Add accessors for range->range_rect, range->slider_range,
range->slider_size_fixed and range->min_slider_size. Didn't add
properties for any of them because thir purpose is mostly to enable
proper subclassing.
This is exposed by overshooting in a HildonPannableArea. Leaking
a GtkTreeRowReference also means leaking the whole model, since
the GtkTreeModel reference count is increased for each row
reference.
Fixes bug #607770 - Leak in GtkTreeView with HildonPannableArea
If e.g. the right edge of the leftmost rectangle is near MIN_INT, and
the left edge of the rightmost rectangle is large then subtracting these
can lead to an integer overflow, making the resultant "width" falsely
positive, thus returning a very wide result instead of the expected
no-intersection result.
We avoid the overflow by not doing the subtraction unless we know the
result will be positive. There are still risks for overflow if x + width
or y + width is larger than MAXINT, but we won't ever overflow for valid
rects now.
This may fix#607687
We need to do this because otherwise the implicit button grab for this
(native) window will not deliver the button events not selected for
by this window. This is a problem because non-native child windows may
select using a wider event mask, and we can't emulate these events if we
don't get the native events.
Fixes bug #607508
When a cairo surface is requested for direct window access (i.e. not
when double-buffering) we can't really track when the actual drawing happens
as cairo drawing is not virtualized. This means we can't properly flush
any outstanding window moves or implicit paints.
This actually causes problems with e.g. abiword (bug #606009) where they
draw without double-buffering. If you press down it scrolls the window
and then draws the caret, but the caret drawing does not flush the
outstanding move from the scroll, so the caret gets drawn on the wrong
screen.
We fix this by never allowing either implicit paints or outstanding window
moves on impl-windows where any windows related to it has an outstanding
direct cairo surface. Luckily this is not very common so in practice this
doesn't matter much.
* gtk/gtktoolpalette.[h|cc]: gtk_tool_palette_get_drop_group():
Change the return type from GtkWidget* to GtkToolItemGroup*,
for consistency with other parts of GTK+, such as GtkToolbar.
It may happen that a window gets destroyed during painting, if so
we should not draw the implicit paint double-buffered pixmap to it
as that will cause a BadDrawable X error.
This fixes bug 600865
