* TODO:
|
||||
* - handle dragging slider better
|
||||
* - increase with of the paging area
|
||||
* - implement autorepeat for paging
|
||||
* - possition buddy controls
|
||||
* - better tic handling.
|
||||
* - more notifications.
|
||||
* - TBM_SETRANGEMAX & TBM_SETRANGEMIN should only change the view of the
|
||||
* trackbar, not the actual amount of tics in the list.
|
||||
* - TBM_GETTIC & TBM_GETTICPOS shouldn't rely on infoPtr->tics being sorted.
|
||||
* - custom draw notifications
|
||||
* - implement TBS_DOWNISLEFT
|
||||
* - fix tics drawing for TBS_BOTH
|
||||
* - use fLocation (TBTS_{TOP,LEFT,BUTTOM,RIGHT})
