This function creates a new icon button widget.
It allocates required memory and initializes necessary windows to create the widget. If there is not enough memory, the function returns NULL. To destroy the widget and all its contents, and free its memory, call win_destroy() on the icon button's child reference, given by wtk_icon_button_as_child(), like this: "win_destroy(wtk_icon_button_as_child(myButtonPtr));". Usually it will be destroyed automatically when it's parent is destroyed.
| parent | Parent window, possibly wtk_frame_as_parent(myFramePtr). |
| area | Area of the internal contents. |
| icon | Bitmap to draw as the icon. |
| selected | Initial state of icon button, true if checked/selected. |
| group | Icon button group to be a member of. |
| command | Command to send to parent window. Must be non-zero to be enabled. |

| void wtk_icon_button_select | ( | struct wtk_icon_button * | icon_button | ) |
This function sets this icon button to be the single icon button selected within its group.
If another icon button was selected, it will be deselected. Both widgets will be redrawn if visible.

| struct wtk_icon_group* wtk_icon_group_create | ( | void | ) |
This function creates a new icon button group, allocating required memory and properly initializing the object.
If there is not enough memory, the function returns NULL. The icon button group will keep a reference count for its members, and will be automatically destroyed when the last member is destroyed.
