What is the best way to refresh one when its interface elements user is updated?

I have a Page in a NavigationPane. I click on a button that is immediately disabled while I perform some behind the logic of 'scenes' (a little humor BB). After that I'm done, I would like to re - activate the button.  I found how I can modify the attributes in the code, but the screen remains the same.

Basically, I have the same problem as this guy:

http://StackOverflow.com/questions/12482464/cannot-access-QML-object-in-c-code

I need to store a pointer to the application object, and continually call setScene? Do I always have to set the scene for the Navigation pane, since that's what I'm pushing my pages on?

Is there a cleaner way to do this?

Thanks again, guys.

Well, that looks more like the real solution. How I would emit as a signal?

I am a native Android and it is usually automatic. Could you show me a code snippet?

Here are some of the code I use:

Getting button:

signInButton = getOwnedPage()-> findChild (SIGN_IN_BUTTON_OBJECT_NAME);

Later...

signInButton-> setEnabled (true);

signInButton-> setProperty ("text", "wutwut");

qDebug() < signinbutton-=""> text();

signInButton-> setText ("hey now");

qDebug() < signinbutton-=""> text();

I have the debugs to prove that I'm actually changing the properties of this object, but it is not yet reflected on the screen.

    What is the best way to refresh the table after autosubmit?

    I have a page that contains a table where if one of the fields is changed it autosubmitted where the view object changes some attributes, based on the field having been changed. I need these modified attributes that appear in the table. But without doing anything, the only way to see these values is to cause the iterator updated table.

    I've been refreshing the table is having a method in a grain of beacking called "getSystemSettingIter.getCurrentRow ();". This seems to be a bit of a hack for me and I was wondering if there is a better way to get the table to update.

    Thanks in advance!

  • Forcing a file DOWNLOAD vs open a file when you click on a link... What is the best way to do it?

    Hi all

    What is the best way to ensure that when a user clicks a download link on a web page that the file is actually downloaded rather than the file open in any program can read? For my case, this includes two types of files, video files (.wmv, mainly) and .pdf files. I want my users to browse I provide for them, then they choose a link, click and the file downloads, NOT to have them play/open.

    I started researching on this last night, and the best I could come up with was the suggestion to add "& action = 3Dsave" file as a query string name. So, me being curious, I tried without success to find out whether A) the right way to do it or B) If this query string is the code appropriate to today's standards.

    I looked on the Web site of w3c.org not knowing if it was something that was of their Kingdom, but their website has been revamped and is now so cinfusing to navigate that one must become a software engineer to understand.

    Any help on this would be most appreciated. Thank you!

    Sincerely,

    wordman

    Create a file with the same name as the video/pdf file but with the extension .php. Insert the following code at the beginning (NO space before that in the file):

    <>

    Header ('Content-disposition: attachment; filename = yourfilename.xyz');

    Header ('Content-type: abc');

    ReadFile ('sourcefilename.xyz');

    ?>

    Replace with the file name to "yourfilename" above. sourceFileName may be the same. This gives you just the ability to change names.

    You can find a list of the types mime here: http://en.wikipedia.org/wiki/Mime_type

    If you know php, you have a lot of files, it would probably be easier to have all the links go on one page with the filename and mime type as parameters. You would then use the simple substitution to do the rest.

  • Apple Extreme, Time Capsule and Express on the same system, what is the best way to set it up so that all devices smoothly from one end of the House to another?

    Apple Extreme, Time Capsule and Express on the same system, what is the best way to set it up so that all devices smoothly from one end of the House to another?

    I'm going to assume that you plan to have wireless devices.

    Let's say that the Capsule is your "main" router  If this is the case, then it must be located in the House, so that the distance between the time Capsule is the same for the outside walls of the House.

    Then, on the 'left' side of the House, looking for an airport to midway between the Capsule and time of the outer wall of the House. Do the same thing the 'right' side of the House.

    In other words, each of the two airports that "extend" the wireless signal are located at equal distance from the Capsule of time... but they are in opposite ends of the House.

    If you intend to interconnect all the airports and Time Capsule using a permanent, Ethernet wired... which by far is the 'best' way to put in place a network in terms of performance and reliability... then you can locate one of the devices anywhere you want.

Should I get the T-Mobile one full fare? I know that he will be released version but it will come with a T-Mobile sim so what will do with the sim card? Put it away or give it to T-Mobile?

    I have a song that is most often improvised, I was told that his cool, however, re-registration is not possible.

    After reading a lot on the mixture, I now hear where the uneducated choice and errors that I made which explains the sound "not as good" that the song is.

    Before I just jump in and try to undo the settings on the tracks (one is DRUMMER) to return to the raw track before effects/eq/compression ect. is is possible to do?  Opens the unfavorable mix, rename it, save it and just go to work and cancel or disable 'things '.

    The basis of the lean mixture comes even to the root where I 'hot' securities, (orange and red)

  • What is the best way to move and organize records

    I recently bought a Mac Pro and have bought files across the FRO my windows laptop but what is the best way to organize the files iCloud or local drive and how do I move files in my list of "all files" in individual cases.

    In case you are not aware, all the files that you put in iCloud drive are on your disk local and iCloud.

    You can go to preferences in the Finder menu and specify whether you want iCloud drive to display in the sidebar of the Finder. I find that having it in the sidebar makes it easy to use. I also have other folders I used frequently in the sidebar; You can add the system ones (Documents, downloads, etc.) using this same preferences window. You can add folders that you created them by dragging to the sidebar of a Finder window.

    A way to move files into folders that you created is to open 2 windows in the Finder and drag it from one window to the other. Another option, if you move a file in one of the folders that is displayed in the sidebar is just do it from its current location in the main area of the Finder to the folder window in the sidebar in this same window of Finder.

  • INTERFACE design - what is the best way to allow the user to define a kind of infusion at various times (non-periodic)?

    I want to allow the user to specify a curve like this:

    Such as some under - VI shows the A2 value when a variable of time is between R1, A1 when the time variable is between A2 and A3 when time is in the range A3.

    My design looks like this:

    With the error checking that looks like this:

    My question is, is the approach of the table according to optimal? Otherwise, how could combat this?

    I think I can summarize the conversation on this point as a response to the original question (what is the best way...) -to start writing code, to think about what you want to accomplish and write it down (otherwise known as 'Write the first Documentation').  One of the points of a good User Interface is that it is not allow users to "stupid mistakes" - it leads the user "by hand", limiting the entries to the "legal values" and demanding that the entries be made logically.

    If you were going to have a list of Infusions to enter, it is therefore logical to decide or not to enter into time intervals (which are always > 0) or order the times (which, logically) are still growing.  You can (and should) decide that you (or you may have a control that allows the user decide, but maybe it's too flexible) and then apply your "rules".

    Let's say you've decided on "Intervals" (which seems to me to be more User Friendly).  After the user has entered the intervals (and you've provided a nice plot of perfusion vs. time), pouvez allow you the user to an interval of 'split', 'Delete' an interval, or "Edit the Infusion" interval, or you can decide to have a choice more simple "accept or start again" - If you have only a few intervals, the last would be the simplest (and therefore best) design choice.

    Spend more time thinking before coding usually pays Big dividends!

  • Any transfer on a drive hard new - what is the best way?

    Here's a question simple and straightforward, I hope. I currently have two internal hard drives:

    • C (IDE): OS (Win7), programs
    • F (about three times larger than C, faster, SATA): for most of the multimedia stuff

    (And some external and a dvd burner, which should not be relevant to this question.)

    I ordered a new hard drive, which will take over old job of the F drive. Once I have install and F empty on it, I want to move everything that is currently on C for which is now F and the new C drive I start and run Windows from. (C would also get a new drive letter and would only be used for backup purposes).

    I much prefer this without having to reinstall Windows and all my other programs, and without investing in expensive software of type Ghost I would probably use only once every two years or more. I also prefer not to have to partition F, although I'll do it if necessary.

    What is the best way to do it?

    Windows 7 image and move it to the new hard drive

    The only way to avoid reinstalling programs is in the image of the player. Connect the new drive as a slave (if IDE), then partition the new drive, so it has two partitions (or more if you want) - the last partition being slightly larger, then the amount of data on your current hard drive. Also, make sure that the partition you are moving that Windows 7 is greater, then the current partition is.

    Make now a picture of your current hard drive with either programs below and save it to the last partition on your new drive. If you have the recovery of 100MB partition do not forget to include that. Then restore the image of the partition that you want Windows 7 installed-you put in place the same as long as your current drive, and you may need to remove/change the partitions that you have done.
