int QPaintDevice::numColors () const

Returns the number of different colors available for the paint device. Since this value is an int, it will not be sufficient to represent the number of colors on 32 bit displays, in this case INT_MAX is returned instead.

int QPaintDevice::x11AppCells ( int screen = -1 )   [static]

Use QX11Info::cells() instead.

For example, if you have code like

 int cells = QPaintDevice::x11AppCells(screen);

you can rewrite it as

 int cells = qApp->x11Info(screen).cells();

See also QWidget::x11Info() and QPixmap::x11Info().

Qt::HANDLE QPaintDevice::x11AppColormap ( int screen = -1 )   [static]

Use QX11Info::colormap() instead.

For example, if you have code like

 unsigned long colormap = QPaintDevice::x11AppColormap(screen);

you can rewrite it as

 unsigned long colormap = qApp->x11Info(screen).colormap();

See also QWidget::x11Info() and QPixmap::x11Info().

bool QPaintDevice::x11AppDefaultColormap ( int screen = -1 )   [static]

Use QX11Info::defaultColormap() instead.

For example, if you have code like

 bool isDefault = QPaintDevice::x11AppDefaultColormap(screen);

you can rewrite it as

 bool isDefault = qApp->x11Info(screen).defaultColormap();

See also QWidget::x11Info() and QPixmap::x11Info().

bool QPaintDevice::x11AppDefaultVisual ( int screen = -1 )   [static]

Use QX11Info::defaultVisual() instead.

For example, if you have code like

 bool isDefault = QPaintDevice::x11AppDefaultVisual(screen);

you can rewrite it as

 bool isDefault = qApp->x11Info(screen).defaultVisual();

See also QWidget::x11Info() and QPixmap::x11Info().

int QPaintDevice::x11AppDepth ( int screen = -1 )   [static]

Use QX11Info::depth() instead.

For example, if you have code like

 int depth = QPaintDevice::x11AppDepth(screen);

you can rewrite it as

 int depth = qApp->x11Info(screen).depth();

See also QWidget::x11Info() and QPixmap::x11Info().

Display * QPaintDevice::x11AppDisplay ()   [static]

Use QX11Info::display() instead.

you can rewrite it as

 Display *display = qApp->x11Info().display();

See also QWidget::x11Info() and QPixmap::x11Info().

int QPaintDevice::x11AppDpiX ( int screen = -1 )   [static]

Use QX11Info::appDpiX() instead.

For example, if you have code like

 bool isDefault = QPaintDevice::x11AppDpiX(screen);

you can rewrite it as

 bool isDefault = qApp->x11Info(screen).appDpiX();

See also QWidget::x11Info() and QPixmap::x11Info().

int QPaintDevice::x11AppDpiY ( int screen = -1 )   [static]

Use QX11Info::appDpiY() instead.

 bool isDefault = QPaintDevice::x11AppDpiY(screen);

you can rewrite it as

 bool isDefault = qApp->x11Info(screen).appDpiY();

See also QWidget::x11Info() and QPixmap::x11Info().

Qt::HANDLE QPaintDevice::x11AppRootWindow ( int screen = -1 )   [static]

Use QX11Info::appRootWindow() instead.

For example, if you have code like

 unsigned long window = QPaintDevice::x11AppRootWindow(screen);

you can rewrite it as

 unsigned long window = qApp->x11Info(screen).appRootWindow();
