1.1.1.3 root 8:
1.1 root 9: Use like this:
10: - Before screen surface is (re-)created Statusbar_SetHeight()
11: has to be called with the new screen height. Add the returned
12: value to screen height (zero means no statusbar). After this,
13: Statusbar_GetHeight() can be used to retrieve the statusbar size
14: - After screen surface is (re-)created, call Statusbar_Init()
15: to re-initialize / re-draw the statusbar
16: - Call Statusbar_SetFloppyLed() to set floppy drive led ON/OFF,
17: or call Statusbar_EnableHDLed() to enabled HD led for a while
1.1.1.9 root 18: - Whenever screen is redrawn, call Statusbar_Update() to update
19: statusbar contents and find out whether and what screen area
20: needs to be updated (outside of screen locking)
21: - If screen redraws can be partial, Statusbar_OverlayRestore()
1.1 root 22: needs to be called before locking the screen for drawing and
23: Statusbar_OverlayBackup() needs to be called after screen unlocking,
24: but before calling Statusbar_Update(). These are needed for
1.1.1.9 root 25: hiding the overlay drive led (= restoring the area that was below
26: them before LED was shown) when drive leds are turned OFF.
1.1 root 27: - If other information shown by Statusbar (TOS version etc) changes,
28: call Statusbar_UpdateInfo()
29:
30: TODO:
31: - re-calculate colors on each update to make sure they're
32: correct in Falcon & TT 8-bit palette modes?
33: - call Statusbar_AddMessage() from log.c?
