Setting JPanel colors has no effect in the toolwindow
Answered
this.contentFactory = ContentFactory.getInstance();
this.contentManager = toolWindow.getContentManager();
JPanel jPanel = new JPanel(new BorderLayout());
JLabel jLabel = new JLabel("hi, is my chat");
jLabel.setOpaque(true);
jLabel.setBackground(Color.RED);
jPanel.setBackground(Color.RED);
jPanel.add(jLabel, BorderLayout.CENTER);
Content content = contentFactory.createContent(jPanel, "", false);
contentManager.addContent(content);

How to solve the problem of color in the desired effect? Thank you

Hi,
It is not possible to do by plugins.
Background of all components is overriden in https://github.com/JetBrains/intellij-community/blob/243/platform/platform-impl/src/com/intellij/openapi/wm/impl/ToolWindowImpl.kt . See
InternalDecoratorImpl.Companion#setBackgroundRecursively()
calls. This is an internal API, and I don't see any way of disabling this behavior by plugins.
