Adds a delay to the group expansion #4838

johannes-manner · 2019-04-02T08:25:09Z

Adds a delay to the group expansion action. The delay is currently 1 second and only expands the group.

Is there also a need to collapse the item, if an user drags over it after a specific period?

Closes #4674

Thanks for your PR. I've only two very small suggestions for improvement before we can merge.

Please move the call to row.getTreeItem().setExpanded also to the expandGroup method (so that it does what it's name suggests).

Maybe rename to DragExpansionHandler or something like that? (because it is not really a TreeItem but some kind of wrapper)

buhtz · 2019-04-03T13:03:55Z

It is more then a "delay":

Drag one item to a closed group
Stop the mouse when the item is over the new group.
Don't move! Do nothing! Hold the mouse button (keep dragging!)
You can wait until the hell is frozen. Nothing happens. The group never expands.
Move a little bit -> then the group expands.

Second problem:
The group does not only expand it makes the complete tree scroll. When the group expands (e.g. with 12 child groups in it) the group moves away from the mouse cursor. Now the last child group is under the mouse courser.

Third problem (not quite related to that Issue):
When dragging an item on top or buttom of the tree it does not scroll. I am not able to scroll while dragging. This is also unusual.
I have no idea about Java and the libraries it offers. I would recommand to save ressources, kill the complete tree control look for a better one.

Regarding the issues reported by @noMICROSOFTbuhtz

Problem 1:
When I stop with the mouse over the new group, it will always open (so no need for me to move the mouse a little bit), BUT after one or two seconds it will close again. If you keep your mouse over the group it will continuously open and close with a period of one or two seconds. That is definitely annoying and I do not think that is intended. I reckon it should stay open, once you have waited for one or two seconds.

Problem 2:
I can confirm that the complete group expands and I see the group tree scrolling, but it has not happened to me so far, that the group of interest has moved away from the mouse cursor. So I am currently only able to replicate part of the problem (but that might be specific to how many groups/subgroups you have?).

Problem 3:
I can absolutely confirm this issue. I have reported this before here:
#2869

and I have mentioned it again here:
#4869 (comment) (last paragraph).
