How to scale components with windows javafx? - javafx-2

My windows primary pane is an AnchorPane on top of which is a TabPane, the menu of that TabPane are the tabs you see on the picture. You see the grey "background" which is part of the TabPane, when I scale my window to a bigger size, the TabPane doesn't scale with it, it stays the same size, so extra space is blank, I would like it to scale with the window, in the width of course.

You need to tell the AnchorPane to anchor its child (the TabPane) so that it is resized automatically when the window size changes.
If you are using Scene Builder you can achieve this by selecting the TabPane, going to the layout section of the properties window and setting the anchor properties.
Click on each of the dotted lines until it looks like the image below.
The same effect can also be set in code using the setXXXAnchor methods of the AnchorPane:
pane.setLeftAnchor(tabPane, 0.0);
pane.setRightAnchor(tabPane, 0.0);
pane.setTopAnchor(tabPane, 0.0);
pane.setBottomAnchor(tabPane, 0.0);

Vaadin 8 View: No horizontal scrollbar on window resizing

I have a Vaadin 8 application with several views.
public class ViewName extends Panel implements View {
There is a VerticalLayout as main layout in the panel.
public ViewName() {
setSizeFull();
VerticalLayout mainLayout = new VerticalLayout();
setContent(mainLayout);
Then I have many different layouts (HorizontalLayout, GridLayout) or Components such as Label being added as components to the mainLayout. For the HorizontalLayouts I often do the following to use the full width of the screen:
hLayout.setWidth("100%");
I have a lot of icons, grids etc. Everything is OK as long as I don't resize the window.
When I resize the window to a small size I get a mess (icons, text etc. on top of each other) and no horizontal scrollbar. (However, the grids get horizontal scrollbars.) I have tried many things to fix this. If I add
mainLayout.setSizeFull();
or
mainLayout.setWidth("100%");
I have a mess on the big screen already. I also tried the CSS for the mainLayout as described here. I get several scrollbars but none for the window itself!
The only component that resizes correctly is a Label added to the mainLayout, e.g.:
Label title = new Label("Some text",ContentMode.HTML);
title.setWidth(100, Unit.PERCENTAGE);
mainLayout.addComponent(title);
mainLayout.setComponentAlignment(title, Alignment.MIDDLE_CENTER);
I also noticed that anything in a GridLayout seems to stay in place after resizing but is not vissible since I have no scrollbar. However, icons in a HorizontalLayout get on top of each other.
What is wrong? Please, I need a general instruction on which layout I should use as main layout for my view panel, how to size the components and how to get ONE horizontal scrollbar for the main window if necessary.
The problem is that you are setting the width of your mainLayout to the width of your view. This means, that your mainLayouts width will never be bigger than your views width. So no scroll bar will appear.
According to the information you posted, changing your mainLayouts width to undefined should fix the problem.
mainLayout.setWidth("-1px");

Setting drag mode over QGraphicsScene with QGraphicsWebView() in it

I have:
self.setScene(QtGui.QGraphicsScene(self))
self.setTransformationAnchor(QtGui.QGraphicsView.AnchorUnderMouse)
self.setDragMode(QtGui.QGraphicsView.ScrollHandDrag)
where self is QGraphicsView. I am opening my svg in QGraphicsWebView() because of it's interactivity like this:
s = self.scene()
s.clear()
self.resetTransform()
self.webview = QGraphicsWebView()
self.webview.load(QtCore.QUrl(path_to_my_svg))
self.webview.setFlags(QtGui.QGraphicsItem.ItemClipsToShape)
self.webview.setCacheMode(QtGui.QGraphicsItem.NoCache)
self.webview.setZValue(0)
s.addItem(self.webview)
Zooming works fine, but when I click over webview item in order to drag it, nothing happens except cursor is changed to text cursor. I can drag svg only when I open it like self.svgItem = QtSvg.QGraphicsSvgItem(path_to_my_svg) but in that case it's rendered as static image so I lose interactivity in svg(mouseover, mouseout in svg elements)...
EDIT based on xndrme's comment:
As he suggested SHIFT+mouse left click works well, but it drags the whole SVG which is inside self.webview. Apparently I've thought that when I zoom with mouse scroll svg gets zoomed, but actually self.webview is the one that gets zoomed and scroll bars appears. So, what I've actually need to know is how to drag the whole self.webview within its scroll bar boundaries (with left mouse click)

Setting dynamic height of scrolling panel?

I have a view withing a panel with this styleCLass applied.
.scrollPanel { width:100%; height: 375px; overflow: auto;}
That panel is nested with an extension pages Application control.
I want both the height and the width of the panel set so the scroll bars of the panel appear and the browsers scroll bars are NOT activated.
This CSS works perfectly for width. I can resize my browser window and the width of the panel adjusts as needed and the browser horizontal scroll bars never come on.
But if I try 100% for height, it does not work the same. If I resize for height then the vertical scroll bars for the browser appear.
Also it would be nice to have the height of the panel always equal to the height of the available screen. With 100%, the height is very small if the view is collapsed. The height expands when the view expands. I would like for it always to be the same size percentage wise to the available height of the browser.
P.S. The set size I have of 375 works perfectly with the exception it does not resize with the browser.
Is there any way to do this?
You would need to register a window.onresize event that fetches the actual size of the window and modifies the panel accordingly, e.g. by setting its height with a style.
So the best way would be to create a method that modifies the size of your panel according to the windows size, respecting a minimum and a maximum value. Once that function is finished, you would just need to register it to the onresize event that gets fired when anything has changed the viewports display dimensions (read, a real resize or something that has enabled the windows scrollbars).
In the perfect world you would debounce/throttle the execution of this method to maybe at most every 100ms to avoid excessive CPU load during a window resize with the mouse and a window border, because depending on the browser, that event gets fired on every single pixel the mouse has moved during such a resize - which is fairly often and may lead to a slower UI response.

Horizontal button group inside anchor layout

There is a panel with anchor layout used for vertical sizing.
Inside the panel there is a horizontal buttongroup.
Is there a way to set fixed width or better make the width depend on buttons?
In my case it is always stretched to the size of the window.
There is the same problem with the grid inside the panel.
Thank you.
Making the width dependent on the buttons is handled by the layout itself. If you have an hbox layout, each of the items inside the container (say, buttons) will automatically occupy the width.

Refresh layout of dijit.layout.ContentPane

I have a dojo TabContainer that has a BorderContainer child, with a left region and a center region ContentPanes.
-TabContainer
-BorderContainer
-ContentPane (left)
-dojox.layout.ContentPane (center)
I have it setup so that the left ContentPane is collapsible (by replacing it with a slimmer ContentPane) which works fine. However, the idea of this functionality is to make the center (dojox.layout.ContentPane) region wider but when the left pane is collapsed to the slim one, the center region stays the same width.
Now I know I can call refresh() on the center ContentPane but this also refreshes the content as the center ContentPane is retrieved via href - which I don't what as it loses changes to form data.
So how do I get the center ContentPane to refresh it's layout without manually figuring out the proper width and calling resize()?
Or could you use dojox.layout.ExpandoPane. It's a ContentPane that has a 'click to minimise' ability.
how are you replacing the left pane? Are you using addChild/removeChild methods? How about just changing the widthof the left pane rather than replacing it?
