Hints for an object's weight.

This is a hint on how a container object should resize a given child within its area. Containers may adhere to the simpler logic of just expanding the child object's dimensions to fit its own (see the Efl.Gfx.Hint_Expand helper weight macro) or the complete one of taking each child's weight hint as real weights to how much of its size to allocate for them in each axis. A container is supposed to, after normalizing the weights of its children (with weight hints), distribut the space it has to layout them by those factors -- most weighted children get larger in this process than the least ones.

Accepted values are zero or positive values. Some containers might use this hint as a boolean, but some others might consider it as a proportion, see documentation of each container.

Default weight hint values are 0.0, for both axis.

Since 1.22


  • x - Non-negative double value to use as horizontal weight hint.
  • y - Non-negative double value to use as vertical weight hint.

Overridden from Efl.Gfx.Hint.hint_weight (get, set).
