determine the size of the components after change

Hello

I have a little problem. I have Hbox component label inside. When I change the text of the label, hbox size is automatically changed after the code is executed. But how to know size Hbox, or size label (for example width) once after you change the text property of the label... For example...

var myHbox:HBox = new HBox();
var myLabel:Label = new Sun;

now the Hbox and lablel the width and the height is zero. It is clear.

Now I change:

MyLabel.set_Text = "Some Long Text.
myHbox.addChildren (myLabel)

But now if I want to determine the actual size of the size of label or hbox, it is always zero.

How can I determine the size at the same time, when I change the text of the label.

Thanks in advance

Once you have made the changes to the child components, the Flex framework through an iteration to measure children and setting the new size of the HBox.

You have a few choices. First of all, once you set the size of the label you can do: myHbox.validateNow () and then myHbox.getExplicitOrMeasuredWidth () (there is a version of height, too) to get the new size of the HBox. This does not allow the natural process of the Flex framework to sink, but it should do the trick.

You can also try to add an event listener for the resize on the HBox event. If changes to the child cause the HBox to have its size changed, it must trigger a resize event.

I recommend doing this first.

  • HP 200 MFP M276nw not seen in the network after changing router

    Printer: LaserJet Pro 200 color MFP M276nw

    LAN: both PC (Windows 7) and the printer connected to the router.  Other devices connect wirelessly.  Internet service is cable.

    I installed this printer when a router Linksys E2500 was in use.  The configuration of the network after the installation of the printer:

    IPv4 address: 192.168.1.120

    Subnet mask: 255.255.255.0

    Default gateway: 192.168.1.1

    Configured by IP: DHCP

    I replaced the router Linksys with a Netgear WNDR4500 router (N900) a month ago.  Everything worked fine for about two weeks.  All of a sudden, jobs sent to the printer began to take a long time to start to print until they stopped printing altogether.  The printer does not appear as a device plugged (cable) in the interface of the router on the Web.  Not even the HP Print or HP Print software and the Scan doctor could find a printer is connected.

    I have unisntalled and reinstall the printer, but did not succeed until I changed the Ethernet cable connecting the printer to the router.  The difference is that the old cable Cat5e and replacement a Cat6?  It's printing and scanning now but the printer is still absent as a wired device, and I fear that it will stop working once more.

    I noticed that the network configuration of the printer after reinstalling is:

    IPv4 address: 169.254.230.140

    Subnet mask: 255.255.0.0

    Default gateway: 169.254.230.140

    Configured by IP: AUTOIP

    Research on the Web, I found an article saying that AUTOIP could be a sign of problems of router or a cable.  My suspicion is that the IP address of the printer is constantly changing and this is the reason for the delay of printing.

    My questions to the experts are: I could assign an IP address to the printer manually so I can add it in the router - it provides to this effect- and how this is done?   In the Toolbox of device HP under the IPv4 Configuration, there is a dropdown menu with different options - DHCP, BOOTP, AUTOIP, and manual, but I don't know if the changes are made here or if it's a more complex undertaking.

    Thank you very much.

    Kind regards

    I solved the problem, the same day I posted the request for help.

    I've closed everything down - including the cable modem and router - but left the printer.  Go to the printer control panel and changed is manual configuration IPv4 of AutoIP toe.  I had already selected an IP starting with 192, since I read that starting with 169 IP addresses are associated parameters AutoIP.  From there on, the printer has presented a valid subnet mask addresses, I took one, and a default gateway address.  Then I stopped the printer.

    I turned on the modem, router, pc and printer.  The router then showed the printer as a device connected with his newly assigned IP address.

    I figured that the cable was not a problem here, so I put the Ethernet Cat5e cable.  What baffles me, is why the printer changed to AutoIP because it was not made by any user.  Check the reports printed during the first installation of the printer, I see that the method of IP in DHCP address.  After putting in the new router, changes were to name SSID and password in wireless devices and found the firmware of the router.

    It was learning by trial as I'm not a computer expert, but so far, we print and scan documents.

    Thanks to all who took the time to read the post and offered help.

  • Cannot recreate the listener after changing the ip address and the name of the server

    Hoping someone can give me some ideas - I do not know what else to try.

    I run a 11.2.0.4 database on windows 2012.  I just got back my database to a new server and am trying to rename the server and assinging the new ip address.

    I stopped all the oracle services and change my servers ip address and name.

    Then, I dropped the listener who has been spending more time than it should have, but when I checked that the service has been removed.

    When I try adding the listener it hangs right on "would you like to configure another auditor?

    Then, I realize very quickly that I forgot to change the environment vairable HOSTNAME and the TNSNAMES file.  I cancelled the wizard still Net and

  • inspect element - how to save the report after change

    Hello

    When I create an interactive report and apply "leap control" option it interrupts the report according to the requirements of the standard with a button (+/-sign) on top for show/hide selection... I need to show the report with "Control Break", but don't want to show (option button at the top + /)

    When I inspected the element (using internet explorer) and deleted the text and gif file... the report displayed exactly how I wanted it...

    My question is how to save this report after making the changes in HTML format (with the help of inspect option element)... I did tried to register under default report, but the report got refreshed and +/-sign came back...

    Please advice

    Hello

    When you look at the page source and modify it, it only affects your active HTML document.
    You cannot save those changes to Apex.

    You must use JavaScript and example dynamic action to change HTML each time when the report is rendered or refreshed.

  • Problem with the drivers after changing Vista-> WinXP on R61i

    At first I want to mention that I am new to this forum and my native language is not English (sorry for the mistakes of language).

    Computing: Lenovo R61i 8943 g

    Foreplay:

    In the new computer Windows Vista has been installed, but I decided to switch to a Windows XP Professional.There had a few issues with the SATA controller (computer has no floppy drive). After all, I managed to install a new system.

    Description of the problem:

    I can't install the drivers to the computer (internet does not - same wired: ethernet, there is no sound, etc.) In Control Panel-> system-> device-> devices Manager there are yellow questions marks (with small exclamation points) around: network controller, PCI Device, unknown device (what is?), video controller, and video controller (VGA compatible).

    There is no CD that came with this computer, so I tried to find the necessary drivers on the internet.

    On the page

    Lenovo, drivers and downloads support

    I chose [network] to refine the results (first I want to activate ethernet Internet connections) and clicked on

    Broadcom NetLink Gigabit Ethernet software for Windows XP - ThinkPad R500, R61, R61e, R61i

    There is a file 7yra02ww.exe. At the last moment of the installation, the following window appears:

    Broadcom NetLink Gigabit Ethernet Software for Windows has encountered a problem and needs to close. We are sorry for the inconvenience.

    I don't know if I tried to install the appropriate driver. After I tried to install Access Connections (think Vantage Technologies) of

    ThinkVantage Access Connections for Windows XP, 2000-computers portable, but it also fails.

    Could someone help me what to do (what drivers to install and how)? Thank you in advance. Matthew.

    Thank you, Tim_Lenovo. My second post was about a possibility of making the easy instalation, but no one answered. Thanks - next time I'll use the system update

    I don't know what you got almost everything square away exactly means (I'm not so good in English), but I think it speaks of my redundant work.

    And the solution of my problem is very easy! I installed what it takes and just use the control panel-> power-> advanced options. (I think that my mind needs a rest!). In device manager there is a yellow question mark on unknown device (without power management there are two unknown devices without driver), so I thought that I need an additional driver. That's why I was always looking for appropriate software. A solution was so close to me

    I hope that the system update helps a lack of driver for a device unknown (I wonder what it is).

  • Could not launch the game after changing settings

    Hi what happened was that I was in my call of duty black ops computer game 2 when I changed a setting for graphics in this game when I hit apply the settings he began the program and now it won't let me back in the game to reset the settings. What can I do? Help, please

    Hi Dennis,

    1. you remember what is the change you have made?

    2. what happens when you try to run the game?

    3. do you receive any error messages?

    Looks like you might have changed the resolution of the game. I suggest you to check if there is no specific file to change the resolution or the graphics settings. You can open the game folder and check.

    If the problem persists, perform the restore of the system to an earlier point when the game worked.

    System Restore can return your files system to a point in time before you noticed a problem, without affecting documents, photos, or other personal files. If the system restore does not resolve the problem, you can undo the restore operation and choose a different restore point.

  • How to refresh the table after changing model

    12.1.3 JDEV

    My Table of the ADF is limited to a list of dataRows in my SampleDataModel class.

    My button is limited to a method of createDataRow of SampleDataModel class.

    Then click the button, a new item is added to the list of dataRows.

    There is a partial trigger button on the table.

    I expect after the button clicked, the table is updated with the newly added row.

    But what I see is: new dataRow is added to the list of dataRows and the flashes of the table, but it does not show the line.

    Anything I missed? Thank you.
