Question of simple layout, decrease of the TextField and TextArea in VBox
Given: VBox root = new VBox(10);
root.getChildren().addAll(new TextField(), new TextArea());
Scene scene = new Scene(root, 300, 250);
When I minimize the window of application vertically, textfield begins to shrink in the first place, while the text box remains its size, then when the TextField is a narrow strip, the text box begins to shrink.(1) is it planned?
(2) it is design? If so, why?
(3) how can I avoid, i.e. have the text box to shrink first, then the TextField?
He thinks that the behavior in 3) makes more sense, since by its very nature, a text box can have different heights; a field of text on the other hand, I expect to have the height of one line of text, unless there is absolutely no space for him in its container. It is not supposed to have a textfield that is a fraction of the height of a line of text.
I tried various combinations of minHeight and prefHeight, but without success.
Hey,.
(1) Yes, it's expected!
(2) Yes, why... Well I don't know why the minimum height of a TextField is less than the size of pref.
(3) this can be avoided by defining your own sizes (min size - pref - max size)
VBox root = new VBox(10);
root.setStyle("-fx-background-color: lightgray");
TextField tf = new TextField();
tf.setMinHeight(Control.USE_PREF_SIZE); //the minimum height = the preferred height
TextArea ta = new TextArea();
ta.setMinHeight(30);
ta.setPrefHeight(50);
ta.setMaxHeight(Double.MAX_VALUE); //maximum height, depends on the parent
VBox.setVgrow(ta, Priority.ALWAYS); //use the maximum height available
root.getChildren().addAll(tf, ta);
Scene scene = new Scene(root, 300, 250);

Mr President
Buy a laptop the year last Dell with VISTA. It won't let me partition (including shrinkage etc.). No matter where you go that it denied access, including loading the program. Search function I'm trying to understand for a year yet, I can't find.
I want to explore the "Document and Settings", but access is denied.
Finally, I gave up on VISTA now that I bought a XP Pro... Tried to format the drive it did not show me the hard drive.
Direct booting from cd said that it found no hard drive to load. I am just desperate and sick of this VISTA. Please help to get rid of this OS.
I'll be eternally grateful to you if you can help me. The newest...

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Come on first, site of the manufacturer of your computer, check to see if your model computer has XP drivers available for it...
If the XP drivers are not available for your model, forget the idea.
If Yes, download and save to a CD or Flash drive.
Save all your data because it will be lost during the installation of XP.
Then follow the steps below to do a clean install.
Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.
At the startup/power on you should see at the bottom of the screen either F2 or DELETE, go to Setup/Bios or F12 for the Boot Menu

Maps and layouts: update of the failure or will not erase
Select Page layouts et Cards fail to update correctly. This is the case for the unreleased updates to with no associated collection and the unreleased cards with associated No. layouts. In addition, in some cases published layouts or maps indicate the status ""update failed, obsolete, "but the changes make their way to the app." This happens for some layouts and cards, but not all; In addition, some layouts and cards work fine for awhile and then fail to publish or will not erase. Is this a known issue? [using publish.adobe.com app 2015.2.100 version]
Hey Kristen - Sounds complicated, and I don't know all the details completely, but I have had similar experiences and started to notice the following, especially with the cards and layouts.
Scenario:
I have a card and use it in a mapping rule for a layout. Everything is cool, work the way you want.
Now, I want to remove the card (I am resetting things for a demo session and want to start without cards nor the updates page with the exception of the default values.)
If I delete the card first, I get the message "Failed to update, obsolete".
To avoid this or delete it, I need to remove all mapping rules in all page layouts that call the map and publish all these layouts (without the map reference.)
So I new and remove the card.
I followed a similar procedure for the removal of the page layouts-
The value of all the collections so that none use the layout to remove
Publish all the collections that are obsolete.
Then you can new and remove the unwanted provision.
It's probably pretty fussy, but it works.
I've had similar experiences with items and collections. If an article or a collection is used in several collections, I would get a similar error. I had to work on what article or the collection has been used in several places before I could new and delete.
Hope that helps

cannot change the date and time in the system restore
How can I change the date and time in the system restore? When I try to create a new restore point, I can't change the date and time, the system automatically date and time in.
System Restore will always set the date and time of any restore point created at the effective date and time of the machine.
If you want to restore your computer to a date and an hour earlier, you must select restore from a restore point that was created at the earlier time. This article explains how.
With the help of the Windows Vista system restore
http://www.howtogeek.com/HOWTO/Windows-Vista/using-Windows-Vista-system-restore/My apologies if I misunderstood your question. Why should change you the date and time when a restore point was created? The only possibility of achieving a fictitious date and time will result in a change as actual date and time Windows or in the Bios, either option with unforeseen consequences.

BlackBerry Z10 updated the phone and now remove contact does not work
Hi all
I just rec'd blackberryz10 and I did an update yesterday. I now have a problem I did not before.

Any HELP or ADVICE would be greatly appreciated.

Hey lquon,
Welcome to the community of BlackBerry Support Forums.
Thanks for the question.
In Contacts, drag the top and choose settings. Once in the settings, how many accounts is enabled? If there are several service accounts, change all except your e-mail account and then let me know if the duplicates appear always.
I look forward to your reply.

Get the height and width of an image
I have therefore some images in my program that I'm loading. These images are much longer than the size of the screen. So I put in a ScrollView. My question is how can I get the height and width of an image. The image.width and image.height doesn't return the correct values.
//add the image private function addImage():Container { var sp1:Container = new Container(); sp1.sizeUnit = SizeUnit.PIXELS; sp1.debugColor = 0xFFFFFF; sp1.margins = Vector.
([1,0,0,0]); sp1.align =ContainerAlign.NEAR; //sp1.setSize(650, 800); var myPattern:RegExp = / /g; var fileName:String = "./com/swiz/img1.png"; var icon:Image = new Image(); icon.setImage(File.applicationDirectory.resolvePath(fileName).url); //icon.setPosition(0,0); //icon.setSize(320,800); sp1.addChild(icon); sp1.setSize(650, icon.height); return sp1; } and my code scrollview is
//add to the scrollView var scroller:ScrollPane = new ScrollPane(); scroller.width = 650; scroller.height = 505; scroller.y = 0; scroller.addScrollContent(addImage()); addChild(scroller);
Thanks in advance!
Hey shethab,
in order to retrieve the height and width of your image, you must use use the an event listener on your image and check for the Event.COMPLETE event. What is happening because the image you upload is not built, it takes time to load into your application using the setImage() method. and when you check the width height after the setImage method, the image was not loaded and has no height and width to this second. If you use the event listener, you can retrieve the height and width as it was finally loaded.
Try the following code:
import flash.events.Event; //add the image private function addImage():Container { var sp1:Container = new Container(); sp1.sizeUnit = SizeUnit.PIXELS; sp1.debugColor = 0xFFFFFF; sp1.margins = Vector.
([1,0,0,0]); sp1.align =ContainerAlign.NEAR; //sp1.setSize(650, 800); var myPattern:RegExp = / /g; var fileName:String = "./com/swiz/img1.png"; var icon:Image = new Image(); icon.setImage(File.applicationDirectory.resolvePath(fileName).url); icon.addEventListener(Event.COMPLETE, onImageLoaded); //icon.setPosition(0,0); //icon.setSize(320,800); sp1.addChild(icon); sp1.setSize(650, icon.height); return sp1; } private function onImageLoaded(e:Event):void { trace("image height: " + e.target.height + " image width: " + e.target.width); } hope that somethings brightened. Good luck!

Result of the search and common properties
In a logic model I would change the rule of removal for a large number of entities (+ 100)
I did a search in advanced by using a regular expression mode. Seaching for all relationships with the DELETE CASCADE rule.
Using the properties button I can change the rule for all of them, but not a selection of the result of the search.
Is there a way I can select a subset of the search results to edit common properties for?
There is no simple way to improve the filter and filter entities that should not be changed.
It is not a way to select only the relationship sought and then right-click to see a common properties dialog box?
This way I can prevent a lot of repetitive actions...
BTW I don't see not a way to change the parameter 'delete rule' for relationships in the logic model through research - common properties
Hello
I did a search in advanced by using a regular expression mode. Seaching for all relationships with the rule CASCADE.
....
BTW I don't see a way to change the "delete rule' defining relationships I
I also wonder how did you research on 'delete rule' property?
Don't you know that you can combine the search on several properties with AND clause expressions? Then probably you can filter the best what to include in the result.
If not for property 'rule of deletion' appearing in the search, you must edit the file Relations.xml in the directory datamodeler\datamodeler\xmlmetadata of your installation of DM-
You must add the search of the = "true" attribute in the definition of the deleteRule property and restart Data Modeler

Orientation of the Tablet and entirely sensitive Web sites
Hi, I'm trying to get my head around the limitations of adobe muse regarding design entirely reactive sites which, in 2015, should be standard.
first of all, I know that to design 3 different layouts... for desktop PC, 1 tablet 1 and 1 for phone separately, but how adjust you the orientation of the Tablet and phone versions based on the views of landscape and portrait? I don't think it was possible to have 2 different tablets page layouts, 1 for the portrait and 1 for landscape but it seems that this site of the day he succeeded with their version of the Tablet (the phone is identical on both directions)
also, with regard to sites being fully admissible, it is possible to have Office sites shrink and adjust the layout when the browser window is resized on the desktop versions? other sites that are built with things like wordpress etc can do it why not muse?
At this stage, you can use summary, pine and features scrolling browser width.
It's already in our list for further consideration.
Thank you

If you look in the css file over to the figcaption css selector you will see:
figcaption {}
display: block;
text-align: center;
make-weight: bold;
do-size: 14px;
}
As I don't use DW css Panel, I can't tell you how to do that through that, BUT doing it manually just open the file main.css figcaption roller and the type it as shown above.
