VirtualKeyboard: Fold KeyboardLayoutView back into the Keymap preferences one.

Only one #ifdef, the rest is all in basic if-tests. Relatively minimal changes,
and now the virtual keyboard device gets all the improvements made to the keyboard
layout view over the last 6 years.

Keymap: remove flickering workarounds, small fixes

Part of #15623.

Keymap: static functions back to private methods

keymap: limit set of left/right swap options

For Shift, Control, Option, and Command assume that you want to shift
on the same side, left-for-left, right-for-right. The Menu key is
available on either the left or right side, and lock keys can be
swapped with any other modifier left or right.

If we have multiple unmapped modifiers we need to do a little extra
work to figure out which of the unmapped modifiers to swap with.

Convert private class member methods to static functions.

Also update copyright info

Keymap: Allow you to unset modifier keys

Selecting the marked menu item will unset the mapping for that modifier.

We can't rely on there being a unique mapping for a key (more than one
could be set to 0 aka unset) so we have to set the menu item names based
on the interface defs constants intead.

Keymap: activate popup for all modifiers

not just those that have a modifier key mapped to them already

Also check for control+click == RMB

Keymap: swap modifiers keys via context menu

When the user right clicks on a modifier key pop up a menu listing the
available modifiers. When the user selects a modifier from the menu swap
the key with the selected modifier. This provides an alternative way to swap
modifier keys other than drag&drop that works for just modifier keys.

* fix warnings in Keymap preflet about hidden virtual by renaming SetFont()
to SetBaseFont() (and fFont to fBaseFont)
* enabled -Werror for all preflets

* Some keymap labels now have an abbreviated version that is used when the key
gets too small for the full text.
* This closes enhancement ticket #4024.

* avoid key highlighting unless the preflet window is active, at least
I've found it pretty silly that the Keymap preflet would document all my
keypresses although I'm doing something elsewhere

* dead keys can now be enabled/disabled via middle mouse button
* fDragKey must be reset in MouseUp() as otherwise it is not possible to
drag a key from one keymap to the textview and then from the textview to the
same key of another keymap
* _HandleDeadKey() now ignores modifier keys as otherwise dead keys that
required pressing a modifier (like the tilde on the German keyboard) failed
to highlight the resulting characters
What's still missing is a way to edit the resulting characters for each dead key, but I am not yet sure how to do that in an elegant way

changing keymaps this way.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29930 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added ability to change modifier keys (per drag and drop).
* Added button to switch shortcut modifier keys.
* Added option to make the KeyboardLayoutView non-editable.

* Works around a race condition/bug/design issue in our layout engine:
sometimes the size isn't set in AttachedToWindow() yet, and the first
FrameResized() comes after the first Draw(). We now relayout in Draw()
in case the size changed since last time.

* Now uses an offscreen bitmap for flicker free drawing.
* Only trigger a redraw on B_MODIFIER_CHANGED if something actually changed.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29747 a95241bf-73f2-0310-859d-f6bbb57e9c96

The button and menu field draw routines take a background color into account,
which makes the resessed frame blend better with the surroundings. This can
be seen best in Keymap, where a different color is set on some buttons, but
the resessed frame should still be the same across all those buttons.

* The L-shaped "enter" key can now also be drawn almost right (uses
BControlLook plus some clipping to do its magic).
* Fixed scancode only mode of the keyboard layout view.
* Fixed filter thanks to Rene.

* The default drag&drop action is now copy, if you drag with the second mouse
button, you switch the keys.
* Switching the same key with different modifiers held works now.
* The drop target is now reevaluated when a modifier key is pressed, as the
key originating the drag cannot be its target (but only with the same
modifiers pressed).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29704 a95241bf-73f2-0310-859d-f6bbb57e9c96

* The message filter now does not do anything anymore when the source keymap
matches his own (field now added to the KeyboardLayoutView fake B_KEY_DOWN
messages).
* The default action for keyboard to keyboard drag&drop is to switch the keys
now.
* When a key is overwritten by a drop, the old key is now sent to the text
view, so that it's not lost (if that was a mistake you can now easily revert
it without having to press the "Revert" button and lose all changes).
* Cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29702 a95241bf-73f2-0310-859d-f6bbb57e9c96

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29699 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added the ability to set a target that will receive fake B_KEY_DOWN
messages generated when pressing the keys.
* The font size is now adapted to match the key size better, maximum size is
the current plain font.
* The keys you drag around now generate a useful B_MIME_DATA message, that other
views can accept as well.
* Implemented support for changing the keymap via drag&drop.
* Added SetFont() method to change the font used by the keys.

interaction, draw symbols differently.

* Work in progress commit of the Keymap rework. Should not disturb the
existing code.
