- NAME
- Class: commodityclass
- Superclass: ROOTCLASS
- Include File: <bgui/bgui_cx.h>
-
- FUNCTION
- To provide a BOOPSI based interface to the commodities.library.
- This class will allow you to setup and maintain a simple broker with
- simple hotkeys. The attached hotkeys can also be disabled separately
- and enabled.
-
- commodityclass/CM_ADDHOTKEY
-
- NAME
- CM_ADDHOTKEY -- Add a hotkey to the broker.
-
- SYNOPSIS
- err = DoMethod( obj, CM_ADDHOTKEY, desc, id, flags );
-
- ULONG err;
- STRPTR desc;
- ULONG id;
- ULONG flags;
-
- FUNCTION
- This method must be used to attach hotkeys to the broker. The
- hotkey is defined with an input description string just like that used
- by the amiga.lib HotKey() function.
-
- INPUTS
- desc - This must point to a string in which the hotkey is
- described. The input description string is the same string as
- you would pass the HotKey() routine from the amiga.lib link
- library.
-
- id - This must be an integer which represents the ID of the
- key. This must be a unique value as this ID will be used to
- identify the key. Please note that you should keep the ID
- between 1 and 65535 (I.E. In the lower 16 bits.) if you use
- the V40 style of message handling.
-
- flags - This field may have any of the following flags set:
-
- CAHF_DISABLED - When set the key is added to the broker but it
- is disabled from usage.
-
- RESULT
- err - TRUE for success, FALSE for failure. When FALSE is returned
- you can use the COMM_ErrorCode attribute to find out what it
- was that failed.
-
- EXAMPLE
- Object *broker;
- #define ID_SF1 1
-
- /*
- * Add shift+f1 as a hotkey to the
- * broker object.
- */
- DoMethod( broker, CM_ADDHOTKEY, "shift f1", ID_SF1, 0L );

-
- ULONG err;
- ULONG id;

-
- INPUTS

-
- RESULT

-
- commodityclass/CM_MSGINFO
-
- NAME
- CM_MSGINFO -- Examine commodity broker messages.
-
- SYNOPSIS
- cont = DoMethod( obj, CM_MSGINFO, type, id, data );
-
- ULONG cont;
- ULONG *type;
- ULONG *id;
- ULONG *data;
-
- FUNCTION
- To get the pending commodity messages and extract the necessary data
- from them. You supply storage space for the data you need to know.
-
- INPUTS
- type - When non-NULL the result of CxMsgType() on the commodity
- message is stored here.
-
- id - When non-NULL the result of CxMsgID() on the commodity
- message is stored here.
-
- data - When non-NULL the result of CxMsgData() on the commodity
- message is stored here.
-
- RESULT
- CMMI_NOMORE when all messages have been processed. You must keep
- calling this method until CMMI_NOMORE is returned.
-
- Since V40 the class can also return any of the following return codes:
-
- CMMI_KILL -- Uppon receiving this return code you should
- remove yourself from the system and terminate.
-
- CMMI_DISABLE -- This return code tell's you that the broker is
- disabled. At the time you get this message the broker
- has already been disabled.
-
- CMMI_ENABLE -- When this is returned the broker is enabled. At
- the time you get this message the broker has already
- been enabled.
-
- CMMI_UNIQUE -- When this is returned another commodity has
- been attemted to run using your broker name. You
- should let the user know this happened. Usually you do
- this by popping up your GUI.
-
- CMMI_APPEAR -- This is returned when you are requested to open
- up the GUI of the commodity.
-
- CMMI_DISAPPEAR -- This will be returned when you are requested
- to close down the GUI of the commodity.
-
- Any return code other than these is the ID of a CXM_IEVENT message.
- This normally is the ID of an attached hotkey.
-
- EXAMPLE:
- Object *com_obj;
- ULONG mask = 0, type, id, data, rc;
- BOOL running = TRUE;
-
- GetAttr( COMM_SigMask, com_obj, &mask );
-
- do {
- Wait( mask );
- while (( rc = DoMethod( com_obj,
- CM_MSGINFO,
- &type,
- &id,
- &data )) != CMMI_NOMORE ) {
- switch ( type ) {
- ...
- }
- }
- } while ( running );
-
- /* Or (V40 style) */
-
- do {
- Wait( mask );
- while (( rc = DoMethod( com_obj,
- CM_MSGINFO,
- NULL,
- NULL,
- NULL )) != CMMI_NOMORE ) {
- switch ( rc ) {
- ...
- }
- }
- } while ( running );
