font-size-combo-box

A subclass of combo-box, used for changing the font height of an associated rich-edit control. This control's range is always a standard list of typical font sizes, though any size may be typed in. When the end user selects a font face (see font-face-combo-box), the selected text in the associated rich-edit control is changed to the selected font height. The control's value will also update automatically to display the font size of the text that is currently selected in the associated rich-edit control.

If there are any rich-edit controls on the same parent window as the font-size-combo-box, and at least one of them has had the keyboard focus, then the combo-box will affect the rich-edit that most recently had (or still has) the focus; otherwise it will do nothing. If a rich-edit is not found on the same parent window, then the grandparent window is searched, followed by the great-grandparent and so on; this allows a font-size-combo-box to be placed on the toolbar of a dialog that contains a rich-edit control in its main area, for example.
