Welcome to the group, @Santhosh252! :-)

Wanna share your story of how you started with Qt, QML or C++? Maybe some nice feature that made you stick with it.

For the record, setting height in the <img> HTML tag doesn't accomplish anything.

C++ & Qt

24 December 2025 16:36

So solution (a) is the one I'm trying right now with specifying width and height, but I would rather (b) have the widget determine its height. Any insights how to achieve that?

Happy Holidays everyone! - Question regarding rendering HTML in a QTextBrowser, and determining the required height of the widget.

I render some HTML in a QTextBrowser that inlines some external images (<img src="..."/>). That works fine. My general goal is for the widget to resize itself to its required size, so I set setSizeAdjustPolicy(QAbstractScrollArea::AdjustToContents). However, this does not work - the widget shows a vertical scroll bar.

Functor templates are not necessarily something to make your start in C++.

That’s more of a reference. Good for looking things up, but perhaps not as a textbook.

If you want a steep learning curve, read Stroustrup's book.

C++ & Qt

Do you have any c/c++ experience? Classic (pre c++11) books are quite heavy on pointers and iterators, which may scare some readers off.
You will still need to learn those things, but the learning curve is not as steep nowadays.

Bruce Eckel's book is good - his Java one is good too.. But I'm also going based on reading it 25ish years ago too...

There have been significant changes to the language since it was published (C++11 being the most significant) , so a newer one probably should be suggested - though the fundamentals would still apply - so you could probably get away with reading his book and supplementing with a book that goes into the changes added in C++11, C++14, C++17 and C++20.

I read Bruce Eckel's "Thinking in C++". It's free for d/l.

@shimarongreywolf What if you turn the scroll bars off and set setFixedSize to document ().size().toSize() on documentSizeChanged?

C++ & Qt

24 December 2025 17:16

No, this does not work. Thanks anyway. I'll post a solution if I find one.

Happy holidays!

ChatGPT proposes this (but I haven’t verified):

QTextBrowser *browser = new QTextBrowser(this);
browser->setSizeAdjustPolicy(QAbstractScrollArea::AdjustToContents);
browser->setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
browser->setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOff);

// Important: constrain text width so height can be computed
browser->document()->setTextWidth(browser->viewport()->width());

// React when images change the document size
connect(browser->document()->documentLayout(),
&QAbstractTextDocumentLayout::documentSizeChanged,
browser,
[browser](const QSizeF &) {
browser->updateGeometry(); // notify layout system
});

C++ & Qt

24 December 2025 16:35

My guess is that this is due to the image being inlined and no width/height being specified.

Hi all! Has anyone tried to deploy the qt/qml environment in manjaro for Android development? Can you share the installation steps? When sdkmanager --list produces the following: Caused by: java.lang.ClassNotFoundException: javax.xml.bind.annotation.XmlSchema

He did write a shorter overview of new c++ features a couple of years ago though

But that was, I dunno - 25 years ago or so. There's probably better ones out there.

You guys have some good books to begin with c++?
