Partially revert commit c73710e410,
avoiding updating tool widgets unconditionally on tool resume in
GimpDrawTool -- it's too expensive in general.
Instead, handle display-shell changes in GimpToolWidget, by adding
GimpToolWidget::update_on_{scale,scroll,rotate} flags, which
subclasses can use to request an update on any of these events.
Set the flags as necessary for the affected widgets.
Add a boolean GimpTransformGridTool::dynamic-handle-size property,
which controls whether the handle sizes are adjustment dynamically
according to the grid's size, or remain fixed. This property is
TRUE by default, to maintain the current behavior.
In GimpToolTransformGrid, allow setting "inside-function" and
"outside-function" to a new NONE value, performing no
transformation when dragging the respective area.
In GimpTransformGridTool, avoid producing non-finite coordinate
and angle values. In particular, this fixes a crash in
gimp_transform_grid_tool_get_cursor() as a result of a NaN angle
value being converted to a negative integer, hitting an assert.
In GimpToolTransformGrid, use the transformed center-point of the
original polygon as the position of the center-point handle, and as
a snapping point for the pivot when "cornersnap" is TRUE, instead
of using the center-point of the transformed polygon. These two
points are different for non-affine transformations.
Furthermore, when "use-pivot-handle" is FALSE, use the center-
point as the reference point when transforming around the pivot,
instead of the pivot itself, which might not be set. In
particular, this fixes transformation around the pivot in the
perspective tool.
Don't explicitly set the center-point as the pivot in the scale
tool, since this commit makes it unnecessary.
... and G_TYPE_INSTANCE_GET_PRIVATE()
g_type_class_add_private() and G_TYPE_INSTANCE_GET_PRIVATE() were
deprecated in GLib 2.58. Instead, use
G_DEFINE_[ABSTRACT_]TYPE_WITH_PRIVATE(), and
G_ADD_PRIVATE[_DYNAMIC](), and the implictly-defined
foo_get_instance_private() functions, all of which are available in
the GLib versions we depend on.
This commit only covers types registered using one of the
G_DEFINE_FOO() macros (i.e., most types), but not types with a
custom registration function, of which we still have a few -- GLib
currently only provides a (non-deprecated) public API for adding a
private struct using the G_DEFINE_FOO() macros.
Note that this commit was 99% auto-generated (because I'm not
*that* crazy :), so if there are any style mismatches... we'll have
to live with them for now.
which is just a #define to g_assert for now, but can now easily be
turned into something that does some nicer debugging using our new
stack trace infrastructure. This commit also reverts all constructed()
functions to use assert again.
This avoids warnings when the handle positions the handle-transform
tool result in a matrix that transforms the TransformGrid's handles
(which are all invisible) to coordinates that are outside of the
corresponding properties' range.
Add a "clip" property to GimpCavnasTransformGuides. When set, use
gimp_transform_polygon() for transforming the guides and the
bounding box, so that they're properly clipped.
Add a corresponding "clip-guides" property to
GimpToolTransformGrid, and set it to TRUE in GimpToolHandleGrid, so
that the handle-transform tool's guides are clipped properly.
... which can be used to control the guides' visibility.
Will be used by the next commit, to hide the guides in
GimpToolHandleGrid when the tranformation is invalid.
Change gimp_tool_set_active_modifier_state() to honor the new
GimpToolControlSetting. Explicitly set the mode to SEPARATE in
all tools that require modifier keys during a stroke.
And here comes the actual fix: change GimpTransformTool and
GimpToolTransformGrid to use SAME mode, and remove their
active_modifer_key() and hover_modifier() impls, so it makes no
difference whether a modifier is pressed before of after mouse button
press/release.
and update the grid as soon as a constraint is changed, not only on
the next motion. Change GimpTransformTool to forward the events to the
widget if it exists, but still handle them if it doesn't (yes this
code duplication is ugly, but the widget can hardly handle events if
it doesn't exist...).
Rename gimp_tool_widget_snap_offsets() to set_snap_offsets(),
and add gimp_tool_widget_get_snap_offsets().
Also rename gimp_tool_widget_status() to set_status(), and
add new function and signal set_status_coords().
Simply use g_object_bind_property() to connect the grid properties of
GimpTransformOoptions and GimpToolTransformGrid and remove all other
grid property setting code.
