AddAppIconA()

Synopsis

struct AppIcon * AddAppIconA(
         IPTR id,
         IPTR userdata,
         const char * text,
         struct MsgPort * msgport,
         BPTR lock,
         struct DiskObject * diskobj,
         struct TagItem * taglist );

struct AppIcon * AddAppIcon(
         IPTR id,
         IPTR userdata,
         const char * text,
         struct MsgPort * msgport,
         BPTR lock,
         struct DiskObject * diskobj,
         TAG tag, ... );

Function

Add an icon to the workbench's list of AppIcons. If a workbench is
running, the icon will appear on the workbench screen given that the
call is successful.
    When a user interacts with the AppIcon, an AppMessage of type
MTYPE_APPICON is sent to the message port specified. The different
supported actions are:

1. User double-clicking on the icon. am_NumArgs is zero and am_ArgList is
   NULL.
2. Dropping one or more icons on the AppIcon. am_Numargs is the number of
   icons dropped plus one; am_ArgList is an array of pointers to WBArg
   structures of the icons dropped.
3. Dropping the AppIcon on another icon -- NOT SUPPORTED.
4. Invoking an "Icons" menu item when the AppIcon is selected. am_Class
   will be set to a value in AMCLASSICON_Open ... AMCLASSICON_EmptyTrash.

Tags

WBAPPICONA_SupportsOpen (BOOL)
Set to TRUE if the AppIcon should respond to the "Open" menu.
[default = TRUE]

WBAPPICONA_SupportsCopy (BOOL)
Set to TRUE if the AppIcon should respond to the "Copy" menu.
[default = FALSE]

WBAPPICONA_SupportsRename (BOOL)
Set to TRUE if the AppIcon should respond to the "Rename" menu.
[default = FALSE]

WBAPPICONA_SupportsInformation (BOOL)
Set to TRUE if the AppIcon should respond to the "Information" menu.
[default = FALSE]

WBAPPICONA_SupportsSnapshot (BOOL)
Set to TRUE if the AppIcon should respond to the "Snapshot" menu.
[default = FALSE]

WBAPPICONA_SupportsUnSnapshot (BOOL)
Set to TRUE if the AppIcon should respond to the "UnSnapshot" menu.
[default = FALSE]

WBAPPICONA_SupportsLeaveOut (BOOL)
Set to TRUE if the AppIcon should respond to the "Leave Out" menu.
[default = FALSE]

WBAPPICONA_SupportsPutAway (BOOL)
Set to TRUE if the AppIcon should respond to the "Put Away" menu.
[default = FALSE]

WBAPPICONA_SupportsDelete (BOOL)
Set to TRUE if the AppIcon should respond to the "Delete" menu.
[default = FALSE]

WBAPPICONA_SupportsFormatDisk (BOOL)
Set to TRUE if the AppIcon should respond to the "Format Disk" menu.
[default = FALSE]

WBAPPICONA_SupportsEmptyTrash (BOOL)
Set to TRUE if the AppIcon should respond to the "Empty Trash" menu.
[default = FALSE]

WBAPPICONA_PropagatePosition (BOOL)
Set to TRUE if the AppIcon's position should be updated in the DiskObject
passed to this function when the AppIcon is moved. If this is set to TRUE,
workbench.library will assume that the structure is not freed as long as
the AppIcon is alive.
[default = FALSE]

WBAPPICONA_RenderHook (struct Hook *)
Pointer to a hook that will be invoked when the AppIcon is rendered.
Using this hook and WorkbenchControlA() dynamic or animated AppIcons may
be created. The hook will be called with the following parameters:

      result = hookFunc(hook, reserved, arm);

      where the 'hookFunc' has the prototype

      LONG hookFunc(struct Hook *hook, APTR reserved,
                    struct AppIconRenderMsg *arm);

If the hook function returns TRUE, the regular image of the AppIcon will
be drawn; if it returns FALSE, nothing will be drawn. This allows you to
do all the icon rendering except for when dragging the icon on the screen.

WBAPPICONA_NotifySelectState (BOOL)
When TRUE, you will be notificed whenever the AppIcon becomes selected or
unselected; the am_Class will be set to AMCLASSICON_Selected or
AMCLASSICON_Unselected.

Result

A pointer to an AppIcon structure -- which should be used with
RemoveAppIcon() when you want to remove the icon -- or NULL if it was
not possible to add the AppIcon.

Notes

Contrary to AmigaOS, AppIcons may be added when there is no workbench
application running.

AddAppMenuItemA()

Synopsis

struct AppMenuItem * AddAppMenuItemA(
         IPTR id,
         IPTR userdata,
         APTR text,
         struct MsgPort * msgport,
         struct TagItem * taglist );

struct AppMenuItem * AddAppMenuItem(
         IPTR id,
         IPTR userdata,
         APTR text,
         struct MsgPort * msgport,
         TAG tag, ... );

Function

Try to add a menu item to workbench.library's list of AppMenuItems (this
will be shown in the 'Tools' menu strip in Workbench).

Inputs

id        --  menu item identifier; for your convenience (ignored by
              workbench.library)
userdata  --  user specific data (ignored by workbench.library)
text      --  menu item text; any text consisting merely of '-','_' and
              '~' characters corresponds to a separator bar instead of
              a textual item
msgport   --  port to which notification messages regarding the menu
              item will be sent
taglist   --  tags (see below)

Tags

WBAPPMENUA_CommandKeyString (STRPTR)
Command key assigned to this menu item. If the string is empty, it will
be ignored as will it if the command key is already in use by another
menu item. Only the first character of the string will be used.
[default = NULL]

Result

A pointer to an AppMenuItem which you pass to RemoveAppMenuItem() when
you want to remove the menu item. If it was not possible to add the menu
item, NULL will be returned.

Notes

Contrary to AmigaOS, this function will report success even when there
is no running workbench application.

AddAppWindowA()

Synopsis

struct AppWindow * AddAppWindowA(
         IPTR id,
         IPTR userdata,
         struct Window * window,
         struct MsgPort * msgport,
         struct TagItem * taglist );

struct AppWindow * AddAppWindow(
         IPTR id,
         IPTR userdata,
         struct Window * window,
         struct MsgPort * msgport,
         TAG tag, ... );

Function

Try to add an AppWindow to workbench.library's list of AppWindows.
The supplied message port will be used to send notification messages
whenever an icon is dropped on the window. The message will be of
type 'AMTYPE_APPWINDOW' and am_ArgList will point to the list of icons
that were dropped in the window.

Inputs

id        --  window identifier; for your convenience (ignored by
              workbench.library)
userdata  --  user specific data (ignored by workbench.library)
window    --  pointer to the window to add AppWindow functionality to
msgport   --  port to which notification messages regarding the window
              will be sent
taglist   --  tags (must be NULL)

Result

A pointer to an AppWindow structure to use with RemoveAppWindow() when
you want to remove the window from the list of AppWindows, or NULL
if it was not possible to add the window to the AppWindow list.

Notes

Applications generally want to call GetDiskObjectNew() -- rather than
GetDiskObject() -- to get disk objects for icons dropped in the window.
    Contrary to AmigaOS, this function will succeed even when there
is no running workbench application.

AddAppWindowDropZoneA()

Synopsis

struct AppWindowDropZone * AddAppWindowDropZoneA(
         struct AppWindow * aw,
         IPTR id,
         IPTR userdata,
         struct TagItem * tags );

struct AppWindowDropZone * AddAppWindowDropZone(
         struct AppWindow * aw,
         IPTR id,
         IPTR userdata,
         TAG tag, ... );

Function

A regular AppWindow, when created with AddAppWindowA() will respond to
dropping icons anywhere in the window. With this function you can specify
which parts of the window are suitable for dropping icons on.

Inputs

aw        --  An AppWindow structure as returned by AddAppWindowA()
id        --  drop zone identifier; for your convenience (ignored by
              workbench.library)
taglist   --  tags (see below)

Tags

WBDZA_Left (WORD)
Left edge of the drop zone relative to the left window edge.

WBDZA_RelRight (WORD)
Left edge of the drop zone relative to the right window edge. A value
of -20 would create a zone located 20 pixels to the left of the right
window edge.

WBDZA_Top (WORD)
Top edge of the drop zone relative to the top of the window.

WBDZA_RelBottom (WORD)
Top edge of the drop zone relative to the window height; a value of -20
would create a zone located 20 pixels above the window bottom edge.

WBDZA_Width (WORD)
Widthof the drop zone in pixels.

WBDZA_RelWidth (WORD)
Width of the drop zone relative to the width of the window; a value of
-20 would create a zone that is 20 pixels narrower than the window.

WBDZA_Height (WORD)
Height of the drop zone in pixels.

WBDZA_RelHeight
Height of the drop zone relative to the height of the window; a value of
-20 would create a zone that is 20 pixels smaller than the window.

WBDZA_Box (struct IBox *)
Position and size of the drop zone

WBDZA_Hook (struct Hook *)
Pointer to a hook that will be called whenever the mouse enters or leaves
your drop zone. The hook will be called with the following parameters.

     hookFunc(hook, reserved, arm);

where the 'hookFunc' is prototyped as:

     LONG hookFunc(struct Hook *hook, APTR reserved,
                   struct AppWindowDropZoneMsg *adzm);

Your hook function should always return 0. You must limit the rendering
done in the 'hookFunc' to simple graphics.library operations as otherwise
you risk deadlocking the system.

Result

A drop zone identifier or NULL if the drop zone could not be created.

Notes

When a drop zone is installed, the messages received when icons are
dropped are of type 'AMTYPE_APPWINDOWZONE' instead of 'AMTYPE_APPWINDOW'.
    You must be able to handle both types of messages if you call this
function.
    Drop zones must be created with a position and a size; otherwise this
function will fail.
    When an icon is dropped on a drop zone, the AppMessage am_MouseX and
am_MouseY members will be relative to the window top left corner and NOT
relative to the drop zone coordinates.

ChangeWorkbenchSelectionA()

Synopsis

BOOL ChangeWorkbenchSelectionA(
         STRPTR name,
         struct Hook * hook,
         struct TagItem * tags );

BOOL ChangeWorkbenchSelection(
         STRPTR name,
         struct Hook * hook,
         TAG tag, ... );

CloseWorkbenchObjectA()

Synopsis

BOOL CloseWorkbenchObjectA(
         STRPTR name,
         struct TagItem * tags );

BOOL CloseWorkbenchObject(
         STRPTR name,
         TAG tag, ... );

GetNextAppIcon()

Synopsis

struct DiskObject * GetNextAppIcon(
         struct DiskObject * lastdiskobj,
         char * text );

Function

Accesses AppIcon information from workbench.library. This function
is meant for iterations through wblibs´ AppIcon storage as needed
to display those.
    Initialised with a NULL as the first argument, it iterates
through all AppIcons stored in workbench.library by returning the
pointer to the next AppIcon´s DiskObject structure and copies the
name of the given AppIcon to the given array. The function returns
a NULL if the end of AppIcon list was reached or if no AppIcons
were stored.

Inputs

lastdiskobj  --  NULL (initial value) or pointer to a DiskObject
                 structure stored in workbench.library
text         --  char array pointer to store AppIcon´s name in

Result

A pointer to an DiskObject structure -- which should be used within
the next function call to access the next AppIcon -- or NULL if no
AppIcons were found or end of list was reached.

Example

struct DiskObject *_nb_dob = NULL;
char text[32];

while ( _nb_dob = GetNextAppIcon(_nb_dob, &text) )
{
    printf("appicon found: %s \n", text);
}

MakeWorkbenchObjectVisibleA()

Synopsis

BOOL MakeWorkbenchObjectVisibleA(
         STRPTR name,
         struct TagItem * tags );

BOOL MakeWorkbenchObjectVisible(
         STRPTR name,
         TAG tag, ... );

OpenWorkbenchObjectA()

Synopsis

BOOL OpenWorkbenchObjectA(
         STRPTR name,
         struct TagItem * tags );

BOOL OpenWorkbenchObject(
         STRPTR name,
         TAG tag, ... );

QuoteWorkbench()

Synopsis

BOOL QuoteWorkbench(
         ULONG stringNum );

RegisterWorkbench()

Synopsis

BOOL RegisterWorkbench(
         struct MsgPort * messageport );

Function

The workbench application uses this function to register itself with
the library. When it has done this, the library sends messages to the
specified port about actions the application is supposed to carry out.

All messages sent to the message port are of struct WBHandlerMessage,
which is specified in <workbench/handler.h>. The wbhm_Type field
identifies the type of message and which part of the wbhm_Data union
is relevant. The following types are currently defined:

WBHM_TYPE_SHOW
    Intuition has (re)opened the Workbench Screen, and request that
    you open all your windows. When the message is replied, Intuition
    assumes that the windows have been opened.

WBHM_TYPE_HIDE
    Intuition is about to close the Workbench Screen, and request that
    you close all your windows. When the message is replied, Intuition
    assumes that the windows have been closed and will try to close the
    screen.

WBHM_TYPE_OPEN
    Request to open the specified drawer.

WBHM_TYPE_UPDATE
    The state of the specified disk object has changed, and this
    message serves as a notification and suggestion that you should
    update its visual representation to the user. For example, it
    might have been deleted or renamed.

Inputs

messageport - The message port to send the to.

Result

TRUE if the message port was successfully registered, FALSE otherwise.
The registration will fail if an other message port has already been
registered earlier or if a NULL pointer was passed in.

Notes

As you can read above, only one workbench application can be registered
at a time. This is intentional. Note that "workbench application" in
this context means the program that is the file manager and handles
the GUI, not a program that is started using OpenWorkbenchObjectA()!

RemoveAppIcon()

Synopsis

BOOL RemoveAppIcon(
         struct AppIcon * appIcon );

Function

Try to remove an AppIcon from workbench.library's list of AppIcons.

Inputs

appIcon  --  pointer to an AppIcon got from AddAppIconA()

Result

TRUE if the icon could be removed, FALSE otherwise.

Notes

You must do a final check for messages on your AppMessage port as messages
may have been sent between the last time you checked and the call to
this function.

RemoveAppMenuItem()

Synopsis

BOOL RemoveAppMenuItem(
         struct AppMenuItem * appMenuItem );

Function

Try to remove an AppMenuItem from workbench.library's list of AppMenuItems.

Inputs

Pointer to an AppMenuItem structure as returned by AddAppMenuItem().

Result

TRUE if the menu item could be removed, FALSE otherwise.

Notes

You have to do a final check for messages on your AppMenuItem message
port as messages may have arrived between the last time you checked this
and the call to this function.

RemoveAppWindow()

Synopsis

BOOL RemoveAppWindow(
         struct AppWindow * appWindow );

Function

Try to remove an AppWindow from workbench.library's list of AppWindow:s.

Inputs

appWindow  --  pointer to AppWindow structure got from AddAppWindow().

Result

TRUE if the window could be removed, FALSE otherwise.

Notes

You have to do another check for messages on the AppWindow message port
you specified at the AppWindow creation time (AddAppWindow()) after the
window is removed as it may have arrived messages between the last time
you checked and the call of this function.
    Before the AppWindow is removed, all its drop zones will be removed.
Thus there is no need to call RemoveAppWindowDropZone() explicitly.

RemoveAppWindowDropZone()

Synopsis

BOOL RemoveAppWindowDropZone(
         struct AppWindow * aw,
         struct AppWindowDropZone * dropZone );

Function

Try to remove a drop zone from an AppWindow.

Inputs

appWindow  --  pointer to the AppWindow (as returned by AddAppWindow()) to
               try to remove the drop zone from; a value of NULL will
               result in no operation
dropZone   --  pointer to an AppWindowDropZone (as returned by
               AddAppWindowDropZone()); a value of NULL will result in
               no operation

Result

TRUE if the drop zone could be removed, FALSE otherwise. In case of
failure, the reason may be obtained from dos.library/IoErr(). This
function may fail if the specified drop zone is not registered with
the supplied AppWindow.

Notes

You must check for drop zone messages for zones that you just removed as
there might have been messages sent between the last time you checked and
the call to this function.

SendAppWindowMessage()

Synopsis

BOOL SendAppWindowMessage(
         struct Window * win,
         ULONG numfiles,
         char ** files,
         UWORD class,
         WORD mousex,
         WORD mousey,
         ULONG seconds,
         ULONG micros );

Function

This function sends the given list of files to a registered
AppWindow's application. If the window is not an AppWindow, nothing
is done.

Inputs

win -  window that should be checked
numfiles - number of files in the attached array of string pointers
files - files "list"

Result

TRUE if action succeeded

Example

char *FileList[] =
    {"images:image1.png", "images:image2.png", "images:image3.png"};

SendAppWindowMessage(myWindow, 3, FileList);

StartWorkbench()

Synopsis

BOOL StartWorkbench(
         ULONG flags,
         APTR ptr );

UnregisterWorkbench()

Synopsis

BOOL UnregisterWorkbench(
         struct MsgPort * messageport );

Function

The workbench application uses this functions to unregister itself
with the library. When it is done, messages will no longer be sent.

Inputs

msgport - The message port of that was earlier passed in to
          RegisterWorkbench().

Result

TRUE if the message port was successfully unregistered, FALSE otherwise.
The unregistration will fail if the message port isn't the same that
was passed in with RegisterWorkbench() earlier or if the passed
in pointer is NULL.

Notes

Note that "Workbench Application" in this context means the program that
is the file manager and handles the GUI of Workbench, not a program that
is started from Workbench!

UpdateWorkbench()

Synopsis

BOOL UpdateWorkbench(
         CONST_STRPTR name,
         BPTR parentlock,
         LONG action );

Function

This function does the "magic" of letting Workbench know that
an object has been added, changed, or removed. The name is
the name of the object, the lock is a lock on the directory that
contains the object. The action determines what has happened.
If UPDATEWB_ObjectAdded, the object is either NEW or has CHANGED.
If UPDATEWB_ObjectRemoved, the object has been deleted.

Inputs

name         - Name of the object (without the .info)
parentlock   - Lock on the object's parent directory.
action       - UPDATEWB_ObjectAdded for a new or changed object
               UPDATEWB_ObjectRemoved for a deleted object

Result

Workbench will update its display, if needed. An object that has
been deleted will be removed from the display. An object that is
new will be added to the respective display if it is not already
there; if it is already there, its appearance will be changed if
necessary.

UpdateWorkbenchObjectA()

Synopsis

BOOL UpdateWorkbenchObjectA(
         STRPTR name,
         LONG type,
         struct TagItem * tags );

BOOL UpdateWorkbenchObject(
         STRPTR name,
         LONG type,
         TAG tag, ... );

Function

Informs the workbench application that an object has changed, and that
it should update it's visual representation.

Notes

This function is TEMPORARY! It will hopefully go away before AROS 1.0,
and it might change it's API several times before that!

Bugs

The existance of this function is a bug itself. It should be removed
once there is a adequate notification API in dos.library that works.
