Member Function Documentation

bool ChannelScanner::loadRegionFile (  const QString & filename )

Loads an XML region definition using ChannelScannerRegion.

Channel* ChannelScanner::channel (  )  const [inline]

Returns the last channel found (or 0 if we haven't found one).

void ChannelScanner::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 ChannelScanner::started (  )  [signal]

Emitted when we start scanning.

void ChannelScanner::progress (  int )  [signal]

Emitted when we make one percent of progress.

void ChannelScanner::done (  )  [signal]

Emitted when the scan is complete.

void ChannelScanner::done (  bool success )  [signal]

Emitted when the scan is complete. Parameters: success   true iff we found any channels.

void ChannelScanner::foundChannel (  )  [signal]

Emitted whenever we find a channel.

bool ChannelScanner::first (  )  [protected]

Prepare for a scan. Returns true if we're set to go.

bool ChannelScanner::next (  )  [protected]

Advance the scan by one. Returns true if we can continue, and false if we hit the end of the range.

bool ChannelScanner::last (  )  [protected]

Tidy up after the full range has been scanned.

bool ChannelScanner::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 ChannelScanner::regionFirst (  )  [protected]

Initialise the frequency according to the region settings.

bool ChannelScanner::regionNext (  )  [protected]

Advance the frequency according to the region settings.

void ChannelScanner::addChannel (  )  [protected, slot]

Adds the current frequency as a channel.

void ChannelScanner::scanChunk (  )  [protected, slot]

Scans a chunk of the frequency range, then schedulers a timer to call itself to process the next chunk.
