In src/kernel/qapplication_mac.cpp (Qt 3.3.3), there is the following
array definition:
static key_sym modifier_syms[] = {
{ shiftKey, MAP_KEY(Qt::ShiftButton) },
{ rightShiftKeyBit, MAP_KEY(Qt::ShiftButton) },
{ controlKey, MAP_KEY(Qt::MetaButton) },
{ rightControlKey, MAP_KEY(Qt::MetaButton) },
{ cmdKey, MAP_KEY(Qt::ControlButton) },
{ optionKey, MAP_KEY(Qt::AltButton) },
{ rightOptionKey, MAP_KEY(Qt::AltButton) },
{ kEventKeyModifierNumLockMask, MAP_KEY(Qt::Keypad) },
As you can see, it hardcodes the relation between OSX keys and Qt
equivalents. In particular, the 5th entry maps Command to Control.
This is used unconditionally in the code just below.
So fixing this would mean adding a way to provide a different
translation table.
Actually, there would be a way to work around this: add OSX-specific
code that hooks into the event loop to rewrite the keyboard event with
different modifiers. For example, if the modifier cmdKey is used,
change it to controlKey, so that Qt translates it later to
Qt::MetaButton. This will lead unfortunately to bad shortcuts
displayed in the menus (and it is an ugly hack).
Note also that LyX only uses the Meta, Control and Shift modifiers. We
should maybe investigate whether we want to use the Alt modifier too.
If you want to complain to trolltech, you should detail what are the
drawbacks of their implementation. AFAIK, one big problem is that the
accented characters accessible usually through the option key cannot
be accessed anymore.
Other people have complained that the current bindings are not nice
for people using emacs bindings. Is that your case?
Hope this helps.
