How to identify the origin of a signal

Hello

Suppose I have created multiple TextField objects and add them to a container.

for (int i = 0; i)< options.count()="" ;="">

{

TextField * textField = TextField:: create()

.objectName ("textField" + i)

.hintText ("your text here...");

bool res = QObject::connect (textField, SIGNAL (textChanged (QString)), this, SLOT (myTextChanged (QString)));

someContainer-> add (textField);

}

Further, I connect each object for the same housing: myTextChanged

void App::myTextChanged(QString NewText)

{

qDebug() < "newtext:=""><"><>< "="">";

}

It works very well and I am getting the contend of textfield in NewText.

I need to validate the text and colorize the associated TextField accordingly.

But I don't see any possibility of easy to identify which of the many cases of TextFields sent the signal.

A possibility would be to itterate through all the TextFields in the container and get their text against NewText.

What are the possibilities (and better) I have?

Thank you very much

Thorsten

In your home, you can call the sender() function:

void App::myTextChanged(QString NewText)
{
   TextField *textField = qobject_cast(sender());
}

  • Library ITunes-how to identify the original track

    I've searched the forums looking for an answer to this and it seems to be the same issue that dates back to 2007, so I guess the first question would be why Apple has not done something, rather than causing me problems whenever they release an update iOS

    OK - rant over! Now, I know there's the possibility of using the "remove duplicates" in the menu, but I had this problem for a while, and when I tried to remove the titles before, I got a warning message telling me that I was going to delete the original - so, how do I find which of the indicated path is the original?

    Now, I have six or seven copies of each track and suspect that this happened since a previous update changed my settings and deleted something that stopped the tracks are copied back to the devices in iTunes.

    Has anyone found a way to identify the original track so that I can remove all duplicates?

    Thank you very much.

  • How to identify the virtual copies (in my records) that have already been deleted a collection

    Hello!

    I keep looking for an answer to this anywhere on the web and 3 books, but can't find the answer...

    How to identify the virtual copies (in my records) that have already been deleted a collection?

    Here's the workflow, and where I'm stuck.

    1. I chose a picture and put it in a collection.

    2. I did a whole bunch of virtual photos in the collection copies that I tried different modifications.

    3. after and during a lot of changes, I have a lot of virtual copies removed from my collection because I decided against the changes after doing some comparisons.

    4. when I went the folders to select my next picture to work away and so to add to the collection, I discovered that each of my virtual copies was in the original folder, even if I had deleted from my collection.

    5. I really don't want these virtual copies deleted to be in my home folder.  They were virtual copies of trial and error and I wanted them to really just be thrown out.

    6. how to identify these virtual copies removed-from-the-collection in my folder?  File names all look the same, and besides, I want to be absolutely certain that I have selected the right ones.  Some of the changes were very minor and would be difficult to see without laboriously go through them one by one.

    Thank you very much!!

    Anne

    No easy answer on fixing the mess other than an individual inspection of the virtual copy can't watching the Images/Edit history to determine which ones that you no longer need.

    But to help prevent the problem in the future: when you are working from a collection, you must use ALT + return back to remove a copy of Photo or virtual catalog. With just the key DELETE or BACKSPACE only deletes the photo from the collection.

  • How to store the original and to remove some duplicate songs in iTunes on a PC Win7, which took place after iTunes to scan for music during a re - install?

    How to store the original and to remove some duplicate songs in iTunes on a PC Win7, which took place after iTunes to scan for music during a re - install?

    I recently had to format my hard drive and reinstall iTunes 12.3.2.35 on my Win7 PC. As part of the re - install iTunes, I clicked on the button scan for music.  This has created duplicates several of my songs.  I deleted then the duplicate songs from iTunes, but when I went to play a few songs a pop-up said "the song would not be because the original could not be found.  You want to locate? "When I tried to locate the song it is not found, but when I pulled the songs out of the trash they could be found.

    How can I keep the original and remove any duplicate songs in iTunes on PC Win7 which took place after iTunes to scan for music during a re - install?

    iTunes can create duplicates if the same content is added several times from outside the media folder when it is about to make copies of everything that is added to the library, or is added from an external drive that hosts the press kit that was disconnected during the launch of iTunes.

    Official notice of Apple on the duplicates is here: find and remove duplicates in your iTunes library. This is a manual process and article fails to explain some of the potential pitfalls such as the lost coast and membership of playlist, or sometimes the same file can be represented by multiple entries in the library as well as a removal and recycling the file will break all the others.

    Use MAJ > display > show items to reproduce exactly to display the duplicates because it is normally a selection more useful. You must manually select all but one of each group to remove. Sort the list by Date added can make easier select appropriate tracks, but it works better when executed immediately after the dupes were created.  If you have several entries in iTunes connected to a same file on the disk hard then don't not send to trash.

    Use my DeDuper script (Windows only) If you are not sure, do not want to do it by hand, or want to maintain ratings, play counts and playlist membership. See this background thread , this post for detailed instructions and Please take note of the warning to back up your library before deduping.

    (If you don't see the menu bar press ALT to temporarily view or CTRL + B to keep displayed.)

    The latest version of the script can put away the dead links as long as there is at least a double live to merge his stats and membership of the playlist and must deal wisely when the same file has been added through multiple paths.

    If you want to load screens on selcting a menuitem from the GUI go to create menuItem.

    In the case depends on certain conditions of your application then just use

    try
      {
           UiApplication.getUiApplication().pushScreen(TestScreen);
      }
    
    catch(Exception e)
    {
    // PUSH screen fails because the screen was already pushed.
    // remove the screens from top of the required screen.
    while(UiApplication.getUiApplication().getActiveScreen() != TestScreen)
    
      {

  • Restoration of openers program: how to restore the original program of opening such as internet explore and itunes instead of notepad ++

    on my computer, I have somehow changed the settings for applications on windows 7 open with notepad ++ how to restore the original program of opening such as internet explore and itunes instead of notepad ++

    I've seen this happen when opening a program via a shortcut (for example. LNK file), you are asked what type of program to open it with. After selection of Notepad ++ (or another program) via the Select a program from a list of installed programsand checking the always use the selected program to open this type of file, document or program referenced by the shortcut of origin opens in Notepad ++ as it should.

    The problem is that now all shortcuts (for example. LNK files) on the desktop or in the browser will want to open Notepad ++ and use the icon of Notepad ++ to display the shortcut no matter what shortcut was originally intentioned to open. This is known as a file association and the default icon.

    The good news is that a small free utility was written to cancel the. LNK file association was created. There is also a registry hack to achieve, but I recommend the utility unASSOC for its ease of use.

    A utility to Unassociate Types of files in Windows 7 and Vista

    Just download and then use the utility to unassociate the. LNK files. Manual is available on the web page above (the same place to get the utility). Quite simply, you run the program and wait for the list of the types of files to complete. Select. LNK in the list and then click delete the file type.

    Stop disconnect the external drive before you delete the catalog releases and select Remove from the disk.

    Otherwise, you will need to manually, delete them externally or reimport then them select all, make sure previous import is selected, Photos and then delete and remove disk.

  • How to identify the Protocol of network storage using PowerCli

    Hi all

    Does anyone know how to identify the network storage protocol using Powercli? If you do could you please point me in the right direction and appropriate controls to be used.

    Thank you.

    See you soon

    With the Get-EsxCli cmdlet, you get to many of the features esxcli.

    Something like that

    $esxcli = Get-EsxCli -VMHost MyEsx$esxcli.storage.core.path.list()
    

    You can use Select-Object to choose the specific properties of the returned objects.

  • How to identify the primary Parent of a shared node?

    We have a property that is set to Local defined, inherit,

    Suppose the 'Color' property and currently is the behavior in DRM

    Parent A - blue

    Child 1 - blue (inherited from Parent)

    Child 2 - color blue (inherited from Parent)

    Child 3-color blue (inherited from Parent)

    Parent B - Red

    Child 3 ~ part 1 - red color (inherited from Parent B)

    Child 4-color red (inherited from Parent B)

    Children 5 - red color (inherited from Parent B)

    The customer has improved the requirement so that in the case of shared members 'color' is inherited from the primary parent like the example below.

    Parent B - Red

    Child 3 ~ action1 - blue (inherited from "Primary" Parent A)

    Child 4-color red (inherited from Parent B)

    Children 5 - red color (inherited from Parent B)

    I guess I'm going to need a new property like 'Primary colors' and I need to write a formula to calculate the color of base on the primary parent.  However, I do not know how to identify the "main Parent" a shared node we use version 11.1.1.2 N-Tier

    I'm looking for suggestions on how to calculate the value of the property you want.

    Any help will be greatly appreciated.

    Hello

    You can create a new property derived like u said and use instead of the property defined in your exports or anywhere where you have to refer to the color. The property set can be used just to take the user input.

    The new derived property should be a logic like that-

    If (PropValue (Core.SharedFlag_MDM),

    NodePropValue (PropValue (Core.PrimaryName_MDM), Custom.Colour)

    PropValue (Custom.Colour))

    Now, 11.1.1.2 I lost the memory of how the properties are referred to as - if they are just used with their names or namespaces is mentioned (Core. , custom.). You can change the formula accordingly to view properties

    Thus, if SharedFlag_MDM is True, then it will take the value of the property to its primary node, which is inherited from the primary parent and if the shared flag is False then it is just a varValeurProp on the node itself.

    I hope that answers you.

    Thank you
