BeOS had a feature where you could click on a list and while holding
down the mouse button scroll through the list items selecting them
as you went. I implemented the same feature on Haiku.
Did the work in separate thread which makes sure that the mouse
is held down the whole time even if you leave the view.
Thanks Diver for bringing this feature to my attention.
* Rename kDoubleClickTresh to kDoubleClickThreshold
and use floating point in rval
* Pointer (*) goes with type for property var
* Use {}'s for multi-line if conditional
* rename point to where (consistent with header and rest of IK)
* Explicitly compare with 0 for bitwise operator statements
* Rename InitiateDrag() params
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.

* 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.

BListView. This fixes bug #3919. Got rid of the _TryInitiateDrag() method,
and let MouseMoved() do it all.
* Style cleanup of the header, automatic whitespace cleanup.

broke everything. If the added item has no chance to calculate it's height,
_RecalcItemTops() won't work of course. Whatever this was supposed to fix,
there has to be a correct way.
* Override BView::SetFont() to update all the items. I remember wanting to
implement this, that's why I refactored a _FontChanged() method, but I
obviousy never did...
* Moved the AttachedToWindow() and FrameMoved() implementations to a more
logical position in the file.
* Implement B_PAGE_UP/DOWN key presses. Don't know if that's what the BeOS
implementation did, will check later.

if the items were the same height.
- Modified _RecalcItemTops to allow us to specify a range instead of
just a starting point. This is useful for cases like Swap, where
only the items in between those being swapped need to be
recalculated.

* BListItems now store the top offset of the frame within the parent BListView.
* This allows binary searching the clicked item.
* ItemFrame() is now a cheap call.
* Fixed several bugs in the sorting code of BOutlineListView which lead to
crashes of client applications.
* Implemented previously unimplemented functions in BOutlineListView.

only invokes the BView version. Didn't know what to do with MinSize() and
PreferredSize(). ATM they return fixed, hard-coded values. It might make
sense to compute something depending on the font size, for instance.

* removed weird stuff that seemed to have no purpose in life
* added more comments where I had to figure things out
* fWidth is now adjusted in FrameResized()
* ListView scrolls up when items are removed at the end and
there would be empty room
* fixed SwapItems(), MoveItem() and ReplaceItem() by making
DoMiscellaneous() use the private implementations instead
of calling the public ones again resulting in an endless
loop
* renamed private methods with underscore
* removed more unused/empty private methods
* some slight performance increases here and there
* more correct tracking of fFirstSelected and fLastSelected,
at least I cannot reproduce one crash in the WonderBrush
Layer list anymore
even more cleanup and testing would not hurt though...
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17487 a95241bf-73f2-0310-859d-f6bbb57e9c96
* fix deselecting items
* fix selection with the mouse and also holding down modifiers
* fix some more stuff I have already forgotten
* applied coding style in most places
* renamed private functions to be consistent
needs more work though, some stuff can definitely be
removed, some needs to be added
