I wanna achieve something like this:
It should be a shadow behind the stage, but all I could do so far is shadow elements inside it or the stage itself.
You need to create a transparent stage and on the root pane you need to add a drop shadow

I am looking for a way to draw a node on top of the neighbouring ones in a HBox. Default behaviour means it is drawn on top of the previous one, but that also means the next one is drawn on top of it. For other containers, one could use the Node.toFront(), but changing the position of the node in the list containing a HBox's children also changes the actual position in the HBox, which is unwanted behaviour in my case. I appreciate any help, thank you.
EDIT:
The overlapping occurs when applying a DropShadow effect on an Ellipse and wrapping them in a StackPane along with a Text. It looks like the effect has a weird interaction with the HBox, as it works as intended without it. After adding the effect, it allocates more horizontal space for the ellipse, but not enough to cover the margins of the effect. Also, when clicking anywhere in the whole right half of the black rectangle, the mouse click is dispatched to the stackPane event handler, not to the rectangle's.
This happens
In VBox and HBox, the Node.toFront() and Node.toBack() functions will change the layout, so they are not usable. If you are using JavaFX 9+,you can use the viewOrder commands to change the rendering order of the Node in its Parent:
Node.getViewOrder()
Node.setViewOrder()
The default value of viewOrder is 0, so setting it to -1 will render it above all others. You can customize this to get specific orders. It also has a CSS property -fx-view-order.
So, I've been programming an analog clock in JavaFX and have gotten the base functionality down. Now, I'm trying to add a drop-down menu when I click a custom button (triangle made with a Polygon). So far it all works fine, except the fact that the background of my StackPane is white when I try to add a ContextMenu either before or after clicking the button. So far Transparency has been fine up until now. Here's some pictures of the issue.
This is what it should look like (you can see my wallpaper because of the transparent window, as it should be.)

After I press the button for the drop down menu, the background changes.

JavaFX controls are styled by CSS. The first time you create a control, the default user agent stylesheet (modena.css) is loaded and the styles defined in it are applied to the scene graph. Other JavaFX node classes, such as shapes, image views, and layout panes, do not enforce CSS loading (this is to enhance performance for graphically-intensive applications that do not need CSS).
So it sounds as though the context menu is the first control you create: when you create and display it, it will apply the default CSS to the scene. The default background color for the root pane is a non-transparent color, so while your Scene and Stage may be transparent, once the CSS is applied the scene's content is not.
The fix is to specify transparency for the root pane:
root.setStyle("-fx-background-color: transparent;");
or the equivalent in an external stylesheet.
To answer my own question in case anyone else wants to know, it seems that when the ContextMenu is added to the scene, the Stage's initStyle(StageStyle.TRANSPARENT) gets overridden and shows the Parent's colors. Since I didn't initialize any CSS styles for the root, it just showed white. The fix would be to:
//the Parent layout Pane
parent.setStyle("-fx-background-color: rgba(0, 0, 0, 0.0)");
If I add a Drop Shadow Effect to a ToolBar, the ToolBar occupies more space, which is unacceptable in my case.. Is there any way to prevent the drop shadow taking extra space or ignore the mouse events on the drop shadow area? Or do I have to try another route to "add drop shadow to a toolbar"?
EDIT: setPickOnBounds(false) is a step in the right direction (I guess), but the drop shadow still consumes the events.
Well, I circumvented this by having a StackPane on top of my main content view, and adding a Region to the top of it, just below the ToolBar..
Is there a way to make the elements of a VBox smoothly move to their new positions when a new element is inserted or removed?
I actually need only to make them move smoothly when I remove an element. Thank you for your answers!
Not without extending VBox and adding your own code to do so by overriding the addChild and removeChild functions.
I'm trying to style vscrollbar and hscrollbar inside a Vbox.But there's always a white square thing at the right bottom cornor which can not be styled.
My CSS is:
ScrollBar{
downArrowUpSkin: Embed(source="assets/images/scrollbar/arrow_down.png");
downArrowOverSkin: Embed(source="assets/images/scrollbar/arrow_down.png");
downArrowDownSkin: Embed(source="assets/images/scrollbar/arrow_down.png");
upArrowUpSkin: Embed(source="assets/images/scrollbar/arrow_up.png");
upArrowOverSkin: Embed(source="assets/images/scrollbar/arrow_up.png");
upArrowDownSkin: Embed(source="assets/images/scrollbar/arrow_up.png");
thumbDownSkin: Embed(source="assets/images/scrollbar/thumb.png");
thumbUpSkin: Embed(source="assets/images/scrollbar/thumb.png");
thumbOverSkin: Embed(source="assets/images/scrollbar/thumb.png");
trackSkin:Embed(source="assets/images/scrollbar/track.png");
fillAlphas:0,0,0,0;}
Could anyone help me out?Much Thanks!
This is a weird one. The white box at the bottom right is actually a (raw) child of the container.
To get around this you need to subclass whatever container you want to add your styled scrollbars to and remove the child called "whitebox":
var whitebox:DisplayObject = rawChildren.getChildByName('whiteBox');
if (whitebox)
rawChildren.removeChild(whitebox);
IIRC you need to do the above in two places: an override of createChildren and an override of validateDisplayList. In both cases remember to call the super class method first!
That area isn't controlled by the scroll bar(s), it's part of the original container. Does the VBox have it's background colour set to black?
