void hime_view_set_preferred_size(self, size)
Sets or unsets the size that this View will request during layout.
Parameters
hime_view_t
selfhime_size_t*
size
Return
void
hime_size_t hime_view_get_preferred_size(self)

Parameters
hime_view_t
self
Return
hime_size_t
void hime_view_set_style(self, name, value)
Change the styles of the view.
Note that calling this method does not changes the bounds immediately,
the bounds will change when the view hierarchy re-calculates the layout,
such as when resizing window or when adding/removing child views. To make
the new styles apply immediately you can call Layout
method.
Parameters
hime_view_t
selfconst char16_t*
nameconst char16_t*
value
Return
void
void hime_view_set_style_number(self, name, value)
Change the styles of the view.
Note that calling this method does not changes the bounds immediately,
the bounds will change when the view hierarchy re-calculates the layout,
such as when resizing window or when adding/removing child views. To make
the new styles apply immediately you can call Layout
method.
Parameters
hime_view_t
selfconst char16_t*
namefloat
value
Return
void
void hime_view_layout(self)
Re-calculate the layout in view hierarchy.
Parameters
hime_view_t
self
Return
void
void hime_view_set_background(self, background)
Set the background
of the view.
Parameters
hime_view_t
selfhime_background_t
background
Return
void
void hime_view_set_border(self, border)
Set the border
of the view.
Note that it is also possible to set border via the SetStyle
API, but
it only serves as layout property rather than actually drawin a border,
while the SetBorder
API actually draws the border.
The two types of borders do not know each other and setting both might cause weird visual effects, this will change in future and please be prepared for it.
Parameters
hime_view_t
selfhime_border_t
border
Return
void
void hime_view_add_child_view(self, view)
Append a child view

to this view at index
.
Parameters
hime_view_t
selfhime_view_t

index
Return
void
void hime_view_remove_child_view(self, view)
Remove a child view
from this view.
Parameters
hime_view_t
selfhime_view_t
view
Return
void
size_t hime_view_child_count(self)
Return the count of children in this view.
Parameters
hime_view_t
self
Return
size_t
hime_view_t hime_view_child_at(self, index)

.
Parameters
hime_view_t
selfsize_t
index

void hime_view_set_accessible_name(self, name)
Set the accessible name.
The value of the accessible name is a localized, end-user-consumable string which may be derived from visible information (e.g. the text on a button) or invisible information (e.g. the alternative text describing an icon). In the case of focusable objects, the name will be presented by the screen reader when that object gains focus and is critical to understanding the purpose of that object non-visually.
Parameters
hime_view_t
selfconst char16_t*
name
Return
void
const char16_t* hime_view_get_accessible_name(self)
Get the accessible name.
Parameters
hime_view_t
self
Return
const char16_t*
void hime_view_set_group(self, group)
Set the group
id of this view.
Some view subclasses use this id to find other views of the same group. For example radio button uses this information to find other radio buttons.
Parameters
hime_view_t
selfint
group
Return
void
void hime_view_get_group(self)
Get the group id of this view.
Parameters
