PySide6.QtCore.QLibraryInfo

class QLibraryInfo

The QLibraryInfo class provides information about the Qt libraries.

Details

This class provides an abstraction for accessing information about the Qt libraries which the application is using, such as run-time paths, or the build configuration of the Qt libraries.

The default run-time paths depend on the Qt build configuration, as well as whether the Qt libraries have been relocated, and possibly bundled along with the application.

You can use a qt.conf file to override the default paths, in case your deployment situation does not match the defaults. For more information, see the Using qt.conf documentation.

Return type:

bool

Returns true if this is a shared (dynamic) build of Qt.

static location(location)

Parameters:

location – LibraryPath

Return type:

str

Note

This function is deprecated.

Use path() instead.

Returns the path specified by loc.
