Hi,
I'm new to IB.
I'm trying to find by which magic "NSWindow * imageCaptureWindow;",
member of "@interface Controller : NSWindowController",
gets initialized by the following code :
[NSBundle loadNibNamed: @"ImageCapture" owner: self];
This variable isn't initialized anywhere in the code, so it must be IB
which does it. But, contrary to the window's views, it isn't even an IBOutlet.
The only connection/binding/whatever I can see in IB for this window is
the delegate to "point to" the owner, which is the previously mentionned
Controller.
Also, for the "Device Browser View", where in IB can I find how "mode" is set to
"IKDeviceBrowserViewDisplayModeTable" ?
I (think I) do understand how bindings works, but not how to retrieve the
pertinent information in IB...
Any help would be appreciated, IB is so mysterious to me !
Salut Eric.
I'm sure that there are some who will be able to better explain it than myself but, to
make a long story short, when you call loadNIbNamed:, the method will connect all the
instance variables of the "owner" that you have declared to be IB outlets with
the UI objects that you did create in IB, after they are instantiated. How does the
method do that? If they are no setter for a particular ivar, it will just set the ivar
directly. This is also probably explained in the documentation.
HTH!

Salut Laurent,
that's what I did understand, but...
Somewhere in IB I should find the name of that instance variable
("imageCaptureWindow"),
so loadNibNamed: knows *which* variable to assign to, which I don't find.
To establish myself a connection, the instance variable has to have the
IBOutlet attribute,
which "imageCaptureWindow" lacks.
Let's look at the scannerView. The ivar is declared as "IBOutlet IKScannerDeviceView
* scannerView",
and in IB I can see a connection in "Referencing Outlets", that's called "scannerView",
of/to the "File's Owner".
That's clear to me.
I expect to find something similar for the window, but I don't...
Yet it works... but I can't figure out how.
Thanks.
