Slider: Style fixes

Pointer style
Newlines
Indentation
Compare against NULL or 0 explicitly
use single floating point precision for float literals (i.e. use 0.0f)

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.

BControl subclasses: Override SetIcon()

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

Minor cleanup.

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

* Reuse the check for changed location which decides whether
to Invoke() in MouseUp() in the code path for keyboard control.
Should fix ticket #6792, but I have not actually tested it.
* Don't post notification values in KeyDown() when the value did
not change because it was constrained between min and max values.

for binary compatibility).
* Always round the bar thickness, or we get drawing artefacts.

Implemented a new look for the Haiku interface controls. It was
overheard that they looked too ninety-ish.
TODO: The code behind this is work in progress. The basic idea
is to extract all drawing code into a new class BControlLook,
of which there is a global instance be_control_look, instantiated
in InterfaceDefs.cpp. At the moment, all the old drawing code is
still there, and the usage of be_control_look is inside if-bodies
checking the instance against NULL. In another words, by not
instanitating be_control_look, you can revert back to the old look.
BControlLook's job is to provide reusable methods for drawing
certain types of frames, backgrounds and labels, so that application
developers can make controls that re-use the same drawing code
as built-in controls and adopt to changes made there. I have added
the notion of "borders". Each of the frame drawing methods can be
made to draw certain borders only, which is supposed to help when
controls shall visually attach. This feature is not fully explored
at all ATM.
TODO: Update BColumnListView header view and BStringItem text
spacing. Update other apps where it makes sense to use BControlLook.
For the moment, only Tracker and LaunchBox are updated. More...
NOTE: The new look is not very radically different, so that existing
apps do not immediately look too ugly or out of place.

bonefish + zooey:
* Fixed a general problem with respect to overriding of the reserved
virtual function slots: instead of statically invoking the method
that corresponds to the reserved slot on the class that contains the
slot, we now invoke the virtual Perform() method. Perform() then dispatches
the method invocation to the "proper" class, i.e. the highest class in the
hierarchy that actually implements the requested method.
This fixes a crash in apps that use liblayout's MSlider class and
should fix one or other spurious bug with old apps or libraries, too.
* added new header folder 'binary_compatibility' that contains files that
define the method codes and data structures required by Perform()
* looked for and implemented all used reserved virtual slot functions to
invoke Perform() where necessary or to pass on the method call statically
(for slots that were already maintained by Be)


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28124 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Changed the signature of UpdateText() to return a "const char*" (char*
really makes no sense if the pointer belongs to the derived class and
only confuses). Note this change does not affect binary compatibility.
* Introduced a new MaxUpdateTextWidth() virtual method which is really
necessary to handle the update text correctly in the layout.
* Introduced a new UpdateTextChanged() method which can be called to
notify the control of a changed update text. Internally, SetValue()
also uses it.
* Handle the width or height of the UpdateText() correctly in the layout.
For horizontal layout, the width was forgotten to be included in
GetPreferredSize(), for vertical layout, it was completely broken before.
* Handle invalidation correctly when the UpdateText() changes.
* Remove the arbitrary insets for labels from the border the control. This
makes it easier to align the control's labels with other controls.

First round of BSlider fixes to be more layout friendly:
* Improve the minimum size calculation and cache it.
* Invalidate the layout on various property changes that require it.

Vertical BSliders are very broken... that's up next.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26441 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added layout friendly constructor
* Use constructor lists for initializing members
* Simplified initial SetBarColor()
* Update the offscreen view with ViewColor() and LowColor(), someone might
have changed it after AttachedToWindow() was called.
* Cleanup here and there


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26440 a95241bf-73f2-0310-859d-f6bbb57e9c96

BSlider had code for doing double buffered drawing, but was
disabled by default. Appears to work correctly though, so
enabling it since it produces far less flicker here.



git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24255 a95241bf-73f2-0310-859d-f6bbb57e9c96

Changes to let updates happen less frequently:
* _ContrainPoint() was broken as it could never change the point it was supposed
to contrain.
* MouseDown() no longer sends a notification message automatically (only if it
changed something)
* MouseMoved() and synchronous MouseDown() will now only send modification messages
if something actually changed (not for every mouse update).
* After key presses, the invokation message is only sent when the value changed.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19697 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Now draws the UpdateText() label as well (was obviously forgotten before).
To reduce the number of calls to UpdateText(), the value returned is now
buffered. This fixes bug #443.
* SetValue() now calls UpdateText() and also invalidates the region where
that label is drawn.
* In asynchronous mode, B_NO_POINTER_HISTORY is set now for tracking.
* Increased minimum snooze time in synchronous mode.
* Minor cleanup, renamed fMinLimitStr to fMinLimitLabel, etc.

Improved BSlider class:
- rewrote GetPreferredSize(), it now actually works correctly
- BSlider is certainly not supposed to resize itself on creation
- fixed BarFrame() and ThumbFrame() to support a different view frame
than the ideal one
- added SetBarThickness() support
- refactored constraining the mouse point to _ConstrainPoint() - it's
now used by MouseDown() and MouseMoved() - because of that, tracking
now works with vertical sliders as well
- still has some drawing problems, but less
- _ReservedSlider4() was defined public for the R5 build
Cleanup, more or less rewrote the header.
