• Separating the main.qml in .qml different files, is more pushed page

  Hi all

  My main.qml became very long (NavigationPane with a Page with a container with a label and ListView and a certain objects attached) and I started to break up.  Before that, when I chose a line in the list, it pushed successfully to the details of the page.  However, when I copy and pasted all within the Page to another qml file that I put in main.qml as object, it is more pushed the detail of the page.  I can't for the life of understand me. I saw / experienced with numerous examples of applications where he worked (Battambang in particular), but cannot see a difference between my folders and those.

  Some superfluous code (user interface format stuff) has been removed. I did essentially the same thing with the grid list Basic project template.  Help, please!  My only guess is that perhaps he does not know which is the data model, once he is out of main.qml. Is there something in c ++ I have to do or something I should even in the QML?

  There is no runtime error and the app loaded successfully, with the only problem being that when I click on a list item, there is no response/transition to the details page.

  However, I found a solution of mine.  I pushed my detail view using a function that is called in the onTriggered signal in the list. Copy the following code is a basic example of what I mean I did simply by separating the code of the project template "grid with details view:

  //main.qml
  // Grid view with detail project template
  import bb.cascades 1.0
  
  NavigationPane {
      id: navigationPane
  
      firstPage: MainPageContent {}

              id: secondPageDefinition
              source: "DetailPage.qml"

      ]
  
      function setDetailItem(item) {
          // show detail page
          var page = secondPageDefinition.createObject();
          page.text = item.text
          page.image = item.image
          navigationPane.push(page)
      }

• A generated within a loop in a subvi output data can be transferred to the main program for each iteration of the loop?

  Hi LV users,.

  I have a very basic question, I have not succeeded to asnwer using basic considerations.

  I made a sub - vi that performs a scan of current-voltage using a unit of measurement-source Keithley and a loop FOR.

  The subvi outputs 2 tables with my data (essentially an array of voltage and the corresponding current table). I also defined a Terminal at the exit of a group of these 2 tables in order to plot a graph XY - output. Specifically, I indexed this cluster to update after each iteration of the loop FOR, in my sub - vi (the indicator is placed outside the loop, of course).

  My problem is that I want my main program to display the XY-graph in real time, with an update after each iteration of the loop FOR which is in my sub - vi.

  I have a problem because my sub - vi output terminals are available for the main program concluded as soon as the sub - vi has completed its own execution (which is what we expect of sub - vi to do).

  How can I use a sub - vi (because it's handy) and get in the main program in the course of its performance data that are generated from the loops of sub - vi?

  Thanks in advance for your help,

  Yoyo87

  Elements of the queue in the Subvi them put your main VI where you want to display the data and the.

  It is similar to the architecture of producer/consumer. There are examples of it in LabVIEW. The examples work with 2 parallel loops, in your case a loop (the producer) will be in the Subvi.

• can't get to the main menu with my remote

  Hi guys, someone throws forward? I have a main menu and 3 menus of scenes.  When I hit the "menu" button on my remote, it goes to the menu stage 1.

  I created a certain projects until now and my remote worked well with them.

  But on this project, in every single scene menu, if I hit the top menu, it goes to the menu stage 1.

  I have reviewed my settings and can't seem to find where this fact is somehow indicated on my project. IF I don't reach my "main menu" button it will go to the main menu.

  Thanks for any help! very much appreciated.

  NAVE

  Now, how can I change these?

  Here's my menu with the Routing button:

  

  Note this button number 6 titled "gravity" is followed by the key #7 "I had my mom.  He is one who WILL not arrow down. So if I'm on "gravity" and "arrow down", it goes to the "funkytown" and refuses to go to "I got from my mom.

  To change this, first select the menu in the project Panel and now in the properties panel, uncheck the "Automatically Route buttons" in the properties of the menu.

  Now in the figure above, you will see that the mouse pointer becomes a hand icon when you hover over any number of the rectangle button number.

  Simply drag the desired number and you're done.

  For example, in your case, to go to the #7 button when you press the #6, go to the reduction in the rectangle of the #6 key and drag and drop it to number 7.

  Then, you'll see that the rectangle button # 6 number 7 instead of the number 8 (which is in the figure right now.)

  Do this for each button.

  Good luck.

  Thank you

• Can we push through the BES/MDS to a server outside the company application?

  Hi, we are developing a cloud-based management platform web mobile device for businesses. If the push initiator server would be located on our enterprise network or data centers, and it will not be inside the company of any particular network. In this case, our server in the cloud could still push the unit to a company through their Server BES/MDS?  I guess that the SDM cannot be accessed from outside the company, but somehow I could not a confirmation of research.

• Push all the objects in a tablespace to another

  Hello

  on the 11g R2 (11.2.0.3)

  We need to move all the objects in one tablespace to another.

  Is this possible?

  How can we push all the objects of a logical disk space to a different tablespace?

  Thank you.

  Generate the

  ALTER TABLE TableName MOVE TABLESPACE new_tbsname
  and

  ALTER INDEX REBUILD new_tbsname IndexName

  orders.  You can use "SQL Generation of SQL" or write a PLSQL WHERE USER_SEGMENTS loop.

  If you have some LOBs you must move the LOBs using
  ALTER TABLE TableName MOVE LOB (lobname) STORE AS LOBSEGMENT (TABLESPACE new_tbsname)

  I get in homepage.cpp root is not declared in this scope. I want to click on the main.qml button, I go to new file c ++ and call homepage.qml

  Hello
  I highly recommend investing a few weeks in learning C++ before learning the stunts. Specifically, these topics:
  -Advance declaring types
  -Memory management
  -Classes & inheritance (different from Java, a lot)
  -Life management object qt (parent/child, order of destruction of object relationship)

  These are essential, but we can't really help with them in the form of forum.

  On the compile error, this should probably fix:

  Homepage * home = new HomePage (NULL);

  But there are other problems in the statement of homepage. It's the manufacturer probably shouldn't take an instance of class ApplicationUI as the parameter.

  Engine QML use a JavaScript interpreter.

  that statement is bug in Qt 4.8, so it is better to avoid it or explicit use of braces {} in the case branches. Other than that, it is simply JavaScript.

• Windows 7 Internet on the main office/main screen being blocked please help

  For some reason any Windows 7 does not allow programs download from the internet. Programs (Adobe Digital & OverDrive Media are the two main) used to be able to download, but they no longer work. I've placed on the green list to come through the fire wall and I'm not running on a proxy server. I'm at a loss as to why he worked for years and now he's no longer. I tried the two patches that were given for both programs and nothing has worked. For Overdrive Media I get the answer that it is not connected to the internet and to digital Adobe, I get a different error that I looked and it said that the program could not through the firewall, changed cela setting and still have the same error. I also used to get the tab accu-weather on the top of the scree, but now he tells me that I am not connected to the internet. But clearly, I am as I am typing this question. Even gadgets that provides windows that can be placed on the main screen, like a clock and weather report that they are unable to connect to the server, that's why I think that it is not the firewall that is causing this problem I tried to disable the firewall and Windows program and I still have the same question. We did not have any changes made to our Web server or provider and the internet seems to work fine as well. I have also just finished a computer virus scan to determine if there is a problem here and nothing came. I tried to unplug the router to reset my IP address and that did not help. Any suggestion would be great.
  Thanks in advance for any help

  Hello

  A lot of programs in a Windows 7 computer that depends on the connection to the internet are controlled by settings of Internet connection in the computer. We can access these settings by going to Internet Options of Internet Explorer.

  You can check if your Internet Explorer is set to work offline?

  You can check that by following these steps:

  1. open Internet Explorer.

  2. Once Internet Explorer is open, press Alt and F together on your keyboard keys.

  3. make sure that the work offline option is not selected in the drop-down menu that appears.

  If your problem is still there, you can check these settings once:

  1. press the Windows and R keys on your keyboard to open the run box.

  2. in the run box, type inetcpl.cpl and press enter on your keyboard. This should open the Internet Properties dialog box.

  3. click on the connections tab.

  4. then click on LAN settings.

  5. make sure, none of these options in the local network settings are selected. If none of these three options have been selected, please deselect the and click OK.

  Now please check whether or not your gadgets and other programs that had the issue work.

  I hope this information helps you. Please respond with the status of the issue so that we can help you further.
