- Seeing as how there's some renewed interest in GTB, I thought I'd share my
- bug list with you all. And if Steen Raboel (who's email address I've lost)
- is reading this, perhaps you could forward this bug report to GTB's author
- on FIDOnet.
-
- Feel free to add to the list. Note these bugs are in GadToolsBox v1.3
- 37.111 (18.4.92) [available on FF659]...and not in gadtools.library.
- These bugs are in addition to those mentioned in Jan's TODO list.

-
- BUGS (some which are more or less the same)
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Button.c:
- * Can't turn off Disabled or Toggle options for button gadget
- if gadget has a user defined label
-
- Checkbox.c:
- * Can't turn off Disabled or Checked options for checkbox gadget
- if gadget has a user defined label
-
- * Can't turn off highlit gadget text
-
- Cycle.c:
- * Ignores Disabled option for cycle gadget (new for V37)
-
- * Can't turn off highlight gadget text
-
- ListView.c:
- * Can't turn off Read Only or Show Selected options for ListView
- gadget
-
- * Can't turn off highlit gadget text
-
- Mx.c:
- * If you delete all the labels previously entered, you're
- prevented from adding new ones; you get the error message
- "You already have the maximum number of labels entered !"
-
- Palette.c:
- * Can't turn off Disabled option for palette gadget
-
- * Can't turn off highlit gadget text
-
- Scroller.c & Slider.c:
- * Can't turn off Disabled option for scroller/slider gadgets
-
- * Can't turn on RelVerify option for scroller/slider gadget
-
- * Can't turn off highlit gadget text
-
- StrInt.c.c:
- * Can't turn off Disabled option for string or integer gadgets
-
- * Can't turn off highlit gadget text
-
- WindowSpecial.c:
- * Can't turn off ZOOM option in Edit Tags window; workaround
- is to turn off sizing gadget first (press F10)
- [reported by: d9mats@dtek.chalmers.se]
-
- Gen.c:
- * Fails to write WA_IDCMP flags for gadgets; last two args
- to setmem() transposed on line 211. See WriteGadToolsBoxIDCMP().
-
-
- FIXES
- ~~~~~
- The highlighting bug can be fixed in the Edit[GadgetType]() functions,
- by resetting the variable 'flag' to 0 before the IDCMP loop.
-
- The other "can't turn off/on" bugs can probably be fixed in the
- Change[GadgetType]() functions by removing the OR symbol in the code
- that reads:
-
- < if ( strncmp( slab, "Gadget", 6 ) && strlen( slab )) {
- < strcpy( &eng->en_SourceLabel[0], slab );
- ! eng->en_SpecialFlags |= EGF_USERLABEL;
- < } else
- < eng->en_SpecialFlags = 0l;
-
- to:
-
- > if ( strncmp( slab, "Gadget", 6 ) && strlen( slab )) {
- > strcpy( &eng->en_SourceLabel[0], slab );
- ! eng->en_SpecialFlags = EGF_USERLABEL;
- > } else
- > eng->en_SpecialFlags = 0l;
-
- In cases like StrInt.c, this is complicated by the unknown need by
- the author to preserve the special flags via a variable called 'spec'.
- Caution recommended when fixing these functions.
-
- The bug in Mx.c sounds similar to the one already fixed in Cycle.c.
-
- To fix the disabled ZOOM checkbox bug in WindowSpecial.c, the code
- should disable the checkbox when there is no sizing gadget, not when
- there is one.
-
- The bug in genc.c can be fixed by patching the executable (if you don't
- want to recompile the source). At about 73382 bytes offset from the
- beginning of the GadToolsBox [executable] file, change the hex bytes
- << 72 0E 70 00 >> to << 72 00 70 0E >>.
