So, when I have some items with html content in it, and the fx = scroll, direction = left, the first item scrolls left, the container remains empty, then quickly the second item appears.
If I use images only, one image is one scrollable item, the items follow each other smoothly, so when the first item moves left, right after the second item also comes in from the right side.
Any idea what should I set, to make the plugin work properly?
My guess is its something with the width settings of an item, but I tried several settings, no one was good.
Thank you
Maybe your item is to big for the container? or someting with position absolute/relative? Coudl you show me some of your code (and images/div sizes?)
I found the solution (in stackoverflow). I have to use float:left on the div elements I want to scroll. Now they follow nicely each other.
#subdesign,
As nicely quoted by #RunningFusion may your item be too big for the container.
Try width: "100%" instead of specifying the width in px.

I'm using Draggabilly and Packery to build a optimized draggable layout as shown in this Codepen: https://codepen.io/rafaF/pen/MWjvjqO
I have some doubts about how to use Packery/Draggabily.
The first one is how to convert en element "no-draggable", i.e., avoid to be dragged. I've achieved this by no initializing its Draggabilly instance, but I would like also to not be sorted when dragging others elements.
In the other hand, I have not been able to set a fixed height on my Packery layout in order to limit how many elements fits in a column. My idea is that if you move an element to a column that has no free space, the most bottom element should be moved to the other column. I have not found any way to do this.
There is enabled and disable switch in Draggabilly instance that you create. So just disable it if you do not need it.
The second part has to be manually solved becuase the Packery and draggabily would try to adjust in the same layout giving you best possible fit. If you want to limit the height then you have to set and run the ShiftLayout() on pakery. Ideally I would leave it to packery to determine the best layout.
I would like to see the edges of all elements in my html page. That way it is clearly visible what you are doing at any time. Currently I need to click an element to see it's bounding box, which is time consuming if you need to click a lot of elements. Is there an option I need to click to see all the bounding boxes of elements all the time?
Figured it out. You need to be in Design mode to see element boundaries.
I have a ScrollPane in my scene and would like to add a series of Nodes to it. The exact amount must be dynamic. I've been testing the concept with Label nodes and can successfully add as many Labels as I want to the content of the ScrollPane (currently a VBox).
My problem is figuring out how to allow the user to scroll normally through the ScrollPane full of Nodes. The content matches pace with the scrollbar; that is, when I scroll down, the content moves down. I scroll up, the content scrolls up. So if I have 10 Labels, only five of which are currently visible, the instinctive action to see the other five would be to scroll down. Unfortunately, this just moves the entire content down, exposing empty space up top and hiding more of the Labels.
I can post some sample code if that helps, but the gist of my plan of attack is this:
ScrollPane sp = new ScrollPane();
VBox content = new VBox();
sp.setContent(content);
for (int i = 0; i < 10; i++)
{
Label label = new Label("Label " + i);
content.setPrefHeight(content.getPrefHeight() + label.getPrefHeight());
content.getChildren().add(label);
}
Because I use a VBox, the Labels are stacked (in the Y axis) atop one another, which is what I want. As more Labels are added, the ScrollBar needs to reflect the increased size of the VBox.
I've tried a few approaches to get this to work, including ScrollPane.setVmax() method, which is ok, but I still have the issue of the scroll direction moving the content in the wrong direction. I've also tried an EventHandler and EventFilter to modify values accordingly, still without solving the problem of scrolls not moving the content in the right direction.
The answer seems so simple, yet the it continues to evade me, even after many long hours messing around with the code.
EDIT:
jewelsea's suggestion of using a ListView solved my problem. However, I remain curious as to why using a ScrollPane did not fare so well. Additionally, I've run into odd behavior with the ListView implementation: I use a button to manually add a new Label to the view. Every now and then, the view will freeze up after adding a new Label. It locks up for a few seconds before either updating the scroll position or displaying the newly added Label. I don't know if this is because there are about 20 or so Label instances being managed by the view or if something more insidious is at play.
In regards to the scrollpane issues, I know what you're looking to do is possible because I'm doing something very similar. Based on the code snippet you gave above I would suggest trying few things...
Give the ScrollPane a preferred height and width to follow.
Don't give the content VBox any height sizing preference as it will grow with its contents. There should be no need to update its height after adding content either.
Use the VBox's setAlignment method to align its contents either TOP_LEFT, TOP_CENTER, or TOP_RIGHT.
Be cautious when using the getPrefHeight() method because if you haven't used setPrefHeight() beforehand I believe it will return -1.
Hope this helps you out!
I am currently using isotope to organize my portfolio. I found that if I decided to place elements inside an isotope item and make these elements' position as fixed, they will not displace fixed on screen. Instead, these elements will use the isotope item's x and y position as the initial screen position. For instance, if I place an element as position:fixed and left:0; top:0; this element will not display on the top left corner of the screen. Instead, it will display on the top left corner of the isotope item.
Another issue I encounter is that the z-index of the element inside of the isotope item is not independent. If I give the element a greater z-index than other isotope items, say if the element has the z-index of 100, and all isotope items have the z-index of 10, the "portfolio_display" will still display behind all isotope items.
To explain what I am trying to achieve:
I want to make the isotope items become clickable, and when it is being activated, a full screen portfolio display will show up and take over the screen.
I do know plugin such as lightbox 2 will work. However, I like to have my portfolio display have much richer functions than lightbox 2. I want to put case study, images, videos, in the full screen mode, and each screen can be format like web page. So my method is to put multiple formatted divs into an isotope item, and use javescript (written by myself) to control their visibility and scrolling. This method works until I started integrate isotope to my portfolio.
I imagine isotope created a little "web page" inside of the bigger "web page" so it dictates the z-index and the position inside of its own. I like to know if I can disable isotope's dictation to its sub elements without breaking its great functionality.
Thank you.
For your full-window display purposes, you can change the modal overlay technique in this demo to your purposes. No plugin needed, you can put whatever you want to show in there, not just use it as an easy self-made modal.
I have a grid/canvas that has an element (say an icon with an image and text overlayed) added to it dynamically via code.
Most of the time it renders correctly when added (content is aligned properly inside it),
but sometimes all the content sits in one corner.
I can remove/add/remove/add/remove/add and it will eventually do it
After a movement of the parent canvas, the element corrects itself as if the layout has been updated.
I have tried the following on Loaded and OnApplyTemplate for both the element and the element parent but it still seems to happen occasionally
InvalidateMeasure()
InvalidateArrange()
UpdateLayout()
Any ideas on why the content wouldn't arrange would be appreciated cause its driving me nuts
I'm not sure why it works for you sometimes but not others. But a grid has the inherent ability to dynamically resize itself and its contents. A canvas doesn't (you'd have to handle that manually in code).
If you change your canvas to a grid does it work? A grid has slightly more overhead than a canvas but it sounds to me like you need its functionality anyway.
