I have a pane where I add labels when I scroll to the left or right. When the labels are out of sight I remove them with pane.getChildren().clear(). The problem, that I have, is the memory, that is used, is increasing to the point where the garbage collector collects the removed objects and this leads to lags in my application. I was looking for a solution and found this link https://community.oracle.com/thread/2340686. This is similar to my problem but I don't know how to unbind the child nodes from a pane. Can someone tell me how to do it? It could help to solve the memory leak in my application

I am having an issue all of a sudden when parenting a few objects just added in that they parent but appear to be a duplicate in the hierarchy under the parent and are grayed out. This is using Blender 3.0
As you can see these last 2 I parented are grayed under parent and still remain below in the collection when they were created. I have been parenting other objects (drag n drop as well as Ctrl P keeping transforms too) just fine until today and have no idea why I am getting these results?
Can someone help me understand why I am now getting these results and how to correct this issue?
TIA!

Please see my previous comment resolving my issue at least and maybe this will help others should it happen to them.
Thanks.

I am relatively new to coding on Swift and Xcode. When I was attempting to fix the design of my app, I unchecked the "Use Auto Layout" button assuming that it would simply shut off auto layout for that specific entity (An MKMapView in this situation):
Unfortunately, this removed all the constraints that I had for the entire app! I quickly tried to revert my changes by rechecking the box but it did not return to normal. Are all my constraints gone forever or is there a way to recover them?
Unfortunately, my repository is slightly out of date and I would lose a lot of work if I were to reset with the most current version saved. Any help would be amazing and really end the extreme amount of stress I just placed on myself. Thank you!
Sadly, your constraints are probably gone. Unchecking this box removes all constraints.
If you did not close and open your project since unchecking the box, you can try and undo the change, it will revert to the previous state if the conditions are ideal.
I am making a calendar app and want the ability to add multiple events to a single day. Currently, when I do this, the node stretches to fit the events. I want the whole row to stretch. Visually, this is what happens:
And this is what I want to happen:
I have done research and looked at the JavaFX API and am still unsure of how to do this. I am not asking for a code solution, just to be pointed in the right direction. Thanks.
This should solve your label problem.
yourLabelName.setMaxWidth(Double.MAX_VALUE);
We have a library bar filled with items, which can be dragged from and dropped onto it. Now the client wishes to see something like a scrollbar or arrows on the side, to have an indication if items are outside of the visible port.
As you can see in the librarybar template below, it contains a surface scrollviewer. Yet I don't seem to be able to reveal these scrollbars.
Any suggestions on how to resolve this issue?
The librarybar template:

Managed to solve it. Answer was easier then expected. Found out that the scrollbars were cleanly removed, but all properties regarding it were still present. Kind of misleading.
Easiest way to solve:
Open expression blend.
Insert SurfaceScrollViewer
Open Template from the SurfaceScrollViewer
Copy SurfaceScrollbars & necessary templates to the templates/resources
from your library bar
Adjust the templates to meet your requirements
I'm facing a pretty strange problem and I need some help from your brains :)
1) I'm using Qt 4.6.0
2) I want to enable drag&drop (Qt::MoveAction with QAbstractItemView::InternalMove only) on items in a treeview.
3) I have my own model and a proxy model used to perform some sorting...
4) Drag&Drop works well except for one single thing, here it is :
When I perform some "real quick" drag&drops in the tree (basically throwing items from a parent to another) or when I'm trying to throw an item out of the three (above the first parent, between the top parent and the treeview's viewport's limit), the moving item disappears...
Even worse, sometimes, a corrupted item is created above my first folder (See the following pictures).
Image Before
Image After
Let's try and summarize a bit :
When I perform quick and random moves with the items in the tree(changing their parents or re-placing the items in their current parent), sometimes I have items that go everywhere but where they should... I also remind you guys that when used "normally" my drag&drop works...
I hope I've been clear enough, don't hesitate to ask for further details !
Thanks in advance for your help !!
I've been having the same problem, and it seems to be because you can drop an item onto another item, and then replace that item. I haven't figured out how to solve this problem though.
