详细描述

The QtCore module contains non-GUI functionality.

All other PyQt modules rely on this module. To import the module use, for example, the following statement:

from PyQt4 import QtCore

QTextStream bin ( QTextStream   s )

QTextStream bin_ ( QTextStream   s )

QTextStream bom ( QTextStream   s )

QTextStream center ( QTextStream   s )

QTextStream dec ( QTextStream   s )

QTextStream endl ( QTextStream   s )

QTextStream fixed ( QTextStream   s )

QTextStream flush ( QTextStream   s )

Flushes any buffered data waiting to be written to the 设备。

若 QTextStream operates on a string, this function does nothing.

QTextStream forcepoint ( QTextStream   s )

QTextStream forcesign ( QTextStream   s )

QTextStream hex ( QTextStream   s )

QTextStream hex_ ( QTextStream   s )

QTextStream left ( QTextStream   s )

QTextStream lowercasebase ( QTextStream   s )

QTextStream lowercasedigits ( QTextStream   s )

QTextStream noforcepoint ( QTextStream   s )

QTextStream noforcesign ( QTextStream   s )

QTextStream noshowbase ( QTextStream   s )

QTextStream oct ( QTextStream   s )

QTextStream oct_ ( QTextStream   s )

int-or-None pyqtPickleProtocol ()

pyqtRemoveInputHook ()

When the QtCore module is imported for the first time it installs a Python input hook (ie. it sets the value of Python's PyOS_InputHook variable). This allows commands to be entered at the interpreter prompt while the application is running. It is then possible to dynamically create new Qt objects and call the methods of any existing Qt object.

The input hook can cause problems for certain types of application, particularly those that provide a similar facility through different means. This function removes the input hook installed by PyQt.

The input hook can be restored using the pyqtRestoreInputHook() 函数。

pyqtRestoreInputHook ()

When the QtCore module is imported for the first time it installs a Python input hook (ie. it sets the value of Python's PyOS_InputHook variable). This allows commands to be entered at the interpreter prompt while the application is running. It is then possible to dynamically create new Qt objects and call the methods of any existing Qt object.

The input hook can cause problems for certain types of application, particularly those that provide a similar facility through different means, and so the pyqtRemoveInputHook() function is provided to remove it.

This function will restore the input hook if it has been removed.
