gadgetclass
bevel.image
This gadget is a special form of a strggclass gadget for entering
positive or negative long integers. The user can type in the number
or use the arrows to adjust the number up or down.
Advantages that this class provides:
> Supports window relativity.
> Optionally creates arrows for adjusting the value.
> Definable minimum and maximum values as well as maximum number
of characters.
> Supports OS 3.0 BOOPSI Gadget HelpTest.
OM_NEW -- Create the integer gadget. Passed to superclass.
OM_SET -- Set object attributes. Passed to superclass first.
OM_DISPOSE -- Cancels the integer menu before being passed onto
superclass.
OM_UPDATE -- Set object notification attributes. Passed to superclass
first.
GM_RENDER -- Renders the gadget imagry. Overrides the superclass.
GM_GOACTIVE -- Handles activation, pops up the integer menu. Overrides
the superclass.
GM_HANDLEINPUT -- Handles input events once active. Overrides the
superclass.
GM_GOINACTIVE -- Closes the integer menu. Overrides the superclass.
All other methods are passed to the superclass.
GA_Disabled (BOOL)
Set to TRUE to disable gadget, FALSE otherwise
Defaults to FALSE.
Applicability is (OM_NEW, OM_SET, OM_GET)
GA_TextAttr (struct TextAttr *)
Font to use for the gadget text.
Defaults to the screen's font.
Applicability is (OM_NEW, OM_SET, OM_GET)
INTEGER_Number (LONG)
The value for the integer gadget. The class will adjust this
number to fit into the range you define. The current value for
INTEGER_Number will be returned in IntuiMessage.Code on
IDCMP_GADGETUP as a WORD. Note that since the gadget handles
values of size LONG, the value returned in IntuiMessage.Code
will only be valid if the ranges you are allowing fit into a
WORD value. Otherwise you will have to use GetAttr().
Defaults to 0.
Applicability is (OM_NEW, OM_SET, OM_GET, OM_NOTIFY)
INTEGER_MaxChars (WORD)
Maximum number of characters you are allowing the number to be.
This is including an optional negative sign (-).
Defaults to 10.
Applicability is (OM_NEW, OM_SET, OM_GET, OM_NOTIFY)
INTEGER_Minimum (LONG)
Minimum value the number can have.
Applicability is (OM_NEW, OM_SET, OM_GET, OM_NOTIFY)
INTEGER_Maximum (LONG)
Maximum value the number can have.
Applicability is (OM_NEW, OM_SET, OM_GET, OM_NOTIFY)
INTEGER_Arrows (BOOL)
Should arrows be displayed for adjusting the number? The class
is smart enough to not render arrows if the gadget becomes too
small.
Defaults to TRUE.
Applicability is (OM_NEW, OM_SET, OM_GET)
INTEGER_MinVisible (UWORD)
If set, this tag specifies the minimum number of numeric
characters which should be visible at the gadgets minimum
domain size. This tag effects GM_DOMAIN's result to tweak
the display in a pleasing way.
Defaults to 0.
Applicability is (OM_NEW, OM_SET)
All strggclass tags can be used with OM_NEW, OM_SET and OM_GET
except for STRINGA_LongVal and STRINGA_MaxChars. Use INTEGER_Number
and INTEGER_MaxChars instead.
