@UziTech what is the purpose of 0f7a4b7?

UziTech · 2017-09-10T19:41:32Z

@50Wliu

When trying to drag multiple files you click and hold on one of the selected files and drag to a folder.

When selecting only a single selected file when multiple are selected you just click on the selected file.

We need to make sure the user is not dragging before deselecting all files except for the one that is clicked on. In order to do that we need to do the deselect on mouseup.

We still want most mouse operations to occur on mousedown. Only when we need to make sure there is no dragging do we do the operation on mouseup.

Ben3eeE · 2017-09-16T20:56:12Z

I'm signing up for testing here since I tested the original PR.

andyfleming · 2017-09-23T22:21:03Z

Great work! Let's get this done!

I can't believe we can't drag multiple files in atom yet 😆 .

UziTech · 2017-10-06T18:19:13Z

@Ben3eeE anything holding this up?

Ben3eeE · 2017-10-06T20:10:31Z

@UziTech Sorry been swamped with other things. I will take a look as soon as I get a chance to, hopefully I will have some time this weekend ⚡️

UziTech · 2017-10-19T18:32:40Z

I rebased again and fixed the merge conflicts in the tests

UziTech · 2017-10-27T13:40:02Z

@Ben3eeE Any way we can get this out the door so I don't have to keep rebasing?

arthurlacoste · 2017-11-08T18:29:44Z

Please, merge this feature !

When a directory and its children are being dragged, only drag the directory, not the individual children.

this test guarantees that dragging a directory d and additional files f into a new directory will move the entire directory d discreetly along with any additional files f.

re-enable a metaclick to allow an item to be selected from the multi-selection. change the behavior of drag image building so that there's no collapsing and properly deselects the drag image.

UziTech · 2018-01-29T15:23:02Z

I believe I fixed the issue where a folder would get deselected when dragging over it with files from another Atom window.

I added the class drag-over as well as selected so themes still highlight the folder but only remove the selected class on leave if it also has the drag-over class

@Ben3eeE I manually tested all of those cases on a Windows 10 and they seem to work as expected. One other case I came across that doesn't work but probably should is dropping a selection on a file. I would expect that the selection would be moved into the same folder as the file that is being dropped on, but right now the move operation is just canceled when dropping on a file.

Tested this quick and it appears to also be an issue on master so it's not going to block this PR from moving forward. Do you want to create an issue for this?

UziTech · 2018-01-29T15:49:25Z

I just added it to this pr

winstliu · 2018-01-29T22:12:26Z


    entryName = path.basename(initialPath)
-    newPath = "#{newDirectoryPath}/#{entryName}".replace(/\s+$/, '')
+    newPath = "#{newDirectoryPath}#{path.sep}#{entryName}".replace(/\s+$/, '')


Nit: could you remove this change and add it in a separate PR? It should also be path.join(newDirectoryPath, entryName).

I ask because I'm also fixing this same line in both #1180 and #1173, so it would probably be better to just submit this change in a different PR.

winstliu · 2018-01-29T22:13:31Z

-        return
+    e.stopPropagation()
+
+    # TODO: meta+click and ctrl+click should not do the same thing on Windows.


Is fixing this something that would require a significant rework of the specs?

Yes. Any spec that simulates a [ctrl] + [click] on windows, does so by setting e.metaKey to true.

It is also not that big of a deal because in Windows meta(Windows key)+click isn't something people usually do.

winstliu · 2018-01-29T22:14:34Z

-        @selectMultipleEntries(entryToSelect)
+    # return early if clicking on a selected entry
+    if entryToSelect.classList.contains('selected')



🔥 blank line

winstliu · 2018-01-29T22:19:27Z

    @roots = []
    @selectedPath = null
+    @selectOnMouseUp = null
+    @lastFocusedElement = null


Seems like this makes more sense as @lastFocusedEntry?

winstliu · 2018-01-29T22:21:55Z

    @list.classList.remove('full-menu')
    @list.classList.add('multi-select')

+  toggleMultiSelectMenu: ->


toggle generally implies "if on, turn off (and vice versa)". Therefore a better name for this method might be showMultiSelectMenuIfNecessary.

winstliu · 2018-01-29T22:23:35Z

+          newElement.style.paddingRight = "1em"
+          dragImage.append(newElement)
+
+


🔥 extra empty line

winstliu · 2018-01-29T22:34:02Z

Going back to your comment here: #1179 (comment)

Perhaps click could be used to combine the two cases?

UziTech · 2018-01-29T23:07:21Z

I could use click but I would still need a variable letting the onClick function know if it should execute otherwise it would deselect a file after selecting it on mousedown. And we do want to use the mousedown function for selecting because someone might want to ctrl+click then just start dragging.

adamreisnz · 2018-02-03T03:13:11Z

Would be great to have this 👍

winstliu · 2018-02-03T03:23:17Z

Code changes look good to me. @Ben3eeE if you're good with this as well I think it can 🚢?

Ben3eeE · 2018-02-06T19:19:01Z

@UziTech All good from me when testing on Windows 👍 @ungb is going to go over the test plan on macOS and Linux and merge if all is good.

ungb · 2018-02-06T21:32:30Z

I'm looking into this now. going off test plan in #1179 (comment). I'll merge this once I'm done

ungb · 2018-02-07T04:49:17Z

I ran into the following while dragging between two atom windows.

See gif for repro.

Repro steps:
Run the following command to create the folders and file

mkdir test1 test2
cd test1 && touch a b c && cd ../test2 && touch a b c && cd ..
atom test1 && atom test2

Drag file a from folder test1 to folder test2 in the other atom window

Atom: 1.23.3 x64
Electron: 1.6.15
OS: Mac OS X 10.12.6
Thrown From: tree-view package 0.222.0

Nice catch

ungb · 2018-02-07T18:42:08Z

Ctrl+click doesn't work on linux.. it seems to just open up the context menu. Shift works fine.

@Ben3eeE does this work on windows? I can spend some time testing windows today as well.

After the latest change, everything works great on mac!

Ben3eeE · 2018-02-07T19:47:55Z

@Ben3eeE does this work on windows?

@ungb It did when I tested. I have not tested on the most recent commit however.

ungb · 2018-02-09T01:58:51Z

@Ben3eeE I think my issues is because I'm running on a VM on mac and it's doing something weird. I'll take a look when I get home on my windows machine and then try to see if I spin up a VM on there for linux. So far everything looks good, but every time I hit ctrl+click it opens up the context menu. I'm noticing this on my VM and happens on the desktop on windows too.

Ben3eeE · 2018-02-09T09:07:54Z

@ungb I have Ubuntu installed so I can test this on Linux if you run into more issues because of testing in a VM.

ungb · 2018-02-10T07:15:57Z

I've tested this and everything looks good to me. I'm going to merge this. I'm going to follow up with the team later on the appveyor failure so we can get this into master.

UziTech · 2018-02-10T07:35:08Z

jonathan-dejong · 2018-05-08T13:51:11Z

Any news on this?
From what I can tell with Atom 1.26.1 it is not merged yet.

Ben3eeE · 2018-05-08T14:17:12Z

@jonathan-dejong This is merged but it's not released yet because the tests are failing on atom/atom when upgrading the tree-view. You may want to subscribe to atom/atom#17088 for updates on when it will be available in a released version of Atom.
