/****
|
||
|
|
* Callback Prototypes:
|
||
|
|
* --------------------
|
||
|
|
* LWShelfLoadOkFunc - Asks the subscribed client if it is ready to accept
|
||
|
|
* loading a preset.
|
||
|
|
* LWShelfLoadFunc - Called to have the client load settings
|
||
|
|
* LWShelfSaveFunc - Called during save to obtain client settings
|
||
|
|
*
|
||
|
|
* These load and save callbacks provide for loading and
|
||
|
|
* saving client settings using the LW Load and Save State (LWIO.H)
|
||
|
|
* OR as a separate data file.
|
||
|
|
*
|
||
|
|
* Use of the LWIO states is recommended.
|
||
|
|
*
|
||
|
|
* Which format is used depends on the subscription flags
|
||
|
|
* where SHLF_BIN or SHLF_ASC uses the corresponding LWIO
|
||
|
|
* load/save states and SHLF_SEP indicates the client will
|
||
|
|
* save data to a separate file in whatever manner best suits
|
||
|
|
* its needs. The filename argument to the Load/SaveFunc
|
||
|
|
* callbacks is the filename the client should use for this
|
||
|
|
* activity.
|
||
|
|
*
|
||
|
|
* API Description:
|
||
|
|
* ----------------
|
||
|
|
* subscribe - Adds a client to the Preset Shelf and returns a client ID.
|
||
|
|
* unsubscribe - Unsubscribes the client. Clients should, at a minimum,
|
||
|
|
* do this when its instance is destroyed.
|
||
|
|
* open - Opens the Preset Shelf window and sets focus to the client.
|
||
|
|
* close - Closes the Shelf.
|
||
|
|
* setContext - Grabs the focus of the Shelf. This differs from the Open
|
||
|
|
* method by making the client the active client but this
|
||
|
|
* does not open the Shelf window.
|
||
|
|
* addPreset - Called by the client to add a preset settings
|
||
|
|
* addNamedPreset file to the Presets Shelf. The 'img' is an
|
||
|
|
* LWImageID to use as the preset's thumbnail. The
|
||
|
|
* 'parms' is a NULL terminated list of string
|
||
|
|
* parameter tags which can be used to conditionally
|
||
|
|
* load settings from the preset.
|
||
|
|
* (Independent Operations)
|
||
|
|
* load/save - These load/save preset settings files to an
|
||
|
|
* arbitrary location specified by 'filename'. As part
|
||
|
|
* of the shelf API, the load and save methods reuse
|
||
|
|
* the client subscription settings (like userdata,
|
||
|
|
* callbacks, etc.). If 'prompt_user' is true and the
|
||
|
|
* preset contains a parameter list, this will prompt
|
||
|
|
* user for input.
