adjust the height of the custom via AS3 component

The lower class is used as a custom itemRenderer and I want to adjust the height of the VBox to its contents (child), or perhaps the easy way would be just set it to 90%. But it needs to be reset every tempsThe dataProvider is passed.

SerializableAttribute public class TextDynamicLayout extends VBox
{
// .. code removed for brevity

override protected function measure (): void
{
Super.Measure ();
percentHeight = 90; This does not work as expected
measuredHeight is MaxHeight = 50;.
}
}

As you name the class TextDynamicLayout, it means you are trying to manage the text back.  It requires transmission explicitWidth the VBox for controls of text before they get measured.  Return text can be any size, so it must have fixed width to determine its height.

The list classes do not support percentages on rendering engines.  All converters are actually given a size according to the size of the list (or the size of column DG).  You can see how explicitWidth is handled in the default rendering engine by looking at the source for ListItemRenderer.as.

Note that VBox or any container is made for a cumbersome and slow.  That is why the Flex UIComponent to extend default rendering engines and have custom Measure [] and updateDisplayList() methods.

  • Access to the customer via VNC in VMWare Server 2 (has that changed?)

    In earlier versions of VMWare server, it was possible to connect to a virtual computer remotely via a VNC client (or customer using this Protocol). Test with VMWare Server 2 that doesn't seem to work. I know that via the Web Interface, they start their own remote console player. Does anyone know if it uses another protocol of VNC (RFB) such as used previously? Actually now is no longer an open soluton?

    I think you should also add the RemoteDisplay.port = "5900" (or whatever port you want) as well.

  • create the custom in JavaFX component

    Hello!

    I am new to JavaFX, I'm just starting to learn, and I managed a problem.
    I need to create a custom in JavaFX (using fxml) component.
    Long story short: I have a request for the witch, I'll have a 'Party' which will be common for most of the 'scenes' ("pages"). This part must contain a menu, a logo, labels, 2-3 buttons, etc, and I should be able to fill in some of the labels based on data. That's why I thought I got better create a custom component and use it on all my pages (scenes). The problem is that I not found information on creating custom components (I have... a custom control, a button, label, or something like that, I need a custom component) on the internet.
    Could you please tell me if this is possible? I mean is it a way to create custom using JavaFX components?
    This component can act as a controller (define the properties, values get...)?
    Can you help me with documentation?

    Thanks in advance!

    HI - you're looking at him the wrong way. What you need in terms of FX2 is a group that is a collection of standard items.

    Define a class that extends the group.

    Put all the items you need in the definition, then finish with

    getChildren.addAll (your items);

    It is then your custom control.

  • The height of the custom selector.

    Hi all

    I wanted my fall down to have multiple lines in a single option.

    But this is not possible, so I implemented the custom selector and put 2 in the same tag,.

  • How to adjust the height of a separator?

    2 Add listeners to tune-up for the tabs horizontally.

    3. to select a tab on the selection by changing the background color.

    4. setting the focus to a text field, say search after selecting a tab.

    Thanks in advance.

    OK, I understand, but I suggest if you are totally new, you learn what you both and your knowledge.  You also start slowly.  So for this thread, let's focus on the variable height SeparatorField.

    Start another Thread for each individual question, ensuring that you explain in detail what you are were trying to do and what is happening.  If you say something like "when I change the update of a text field its new adding another set of fields' this is clearly a bug in your code because standard code doesn't do this, then we will need to see your code.  But do give us all your code.  Try to reproduce the problem with a very small piece of code (10 or 20 lines maximum).  You will often find that when you start from scratch, try to re-create the problem, you find your bug.

    But in this Thread.  Since a variable height that separatorfieldof does not exist in the API, you must do it yourself.

    Here is a post that I think will provide you with the details you need for this:

  • Monitor the U2311H - how to adjust the height?

    Hello

    I would like to adjust the height of the screen but can't see how to do it.  It is apparently a rack mechanism that allows the monitor to slide.  Mine is very steep or locked.  It cannot be moved by hand.  Does anyone know how to fix?  The installation sheet and the manual did not help.

    Thank you

    WMcGinty,

    Looks like it's stuck. Turn the monitor off. Put a towel on the desktop. Put the side display monitor down on the towel. Remove the media from the screen. Set the booth on the desk and try to move it downwards and upwards.

  • problem of adjustment of height of the rows in the tables in CS6

    I read all the debates devoted to setting the height of the rows in the tables and I can't find the answer to my problem.

    I placed a table that was created in Word.  I've done several times, but now I can not adjust the heights of less than 5mm line without losing the text in the line.  I went up to line on "exactly".  As soon as I try to reduce the height of the text disappears, but there is plenty of space above and below the text.   Hoping someone can help.
