NAME
AddAppIcon - add an icon to workbench's list of appicons. (V36)
SYNOPSIS
AppIcon = AddAppIconA(id, userdata, text, msgport,
D0 D0 D1 A0 A1
lock, diskobj, taglist)
A2 A3 A4
struct AppIcon *AddAppIconA(ULONG, ULONG, char *,
struct MsgPort *, struct FileLock *, struct DiskObject *,
struct TagItem *);
Alternate, varargs version:
struct AppIcon *AddAppIcon(ULONG, ULONG, char *,
struct MsgPort *, struct FileLock *,
struct DiskObject *,
tag1, data1,
tag2, data2,
...
TAG_END );
FUNCTION
Attempt to add an icon to workbench's list of appicons. If
successful, the icon is displayed on the workbench (the same
place disk icons are displayed).
This call is provided to allow applications to be notified when
a graphical object (non neccessarely associated with a file)
gets 'manipulated'. (explained later).
The notification consists of an AppMessage (found in workbench.h/i)
of type 'MTYPE_APPICON' arriving at the message port you specified.
The types of 'manipulation' that can occur are:
1. Double-clicking on the icon. am_NumArgs will be zero and
am_ArgList will be NULL.
2. Dropping an icon or icons on your appicon. am_NumArgs will
be the number of icons droppped on your app icon plus one.
am_ArgList will be an array of ptrs to WBArg structures.
Refer to the 'WBStartup Message' section of the RKM for more info.
3. Dropping your appicon on another icon. NOT SUPPORTED.
INPUTS
id - this variable is strictly for your own use and is ignored by
workbench. Typical uses in C are in switch and case statements,
and in assembly language table lookup.
userdata - this variable is strictly for your own use and is ignored
by workbench.
text - name of icon (char *)
lock - NULL (Currently unused)
msgport - pointer to message port workbench will use to send you an
AppMessage message of type 'MTYPE_APPICON' when your icon
gets 'manipulted' (explained above).
diskobj - pointer to a DiskObject structure filled in as follows:
do_Magic - NULL
do_Version - NULL
do_Gadget - a gadget structure filled in as follows:
NextGadget - NULL
LeftEdge - NULL
TopEdge - NULL
Width - width of icon hit-box
Height - height of icon hit-box
Flags - NULL or GADGHIMAGE
Activation - NULL
GadgetType - NULL
GadgetRender - pointer to Image structure filled in as follows:
LeftEdge - NULL
TopEdge - NULL
Width - width of image (must be <= Width of hit box)
Height - height of image (must be <= Height of hit box)
Depth - # of bit-planes in image
ImageData - pointer to actual word aligned bits (CHIP MEM)
PlanePick - Plane mask ((1 << depth) - 1)
PlaneOnOff - 0
NextImage - NULL
SelectRender - pointer to alternate Image struct or NULL
GadgetText - NULL
MutualExclude - NULL
SpecialInfo - NULL
GadgetID - NULL
UserData - NULL
do_Type - NULL
do_DefaultTool - NULL
do_ToolTypes - NULL
do_CurrentX - NO_ICON_POSITION (recommended)
do_CurrentY - NO_ICON_POSITION (recommended)
do_DrawerData - NULL
do_ToolWindow - NULL
do_StackSize - NULL
(an easy way to create one of these (a DiskObject) is to create an icon
with the V2.0 icon editor and save it out. Your application can then
call GetDiskObject on it and pass that to AddAppIcon.)
taglist - ptr to a list of tag items. Must be NULL for V2.0.
RESULTS
AppIcon - a pointer to an appicon structure which you pass to
RemoveAppIcon when you want to remove the icon
from workbench's list of appicons. NULL
if workbench was unable to add your icon; typically
happens when workbench is not running or under low
memory conditions.
EXAMPLE
You could design a print-spooler icon and add it to the workbench.
Any file dropped on the print spooler would be printed. If the
user double-clicked (opended) your printer-spooler icon, you could
open a window showing the status of the print spool, allow changes
to print priorities, allow deletions, etc. If you registered this
window as an 'appwindow' (explained in workbench.library AddAppWindow)
files could also be dropped in the window and added to the spool.

BUGS
Currently Info cannot be obtained on appicons.
workbench.library/AddAppMenuItemA workbench.library/AddAppMenuItemA
NAME
AddAppMenuItem - add a menuitem to workbench's list (V36)
of appmenuitems.
SYNOPSIS
AppMenuItem = AddAppMenuItemA(id, userdata, text, msgport, taglist)
D0 D0 D1 A0 A1 A2
struct AppMenuItem *AddAppMenuItemA(ULONG, ULONG, char *,
struct MsgPort *,
struct TagItem *);
Alternate, varargs version:
struct AppMenuItem *AddAppMenuItem(ULONG, ULONG, char *,
struct MsgPort *,
tag1, data1,
tag2, data2,
...
TAG_END );
FUNCTION
Attempt to add the text as a menuitem to workbench's list
of appmenuitems (the 'Tools' menu strip).
INPUTS
id - this variable is strictly for your own use and is ignored by
workbench. Typical uses in C are in switch and case statements,
and in assembly language table lookup.
userdata - this variable is strictly for your own use and is ignored
by workbench.
text - text for the menuitem (char *)
msgport - pointer to message port workbench will use to send you an
AppMessage message of type 'MTYPE_APPMENUITEM' when your
menuitem gets selected.
taglist - ptr to a list of tag items. Must be NULL for V2.0.
RESULTS
AppMenuItem - a pointer to an appmenuitem structure which you pass to
RemoveAppMenuItem when you want to remove the menuitem
from workbench's list of appmenuitems. NULL if
workbench was unable to add your menuitem; typically
happens when workbench is not running or under low
memory conditions.
SEE ALSO
RemoveAppMenuItem()
BUGS
Currently does not limit the system to 63 menu items...
Any menu items after the 63rd will not be selectable.
workbench.library/AddAppWindowA workbench.library/AddAppWindowA
NAME
AddAppWindow - add a window to workbench's list of appwindows. (V36)
SYNOPSIS
AppWindow = AddAppWindowA(id, userdata, window, msgport, taglist)
D0 D0 D1 A0 A1 A2
struct AppWindow *AddAppWindowA(ULONG, ULONG, struct Window *,
struct MsgPort *, struct TagItem *);
Alternate, varargs version:
struct AppWindow *AddAppWindow(ULONG, ULONG, struct Window *,
struct MsgPort *
tag1, data1,
tag2, data2,
...
TAG_END );
FUNCTION
Attempt to add the window to workbench's list of appwindows.
Normally non-workbench windows (those not opened by workbench)
cannot have icons dropped in them. This call is provided to
allow applications to be notified when an icon or icons get
dropped inside a window that they have registered with workbench.
The notification consists of an AppMessage (found in workbench.h/i)
of type 'MTYPE_APPWINDOW' arriving at the message port you specified.
What you do with the list of icons (pointed to by am_ArgList) is
up to you, but generally you would want to call GetDiskObjectNew on
them.
INPUTS
id - this variable is strictly for your own use and is ignored by
workbench. Typical uses in C are in switch and case statements,
and in assembly language table lookup.
userdata - this variable is strictly for your own use and is ignored
by workbench.
window - pointer to window to add.
msgport - pointer to message port workbench will use to send you an
AppMessage message of type 'MTYPE_APPWINDOW' when your
window gets an icon or icons dropped in it.
taglist - ptr to a list of tag items. Must be NULL for V2.0.
RESULTS
AppWindow - a pointer to an appwindow structure which you pass to
RemoveAppWindow when you want to remove the window
from workbench's list of appwindows. NULL
if workbench was unable to add your window; typically
happens when workbench is not running or under low
memory conditions.
SEE ALSO
RemoveAppWindow()
NOTES
The V2.0 icon editor is an example of an app window. Note that app
window applications generally want to call GetDiskObjectNew
(as opposed to GetDiskObject) to get the disk object for the icon
dropped in the window.
