Channel scanner backend.
| ChannelScanner ( QObject *parent=0, const char *name=0 )
| ChannelScanner |
| ~ChannelScanner ()
| ~ChannelScanner |
[virtual]
| void setDevice ( V4LDev *device )
| setDevice |
| V4LDev * device ()
| device |
[const]
| void setStore ( ChannelStore *store )
| setStore |
| ChannelStore * store ()
| store |
[const]
| bool loadRegionFile ( const QString &filename )
| loadRegionFile |
Loads an XML region definition using ChannelScannerRegion.
| Channel * channel ()
| channel |
[const]
Returns the last channel found (or 0 if we haven't found one).
| void scan ()
| scan |
[slot]
Scans the current device and stores any channels found in the current store. This slot only kicks of the scan, so it returns quickly, the actual scanning is done with timers so the GUI doesn't block.
| void started ()
| started |
[signal]
Emitted when we start scanning.
| void progress ( int )
| progress |
[signal]
Emitted when we make one percent of progress.
| void done ()
| done |
[signal]
Emitted when the scan is complete.
| void done ( bool success )
| done |
[signal]
Emitted when the scan is complete.
Parameters:
| success | true iff we found any channels. |
| void foundChannel ()
| foundChannel |
[signal]
Emitted whenever we find a channel.
| bool first ()
| first |
[protected]
Prepare for a scan. Returns true if we're set to go.
| bool next ()
| next |
[protected]
Advance the scan by one. Returns true if we can continue, and false if we hit the end of the range.
| bool last ()
| last |
[protected]
Tidy up after the full range has been scanned.
| bool scanCurrent ()
| scanCurrent |
[protected]
Scans the current frequency and returns true if a channel is found. Note that this relies on being inside the first(), next(), last() loop and can't just scan an arbitrary place.
| bool regionFirst ()
| regionFirst |
[protected]
Initialise the frequency according to the region settings.
| bool regionNext ()
| regionNext |
[protected]
Advance the frequency according to the region settings.
| void addChannel ()
| addChannel |
[protected slots slot]
Adds the current frequency as a channel.
| void scanChunk ()
| scanChunk |
[protected slots slot]
Scans a chunk of the frequency range, then schedulers a timer to call itself to process the next chunk.
