Detailed Description

\inmodule QtCore

QFileSelector provides a convenient way of selecting file variants.

Since
5.2

QFileSelector is a convenience for selecting file variants based on platform or device characteristics. This allows you to develop and deploy one codebase containing all the different variants more easily in some circumstances, such as when the correct variant cannot be determined during the deploy step.

Constructor & Destructor Documentation

◆ QFileSelector()

QFileSelector::QFileSelector ( QObject * parent = nullptr)
explicit

Create a QFileSelector instance.

This instance will have the same static selectors as other QFileSelector instances, but its own set of extra selectors.

If supplied, it will have the given QObject parent.

Definition at line 136 of file qfileselector.cpp.

◆ ~QFileSelector()

QFileSelector::~QFileSelector ( )

Destroys this selector instance.

Definition at line 144 of file qfileselector.cpp.

Member Function Documentation

◆ allSelectors()

QStringList QFileSelector::allSelectors ( ) const

Returns the complete, ordered list of selectors used by this instance.

◆ extraSelectors()

QStringList QFileSelector::extraSelectors ( ) const

Returns the list of extra selectors which have been added programmatically to this instance.

References d.

◆ select() [1/2]

QString QFileSelector::select ( const QString & filePath) const

This function returns the selected version of the path, based on the conditions at runtime.

If no selectable files are present, returns the original filePath.

If the original file does not exist, the original filePath is returned. This means that you must have a base file to fall back on, you cannot have only files in selectable sub-directories.

See the class overview for the selection algorithm.

◆ select() [2/2]

QUrl QFileSelector::select ( const QUrl & filePath) const

This is a convenience version of select operating on QUrl objects.

If the scheme is not file or qrc, filePath is returned immediately. Otherwise selection is applied to the path of filePath and a QUrl is returned with the selected path and other QUrl parts the same as filePath.

See the class overview for the selection algorithm.

◆ setExtraSelectors()

void QFileSelector::setExtraSelectors ( const QStringList & list)

Sets the list of extra selectors which have been added programmatically to this instance.

These selectors have priority over any which have been automatically picked up.
