• Numbers in the textfield using the Boolean and structure of the case?

  Hello!

  I am very new to these forums and LabVIEW in general. I am currently trying to implement a calculator-ish, but without the operations (+ - * /).

  I have 10 Boolean buttons named 0-9, and with them I want to basically write a sequence of numbers in a textfield. I managed to solve the problem using a structure of the event, but now I would get the same result using a case instead of this structure. The problem is that I can't identify which button was pressed, so I can't make the program go to the proper case (0 to 9). Is there a simple solution to what you guys could help me with? Perhaps a property node that is generic for each button? I do not know

  in any case, I enclose you a simplified version of what I am seeking to achieve, withouh code I do not know how to write of course.

  Thanks for your help in advance!

  Here's a way to do it: combine Boolean values in a table, which become an 8-bit number and which thread to a structure to deal with a Boolean radix

• Waterfalls in the TextArea or TextField bug

  TextArea or TextField has slot as onTextChanged (QString string). If I put a symbol '. 'or', ' before the text in the input field, then when this slot will trigger, the text parameter will be empty string. I think it's a bug. Version of the sdk is 10.2. Have someone has experienced this problem and how can I solve this problem?

  Given that hintText works oddly, it is a prototype of bad

    Label {
        id: myTextHint
        visible: myText.text.length > 0
        bottomMargin: 0
        translationX: ui.du(2)
        textStyle.color: Color.create("#999999")

        hintText: "Subject"
        backgroundVisible: false
        onTextChanging: {
            myTextHint.visible = text.length > 0

• How to increase the size of the font of the TextField?

  Hi everyone, one question seems stupid, but I found no solution. I have a TextField and I want to increase the size of its police, but I can't. Looks like it has a maximum default font size, I can not change, the largest size of it seems to be 15pt, but I want to double this size. I have recently become familiar with developing applications on the BB, I think some of them the real problem is stupid, please help me, thank you very much.

  TextField {}

  ID: tx

  clearButtonVisible: false

  Input.Flags: TextInputFlag.VirtualKeyboardOff

  text: "ddddd".

  inputMode: TextFieldInputMode.Text

  preferredWidth: ui.du (60.1)

  preferredHeight: ui.du (60.1)

  textStyle.fontSize: FontSize.PointValue

  textStyle.fontSizeValue: 40.1

  {textFit}

  maxFontSizeValue: 100

  }

  }

  There is a very ugly way using scaleX and scaleY

  Give InputControl an id (in main.qml), for example someId.

  Access the variable an alias like someId.stext

• problems with application to a textfield focus

  It comes to the page, what am I doing wrong?

  Signal custom to notify that this page should be closed

  ID: cityfield
  hintText: qsTr ("enter city or Postal Code") + Retranslate.onLocaleOrLanguageChanged

  }

  }
  onAppSceneChanged: {}
  This triggers the update if the stage of the application is set to
  This Page QML.
  cityfield.requestFocus ();
  }
  }

  Do you want the text field to get the focus (and pull up the virtual keyboard on Z-devices) as soon as the page is loaded?

  Try to create a property on the qml page:

  property bool showVKB: false
  

  And add this method in your qml:

   onShowVKBChanged: {
          if (showVKB) {
              // This focus request shows the VKB if the Page is created via a ComponentDefinition (see main.qml)
              tfWord.requestFocus();
          }
      }
  

  And then, in your qml page that drives this page, set the showVKB property:

  navigationPane.push(page);
  page.showVKB = true;

  Hello

  Can someone tell me what I'm doing wrong here?  I want text large enough to read, but it's true lower case.  I'm just playing make a primitive text editor and I started with the code in the page Web Adobe FileReference.

  Thank you

  Hey harry,.

  change this line:

  MyTextField.setTextFormat(C_format);
  

  This line:

  MyTextField.defaultTextFormat = C_format;
  

  that should do the trick even if I can't use my keyboard on my laptop for some reason any... works only if I type with the integrated keyboard.

  Edit: I forgot to put the explanation hah... defaultTextFormat property applies the format of text of w/e tell you him AGAIN all text entered in the field. the setTextFormat method applied the text of w/e format that say you the CURRENT text in the field.

• TextField, submitted using c ++ does not

  Hi all

  I am trying to connect to the TextInputProperties::submitted(bb::cascades::AbstractTextControl*) signal, but in fact it does not. This is my code:

  TextField *inputField = uiPage->findChild("damageInput");
      QObject::connect(inputField->input(),
              SIGNAL(submitted(bb::cascades::AbstractTextControl*)),
              this,
              SLOT(onSubmitted(bb::cascades::AbstractTextControl*)));
      inputField->input()->setKeyLayout(KeyLayout::Number);
  

  I see no error on the console. In any case my events onSubmitted method is never called, even if it is declared as a crack:

  public slots:
      void addClicked();
      void subtractClicked();
      void onDialogFinished(bb::system::SystemUiResult::Type );
      void onSubmit(bb::cascades::AbstractTextControl *);
  

  I did something wrong?

  The only mistake I found on the log of the device is that:

  Dec 09 11:10:54.807 com.example.MagicManager.testDev_agicManageref1201b1.237248764... 0 csuifw_error ERROR ClientObject::removeAttributeListener() 15555 - recorded none of these headphones attribute on object

  But I don't know if it is related to my problem. Any idea?

  In theory, it is not strictly necessary,

  I tried to add the name with the same result.

  In any case, I found the problem, whas my fault.

  in fact in the connection, I stated as a crack the onSubmitted method events:

  QObject::connect(inputField->input(),
              SIGNAL(submitted(bb::cascades::AbstractTextControl*)),
              this,
              SLOT(onSubmitted(bb::cascades::AbstractTextControl*)));
  

  But the crack in the class's onSubmit:

  void onSubmit(bb::cascades::AbstractTextControl *submitter);
  

  Then, to fix this problem, solved the problem. Unfortunately this kind of errors is not recognized by the compiler.
