### Arguments

- *int* **size** - The size of the second child

## int getSecondSize () const

Returns the current size of the second child.
### Return value

Current size of the second child
## void setFirstSize ( int size )

Sets a new size of the first child.
### Arguments

- *int* **size** - The size of the first child

## int getFirstSize () const

Returns the current size of the first child.
### Return value

Current size of the first child
## void setFixed ( int fixed )

Sets a new number of the child with the fixed size:
- 0 - size of both children is not fixed.
- 1 - size of the first child is fixed.
- 2 - size of the second child is fixed.


### Arguments

Other values specify proportions, in which the children are resized.
### Arguments

- *int* **value** - The value specifying how the child widgets are resized

## int getValue () const

Returns the current value specifying how the child widgets are resized, in range **[-32767; 32767]**. **-32767** means that during resize the upper child will remain fixed. **32767** means that during resize the lower child will remain fixed. **0** means that both children will be resized equally.
