QString QtMac:: badgeLabelText ()

Returns the text of the application icon a.k.a badge.

CGContextRef QtMac:: currentCGContext ()

Returns the current CoreGraphics context.

QPixmap QtMac:: fromCGImageRef ( CGImageRef image )

返回 QPixmap 相当于给定 image .

This function is not available in Qt 5.x until 5.0.2 and will return a null pixmap in earlier versions.

另请参阅 toCGImageRef () 和 像素图转换 .

bool QtMac:: isMainWindow ( QWindow * window )

Returns whether the given QWindow window is the application's main window

void QtMac:: setBadgeLabelText (const QString & text )

设置 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.

另请参阅 badgeLabelText ().

CGImageRef QtMac:: toCGImageRef (const QPixmap & pixmap )

创建 CGImageRef equivalent to the QPixmap pixmap 。返回 CGImageRef 句柄。

It is the caller's responsibility to release the CGImageRef 数据在使用后。

This function is not available in Qt 5.x until 5.0.2 and will return NULL in earlier versions.
