Java Swing：弹出：在菜单中显示小图标 [英] Java Swing: popup : display small icon in menu

问题描述

我有一个右键单击弹出菜单，工作正常。

I have a right click popup menu that works fine.

我现在想在文本旁边添加一个小图片。

I now want to add a little image next to the text.

我设法在popupmenu中显示图像，但是它是完整尺寸的版本。

I managed to display the image in the popupmenu but its the full size version.

我想知道的是：

有没有办法自动将图标大小调整为合适的尺寸（与文字相同），还是必须调整图像大小？

is there a way to automatically reize the icon to be the right size ( same as the text ) or do I have to resize the image?

推荐答案

您必须将Icon的大小调整为您想要的大小。类似于：

You have to resize the Icon to be whatever size you want it to be. Something like:

ImageIcon icon = new ImageIcon( ... );
Image image = icon.getImage().getScaledInstance(64, 64, Image.SCALE_SMOOTH);
JLabel label = new JLabel( new ImageIcon( image ) );
