• Replacement of the controls from a custom palette gives poor control

  I customized my palette of control system style with a few additional system style controls (tables, clusters, channels DAQmx etc.). Everything works fine when I place a new control on a vi FP, but when I try to replace an existing one I control sometimes get control, depending on whether the scheduled replacement comes after my additions in the file of the custom palette.

  The following sequence of images shows the bug.

  

  Speculate, I would say that looks like replacement who fell is the control that occupies the site because the desired control was in the original palette file (i.e. LabVIEW seems to be getting control of the writing, but then he indexation of pallet uncustomised file.)

  Are workarounds - learn the mapping between the selected replacements and unmovable and not to customize the palette file. None are particularly desirable.

  Hello

  I've found a workaround. After inserting my custom control, got a palette edit discovers that looked like this:

  

  Then I rearranged it and remove empty lines/locations:

  

  And it works normally. Please could you try yourself?

  I hope this helps!

• How to call javascript in an another QML

  Hello

  I have 2 file QML file qml 1A listview with ArrayDataModel as the source of data, when the user clicks on a line, it nav push another QML to change/remove, the arrayDataModel consist of a given amount of time, which 1 contains a qml file label to display the subtotal of all time values in the data model. I also have a javascript that will do a loop through the ArrayDataModel to update the label of the total time that I call the file onCreationCompleted 1 qml, all works well.

  However, when deleted, the listview will automatically update, now the problem is how can I trigger a refresh on qml file 1 in order to update this label.

• Can I call a custom outdoor function?

  Can I call a custom outdoor function?

  For example

  //______________________

  var myComp = app.project.activeItem;

  createComps();

  createSolids();

  RenderItems();

  //______________________________

  but these functions are written separately in the current directory .jsx format?

  As a library?

  #include <>?

  You gave the answer to your question: you can use #include 'path/to/file/to/include.jsx '.

  And the path can be absolute or relative to the current folder.

  See the JavaScript ToolGuide for this (it does not appear in the AE script guide since it is common to all applications).

  You can also use $.evalFile (pathToFile), which has more or less the same effect I think.

• Customize the form to call anothet custom form

  Hello
  
  In the form (APXINWKB) of the Bill, when I select the corresponding method in the order form and click on the game, it opens the corresponding (APXPMTCH) form and enter the purchase order number and click search, it should open the custom form. I have adapted the form APXPMTCH. Can I call the custom using customization form. Can someone give me the steps to do this.
  
  Thank you
  HC

  You can personalization by the user to call another form. However, this approach is to use the Tools menu.

  It seems that you want to change the form that opens when you try to match.

  In this case, try the following.

  Go to the screen to FORM in the responsibility of the application developer and create a new record for the new shape that you have developed.
  And then go to the screen and FUNCTION to change the form that is attached to the function 'AP_APXPMTCH '.

  In this way, when the workbench to invoice calls order form corresponding to the form, it should open your custom form.

  It might be useful as you watch the Oracle applications developer's guide. http://download.Oracle.com/docs/CD/A91568_01/Acrobat/115devg.PDF

• Custom QML control... If I can have a property?

  Hello

  I created a simple custom control, but I want to be able to adjust the height of it when I create.

  Now I can put the preferredHeight of each child control of the custom control, but it seems wrong.

  According to me, I have to set a property on the control, then all my child controls use this to set their height.

  But I can't find examples like this one or a reference to a custom; property can I create my own property to store in qml, then child controls (buttons, images) use this property to set their height?

  Thanks in advance

  You can do this kind of things. Sorry I don't have a reference of the GLib documentation:

  import bb.cascades 1.0
  
  Container {
      id: root
      property real height: Infinity
  
      Label {
          text: "My Label"
          preferredHeight: root.height
      }
  
      Container {
          background: Color.Red
          preferredHeight: root.height
      }
  }
  

  It is obviously an artificial example, but it should help you get started.

• The class call Java Custom WCC?

  How to call a Java class customized WCC when a certain field of metadata is set on "On" and at the time of check-in?

  Thank you

  Randy,

  You would control this logic within your code for FilterImplementor.

  Retrieve you the values of metadata fields and if they meet the criteria, continue with your custom logic. If not, go back and do nothing.

• Is it possible to call a custom method in the App Module to a backing bean?

  I would like to know if a custom in the App Module method can be called from inside of a pod of support.
  I don't know if it is logically just call, to a backing bean, a custom in the App Module method. But I would like to know if this is necessary or if it is possible.

  Hello..
  Yes it is possible. You must add this interface method customer of AppModule.Now you can see this method in data Controls(Refresh the data control). To call this method using bean, should be added as an action method links (click on links > + > methodAction > and create the binding of the action).
  Now, you can call this method in the bean class.

• Called Labview VI cannot find its controls or subvi

  My application consists of:

  A standalone .exe that calls graphic VI containing generic and VI controls.

  My app works very well in the development environment, but when I deploy the secondary can't find it's the generic controls or vi (he uses the paths of the vi of the development environment).

  I have included these files in the .exe in the expectation that the sub called vi would know where to find them.

  Alas, this isn't the case.

  These controls and vi are used in the usual way, and not by "reference open vi" both trace band style operations are not an option.

  --

  A simple solution is to insert multiple copies of them in the library of each auxiliary Panel under vi .llb

  These files are generic and used in multiple under vi, in the spirit of reuse and management of the code, this method is a bad habit.

  A single vi is a global variable functional, shared between both the appellant and vi.  Who will no doubt shock the code by the performer in 2 separate cases.

  ----

  Is there a way for the secondary sub VI to find it's generic controls and VI by calling .exe?

  ---

  A solution to this problem would be highly appreciated.

  Tim L.

  In my opinion, it is an ugly workaround.

  In this example, the same control is present in 2 places, both in the .exe and the .llb

  -Perhaps you are missing the point - whether moving the LLBs in the folder with the file EXE solves the problem, then the point is NOT that there is a fix, the point is that something in the LLB is NOT available in the EXE file.

  If it is a CONTROL, then maybe it's a TYPEDEF control ' ed, and perhaps the possibility of DISCONNECTING the DEFINITIONS of TYPE kills you.

  (I've recently been thru this in a RTEXE, so it's all fresh for me):

  error: wait before create primary expression '.' token

  To work around, I want to load the data source and model of QML function, but this function must be called those the network connection has data extracted and stored in the file.

  Hel me please on this...

  You must give a signal of c ++ and set up a slot in qml connect.

  Example:

  C++

  mQmlDocument->setContextProperty("_myClass", myClass);
  

  emit mySignal()
  

  QML:

  _myClass.mySignal.connect(doSomething);
  
  function doSomething() {
      // logic here
  }
