Pull the state of this PR
Run ideasy with a Run Config that runs ide gui
You now should be able to see a status text in the bottom right corner, saying "IDEasy is ready."
Ensure, that at least two of the IDEs shown in the GUI is NOT installed on your system/project.
With the IDE that is not installed, click on "Open". Now you should see a progress bar in the bottom right corner and the download progress on the label.
When downloading two IDEs at the same time, you should see a "2 tasks running..." status that allows you to click the status text, opening a window with a list of all running tasks.

- Added testing class for modals

- Added logging to IdeGuiStateManager. - Added functionality, that selecting a different project now switches the IdeContext to the new project.

Great job, the progress bars are a really nice addition. They give the user clear feedback instead of just waiting without knowing what is happening 👍I left a few notices.

KarimALotfy · 2026-06-17T14:36:14Z

I am not sure if this only happens on my side, but the progress bars were only shown when I started the GUI via AppLauncher, not when using the gui commandlet.

Oh ok! Good to know! Did you see something like a status text? Maybe let's take this out of the release then.

laim2003 · 2026-06-17T18:48:56Z

I also figured that it seems like sometimes things that work via AppLauncher don't work when launched via the Commandlet...

KarimALotfy · 2026-06-17T21:30:53Z

Small suggestion: I noticed that the task window stays open even after multiple tasks are finished.

Once the IDE(s) are downloaded, extracted, and launched successfully, it would be nice if the task/progress window closed automatically.

laim2003 · 2026-06-18T12:59:45Z

@KarimALotfy i think i might know, why you didnt get the progress bars when launching via ide gui. You have to manually upgrade ide to the latest snapshot before following the test steps, because otherwise, the Gui Commandlet will request an old (stable) version of the GUI from the maven central repository (Because the Gui Commandlet uses a pom.xml that always uses the current IDEasy version that is installed on the system). Therefore, you most likely didnt get the latest snapshot GUI jar, so you also did not have the progress bars. Also explains why they were there when you executed the AppLauncher.

+          System.out.println("Uncaught exception in thread " + thread.getName() + ":" + throwable.getMessage());
+
+          //Left this in, because of issues with printing errors when the Fx Application Thread crashes. Needs further research.
+          throwable.printStackTrace();


I already have this in my PR #2027, wrapping the start method logic in a try-catch would allow startup errors to be caught and shown properly in the dialog

Can't we use proper logging (SLF4J)?
Calling printStackTrace() (and also System.out) directly is typically discouraged.

KarimALotfy · 2026-06-17T15:24:33Z

+    this.guiStateManager = guiStateManager;
+    this.projectManager = guiStateManager.getProjectManager();
+
+    ListChangeListener<ProgressBarTask> taskListChangeListener = change -> {


Small suggestion: Maybe we could extract this listener setup into a separate method to improve readability
