## Member Function Documentation

### QPalette::QPalette(const QColor &windowText, const QColor &window, const QColor &light, const QColor &dark, const QColor &mid, const QColor &text, const QColor &base)

This function is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code.

Constructs a palette with the specified windowText, window, light, dark, mid, text, and base colors. The button color will be set to the window color.

### const QBrush &QPalette::background() const

This function is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code.

Use window() instead.

### const QBrush &QPalette::foreground() const

This function is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code.

Use windowText() instead.

### int QPalette::serialNumber() const

This function is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code.

Returns a number that identifies the contents of this QPalette object. Distinct QPalette objects can only have the same serial number if they refer to the same contents (but they don't have to). Also, the serial number of a QPalette may change during the lifetime of the object.

Use cacheKey() instead.

Warning: The serial number doesn't necessarily change when the palette is altered. This means that it may be dangerous to use it as a cache key.
