SpinBox up and down indicator not positioned as expected - qt

According to the docs for SpinBox indicators are placed on the left and right of the value itself.
So this code:
SpinBox {
value: 50
}
Should give this output:
Now when I run this on Manjaro with Qt 6.2.3 I instead get this output:
Why It does not show what is expected like in the docs?
Do I need to override up.indicator / down.indicator to change the whole style?

To get this output you should be using version >= 2.0 of QtQuick.Controls.

css is not rendered properly

I'm trying to build a progress bar component where I want to achieve a specific design for that, as you can see how I tried it in this codesandbox link:
https://codesandbox.io/s/determined-lamport-7zjvwj.
I want to achieve the following behavior:
Initially, all dots should be blue except the first one which is rounded in blue.
I want to keep the dots in the progress bar when I change the properties into blue if the percentage didn't cover them otherwise white
But somehow my CSS calculation is not working properly as expected which I believe I missed something, so any ideas?
there is an error in line 60 et 61
const current = steps.indexOf(stepStatus); // issue here probably
const step = steps.indexOf(stepStatus); // issue here probably
should be:
const current = steps.indexOf(progressBarStatus);
const step = steps.indexOf(stepStatus)
In addition to this problem the width of the pourcentages is not accurate, you can fix this by changing the line 51 with:
const progressBarCalculatedWith =
((current / (getIntermediarySteps + 1)) * 100) + (steps.length -1 - current);
this is the result :
working progress bar
Simply use the same calculation that calculates the % for the loading bar, then apply it ont he dots - So that if the value is 25% or more, then the first dot is blue, then an additional 25% and so on etc. It does not have to be interconnected with the rest of the loading bar, it can use the same calculation.
Simply an If / Else basically.

Adjust QTableView Height to its content (few lines)

Below a screenshot of my application. I want to get rid of the white spaces after the last tables lines marked by red rectangles :
The horizontal size policy is expanding and the vertical one is minimum and for other tables it is both set to expanding.
I'm using this method I found in another SO question but as you can see the result is not flawless.
void verticalResizeTableViewToContents(QTableView* tableView)
{
tableView->resizeRowsToContents();
// does it work ?
tableView->setSizeAdjustPolicy(QAbstractScrollArea::AdjustToContents);
int rowTotalHeight = 0;
// Rows height
int count = tableView->verticalHeader()->count();
for (int i = 0; i < count; ++i) {
// 2018-03 edit: only account for row if it is visible
if (!tableView->verticalHeader()->isSectionHidden(i)) {
rowTotalHeight += tableView->verticalHeader()->sectionSize(i);
}
}
// Check for scrollbar visibility
if (!tableView->horizontalScrollBar()->isHidden())
{
rowTotalHeight += tableView->horizontalScrollBar()->height();
}
// Check for header visibility
if (!tableView->horizontalHeader()->isHidden())
{
rowTotalHeight += tableView->horizontalHeader()->height();
}
tableView->setMaximumHeight(rowTotalHeight);
}
Somewhere, I'm using this code to setup one of the tables :
m_Internals->Ui.Measures->setModel(mm->getPh66MeasuresModel());
m_Internals->Ui.Measures->horizontalHeader()->setSectionsMovable(true);
m_Internals->Ui.Measures->horizontalHeader()->setHighlightSections(false);
m_Internals->Ui.Measures->horizontalHeader()->setSectionResizeMode(QHeaderView::Interactive);
m_Internals->Ui.Measures->horizontalHeader()->setStretchLastSection(true);
m_Internals->Ui.Measures->verticalHeader()->hide();
m_Internals->Ui.Measures->setSelectionBehavior(QAbstractItemView::SelectRows);
verticalResizeTableViewToContents(m_Internals->Ui.Measures);
I'm using Qt ModelView pattern to populate/update the tables.
Update : I made a small example to reproduce this issue with QTableView : https://github.com/embeddedmz/QTableViewAdjustPolicyNotWorkingProperly
Using the latest Qt version (from Qt official installer), there's no issue. However, using the Qt library provided by vcpkg (outdated for sure) the issue is there.
With Qt provided by vcpkg :
With the latest Qt provided by the Qt Company (update not the latest, it's 5.12.11) :
If you have something fully buildable on Ubuntu 20.04 LTS, post a link to the complete project (strip it down to just this part) and I will take an actual stab at it.
My gut, having worked with Qt for years, is telling me you are being burned by Margins.
https://doc.qt.io/qt-5/qwidget.html#contentsMargins
You probably need to set a bottom margin of Zero.
https://doc.qt.io/qt-5/qmargins.html#setBottom
If you retrieve the margins for those widgets you will probably find they are non-zero.
you can also fix your problem with one trick, this problem happens for you because your data is lower than the table size. I clone your project and change sizepolicy
Under Qt 5.12.11, the bug does not exist. So I took a look at the QAbstractScrollArea::sizeHint code of this version and compared it with the implementation used in recent versions of Qt and found that setting verticalScrollBarPolicy to "ScrollBarAlwaysOff" the "AdjustToContents" adjustment policy works. The default value was "ScrollBarAsNeeded", in fact we can see that this value is not handled but since in Qt 5.12.11 we only compare the vertical|horizontal]scrollBarPolicy to Qt::ScrollBarAlwaysOn it prevents this bug from appearing.

How to get rid of the yellow highlighted background in old search text in Qt Creator?

I have searched for the string "as" a few hours before in Qt Creator.
However it seems to be still active and whenever I type "as" again it is highlighted automatically.
And I can't get rid of it.
It looks like this:
Do you know what could be the problem and how to remove the yellow highlight?
According to your comment, you are using FakeVim so you can set whether or not search results are highligthed in Qt Creator ( Tools > Options > FakeVim). And if you want to clear the highlighted results, just type :nohlsearch in FakeVim.
If you are using FakeVim you can set up a user command in Tools -> Options -> FakeVim -> User Command Mapping. E.g., User command #1 = ":noh". Then you can use 'Alt+V 1' to get rid of the yellow highlight.

Qt QML Settings are not saved/applied

I have simply copied this example from the docs, adjusting the import version number to the newest ones (but I tried with both for same result).
import QtQuick.Window 2.12
import Qt.labs.settings 1.1
Window {
id: window
width: 800
height: 600
Settings {
property alias x: window.x
property alias y: window.y
property alias width: window.width
property alias height: window.height
}
}
As opposed to advertised, the window geometry was not saved after I closed and reopened the window. In fact, it now doesn't show the window at all? (I tried re-running qmake and cleaning all)
I also get this warning every time I run the project in Qt Creator, regardless of whether I use Settings or not:
17:01:02: Starting C:...debug\untitled.exe...
QML debugging is enabled. Only use this in a safe environment.
qrc:/main.qml:10:5: QML Settings: Failed to initialize QSettings instance. Status code is: 1
qrc:/main.qml:10:5: QML Settings: The following application identifiers have not been set: QVector("organizationName", "organizationDomain")
1) Is the warning related to the issue?
2) How do I remove the warning?
3) How do I get the settings to be applied as advertised?
...Turns out I had to keep reading the docs to the end.
1) Warning is related to the issue.
2) Per the docs, add this at the beginning of the main in main.cpp
app.setOrganizationName("Some Company");
app.setOrganizationDomain("somecompany.com");
app.setApplicationName("Amazing Application");
3) Now works as advertised.

Console not showing up on Xcode Playground 7.1.1

This is what Standard Editor looks like:
This is what Assistant Editor looks like:
This is a problem because whether I click on the eye icon or the + next to (6 times), it shows me a graph only: I was wondering if there would be a way to show more useful output?
Edit: When I show the debug area, it doesn't show any output there:
You can access the console by the menu
View > Debug Area > Show Debug Area
There's also a little upper arrow icon in the bottom left of the Playground, and the SHIFT+CMD+Y shortcut.
In the console you will be able to see not only the error messages but also anything you print.
To be able to see the output in the preview panel you have to place the statement you want to see on a separate line, and break down the logic on separate lines up to some point.
In your case, for example:
let arr = [1,2,3,4,5]
let triple = arr.map({
(i:Int) -> Int in
return i*3
})
Here with let triple ... not being on the same line as the closure anymore, the Playground is able to preview it.
And by clicking on the + on the right side, you can now unfold the special panel where all values are visible:
