[SOLVED] Conversion from ascci to char in QML

[Pradeep Kumar]

@p3c0

Thank you it worked,,

but when i press caps lock depending on capital "P" or small "p", it has to print,
but for caps or small im getting "P" itself

my code:

Keys.onPressed:
{

        if(event.key === Qt.Key_P)
        {
            console.log("zero is pressed"+String.fromCharCode(Qt.Key_P));
            textin.insert(0,String.fromCharCode(Qt.Key_P))
        }
    }

textin is id for textinput;
help me

@Pradeep-Kumar.M Because it doesn't distinguish between them. Here's more info. You will need to use event.text as described in combination with modifiers I guess.

[p3c0]

@Pradeep-Kumar.M That being said you don't need conversion at all. Just use event.text for getting exact character and then insert. Just watch out for other key press (like shift or caps lock) which you will have to ignore.

@p3c0
Keys.onPressed:
{

        if(event.text)
        {
            console.log("zero is pressed");

            textin.insert(0,String.fromCharCode(Keys))
        }
    }

is this code k,
because when i press any keys its getting printed in application output

but i need in text input.

[p3c0]

@Pradeep-Kumar.M No conversion required now. Try

Keys.onPressed:
{
    textin.insert(0,event.text)
}

@p3c0

its working fine, thank u for that,
but in text input, its not appending, its getting from right to left, i want from left to right.

[p3c0]

@Pradeep-Kumar.M Are you using Arabic language or Arabic locale ? In that case it will be aligned to right side.

[Pradeep Kumar]

@p3c0

no, in text input its printing, which ever key is pressed, but not in appending fashion

ex: if i press 1234567890abcdefgh

its printing in text input as hgfedcba0987654321

i want in 1234567890abcdefgh

[p3c0]

@Pradeep-Kumar.M Ofcourse it will. You are inserting every new character at 0'th position.

[Pradeep Kumar]

@p3c0

so what to do if i want in appending fashion of letters, numbers, any other keys from keyboard, to text input

[p3c0]

@Pradeep-Kumar.M Get the new index position from TextInput. You want it to append it at the end so length should give you the last index. Insert it there

textin.insert(textin.length,event.text)

@p3c0

thank you, it worked.

[p3c0]

@Pradeep-Kumar.M You're Welcome :)

@p3c0

one more question

i tries Qt Integration

here is ex: of main.cpp

QQmlApplicationEngine engine;
engine.load(QUrl(QStringLiteral("qrc:/main.qml")));
QObject *topLevel = engine.rootObjects().value(0);
QQuickWindow *window = qobject_cast<QQuickWindow *>(topLevel);
window->dumpObjectTree();
QQuickWindow *window1 = topLevel->findChild<QQuickWindow * >(objectname);

can i have QQMLContext, QQMLComponent & QQMLEngine,
if so
can u provide code of it, along with component item.

[p3c0]

@Pradeep-Kumar.M Do you mean an example ?

[Pradeep Kumar]

@p3c0

yeah but
to replace the lines above which i sent in previous post

[p3c0]

@Pradeep-Kumar.M Here's an example.

[Pradeep Kumar]

@p3c0

for wat exactly setcontextproperty is used

[p3c0]

@Pradeep-Kumar.M To expose C++ objects to QML.

[Pradeep Kumar]

@p3c0

do we have QQMLContextItem or QQMLComponentItem
