This function returns the identifier of the created button, or nil if an error occurs.

Notes

Buttons with images or texts can not change its behavior after mapped. This is a creation attribute. But after creation the image can be changed for another image, and the text for another text.

Text and images are always centered.

Buttons are activated using Enter or Space keys.

When IMPRESS and IMAGE are defined together, IUP does not show the element's border to provide a 3D effect; the user has to define the border in the image itself.

In Windows, when using Windows XP Visual Styles the BGCOLOR attribute is ignored when a non empty text button is created.
