My app has a screen that requires the user to write their signature on the screen. I've
found out that if the user has the "Write Anywhere" feature enabled on their
Palm, it causes strange behavior on the signature entry screen that prevents the
signature from being recorded.
The "Write Anywhere" feature is enabled by going into Prefs->General->Writing
Area.
Does anyone know of a way to enable/disable this feature programatically? I've
gone through the 68k documentation and I can't seem to find anything related to
this.
UInt16 gGoLCDLibRefNum = None;
if ( SysLibFind( goLcdLibName, &gGoLCDLibRefNum ) != errNone )
if ( SysLibLoad( goLcdLibType, goLcdLibCreator, &gGoLCDLibRefNum ) ==
errNone )
if ( GoLcdLibOpen( gGoLCDLibRefNum ) == errNone )
if ( GoLcdGetStatus( gGoLCDLibRefNum ) == goLcdEnabled )
GoLcdSetStatus( gGoLCDLibRefNum, goLcdDisabled );
Conversely, you should call this last API again upon exiting to restore
the previous status if need be (I keep a static boolean to determine
whether I must do that upon closing the forms where I want "Graffiti On
LCD" writing disabled). And close and remove the library when exiting
your app. Check Palm's GoLCD Guide (PDF).
Caveat: the GoLcdSetStatus API does not change the icon in the status
bar at the bottom of the Palm screen (like on the T3). I have no idea
how to do that :(
