|
|---|
| 4 | * Purpose: This implements the MythKeySequence class. QKeySequence cannot
|
|---|
| 5 | * be easily extended not to ignore 'remoteXXX' identifiers.
|
|---|
| 6 | *
|
|---|
| 7 | * This replacement class fixes that and removes the need for
|
|---|
| 8 | * some duplicate code in MythTV and the MythControls-plugin.
|
|---|
| 9 | *
|
|---|
| 10 | * History:
|
|---|
| 11 | *
|
|---|
| 12 | * 20060620
|
|---|
| 13 | * - Renamed member routine 'keyNum()' to 'value()'.
|
|---|
| 14 | * - Bugfixed problem with 'F1,M,{,<' only assigning 3 keys.
|
|---|
| 15 | * - Max.length of sequence configurable through #define MYTHKEY_SEQLEN.
