@JonB that answer is from 5 years ago, I had read it but had hopes something had changed.

So the answer is still NO.

At the end I've researched again the view's transformations and concluded to support both features and warn for the complexity.

I did not re-implement the add/remove items of the scene together with a group. Thanks for the hint @Asperamanca .

A colleague of mine, that used Qt for years, helped me.
The culprit was (other than me) that I wrongly created the parent of the children.

@jsulm Thank you very much !

It's exactly what I needed.

In the top !

@Krakenus00 Hello can you add the picture that you want to achieve and one that you are getting

SetMinimumSize() does not work for me. I think it is because I change the window's position. However, the problem was in my form file. For an unknown reason, it changed the window's size to 802x600 when I was checking for 800x600. Maybe there was some another way out, but now all works just fine.

@Nathan-Barel
Yes it seems fixed in 5.12 and 5.15

To solve the VCINSTALLDIR problem, start the command prompt from your start menu -> Visual Studio 2017 -> x64 Native Tools Command Prompt (be sure not the ones with x86)
Then call :
set PATH=C:\Qt\5.14.1\msvc2017_64\bin;%PATH%
to make both vc and qt dirs in your PATH. To force deploying the release binaries, add --release after windeployqt.

Here is the code.

QList<SomeClass> ModeTableEntries ; for (int row = 0; row < ModeTableEntries .length(); row++) { ui->EntriesTableWidget->insertRow(row); ui->EntriesTableWidget->setRowHeight(row, 45); ModeValues value = ModeTableEntries [row]; QTableWidgetItem* currentItem = new QTableWidgetItem(value .ModeText); if(TestModeEnabled == true) currentItem->setCheckState(Qt::Checked); else currentItem->setCheckState(Qt::Unchecked); ui->EntriesTableWidget->setItem( row, 0, currentItem); currentItem->setFlags(currentItem->flags()^(Qt::ItemIsEditable )); }

The problem is that I cannot style the default implementation of the QTableWidgetItem(QCheckbox) that is part of the QTableWidgetItem.

@vicky_mac

A QStackedWidget works like a book. You have pages with your content. You can flip these pages to change your widget inplace (without opening another window or something else).
So one possibility is to put one of each QTabWidget (each with a different tabBar position) on a page of a QStackedWidget. You could flip the pages by clicking a dummy tab on each tabBar or you use a button to go to the next page. I know, this is not exactly what the widget in your image looks like :)

@vicky_mac said in How to Add multiple Qtoolbar in QtabWidget:

Haven't used QT much

If you want a widget, that looks exactly like the one shown above, you could still try to subclass and create your own, custom TabWidget, but I fear, that it might be a little too challenging.

Here's all you need to know about QStackedWidget (https://doc.qt.io/qt-5/qstackedwidget.html#details)

Hi
As far as I know, there is nothing like that in Qt. It can blur widgets but not the actual desktop.

UPD:
I write this method for drawing, looks good

{ QLabel::paintEvent(event); QPainter painter (this); painter.setPen(Qt::green); painter.setBrush(palette().windowText()); painter.setRenderHints(QPainter::Antialiasing | QPainter::TextAntialiasing); painter.setFont(font()); QRect font_rect = painter.fontMetrics().boundingRect(text()); QRect label_rect = contentsRect(); label_rect.adjust(margin(), margin(), -margin(), -margin()); int dx = label_rect.width() - font_rect.width(); int dy = label_rect.height() - font_rect.height(); int x = 0; int y = 0; if (alignment() & Qt::AlignLeft) x = label_rect.left(); else if (alignment() & Qt::AlignHCenter) x = label_rect.left() + dx / 2; else if (alignment() & Qt::AlignRight) x = label_rect.right() - font_rect.width(); if (alignment() & Qt::AlignTop) y = label_rect.top() + font_rect.height(); else if (alignment() & Qt::AlignVCenter) y = label_rect.top() + dy / 2; else if (alignment() & Qt::AlignBottom) y = label_rect.bottom(); QPainterPath path; path.addText(x, y, font(), text()); painter.fillPath(path, palette().windowText()); painter.strokePath(path, QPen(QColor(255, 0, 0, 50), 2)); }

But i still dont understand the difference btw native paint event and my own

@Faruq
QML (using Canvas element) and QtQWidgets (using QPainter in combination with QPainterPath) is capable of drawing such things.
In either way it's all about the math and doing the calculations of each shape (arcs, lines, texts, ...)
The bottom image is rather easy. Yyou just need to calculate the translation along the x-axis based on your input values which make up the direction.

Don't @ the moderators unless you have an issue requiring moderation.

Depending on the content of your line edit, you can use toLatin1() or toUtf8() rather than making these two conversions.

Thank you all, the issue is solved.

@goldstar2154 Totally agree with you - there is a obvious bug. But thanks to @raven-worx 's code we've got a way to get a result at least. And "solved" will help in web search:)
Thank you very much for this question:)
