Detailed Description

Function Documentation
QString QtMac::badgeLabelText()
Returns the text of the application icon a.k.a badge.
See also setBadgeLabelText().
CGContextRef QtMac::currentCGContext()
Returns the current CoreGraphics context.
QPixmap QtMac::fromCGImageRef(CGImageRef image)
Returns a QPixmap that is equivalent to the given image.
This function is not available in Qt 5.x until 5.0.2 and will return a null pixmap in earlier versions.
See also toCGImageRef() and Pixmap Conversion.
bool QtMac::isMainWindow(QWindow *window)
Returns whether the given QWindow window is the application's main window
void QtMac::setBadgeLabelText(const QString &text)
Sets the text shown on the application icon a.k.a badge.
This is generally used with numbers (e.g. number of unread emails); it can also show a string.
See also badgeLabelText().
CGImageRef QtMac::toCGImageRef(const QPixmap &pixmap)
Creates a CGImageRef equivalent to the QPixmap pixmap. Returns the CGImageRef handle.
It is the caller's responsibility to release the CGImageRef data after use.
This function is not available in Qt 5.x until 5.0.2 and will return NULL in earlier versions.
See also fromCGImageRef().
NSImage *QtMac::toNSImage(const QPixmap &pixmap)
Creates an NSImage equivalent to the QPixmap pixmap. Returns the NSImage handle.
It is the caller's responsibility to release the NSImage data after use.
