Detailed Description

The QtGui module extends QtCore with GUI functionality.

To import the module use, for example, the following statement:

from PyQt4 import QtGui

Function Documentation

int qAlpha (int)

Returns the alpha component of the ARGB quadruplet rgba.

int qBlue (int)

Returns the blue component of the ARGB quadruplet rgb.

qDrawBorderPixmap (QPainter, QRect, QMargins, QPixmap)

qDrawPlainRect (QPainter, int, int, int, int, QColor, int lineWidth = 1, QBrush fill = None)

qDrawWinPanel (QPainter, int, int, int, int, QPalette, bool sunken = False, QBrush fill = None)

qDrawWinPanel (QPainter, QRect, QPalette, bool sunken = False, QBrush fill = None)

bool qFuzzyCompare (QMatrix, QMatrix)

bool qFuzzyCompare (QMatrix4x4, QMatrix4x4)

bool qFuzzyCompare (QTransform, QTransform)

bool qFuzzyCompare (QVector2D, QVector2D)

bool qFuzzyCompare (QVector3D, QVector3D)

bool qFuzzyCompare (QVector4D, QVector4D)

int qGray (int, int, int)

Returns a gray value (0 to 255) from the (r, g, b) triplet.

The gray value is calculated using the formula (r * 11 + g * 16 + b * 5)/32.

int qGray (int)

This is an overloaded function.

Returns a gray value (0 to 255) from the given ARGB quadruplet rgb.

The gray value is calculated using the formula (R * 11 + G * 16 + B * 5)/32; the alpha-channel is ignored.

qSwap (QKeySequence, QKeySequence)

qt_x11_wait_for_window_manager (QWidget widget)

Member Documentation

QApplication qApp

This member should be treated as a constant.

A global pointer referring to the unique application object. It is equivalent to the pointer returned by the QCoreApplication.instance() function except that, in GUI applications, it is a pointer to a QApplication instance.

Only one application object can be created.
