This patch adds a method to nsLayoutUtils, alongside the existing
HasCurrentAnimations, that returns true if there exists an unfinished animation
on the element for the specified property.
According to roc the content viewer position doesn't mean much; only the size is
set to anything meaningful. Therefore using the position from the content viewer
bounds is not a good idea, and we should use the position from the frame bounds
instead. This patch also changes GetContentViewerBounds to GetContentViewerSize
so that it's harder to accidentally use the position in other places.
This patch started an attempt to remove nsFrameSelection.h from nsCaret.h
and metastasized into a rather large refactoring patch that removed it
from some other header files as well, and changed nsFrameSelection::HINT
into a global-scope enum with better names. I also converted bools
into CaretAssociationHint in a few places where that was appropriate,
but there are still some more places (GetChildFrameContainingOffset)
where bools need to be converted. I figured this patch was big enough already.
To account for spacing between bases or text boxes during reflow, the line
layout which manages the bases updates its inline direction coordinate based on
the preferred inline size for the corresponding text boxes. Next, the base is
reflowed at the correct inline coordinate. Each paired text box is then also
reflowed at the proper inline position determined by (1) the current position of
its corresponding base and (2) its own preferred width.
In computing intrinsic widths, accounting for spacing is less complicated. The
minimum intrinsic width is the width of the widest ruby column, and the
preferred intrinsic width is the sum of all the ruby column widths. Each ruby
column width is the maximum width of its base box and text boxes. These
individual widths are determined using GetPrefISize on the base and text boxes.
Ruby base container frames store a list of pointers to the ruby text container
frames in the segment they denote. This list of pointers is created in the ruby
frame reflow method before calling the reflow method for the ruby base
container. The list exists and is used only during reflow of the main ruby frame
and is cleared before returning from reflow.
As the third step in dividing functionality between AnimationPlayer and
Animation this patch moves the mIsFinishedTransition member and related methods
from AnimationPlayer to Animation.
At the same time we rename SetFinishedTransition to SetIsFinishedTransition.
As the first step in dividing the functionality currently contained in
AnimationPlayer between AnimationPlayer and Animation this patch moves the set
of keyframe properties to the Animation.
These properties are returned from the Animation by a couple of Properties()
methods that provide direct access to the member variable. In future it is
anticipated that the non-const version will be replaced with an appropriate
setter function. This will likely happen when we implement a separate
KeyframeEffect object as defined by the Web Animations API.
With regards to error checking, nsAnimationManager checks the result of
AnimationPlayer::GetSource() and handles the case where it is nullptr.
nsTransitionManager, however, simply asserts that GetSource() is never null much
like it also asserts that there is only one property with one segment in the
animation. Eventually this code should be made more generic which will probably
happen in bug 999927.
Now that we have both AnimationPlayer and Animation in use we need to clarify
which object we are referring to. This patch renames a number of member and
local variables to better reflect whether they point to an AnimationPlayer or an
Animation.
This patch is mostly renaming only with one exception. Since we are touching
a number of local variables used in loops (for looping over the array of
animation players) we take the opportunity to replace a number of instances of
uint32_t with size_t since that is the preferred type for array indices now.
This patch renames mozilla::ElementAnimations to mozilla::dom::AnimationPlayer
and moves the code from layout/style/AnimationCommon.cpp to
dom/animation/AnimationPlayer.cpp.
It also moves various helper classes needed by AnimationPlayer to
AnimationPlayer.cpp and moves them from the mozilla::css namespace to the
mozilla namespace.
Beyond that, there are no functional changes contained in this patch.
The renaming of various members and variables that used to refer to
ElementAnimation objects but now refer to AnimationPlayer objects--to give them
a more appropriate name--is performed in a subsequent patch.
