Page layout can take the scale into consideration?

What I read and experimentation little that I've done, it seems that the scale (and other transformations) on a node do not affect its layout. For example, if I set scaleX = 2 on a knot and put it in a HBox, the HBox does not give the knot twice as much space as it would otherwise.

In WPF, there are separate notions of a RenderTransform and LayoutTransform a; for the latter, containers take the transformation into account during installation on the node. Is there something comparable for JFX, or the transformations here are really only for the stuff of animation?

Use that I have in mind designs display to a fixed size components and then scaling to fit various places I put them. This is different from the automatic growth/shrinkage in that the main components of layout are good, as all would scale proportionally - sizes of fonts, line weights, etc.

As best as I can tell, if I want to apply a scale transformation to a component and arranged it properly, I would need the component that is currently scaling to lie to his mother on his size, which looks awkward. Are there better approaches?

Amy Fowler JavaFX 2.0 presentation layout is the only semi-complete treatment of JavaFX concerns of layout on the web and essential viewing for anyone who is developing JavaFX (you will simply understand why certain things happen as they do without him)-online http://www.parleys.com/#st=5&id=2734&sl=46

The answers to your questions are in two minutes slides 46 and 48 of the presentation.

The quick answer is that if you want to layout transforms, effects, etc. into account, then wrap the node to be arranged in a group.

Example of presentation of Amy:

Rectangle rect = new Rectangle(10, 10, 100, 100);
rect.setEffect(new DropShadow());
layoutRegion.getChildren().add(new Group(rect));

Note the node wrapping in a group to get the limits of effect taken into account during the pass of layout.

The relevant API that provides the information you are looking for is http://docs.oracle.com/javafx/2.0/api/javafx/scene/Node.html#boundsInParentProperty "rectangular boundaries of this node include its transformations."

Try running the following demos to help understand how the system works https://gist.github.com/1441960 and https://gist.github.com/1442298 limits

Page layout is the part the more delicate the development of JavaFX IMO, followed by Threading and deployment.

  • How can I make a feature to create a table of values of variable size, which I can take the median?

    I am new to LabVIEW all this, I know it's a simple enough question, but:

    I create a montage where we have two pressure - low pressure and high pressure sensor transducers. The problem is there is noise in the signal I want to reduce - I don't have the full version of LabVIEW (base only) so I can't use the convenient median PtbyPt.vi to reduce the noise, but I wrote something that I thought would work (attached). The question is twofold:

    (1) I don't get pressure readings when I know that the system is empty.

    (2) the change in pressure is too slow for the application in which it is used - for example atmospheric pressure reading empty takes minutes when it should take seconds. I think I could solve this problem with a business structure that analyzes the table to see if the pressure changes vary more than a certain amount. If so, do not take the median.

    Any help would be greatly appreciated!

    Go to the url that was bad, redirected to your section of custom errors, and then in the url, add? IsJava = 1, and then press ENTER. This returns the data that is located behind the page.

    One of the variables I see is called originalSiteRelativeUrl and it seems to contain information you're looking for.

    glob,

    Here are the specifications of your desktop HP Pavilion a6230n. According to the specification, this model has been on sale on or around August 10, 2007. Here is the HP Pavilion a6230n Desktop PC drivers page for your computer. Normally, there will be a link with the control HP recovery under the initially installed operating system disks. Because this model is more than 6 years, HP is no longer support this model nor maintains an inventory of recovery disc for this model. This is why you can't order from HP recovery discs.

    Please see the third party provider ComputerSurgeons.com to order recovery disc HP for your computer from HP a6230n.

  • cant edit newly downloaded pages but can change the downloaded pages, a long time ago.

    Hello

    Dreamwever CC.  IPower web.

    If I download a new page, everything is fine, but if I try to edit this page - looks that it transferred but the changes do not show on the web.
    tried clearing taken - delete all old items.  don't know how to remove broken links.

    do I need to provide more information?

    Thank you.

    As far as I know, iPower uses regularly the same as other Apache .htacess files web hosts.  No suffix.

    Maybe if it was created with your cPanel has another name, I don't know.

    The simplest thing to do is to contact your host and ask them if they are caching of the html files.

  • You can put the date into a file path?

    My program written spreadsheets. I want there to be a new file daily, entitled the days date, then the data added to the end of the day. Is any way to get the date issued by a ' get Date / Time String "and put in the path to the function"write the spreadsheet"?

    As is - anyone can confirm that a file path in a file writing worksheet is to open the file and one to come is saving and closing?

    See you soon

    Sam

    This better?

    As red Rooster have already said, use vi "string of Format Date/time" to not prevent elements of DateTime stamps that you need and also to choose appropriate delimiters.

    Keep in mind that ' / '&': ' are not allowed in Windows file names!

    Also to keep track of all your files in a folder, it is best to name your files 'Year-month-day"instead of the standard ' Monyh/day/year' (for Europeans at least ). This way you can easily find any file in a folder larger.

    You have really two different folders? One of the files before noon and the other for files after noon?

    If so keep this code.

    If not, modify this code!

  • Refresh the page layout

    Hi experts,
    I designed a layout for a page, and in this provision I displays a name (ie: output text). The page that uses this provision is to have a choice of a select to change the name and I did the background code to change the name and other details in my DB while changing the data select only one option. Changes in the complete DB, the name I posted in the page layout must take into account the change. I tried to refresh the page, it is only to refresh the page but not the layout. Can someone help me solve this problem?

  • With the help of the initial page to fill the different page layouts

    Hi all

    I am creating a form where the padding between the information on one page and then selects a specific provision, probably an option button.  When the user clicks on the button "Next" the selected schema appears and the fields are filled with the information entered on the first page.

    (1) what kind of scripts I need to achieve this?

    (2) the pages containing different page layouts are master pages?

    Thank you in advance for your help!

    Hello

    Yes you can do it.

    If your formatting is "placed", then you need to just reference the pages in the script that you want to make visible/hidden.

    If you have a layout "Flowed", and then you add objects to the sales page, LC Designer will create additional instances of this page. In the script when you reference the sales page should be visible, it will be all instances (overflow) visible.

    You cannot use the method get (core/AcroForm javascript). However, it is still pretty easy to get data from different pages.

    For example, javascript in the case to calculate an object on the sales page:

    this.rawValue = adminPage.customerName.rawValue;

    You just need to reference the object entirely.

    There is a very handy tip to insert references to objects.

    1. Select the object to which you want to enter the script in.
    2. Then highlight the object that you want to reference. Do not select it.
    3. Click in the Script Editor (at the top you will see that you are in the object you selected in step 1.
    4. Press control and hover over the object that you want to reference. The mouse turns into a 'V '.
    5. While maintaining control (the mouse pointer is a 'V'), click the object that you want to reference.
    6. LC Designer will insert the correct reference and include the reference as long as it is necessary.
    7. If you see, xfa.resolveNode in the reference, it could mean that you have not named a page or a subform, or if you have multiple objects with the same name. It is best to go back and fix that and then go through the steps above to get a clean reference.

    If you also want information to be synchronized between all three pages, you can name the same object on all three pages and in the object > range of defined binding binding to Global. In this way, regardless of what is typed in the field on three pages, will automatically be the same thing on other pages.

    Hope that helps,

    Niall

  • can open the home page but can not load other Web pages.

    I recently installed a network of a company of friends. They have a 8 computers on their network. To start connected the modem cable to router linksys n wireless and then I plugged an EZXS16W linksys 16 port switch. Everything works very well for about a month, until last week. Everything starts fine in the morning when they turn on all computers and continues for a few hours. After that, they can open their home pages (each computer has a differnet one) but when you try to view another web page, it can take up to 10 minutes, or never at all load. If I reboot the router and switch everything goes back to normal several hours then happen again. Any help would be greatly appreciated! Thank you!

  • Delete the other page layouts

    This question was one; loan requested in the forum and the only answer I could find said:

    "You can remove the other layouts in their context menu in the Pages palette and then reset your workspace:

    "Window > workspace.

    However, I don't see where in the palette Pages I can remove the provision of the replacement. Could someone please explain exactly how to do this (I created accidently a different layout I want any).

    Make sure you have chosen the Pages panel menu > display Pages > by different layout. If necessary, expand the Pages panel so you can see the other layouts. Click on the menu at the top right of the different layout and choose Remove other provision.
