GUI Elements enable / disable

What API are you using here? Could you please share a code snippet?

Hi Yann,

It's classic JButton:

import javax.swing.*;
import java.awt.*;

var hcpy = new JButton();
hcpy.setOpaque(false);
hcpy.setContentAreaFilled(false);
hcpy.setBorderPainted(false);
hcpy.setEnabled(false);

Why don't you use this API https://plugins.jetbrains.com/docs/intellij/basic-action-system.html#building-ui-from-actions?

Well, I could, but at this stage I want to avoid big changes in the code, the project is in the maintain phase. There must be a reason why this stopped working in 2023.3. Maybe the New UI? What could I do to get this working with the JButton?

What happens if you disable New UI in 2023.3? Could you please share your sources or the plugin for reproducing?

Hi Yann,

with disabled New UI  the behavior is the same. I did couple of tests, and found out, that the JButton's text is correctly disabled. Only the icon always has the ‘enabled' appearance.

You can install the plugin from here: https://plugins.jetbrains.com/plugin/19828-rohde--schwarz-instrument-connectivity

However, you'd need a measurement instrument that supports VISA interface to test this. Therefore, to reproduce it, I created a simple plugin with one ToolWindow, JPanel as content with one disabled JButton - text and icon. You can see from the picture, that the text is disabled, but the icon looks enabled:

Here's the code for InstrumentsListToolWindowFactory.java :

package com.rohdeschwarz.ic;

import com.intellij.icons.AllIcons;
import com.intellij.openapi.project.DumbAware;
import com.intellij.openapi.project.Project;
import com.intellij.openapi.wm.ToolWindow;
import com.intellij.openapi.wm.ToolWindowFactory;
import com.intellij.ui.content.ContentFactory;
import org.jetbrains.annotations.NotNull;

import javax.swing.*;

public class InstrumentsListToolWindowFactory implements ToolWindowFactory, DumbAware
{
    /**
     * Create the tool window content.
     */
    @Override
    public void createToolWindowContent(@NotNull Project project, @NotNull ToolWindow toolWindow)
    {
        var pnl = new JPanel();
        var bt = new JButton("MyDisabledButton", AllIcons.Actions.Refresh);
        bt.setEnabled(false);
        pnl.add(bt);

        var contentFactory = ContentFactory.getInstance();
        var content = contentFactory.createContent(pnl, "", false);
        toolWindow.getContentManager().addContent(content);
        toolWindow.setIcon(AllIcons.Toolwindows.Documentation);
    }
}

Hope you can help to resolve this
