Pin to taskbar

[IvanRF]

Java applications do not have the ability to be pinned in the Windows taskbar, i.e. the option "Pin this program to taskbar" is not available.

There is not much info about this, I only found this: Using JNA to get/set application identifier. They use the shell32 function SetCurrentProcessExplicitAppUserModelID(WString appID) (not currently in JNA). However, that didn't work. The OP said:

The behavior you seem to be experiencing is a mode called "IsHostApp". Related

Do you have any knowledge about this? is it possible to pin a Java app with JNA?

@dblock should this be marked as "feature request"?

This is a special application feature requests. May I ask what it has to do jna? With jna you can do many things between java and native.

You answered your question 😄. This is a Windows native feature.

You answered your question 😄. This is a Windows native feature.

But it's not a problem with JNA - it's a "feature" of the Java Runtime itself, specifically the fact that java applets are all run from the java(w).exe stub.

If I remember correctly, using WinRun4J (or something like it, can't exactly remember) will allow you to pin your java window to the start bar. This is because the java app now has it's own entrypoint (exe) that calls the jvm dll - Windows will then actually recognize it as it's own application.

The fact that you can't pin applets directly launched with java(w).exe to the taskbar might be by-design - information about how to actually start the running applet may be lost in the process.

In short, I believe this is beyond the scope of JNA. If it's possible within JNA, as which your links do seem to suggest, then great. But why should there be a first-class treatment for this capability in JNA? If you want to pin your app to the task bar then you'd probably want an exe wrapper anyway.
