Hi all,
I want to send my desktop replicant a BMessage, but I can't find the shelf.
The docs are not clean on this and I have looked in the Haiku source
code to make sure I am right about the instance hierarchy.
In (my) theory, the following code should target the Shelf:
BMessage request(B_GET_PROPERTY);
BMessage reply;
request.AddSpecifier("Shelf");
request.AddSpecifier("View", "desktop"); //Name from DesktopWindow.cpp
request.AddSpecifier("Window", "Desktop"); //Name from DesktopWindow.cpp
BMessenger to("application/x-vnd.Be-TRAK", -1);
status_t s = to.SendMessage(&request, &reply);
Gives me the error:
message[0] = string("Cannot find view at/with specified index/name.", 47 bytes)
message[1] = string("Index not in range for the data set", 36 bytes)
Replacing the view name for an index like this: AddSpecifier("View",
1) gets me further, but still an error:
message[0] = string("This window doesn't have a shelf", 33 bytes)
message[1] = string("Name not found", 15 bytes)
error = int32(0x80000007 or -2147483641)
What am I doing wrong here? Am I forgetting a specifier?
Greetings
Mauro
