英] Java RCP - Not able to dynamically set text to SWT label control

问题描述

在我们的rcp应用程序窗口之一中，我需要在创建窗口后动态设置标签文本.

In one of our rcp application's window, I need to set label text dynamically after the creation of the window.

创建窗口时，我将创建标签控件，但那时我将不设置文本.用户选择窗口上的按钮后，我想在按钮的选择侦听器方法中设置标签的文本.将文本设置为按钮的选择侦听器方法中的标签后，我无法在窗口上看到文本.

When the window is created I would have created the label control but I would not set the text by then. After user selects a button on the window, I want to set the text of the label inside the button's selection listener method. After setting text to label inside button's selection listener method I am not able to see the text on the window.

当我在侦听器方法中设置标签文本时，为什么不能在窗口上看到标签文本?是因为已经创建了窗口吗?

Why is that I am not able to see the label text on the window when I set it inside the listener method? Is it because the window is already created?

我该如何解决?

推荐答案

调用 setText()后，标签的大小未得到更新.尝试在 setText()之后调用 parent.layout()，其中 parent 是包含标签控件的 Composite .

The Size of the Label is not getting updated after the call to setText(). Try calling parent.layout() after setText() where the parent is the Composite containing your label control.
