• emitting signals with QList as parameter?

  Hey developers

  How can I pass a QList as an argument with a signal? He repeats to me

  "No such signal ConnectionService::downloadCompleted (QList, QString) '.

  I'm emitting the signal with a QList object and a QString. It's my signal

  void downloadCompleted(const QList &connections, const QString &error);
  

  And that's how I connect

  connect(&this->connectionService, SIGNAL(downloadCompleted(QList, QString)), this, SLOT(searchCompleted(QList, QString)));
  

  I have allso tried QList SIGNAL signature. But that no longer works.

  Thanks in advance.

  Spend a full type, i.e.

  Connect (& connectionService, SIGNAL (downloadCompleted (const QList&, const QString &)), this, SLOT (searchCompleted (const QList&, const QString &)));)))

  'const' and '&' can be omitted if it should also work:

  Connect (& connectionService, SIGNAL (downloadCompleted (QList, QString)), this, SLOT (searchCompleted (QList QString,)));

  UPD:

  Try saving the type:

  qRegisterMetaType< QList >("QList");
  

• Notification of instant preview with text entry

  Hey,.

  I wonder if it is possible to add a text entry for quick answers to instant preview, as BBM notifications and Messages. I have not found anything in the API, but it would be really sad if such feature would not be exposed to the public.

  Thank you

  Not now, at least not regular developers.

• Trace the signal with little data

  Hello everyone,

  I have the problem of tracking. I would draw a signal I have greated. I store the profile of signals in a table and this table I want to give with "draw the waveform. The problem now is that my signal may have a minimum of 4 values. The function of "Draw the waveform" plots each position of the table in the graph. With 4 values, the result is a triangle signal but it is false, that the signal should be like a rectangle (signal Wave Drive). There is no action between that. I have the oscilloscope the correct signal with only values in the table.

  In the 1 following you can see the result. The signal has an offset of 5 V, just FYI. The signal should be the signal in the following 2 (orange).

  Hope someone can help me.

  Best regards

  Probably a trace type thin step in PlotWaveform will do what you want.

  You can experiment with styles of different path for example native of race graphs.prj: you can locate with finder example or simply search in the \userint folder.

• market factor two AO signals with a square wave

  Hello

  I use two devices with sending two signals (sine wave) AO out simultaneously in my code. I need to have to cycle my signals. in other words, I want to start or OFF the devices at all times. To do this, I use a generator with duty cycle of 50% square wave. The devices must be running when the square wave has positive values and should be OFF when it is negative.

  The code almost made it, but it doesn't seem to be as fast it's supposed to, based on the frequency of the square wave. I was wondering if someone can help me with this problem. In addition, I'm not sure if this is the best method to do this, please leave me know if there is a better way. I've also attached the VI.

  Thank you

  Pooya

  I thought about it. Instead of the command at the AO signals with square wave and the structure of the case, I just made a square wave from 0 to 1 and multiplied the wave sqaure to the AO (sine wave) signals. In this way, when the amplitude of the square wave is 1, it sends the sine waves and when it is 0 it sends 0.

  Please note that all signals (sine and square) should have the same info of sampling.

• Extrapolation of signal with FFT

  Hello

  I want to extrapolate (generate some outter points a signal given).

  My approach is to use a FFT to acquire the signal spectrum,

  and, to go back to the time domain of the iFFT to generate the new signal.

  But there is no option (iFFT) to specify the size of the generated signal.

  For example, if I have a signal of 1 Hz with Fourier, I must be able to generate a signal with an arbitrary length.

  Is there a function in LV that generate a signal of varying size for each of Fourier Coef gived in entrance (by the FFT)?

  Best regards

• Writing of signals with different sampling to file rate

  Hi all.

  I have a somewhat periodic signal, each cycle having his inerference S.A max, min, mean, RMS ect.

  I like to write * ALL * these data to a single file, with a scale of absolute time, where the cycle data will be stamped with the maximum of the cycle time.

  cycle data columns must be empty at the time as the time of the signal peak value.

  Who's asking 2 questions:

  1. can I build a 'waveform' with a not constant sampling rate where I just stamp each data point arbitrarily? This will help me to get the result I want?

  2. is there a better way to convince labview to write data of the cycle next to the signal, with time stamp correct?

  An example is attached.

  Thanks for the tips...

  10 x Heuter, your example is useful - the problem is resolved.

• Connection of signals (with parameter) in QML.

  Hello

  I want to connect a signal (with parameter) in QML. I have the signal of my PPC and I am able to do that in QML, when I use signals that has no parameters.

  I want to connect to signals which takes the parameter.

  app.mySignal.connect (button.doSomething);

  I do not mySignal() issue, works very well.

  Want to do something like issue mySignal (int) and acess as QML in

  -Thank you

  your signal is:

  mysignal (QString)

  then connect to a function like that (qml)

  myClass.mysignal.connect (onmysignal)

  and:

  function onmysignal (mystring) {}

  Console.log ("my string is:" + mystring)

  }

  If you have several settings, you must be careful with the order and better to use descriptive names, as there is no type in the function definition.

• notification and instant preview

  Hi all

  is there a sampe notice and overide instant preview?

  as to prevent them from be triggered?

  You can of course do it for your own application then I suspect that you ask to substitute other apps as far as I KNOW is not possible.

• High resolution quality of the State of stocks, Adobe and work with the previews?

  I used Sutterstock in the past, but being a CC subscriber, I am seriously investigate Adobe Stock.

  Because you don't actually see the image high resolution up to that after purchasing with Adobe Stock I can't say how easily compare its inventory with Sutterstock.

  I downloaded preview AdobeStock_52339199_WM which was, of course, low resolution and it was much smaller in size (preview 1000 x 662 cases real is 4590 x 3040).  Therefore, I really could not do anything with the preview since it's a "postage stamp" even if Larry White was a video how I was suppose to be able to work with the preview in Photoshop and when done, then buy the license.  And once again, in low resolution, I had know idea, with regard to the quality of the finished product, I'd be buying.

  Any help on these questions would be greatly appreciated.

  Hi Ray,

  I understand your concern. However, from now on, you will only be able to download the image in watermark, which is a version low resolution of the image. If you like, you can buy a version the same high resolution.

  Your comments are appreciated.

• Google instant preview ;(

  Hi all

  Another nail in the coffin?

  http://googlewebmastercentral.blogspot.com/2010/11/instant-previews.html

  They mention the word 'some' videos or Flash content in Previews appear as one piece of the puzzle - not they once more were wrong, based on my research in this, show me all/majority of Flash content is missing previews of form.

  When is Adobe going to this address? First Apple, now google, located next to slam Adobe software. And its US developers/designers who are now paying the cost of this carry on. Now, it will be even harder to push Flash on websites, especially business. It's very disappointing at all, I'm sure.

  What I say when my clients begin to ask me, ' can you fix this?

  Come on boys and girls, is there a solution? Other than to have the sling of Flash in the Pan and just call it a day?

  Next to several jobs now lost, due to the apple/html5 tantram. But it's more serious - and I expect that now that it's about to get worse for all concerned.

  A WTF happening?

  More importantly, someone at - it a solution?

  Boxing boom

  Even if Apple is perceived as a King of usability usability/user, your discoveries on their website are pretty revealing. Besides the site, I would say iTunes is pretty hostile user. Search is terrible!

  Their lack of range of browsers support is symptomatic of a lowering of standards too.

  My point is that, once a company becomes arrogant - this isn't far from be significantly injured.

  Also, I would like to read this:

  http://blogs.Adobe.com/jnack/2010/12/Flash-video-gets-dramatically-more-efficient.html

  Also, don't miss the links to other sites in this post, especially this one:

  http://blogs.Adobe.com/penguinswf/2010/01/solving_different_problems.html

  Although this isn't a new rupture (Adobe talked again made video and native 3D engine during the last MAX), I would like to stress that it seems that Flash is much closer as the most effective way (from the performance point of view) to deliver video, audio and, finally, quickly rendered 3D. Search in the posts that I mentioned above, HTML5, or any other technology is considering even multimedia application performance improvements.

• Not able to scan with the preview after upgrade from Mac OS Sierra...

  After upgrading to Mac OS Sierra. I'm unable to use the preview to scan.  Before this upgrade, it worked fine.  The HP scanner software does NOT work something like OS 10.8 or 10.9.  Preview worked perfectly so far.  If anyone knows how to solve this problem, your contribution will be greatly appreciated.  Thanks in advance.

  Have you tried scanning with Capture of Image instead? It worked for me.

• Weak signal with airport Extreme

  Hello, we have an Airport Extreme tour in our condo. The signal is that two of our rooms is low. Is there a way to increase the signal? Not Apple or any other extenders of sale of business or boosters?

  Thank you

  Another extreme airport would be the perfect match to extend the signal of your "main" AirPort Extreme, but an AirPort Express pourrait point be good enough for your application, if the budget is limited.

  Ideally, the second airport would be located in the middle of the area where you need more wireless signal strength and then connect to the 'main' airport using wired Ethernet wired, permanent.

  It is possible to have the second airport to extend the first using a Wi - Fi connection... IF... the second airport is where he can receive a strong signal from the first airport.  A good location is at halfway between 'primary' airport and the area that needs more wireless coverage.

  Remember that when you extend wireless like this, there is always a loss of about half of the potential wireless speed on the network, then the result will be a network with the best range, but reduces the maximum speeds.

  The more you have line of sight between the airports, the network will be operated. Or, another way of saying the same thing, is the 'extension' airport to expand the speed of the signal it receives. It can make the stronger... wireless signal but can't go faster.
