@Luuk00101 said in Can't set the icon on the Windows build:

Do you think the path resolves to an invalid one on when we run it on Windows?

This is the first thing I would check.

Resource files: https://doc.qt.io/qtforpython-6/overviews/resources.html

@SimonSchroeder I doubt this library can help here. Can you please provide a minimal, compilable example in a bug report? I can take a look on it. Sounds similar to https://bugreports.qt.io/browse/QTBUG-122403 which needs a QIcon instead a QPixmap to make scaling work for your situation.

@Bonnie said in add EXE Icon:

Did you not make it?
Yes I did now :)

Thank you so much for your helping

IDI_ICON1 ICON "Resources/images/myapp.ico"

.rc file has been created by notepad

set(APP_ICON_RESOURCE_WINDOWS "${CMAKE_CURRENT_SOURCE_DIR}/icon.rc") if(${QT_VERSION_MAJOR} GREATER_EQUAL 6) qt_add_executable(MyApp MANUAL_FINALIZATION ${PROJECT_SOURCES} ${QM_FILES} ${APP_ICON_RESOURCE_WINDOWS} ... icon.rc )

@Saviz I guess the path of the svg file may not be right. Can you post your qrc file here?
do you use qmake or cmake?

TabButton { id: root implicitHeight: *** implicitWidth: *** contentItem: Label { anchors.fill: parent Row { spacing: Image { id: buttonImage height: root.height width: root.height source:svg file } Text { text: root.text height: root.height width: root.availableWidth color: "white" horizontalAlignment: Text.AlignLeft verticalAlignment: Text.AlignVCenter } } } }

Sorry for the very late reply, would it be possible to have a complete minimal compilable project to be able to test your issue ?

As explained here, QSvgWidget has been moved to a new module called QtSvgWidgets. According to the documentation:

Header: #include <QSvgWidget> CMake: find_package(Qt6 REQUIRED COMPONENTS SvgWidgets) target_link_libraries(mytarget PRIVATE Qt6::SvgWidgets) qmake: QT += svgwidgets Inherits: QWidget

So in Qt6 the solution is following:

QT += svgwidgets

@arjun98 said in How do you properly increase QLineEdit increase icon size/:

ui->searchbar->setClearButtonEnabled(true);
ui->searchbar->QLineEdit::addAction(QIcon(":/img/icons/icon_search.png"), QLineEdit::LeadingPosition);

I have tried loading icon to line edit using above code, it's clearly visibile. and image is not blurred.
try to experiment loading the icon to QLineEdit without any stylesheet being set to it.

Qt lottie might be an option. That's exactly its purpose

2 works, thanks!
But why 1 icon isNull() ?

Is possible 1 and 2 under Linux? Linux has something like mime or/and Elf binaries can holds icons?

Bad:

QPixmap extractMime(const QString &sourceFile) { QMimeDatabase mime_database; const QString nativeName = QDir::toNativeSeparators(sourceFile); QIcon icon; QList<QMimeType> mime_types = mime_database.mimeTypesForFileName(nativeName); icon = QIcon::fromTheme(mime_types[0].iconName()); if (icon.isNull()) qDebug() << "null"; qDebug() << mime_types[0].iconName(); return icon.pixmap(16); }

Maybe this work for Linux, but for Windows I need registers. Sample C# application https://www.codeproject.com/Articles/29137/Get-Registered-File-Types-and-Their-Associated-Ico

for example:
Computer\HKEY_CLASSES_ROOT.mp3 has
OpenWithProgIds/WMP11.AssocFile.MP3

Computer\HKEY_CLASSES_ROOT\WMP11.AssocFile.MP3 has DefaultIcon = %SystemRoot%\system32\wmploc.dll,-732
wmploc.dll is resources and 732 index of icon?

Good to know, so my solution to store this in the last column and hide this one is the best solution for me.

It's good when it's more friendly :)

@IL
you can add a widget to an item. So just create a for example frame that contains your icon and add it to the list item.

QListWidget *list = new QListWidget(this); //... QFrame *custom = new QFrame; //add whatever you need to the frame QListWidgetItem *i = new QListWidgetItem; list->addItem(i); list->setWidgetItem(i,custom);

I used this for a list where each item needed several buttons to get for example detailed information about the item or delete the item from the list with one click

Please have some patience, this forum is community driven and not all users live in the same timezone as you.

The picture you are linking to doesn't show a hovered button but a checked button. You will have that visual effect if you set the checkable property of the action to corresponding to the button as true and you check it.

@maximo
Agree.
I wonder if there is something secret I missed in some Doc.

Something like:

QIcon icon = style()->standardIcon(QStyle::SP_DialogOkButton); QPixmap pixmap = icon.pixmap(QSize(64, 64));

@marlenet15 See the docs : http://doc.qt.io/qt-5/qabstractbutton.html#iconSize-prop

What is the stack trace when this happens ?
