Hi @bulldozier, and thanks for the pull request.

I believe that we could certainly improve on our clipboard feature and make it more convenient. I did have a quick look at your code but didn't have time to test it yet. For starters I have one request and one question:

Please provide a description for your feature here in the PR.
app/ui.js does already have a popup-message function called "showStatus()". While I didn't look into details about how your new overlay message works, I don't want to have another function doing the same thing. Could showStatus() be used instead?

CendioOssman

The principle with an automatic clipboard is nice. But there are some details that need fixing. Also:

Fix up the lint errors (see the travis build)
Could you add some tests for this?
Please try to improve the commit messages. Anyone browsing through the log should be able to quickly tell what this is about.

+    readClipboard(callback) {
+      var readfuture = navigator.clipboard.readText();


This API isn't available everywhere, so we need some handling here when it isn't.

Why not merge readClipboard() directly in to this function? It doesn't seem to be called elsewhere.

+            document.getElementById('noVNC_clipboard_text').value = text;
+            UI.rfb.clipboardPasteFrom(text);


Is this step needed? Don't we get a notification when we change the value?

CendioOssman · 2018-12-07T08:24:49Z

app/ui.js

+    copyFromLocalClipboard() {
+	UI.readClipboard(text => {
+	    var clipVal = document.getElementById('noVNC_clipboard_text').value;
+	    if ( clipVal != text ) {


I think this is essential, otherwise we have no mechanism that avoids just blindly overwriting the server clipboard whenever focus changes.

However this is still a hack, so I think we should reference the clipboardchange event and that we're waiting for browsers to implement it.

CendioOssman · 2018-12-07T08:25:35Z

app/ui.js

-        document.getElementById('noVNC_clipboard_text').value = e.detail.text;
-        Log.Debug("<< UI.clipboardReceive");
+	var curvalue = document.getElementById('noVNC_clipboard_text').value;
+	if (curvalue != e.detail.text) {


👎

We should always update the local clipboard on a proper event.

CendioOssman · 2018-12-07T08:27:22Z

app/ui.js

+	document.addEventListener('focus', UI.focusVNC);
+	document.addEventListener('focusout', UI.focusoutVNC);
+	document.addEventListener('mousemove', UI.mouseMoveVNC);
+	document.addEventListener('mousedown', UI.mouseDownVNC);


Why do we need all of these events? Isn't it sufficient with just focus?

I discovered while implementing the clipboard feature that the Chrome API clipboard.readText() is still buggy. It fails sometimes (not-deterministic why) with undefined error. When using all these events here to try to read it, it mostly works. I reported the bug to the Chrome community and suggest not implement this feature until it doesn't work properly.

That's disappointing. Do you have a link?

Yes of course, follow this: https://bugs.chromium.org/p/chromium/issues/detail?id=949926&q=clipboard&colspec=ID%20Pri%20M%20Stars%20ReleaseBlock%20Component%20Status%20Owner%20Summary%20OS%20Modified

There I described how to reproduce the bug.

Please don't hijack existing (and unrelated) event handlers.

Thanks for all the feedback. I am working on fixing all the issues. Also, I didn't actually mean to submit the pull request yet.

samhed · 2018-12-10T21:31:45Z

Hi @bulldozier no problem, I put the "Work in Progress" tag on this for now then.

It's really hard to say why that code was ever added. It just makes everything work wrong when using macos.

CendioOssman · 2019-01-11T13:49:06Z

@bulldozier, any progress?

And those commits that were added seem unrelated.

samhed · 2019-02-07T11:18:38Z

@bulldozier are you still interested in getting this merged?

bulldozier · 2019-02-07T15:37:00Z

I will eventually circle back around to this and fix a few things. The code is not ready for merge.

Hi!
We would require this feature in our project, but as @bulldozier mentioned the code is still not ready to merge. I would like to use this code base of him and make it ready to get merged into master.
How can I proceed? Should I use the forked version of @bulldozier or should I create a new clean fork from master and copy/paste the code base from @bulldozier and create a new pull request with clean messages as required?

CendioOssman · 2019-04-04T07:36:07Z

We want a clean history, so in this case I'd say to "copy" his code and finish things. Make sure to give proper attribution though, e.g. in the commit message or using multiple --author.
