Member Function Documentation

[explicit] QDesignerFormWindowInterface::QDesignerFormWindowInterface(QWidget *parent = nullptr, Qt::WindowFlags flags = {})

Constructs a form window interface with the given parent and the specified window flags.

[virtual noexcept] QDesignerFormWindowInterface::~QDesignerFormWindowInterface()

Destroys the form window interface.

[signal] void QDesignerFormWindowInterface::aboutToUnmanageWidget(QWidget *widget)

This signal is emitted whenever a widget on the form is about to become unmanaged. When this signal is emitted, the specified widget is still managed, and a widgetUnmanaged() signal will follow, indicating when it is no longer managed.

See also unmanageWidget() and isManaged().

[pure virtual] QDir QDesignerFormWindowInterface::absoluteDir() const

Returns the absolute location of the directory containing the form shown in the form window.

[slot] void QDesignerFormWindowInterface::activateResourceFilePaths(const QStringList &paths, int *errorCount = nullptr, QString *errorMessages = nullptr)

Activates the resource (.qrc) file paths paths, returning the count of errors in errorCount and error message in errorMessages. Qt Widgets Designer loads the resources using the QResource class, making them available for form editing.

In IDE integrations, a list of the project's resource (.qrc) file can be activated, making them available to Qt Widgets Designer.
