/**
|
|
* Layout function which sets the box @a o to a (basic) horizontal
|
|
* box. @a priv must be the smart data of the box.
|
|
*
|
|
* The object's overall behavior is controlled by its properties,
|
|
* which are set by the evas_object_box_{h,v}_{align,padding}_set()
|
|
* family of functions. The properties of the elements in the box --
|
|
* set by evas_object_size_hint_{align,padding,weight}_set() functions
|
|
* -- also control the way this function works.
|
|
*
|
|
* \par box's properties:
|
|
* @c align_h controls the horizontal alignment of the child objects
|
|
* relative to the containing box. When set to 0, children are aligned
|
|
* to the left. A value of 1 lets them aligned to the right border.
|
|
* Values in between align them proportionally. Note that if the size
|
|
* required by the children, which is given by their widths and the @c
|
|
* padding_h property of the box, is bigger than the container width,
|
|
* the children will be displayed out of its bounds. A negative value
|
|
* of @c align_h makes the box to *justify* its children. The padding
|
|
* between them, in this case, is corrected so that the leftmost one
|
|
* touches the left border and the rightmost one touches the right
|
|
* border (even if they must overlap). The @c align_v and @c
|
|
* padding_v properties of the box don't contribute to its behaviour
|
|
* when this layout is chosen.
|
|
*
|
|
* \par Child element's properties:
|
|
* @c align_x does not influence the box's behavior. @c padding_l and
|
|
* @c padding_r sum up to the container's horizontal padding between
|
|
* elements. The child's @c padding_t, @c padding_b and @c align_y
|
|
* properties apply for padding/positioning relative to the overall
|
|
* height of the box. Finally, there is the @c weight_x property,
|
|
* which, if set to a non-zero value, tells the container that the
|
|
* child width is not pre-defined. If the container can't accommodate
|
|
* all its children, it sets the widths of the children *with weights*
|
|
* to sizes as small as they can all fit into it. If the size
|
|
* required by the children is less than the available, the box
|
|
* increases its children's (which have weights) widths as to fit the
|
|
* remaining space. The @c weight_x property, besides telling the
|
|
* element is resizable, gives a *weight* for the resizing process.
|
|
* The parent box will try to distribute (or take off) widths
|
|
* accordingly to the *normalized* list of weigths: most weighted
|
|
* children remain/get larger in this process than the the least ones.
|
|
* @c weight_y does not influence the layout.
|
|
*
|
|
* If one desires that, besides having weights, child elements must be
|
|
* resized bounded to a minimum or maximum size, their size hint
|
|
* properties must be set (by the
|
|
* evas_object_size_hint_{min,max}_set() functions.

*
|
|
* In a homogeneous horizontal box, its width is divided equally

|
|
* also control the way this function works.
|
|
*
|
|
* \par box's properties:
|
|
* @c align_h has no influence on the box for this layout. @c
|
|
* padding_h tells the box to draw empty spaces of that size, in
|
|
* pixels, between the (still equal) child objects's cells. The @c

|
|
*
|
|
* \par Child element's properties:
|
|
* @c padding_l and @c padding_r sum up to the required width of the
|
|
* child element. The @c align_x property tells the relative position
|
|
* of this overall child width in its allocated cell (0 to extreme
|
|
* left, 1 to extreme right). A value of -1.0 to @c align_x makes the
|
|
* box try to resize this child element to the exact width of its cell
|
|
* (respecting the min and max hints on the child's width *and*
|
|
* accounting its horizontal padding properties). The child's @c
|
|
* padding_t, @c padding_b and @c align_y properties apply for
|
|
* padding/positioning relative to the overall height of the box. A
|
|
* value of -1.0 to @c align_y makes the box try to resize this child
|

/**
|
|
* Layout function which sets the box @a o to a *flow* horizontal box.
|
|
* @a priv must be the smart data of the box.
|
|
*
|
|
* In a flow horizontal box, the box's child elements are placed in
|
|
* rows (think of text as an analogy). A row has as much elements as
|
|
* can fit into the box's width. The box's overall behavior is
|
|
* controlled by its properties, which are set by the
|
|
* evas_object_box_{h,v}_{align,padding}_set() family of functions.
|
|
* The properties of the elements in the box -- set by
|
|
* evas_object_size_hint_{align,padding,weight}_set() functions --
|
|
* also control the way this function works.
|
|
*
|
|
* \par box's properties:
|
|
* @c padding_h tells the box to draw empty spaces of that size, in
|
|
* pixels, between the child objects's cells. @c align_h dictates the
|
|
* horizontal alignment of the rows (0 to left align them, 1 to right
|
|
* align). A value of -1.0 to @c align_h lets the rows *justified*
|
|
* horizontally. @c align_v controls the vertical alignment of the
|
|
* entire set of rows (0 to top, 1 to bottom). A value of -1.0 to @c
|
|
* align_v makes the box to *justify* the rows vertically. The padding
|
|
* between them, in this case, is corrected so that the first row
|
|
* touches the top border and the last one touches the bottom border
|
|
* (even if they must overlap). @c padding_v has no influence on the
|
|
* layout.
|
|
*
|
|
* \par Child element's properties:
|
|
* @c padding_l and @c padding_r sum up to the required width of the
|
|
* child element. The @c align_x property has no influence on the
|
|
* layout. The child's @c padding_t and @c padding_b sum up to the
|
|
* required height of the child element and is the only means (besides
|
|
* row justifying) of setting space between rows. Note, however, that
|
|
* @c align_y dictates positioning relative to the *largest height*
|
|
* required by a child object in the actual row.
