Hello,

I've encountered a strange problem. I've laid out a small GUI (window
with several buttons), connected things in IB, added a little code to
override the keyDown: so that I can take control over what keys are used
to cycle the focus/firstResponder, made the first button the
initialFirstResponder etc. I did all that on my (G4) laptop during a
train trip and everything works like a charm but... the same project
transferred to and built on a desktop (G5) machine exhibits very much
different behaviour:

- the first button (set as initialFirstResponder) doesn't seem to get
the focus (and ring) on startup (works perfectly on the laptop)

- I can't neither TAB nor use my (arrow) keys to cycle through the
buttons (this also works perfectly on the laptop)

XCode env is the latest 2.4.1 in both cases. OS versions are the same.
Yes, there is a difference in the CPUs but both are PPC and we're
talking about high-level fundamentals rather than CPU specific low-level
stuff here.

Is there something I should be aware of that could cause those
anomalies? Yes, I cleaned the project before rebuilding...

Suggestions appreciated.

Buttons aren't tab-navigable by default - have you enabled "full keyboard
access" for all controls on your laptop by any chance? (System Preferences/
Keyboard & Mouse/Keyboard Shortcuts).

Sherm,

a) thank you for that quick hint

b) now I am ashamed - in fact that was the case!

The only excuses I have is that:

a) I set it ages ago on both machines but somehow it got turned off on
the desktop, possible by an accidental ^F7 hit or so...

b) Neither TABs nor my programmed keys worked, which I would rather
expect to work regardless of this setting (in fact they also work only
when the full control is enabled)

c) It's almost 2am here now... ;-)

But all that raises another question: does the above mean that I have no
easy way of selecting the buttons with a keyboard whenever the user has
the default settings in his prefs?

Or what should I do rather than

[[self window] selectKeyViewFollowingView:self];

??

I may try addressing all the buttons directly or other experiments but
if you happen to know...

Regards.

It means the user can't tab to a button and trigger it with the space bar,
yes. But you can assign a keystroke combination to the button - cmd-a or
whatever - in IB.

You mean the keyEquivalent-s? Yes, I know that (I'll have another
question regarding those) but What I want is that the user could tab (or
use arrow keys) and hit space (or RETURN) even if the settings are
default. For now I think I'll experiment with addressing the buttons
with makeFirstResponder as that seemed to bring the focus ring to the
given button even if the full keyboard access was turned off. Not really
elegant as I probably will have to maintain a (redundant) list of
controls on my side but I have no other ideas as of today.
