QML MaximumBlockCount on TextArea

tuukkap

Hi,

I've linked below a discussion about maximum line count for textarea. Unfortunately I'm not able to define it for the TextArea. I'm not sure has something changed in the previous 2 years which makes it impossible to use maximumblockcount for TextArea nowadays or is it just that I don't understand something fundamental here? Could someone provide a simple example how it is meant to be defined?

Thanks in advance,
Tuukka

I presume this means you are using QtQuick.Controls 1.5 and not QtQuickControls 2.0 ?

I'm using QtQuick.Controls 2.3 but it might be that my issue might be that I don't understand what this sentence means:
"TextEdit should simply expose the maximum line count"

@tuukkap
I'm just quoting from your linked post:

When I switched from QtQuick.Controls 1.5 to QtQuickControls 2.0 the above issue was resolved and setting the maximumBlockCount of the underlying QTextDocument behaves as expected.

I have tried with different QtQuick.Controls versions and I can't get this to work with any of those which probably means that I'm doing something incorrect.

Given that thread says code should now work at QC 2.x, I think you'd best produce a small example of your code problem and post here, for others to comment on.

I somehow imagined it should be usable "simply" like below but MaximumBlockCount can't be used from textDocument at least like this:

        TextArea {
            id: ticketTextArea
            textDocument.MaximumBlockCount: 3
            Layout.preferredHeight: 150
            Layout.fillWidth: true
            Layout.maximumHeight: 200
            Layout.rowSpan: 3
        }

Thanks for your patience :)

I've never done QML, so I'll have to leave an expert to help you further...

BTW, textDocument.MaximumBlockCount --- is QML case-sensitive? Property name is maximumBlockCount.

Thanks for your help! Yeah, that starting capital "M" was mistake as I recreated the example but it doesn't work with "m" either.

const QQuickItem *rootObject = m_logWidget->rootObject();
m_logTextArea = rootObject->findChild<QObject *>("logTextArea");
const auto *quickTextDocument = qvariant_cast<QQuickTextDocument *>(m_logTextArea->property("textDocument"));
auto *textDocument = quickTextDocument->textDocument();
textDocument->setMaximumBlockCount(10);

Setting on C++ side works for me.
