• Get the text of a button when it is read as a node. VBox loop

  I learn JavaFX, and it's just a small matter of programming.
  
  I have 3 buttons in a VBox. And I want to apply the same 3 effects on all of the buttons after I put them in the Vbox. But when I use a loop and getChildren() on the VBox, they are returned as "nodes". I can't use Button.getText () to find the text of the button.
  
  Is there a way I can getText to a node? Or maybe convert the current node to a button and get the text in this way?
  
  VBox, vbox = new VBox();
  
  Option 1 button = new Button ("first button");
  
  Option 2 button = new Button ("Second button");
  Option3 button = new Button ("display rules");
  
  vbox.getChildren () .add (option1);
  vbox.getChildren () .add (option2);
  vbox.getChildren () .add (option3);
  
  for (button end node: vbox.getChildren ())
  {
  button.setOnMouseEntered (new EventHandler < MouseEvent >)
  {
  @Override
  public void handle (MouseEvent arg0)
  {
  button.setEffect (addEffect (Color.web("#53CFA6"),.8, 10));
  }
  });
  button.setOnMouseExited (new EventHandler < MouseEvent >)
  {
  @Override
  public void handle (MouseEvent arg0)
  {
  button.setEffect (addEffect (Color.web ("#FF6800"),.8, 10));
  }
  });
  
  button.setOnMouseClicked (new EventHandler < MouseEvent >)
  {
  @Override
  public void handle (MouseEvent arg0)
  {
  button.setEffect (addEffect (Color.web ("#E62800"),.8, 10));
  
  To do button.getText)
  Button; button.getText (work)
  
  
  }
  });
  }

  Hello user,.

  You must have formatted your code correctly. See the forum guides for formatting codes.

  To get the instance of the button, you need to do it safely
  There are two ways to get the instance of the Button.

  for (final Node button : vbox.getChildren()){
       Button b = null;
       if(button instanceof Button){
            b = button;
       }
  
       if(b != null){
            //Do your stuffs here
       }
  }
  

  Or you can even do like that too

  for (final Node button : vbox.getChildren()){
  
       Button b =null;
       try{
            b = (Button) button; //casting the class
       }
       catch(ClassCastException e){
            e.printStackTrace();
       }
  
       if(b != null){
            //Do your stuffs here
       }
  }

• get the text of a button on alertdialog

  Im trying to find how to discern what button is pressed in the alertdialog and I can't seem to find how do exactly... anyone knows?

  Hey,.

  You can use the selectedIndex property of the alert dialog class to get the index of the button that has been pressed - the first button showing would be 0 then 1 then 2 etc.

  Here's more information:

• How can I get the text value of an element XML in MXML?

  Hello

  
  

  I have the following XML loaded into a variable of XML type:

  Properties of <>
  the RIMpro data collector Configuration < comment > < / comment >
  < key="server.pear.username"/ entry >
  < key = "enter server.apple.retry.times" > 5 < / entry >
  < Enter key = "rdc.proxy.host" > http://192.168.1.2:8080 < / Entry >

  /Properties >

  I can easily get the key attribute displayed in a DataGridColumn by setting the dataProvider my variable and the data in "@key" area  But I don't know how to get the text value in a second column...  Is it possible or do I have to change my XML to something like this:

  Properties of <>
  the RIMpro data collector Configuration < comment > < / comment >
  < key="server.pear.username"/ entry >
  < key = "enter server.apple.retry.times" value = "5" > < / entry > "
  < Enter key = "rdc.proxy.host" value ="http://192.168.1.2:8080"""> < / entry > "

  /Properties >

  Thanks in advance.

  Yes, you'd better change your XML structure to fit the internal mechanisms of the DataGrid.

  As model dataField require each element of the grid line to have a named property to display, otherwise you will be forced to overcome this model to the custom help labelFunction for the particular column that will implement your custom actions on how to extract the appropriate data for this column of the grid line item. It will be much more complicated that just reorganize your xml structure.

• How to get the text in a dynamic text field?

  Hello

  I would like to get the text in a text field I have on stage and put it into a string. I do this because I don't don't want to use the table to store each letter I click. Is this possible?

  Concerning

  you don't know.  You can use the text property of your textfield object and store that value in a variable.

  You can use a click on a button to trigger this code or change event of the textfield or any number of other triggers.

• How to get the text of a SystemPrompt (Cascades)

  Hello

  I've been struggling with this for a few hours now. I followed the example of "dialogues" on github, so I have successfully created a SystemPrompt (the dialog box that allows the user to enter text and accept / reject). Curiously, in this example there is no use of user text input. Do you know how to get the text in my QML? Here you have an example of code that I use:

  My QML:

  // Default empty project template
  import bb.cascades 1.0
  import bb.system 1.0
  
  // creates one page with a label
  NavigationPane {
      id: navigationPane
      Page {
          attachedObjects: [
              SystemPrompt {
                  id: prompt
                  title: qsTr("Enter a text for the label")
                  modality: SystemUiModality.Application
                  inputField.inputMode: SystemUiInputMode.Default
                  inputField.emptyText: "Label text..."
                  confirmButton.label: qsTr("Ok")
                  confirmButton.enabled: true
                  cancelButton.label: qsTr("Cancel")
                  cancelButton.enabled: true
                  onFinished: {
                      if (result == SystemUiResult.ConfirmButtonSelection) {
                          lab1.text = ????? // Here is where I don't know what to do
                      }
                  }
              }
          ]
  
          Container {
              layout: StackLayout {}
  
              Label {
                          id: lab1              text: "Label text"
                  objectName: "lab1"
                  textStyle.base: SystemDefaults.TextStyles.TitleText
                  horizontalAlignment: HorizontalAlignment.Center
              }
  
              Button {
                  text: "Update label"
                  horizontalAlignment: HorizontalAlignment.Center
                  topMargin: 150.0
                  onClicked: {
                      //_appUi.editLabel();
                      prompt.show();
                  }
              }
          }
      }
  }
  

  Be sure to add this in your .cpp file or all of app:

  #include 
  #include 
  #include 
  #include 
  #include 
  #include 
  #include 
  #include 
  #include 
  #include 
  

  and don't forget to include them in your app .cpp file (probably not all are needed, but just in case I leave here for the moment):

  qmlRegisterType("bb.system", 1, 0, "SystemUiButton");
      qmlRegisterType("bb.system", 1, 0, "SystemUiInputField");
      qmlRegisterType("bb.system", 1, 0, "SystemToast");
      qmlRegisterType("bb.system", 1, 0, "SystemPrompt");
      qmlRegisterType("bb.system", 1, 0, "SystemCredentialsPrompt");
      qmlRegisterType("bb.system", 1, 0, "SystemDialog");
      qmlRegisterUncreatableType("bb.system", 1, 0, "SystemUiError", "");
      qmlRegisterUncreatableType("bb.system", 1, 0, "SystemUiResult", "");
      qmlRegisterUncreatableType("bb.system", 1, 0, "SystemUiPosition", "");

      qmlRegisterUncreatableType("bb.system", 1, 0, "SystemUiModality", "");
      qRegisterMetaType("bb::system::SystemUiResult::Type");
  

  Thank you very much

  If you look very carefully by the docs, you'll trip over https://developer.blackberry.com/cascades/reference/bb__system__systemprompt.html#inputfieldtextentr...

  So, replace your? with inputFieldTextEntry() and you will get the text you need.

• Get the text in the Edit field

  Hello

  In my Application, I add a check box and a label field and a field change a grid field Manager. Then this network domain manager, I add several times in Vertical field Manager. So it's looking like list of items. Now, when I checked the box five, trying to get the text of the corresponding edit field.

  This is the code for the domain network manager:

  int c[] = {screenWidth/6, (screenWidth)/3, (screenWidth)/2};
          gm = new GridFieldManager(c, Manager.VERTICAL_SCROLL);
          Logger.out("Grocery", "Here it is coming"+i);
          cbfChecked = new CustomCheckBoxField();
          cbfChecked.setChangeListener(new FieldChangeListener()
          {
              public void fieldChanged(Field field, int context)
              {
                  if(checked[i] == false)
                  {
                      checked[i] = true;
                  }
                  else if(checked[i] ==  true)
                  {
                      checked[i] = false;
                      Logger.out("Grocery", "It is UnChecked" +checked[i]);
                  }
              }
          });
          gm.add(cbfChecked);
          Logger.out("Grocery", "Adding first Label Field");
          LabelFieldCustom lfFrom = new LabelFieldCustom((String) m_vtrItems.elementAt(i),Color.BROWN,FONT_FAMILY_0_SF_AS_16,Field.FIELD_LEFT);
          gm.add(lfFrom);
          Logger.out("Grocery", "Adding second Label Field");
          efcAmount = new EditFieldCustom(Bitmap.getBitmapResource("dob_text_box.png"), 25);
          efcAmount.setMargin(new XYEdges(30, 0, 0, 0));
          gm.add(efcAmount);
          return gm;
  

  Here I add the grid domain manager several times:

  for (int i = 0;i < m_vtrItems.size();i++)
          {
  
              vfm.add(getRow(i));
              vfm.add(new SeparatorField(SeparatorField.NON_FOCUSABLE));
  
          }
  

  Here is the snapshot of my screen:

  Please help me.

  You can access the field by index (prone to errors if).
  or you could save your fields in a data structure, such as a hash table, with the checkboxfield as key to the editfield as value.

• Cannot get the text in the field description flex

  Hi all
  
  I try checking if a field flex text value contains anything or not. IE, this flex field is a mandatory field and I need to check when running.
  But I can't get the text value of the descriptive flex field written by the user at run time.
  
  OADescriptiveFlexBean oadescriptiveflexbean1 = (OADescriptiveFlexBean) webBean.findIndexedChildRecursive ("PerfRatingFlex");
  If (oadescriptiveflexbean1! = null & & oadescriptiveflexbean1.isRendered ())
  {
  String revision = (String) oadescriptiveflexbean1.getAttributeValue ("ATTRIBUTE12");
  }
  
  I can't retrieve any value of variable revizeNedeni. I tried a few combinations of such use, and I searched the forum for this problem and I tried these suggestions. But I failed.
  Could someone give me some examples of specific code for this?

• How to get the text have the same effect as the video?

  Hello

  For the first time post here, but I wonder how to get the text of the titles have the same effect as the video behind her.

  For my video, I use 'bad tv' and other effects such as Gaussian that obviously changes the appearance of video, creating the look of VHS. However, I then inserted text via the title, but it normally appears. How can I make this text have the same effects as the video behind it?

  A friend told me I might need to add text to the video first, then do the effects, I have not tried, but wonder if there is an easier way, as this would require me to restart.

  EDIT: That's what I'm looking for. https://youtu.be/7_2PHQI89dI?t=24s The text has the same effect as the video.

  Thank you

  One way is to create a clip made up based on the title and the original clip. Then apply the effect.

  Another way is to use an adjustment layer.

  Good luck.

  Don't know how to get the exact button back (sorry) I dig around too much to do...
  But! Today, I found by chance that by clicking and holding on the back button the same box to popup in last-12-sites and you can stream on the list to return to that particular site.

• How can I get the max of a measurement value

  How can I get the max of a measurement value?

  http://forums.NI.com/T5/LabVIEW/how-can-I-return-the-maximum-value-from-a-voltage-sensor-over/m-p/30...

  I tried the while loop max-min-solution described in this link. But this using my myRio acceleration measurement no longer works. It seems to hang.

  I use the I2C Communication.

  

  The inner circle while loop is a bad construction.  It will be either executed once, if enter the Boolean value is True, or forever if the value is false.

  Put your records on the timed loop shift and eliminate inside while loop.  Then your code should work.
