Set*UIColor, etc.

The inseparable changes necessary to support live color updating across the
system in a sane, safe, and performant manner.

BView gains:

HasSystemColors()
HasDefaultColors()
AdoptSystemColors()
AdoptParentColors()
AdoptViewColor(BView*)
SetViewUIColor(color_which, float tint)
SetHighUIColor(...
SetLowUIColor(...
ViewUIColor(float* tint)
HighUIColor(...
LowUIColor(...
DelayedInvalidate()

BWindow gains a simple helper method:
IsOffscreenWindow()

BMessage gains:

AddColor()
FindColor()
GetColor()
HasColor() * allegedly this API is deprecated, but I implemented it anyway
ReplaceColor()
SetColor()

Previous private ColorTools methods are made public and moved into GraphicsDefs:

mix_color, blend_color, disable_color

These are fully compatible with BeOS dan0 R5.1 methods and are just code cleanup
of BeOS example code under the OpenTracker license.

In addition, four new colors are created:
B_LINK_TEXT_COLOR
B_LINK_HOVER_COLOR
B_LINK_ACTIVE_COLOR
B_LINK_VISITED_COLOR

These changes are documented in their proper user documentation files.

In addition, due to a history rewrite, B_FOLLOW_LEFT_TOP has been defined and
used in lieu of B_FOLLOW_TOP | B_FOLLOW_LEFT and is included in this commit.

On the app_server side, the following has changed:

Add DelayedMessage - a system by which messages can be sent at a scheduled time,
and can also be merged according to set rules. A single thread is used to service the
message queue and multiple recipients can be set for each message.
Desktop gains the ability to add message ports to a DelayedMessage so that
said messages can target either all applications or all windows, as needed.

Desktop maintains a BMessage which is used to queue up all pending color changes
and the delayed messaging system is used to enact these changes after a short
period of time has passed. This prevents abuse and allows the system to merge
repeated set_ui_color events into one event for client applications, improving
performance drastically.

In addition, B_COLORS_UPDATED is sent to the BApplication, which forwards the message
to each BWindow. This is done to improve performance over having the app_server
independently informing each window.

Decorator changes are live now, which required some reworking.

Added BTextControl::TextLength() method.

Changes to BTextControl for docs.

Also remove the non-ControlLook drawing code.

Introduce "invalid" text controls.

* MarkAsInvalid is used to enable or disable the mark
* The B_INVALID BControlLook flag is used
* invalid BTextControls are drawn with a red border.
* You ar encouraged to let the user know more precisely what's wrong, by
showing an helpful error message next to the control or in a tooltip.

BControl subclasses: Override SetIcon()

... and implement Perform() action for potential later use.

Interface Kit: Adjust max size and default alignment...

...on controls where it makes sense:
- BRadioButton and BCheckBox now return their preferred size as their
maximum.
- BRadioButton, BCheckBox and BTextControl now use left alignment by
default, as this is the most common use case for them.

The text control is now more flexible with its layout items.

* Before, you had to have both, the text view layout item, and the label
layout item or else nothing would ever be visible.
* Now you can only create the text view item, and it will still work.
* Also, no matter the order you added the layout items, they would always
put the label on the left, and the control to the right.
* You can place the label and text view layout items anywhere now, although
you should keep in mind that the view spans over their frame unions; IOW
they should always adjacent to each other, but not necessarily horizontally
and left to right.
* No longer uses a fixed label spacing, but utilizes
BControlLook::DefaultLabelSpacing() instead.
* However, the spacing is always added to the right of the label, no matter
how you place it in the layout. Maybe one wants to add a SetLabelTextViewGap()
like method.

Make archiving hooks protected in layout classes.

Furthermore,
* remove a stray blank line in Layout.cpp
* make BLayoutItem::SetLayout() private, as it should have been

Replace remaining InvalidateLayout()'s with LayoutInvalidated(). Also do a bit of cleanup/move methods around.

Updated BTextControl and its custom BLayoutItems. Also a bit of style cleanup. Broke up BTextControl::_InitData() method into _InitData() and _InitText() and moved initialization of the BTextView there.

Finished unifying the Interface Kit headers:
* Fixed copyrights (puncuation and capitalization, removed authors from
headers)
* Updated indentation style
* Unified pointer/reference style
* Re-ordered some methods for better grouping where it could be done
(abd adopted source accordingly)
* Small coding style fixes here and there

No functional change intended.

* Implemented a lot of layout related methods and resolved a few TODOs by
doing a lot of these things the same way as BMenuField are already doing.
Perhaps a private helper class could be refactored from these two controls
to avoid duplicating a lot of this code, although there are a few subtle
differences here and there.

These changes make a BTextControl behave properly in the layout management
frame work, in case CreateLabelLayoutItem() and CreateTextViewLayoutItem()
are _not_ used to layout the BTextControl.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@27584 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Updated header indentation
* Removed unused fClean member
* Got rid of fSkipSetFlags member by simply calling the BView::SetFlags()
directly where fSkipSetFlags was supposed to prevent the custom
implementation.
* Added some debugging facilities.
* Used the layout friendly constructors of BControl where appropriate.
* Used B_FOLLOW_ALL for the child text input, it should be more correct.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@27576 a95241bf-73f2-0310-859d-f6bbb57e9c96

BTextControl:
* Placed _BTextInput_ into BPrivate namespace.
* Made _BTextInput_::AlignTextRect() smarter, it centers the line vertically,
for the case that the BTextControl has a larger label font. Improved insets
for asthetics.
* Used _BTextInput_::AlignTextRect() consistently in BTextControl, no more
custom calls to SetTextRect(). Account for minimum vertical inset of 2
pixels in GetPreferredSize().
* Consistendly select all text when gaining focus in _BTextInput_.
* Override MouseDown() in case the control did not have focus before, or else
BTextView::MouseDown() will deselct the text again and place the cursor.
(in line with BeOS behavior)
* Removed unused fBool member from _BTextInput_ and other cleanup.

BTextView:
* Reimplemented BTextView::_AutoResize() so that it works well with
BTextControl and autoscrolling when the alignment is not B_ALIGN_LEFT.
I needed two new members for this, fLeftInset and fRightInset which are
the original insets from the fTextRects. It might currently be broken
for renaming things in Tracker, I will have to check. _AutoResize() no
longer messes up the fTextRect insets.
* Fixed stray carrets sometimes being left over, mostly when auto scrolling,
but I observed them in other cases as well.
* Prevent negative scrolling offsets when autoscrolling. Fixes weird scrolling
offsets when navigating to the left.
* Reset scrolling to B_ORIGIN when SetText() is called. Fixes for example
starting to type in the middle of the control in Vision when entering new
text and autoscrolling was triggered before.

* make the text view layouting more robust, draw the frame around the
text view, ignore the divider for this (application code could layout
the textview itself, and fDivider might not be maintained)
* change Draw() and TextInput::MakeFocus() accordingly

this fixes the weird placement of text controls in Beam

asked for IsEnabled() before it was set.

BTextControl::AttachedToWindow() set wrong colors in case the control was
disabled (unlike SetEnabled()). They are now both using the correctly working
_UpdateTextViewColors() method.
