How to get active view in ArchiCAD API?

hi guys,

Do you know how to get active view?

(I think I need to use API_NavigatorItem, But I couldn't do it)

If you know, please help me

Thank you very much

Hi,

There's no function to get the active view directly as far as I know.

But you can workaround this with using with a View Notification Handler.

You have to register the notification handler in the Initialize function:

ACAPI_Notify_CatchViewEvent (APINotifyView_Opened, API_MyViewMap, ViewNoticationHandlerProc);

This has to be done separately for every API_NavigatorMapID you need. So you'll have to use a bit of trial and error to figure out which ones you'll need.

And the handler would look something like this:

static GSErrCode __ACENV_CALL ViewNoticationHandlerProc (const API_NotifyViewEventType* viewEvent) { switch (viewEvent->notifID) { case APINotifyView_Opened: { // Do something here with `viewEvent->itemGuid` break; } default: break; } return NoError; }

Also the Add-On needs to be registered as a preloaded Add-On. So return API_Addon_Preload in CheckEnvironment.

Hope that helps!

Bernd

Hi @BerndSchwarzenbacher ,

I followed your tutorials, but it still doesn't work? Can you check and tell me where I'm wrong

This is my code:

API_AddonType __ACENV_CALL CheckEnvironment(API_EnvirParams* envir) { RSGetIndString(&envir->addOnInfo.name, ID_ADDON_INFO, 1, ACAPI_GetOwnResModule()); RSGetIndString(&envir->addOnInfo.description, ID_ADDON_INFO, 2, ACAPI_GetOwnResModule()); return APIAddon_Preload; } static GSErrCode __ACENV_CALL ViewNoticationHandlerProc(const API_NotifyViewEventType* viewEvent) { switch (viewEvent->notifID) { case APINotifyView_Opened: { // Do something here with `viewEvent->itemGuid` WriteReport_Alert("View"); break; } default: break; } return NoError; } GSErrCode __ACENV_CALL Initialize(void) { GSErrCode err = ACAPI_Install_MenuHandler(ID_MENU_STRINGS, MenuCommandHandler); API_NavigatorMapID mapId = API_MyViewMap; ACAPI_Notify_CatchViewEvent(APINotifyView_Opened, mapId, ViewNoticationHandlerProc); if (err != NoError) DBPrintf("3D_Test:: Initialize () ACAPI_Install_MenuHandler failed\n"); return err; } // Initialize

I'm quite busy right now, but tomorrow I'll have more time to take a closer look.

Please specify what exactly is not working.
What did you try to do in the program and what did you expect to happen?

From a quick look at the code it seems OK. Maybe try different NavigatorMapIDs like API_ProjectMap, API_UndefinedMap, API_PublicViewMap.

I did a few quick tests by opening different view maps in Archicad and checking which map ID is used in the triggered view notification.
Here's the mapping of Archicad Navigator Map -> API_NavigatorMapIDs when listening to APINotifyView_Opened:

Project Map (Stories, Elevations, Schedules, ...) -> API_ProjectMap
API_PublicViewMap
Layout Book & Publisher Sets -> API_UndefinedMap

Couldn't find anything that triggered the API_MyViewMap. I'm sure I used it before for something, but can't remember now.

Hope that helps,
Bernd
