Keyboard focus. Bug in the documentation?



  • Hi there! I've read "Keyboard Focus in QML" in the documentation and noticed several bugs (or not).

    There is an example:
    @Rectangle {
    color: "red"; width: 240; height: 55
    Rectangle {
    color: "lightsteelblue"; width: 240; height: 25
    Text { id: myText }
    Item {
    id: keyHandler
    focus: true
    Keys.onPressed: {
    if (event.key == Qt.Key_A)
    myText.text = 'Key A was pressed'
    else if (event.key == Qt.Key_B)
    myText.text = 'Key B was pressed'
    else if (event.key == Qt.Key_C)
    myText.text = 'Key C was pressed'
    }
    }
    }
    Rectangle {
    y: 30; focus: true
    color: "lightsteelblue"; width: 240; height: 25
    Text { id: myText }
    Item {
    id: keyHandler
    focus: true
    Keys.onPressed: {
    if (event.key == Qt.Key_A)
    myText.text = 'Key A was pressed'
    else if (event.key == Qt.Key_B)
    myText.text = 'Key B was pressed'
    else if (event.key == Qt.Key_C)
    myText.text = 'Key C was pressed'
    }
    }
    }
    }@

    1. There are not unique ids (myText, keyHandler)
    2. In the documentation written that focus should get first rectangle, but really focus is located on second one.

    From doc:

    bq. In this case the first appearance of the Item::focus property being set to true on line 4 is selected, and the value of Item::focus in the other two instances is reverted back to false. This is exactly the opposite of what was wanted!

    Thanks, Kirill.





  • The reason for the duplicated ids is indicated in the text below the example:

    [quote]
    The right hand side of the example shows the expanded code - the equivalent QML without the use of the component MyWidget.
    [/quote]

    The code is a theoretical expansion of the code in the left column; it's not real, usable code.

    With regards to the focus being on the second rectangle, the docs above the example code states:

    [quote]
    Here we create two instances of our previously defined component, and set the second one to have focus.
    [/quote]

    so this seems ok.

    However if there are problems in the docs they should definitely be reported at http://bugreports.qt.nokia.com.
