- Parameters:
-
- Returns:
- true if it was added successfully, false if it wasn't.
| bool QStreamer::QPinList::contains |
( |
QPin * |
pin ) |
|
Returns true if the given pin exists in the list.
| bool QStreamer::QPinList::contains |
( |
const QString & |
name ) |
|
Returns true if a pin with the given name exists in the list.
| quint32 QStreamer::QPinList::count |
( |
) |
const |

| bool QStreamer::QPinList::remove |
( |
QPin * |
pin ) |
|
Removes the given pin from the list.
- Parameters:
-
| pin | the pin to attempt to remove. |
- Returns:
