BeControlLook: Fix app integration drawing issues

Update BTab::DrawTab() to pass the current index, the index of the
selected tab, and the index of the first and last tabs into
BControlLook::DrawActiveTab() and BControlLook::DrawInactiveTab().
This allows you to draw tabs differently in your BTab or BControlLook
subclass in many different circumstances.

Modify BControlLook API to add indexes to DrawActiveTab() and
DrawInactiveTab() like so:

void DrawActiveTab(..., int32 index = 0, int32 selected = -1,
int32 first = 0, int32 last = 0);
void DrawInactiveTab(..., int32 index = 0, int32 selected = -1,
int32 first = 0, int32 last = 0);

These extra indexes are not used by HaikuControlLook which relies only
on if the tab is active or inactive to draw.

Add IndexOf(BTab* tab) method to BTabView and document it to get the
index of the current tab in BTab::DrawTab(). Also add a warning in the
BTabView::DrawTab() method not to use the position and full parameters
anymore, use BTabView::IndexOf(), BTabView::Selection(), and
BTabView::TabCount() to get the info you need.

Using a dynamic_cast to a BTabView in BeControlLook to determine if the
view is derived from a BTabView didn't work in the case of WebPositive.
Furthermore, WebPositive does custom tab drawing which needed to be
updated for alternative control look. These index parameters passed from
BTab to BeControlLook allow us to draw the tab like BeOS without relying
on a dynamic_cast to BTabView to get the info.

Reproduce the functionality described above for BTab in WebPositive's
custom tabs. Eliminate no longer needed code in favor of using indexes.
Update WebPositive custom tabs to use BControlLook::DrawTabFrame()
instead of BControlLook::DrawInactiveTab() matching the update made in
BTabView.

In BeControlLook::DrawTabFrame() fill rect with base color, WebPositive
doesn't draw any tab background, so it expects this work to be done for
it.

Eliminate hasFrames variable from WebPositive.

Rename TabSelected(index) to UpdateSelection(index) in WebPositive to
better reflect its purpose.

Adjusted HaikuControlLook::DrawInactiveTab() to draw the tab borders more
selectively. Only draw border if left border is set for top and bottom tabs
or top border is set for left and right tabs. Undo no longer needed frame
manipulation border drawing workaround in HaikuControlLook::DrawTabFrame().

Draw scroll bar triangle without using DrawArrowShape().

Unlike in HaikuControlLook, DrawArrowShape() is used to draw arrows in
BOutlineListView and menus distinctly from how it draws arrows in scroll
bars. Draw our distinct arrows in DrawSrollBarButtons() instead.

This fixes overflow of time edit up-down arrows in Clock prefs and the
collapse-expand arrow in Deskbar not being vertically centered.

In DrawBorders() only inset if we actually draw the border.

Fix alignment issues with DrawSliderThumb dots for example in
MediaPlayer volume knobs.

Draw using line arrays calling AddLine instead of StrokeLine in
several places.

DrawMenuBar() extends to draw final pixel which eliminates an extra
lines at the end of menu bars.

Truncate button labels better fixing a few issues for example keymap
keyboard layout button labels. Button insets has been updated a bit
to fix drawing issues with buttons missing a border.

Using a dynamic_cast to a BButton to determine if a view is a button
in BeControlLook didn't work in the case of the keymap label. Look for
B_FLAT, B_HOVER, or B_DEFAULT_BUTTON flag in BeControlLook::DrawLabel()
to draw the label inverted on click. Pass the B_FLAT flag from Keymap
keys when drawing using BControlLook so that the label is inverted.

IK: Update scroll bars for alternative control look

Scroll bars should look and work identically to before on
HaikuControlLook.

Add DrawScrollBarButton() and DrawScrollBarThumb() and
DrawScrollBarBorder() methods. These methods are used to draw scroll
bars in a generic way so that they can be drawn differently by alternative
control look's (e.g. BeControlLook). Also it gives us back drawing of
scroll bar knobs. However the knob setting is not exposed in the
interface in this commit.

These methods are in addition to the 2 existing DrawScrollBarBackground()
methods that draw the scroll bar background. One draws the area above and
below the thumb and the other is called by the first to actually draw the
area.

The rest of the drawing besides the backgrounds was being done in
BScrollBar before. To draw the scroll bar arrows and thumb we were recyling
other ControlLook methods, while this worked well enough on HaikuControlLook
it wasn't flexible enough for alternative control looks.

DrawScrollBarButton() is used to draw the four scroll buttons and is
typically (so far) used in combination with DrawArrowShape().

DrawScrollBarThumb() draws the scroll bar thumb.

DrawScrollBarBorder() draws a 1px border around the entire scroll bar,
potentially B_KEYBOARD_NAVIGATION_COLOR if focused (although this is
feature not currently used.)

Draw unscrollable scroll bars as if they were disabled including the
buttons with their arrow shapes, background, and thumb.

Add FBC backwords compatibility macros in ControlLook.cpp

BControlLook: Move tab frame drawing into DrawTabFrame()

The tab frame is drawn behind the tabs.

Create a new DrawTabFrame method in BControlLook and HaikuControlLook
that draws the tab frame background.

Until now we've been reusing the DrawInactiveTab method to draw the tab frame
in BTabView. While this works on HaikuControlLook, it doesn't work on other
ControlLook's (such as BeControlLook) that draw their tab frame differently.

Add FBC method to preserve binary compatibility on gcc2 and gcc4.

Move DrawTabFrame method to where _ReservedControlLook1 was in header.

Set rect to area of tab frame in TabView instead of doing the
calculation in HaikuControlLook so that others may benefit.

Interface Kit: Make BControlLook a proper pure-virtual base class.

All of its prior functionality has been moved into HaikuControlLook.
This paves the way for customizeable control looks, which I intend to implement
in the future as part of decorators.

This is being pushed now because libbe ABI was already broken due to the
Notifications changes, so this is riding that so we only have to do a mass
rebuild once.

BControlLook: Make all public methods virtual.

Solves a "TODO before R1". Breaks ABI, but almost nothing outside the
tree uses it.

ControlLook: Add side parameter to tab drawing functions.

BTabView: Rename border param to borderStyle

BTabView docs: rename border param to borderStyle

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.

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.

* Refactored a method to draw a label when the location is already known.
(This one takes care of setting up the correct color.)
* Added TODO about using either B_CONTROL_TEXT_COLOR, or elliminating that
constant (which I am in favor of...).

* Added a (to be virtual) DefaultItemSpacing() method to control look. This is
what you should use in for example BGroupLayout as spacing/inset.
* Changed the label spacing to be dependent on the font size, too (and enlarged
it a bit as well).

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.

* Added BSplitView drawing code to ControlLook.
* BSplitView uses ControlLook to draw itself.
* Small refactoring in SplitLayout to implement IsAboveSplitter(BPoint).
* BSplitView updates the view cursor when the mouse is above a splitter.
* Standard splitter size is now 6 pixels, which is a bit easer to hit.

Introduce the possiblity to draw certain frames with alpha blending on top of
an existing background. It's not supported by many frame types yet, but BButton
and TextControl frames work as well as the soft recessed frame which many
controls use.

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.

Moved the BScrollView frame drawing entirely into BControlLook.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29661 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added method to draw an arrow shape like that of the BScrollBar.
TODO: Adjust BScrollBar to use it.
TODO: Make it virtual like the others, but I don't want to break Vision and
other native Haiku apps just now.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29630 a95241bf-73f2-0310-859d-f6bbb57e9c96

Make BMenuBar background drawing more flexible and also support an "activated"
state.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29597 a95241bf-73f2-0310-859d-f6bbb57e9c96

Improved the look of the slider triangle thumb. Still missing is the vertical
version.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29311 a95241bf-73f2-0310-859d-f6bbb57e9c96

Fixed BTabs focus underline offset.
Fixed a typo in method name.

Please forgive me Stephan if I just screw your next commit...

* Stronger BMenuField popup indicator.
* Softer recessed frame for BMenuField to distinguish more from BButton
and make it slightly more similar to BTextControl.

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.
