|
|
|
* GtkHeaderBar is similar to a horizontal #GtkBox. It allows children to
|
|
|
|
* be placed at the start or the end. In addition, it allows a title and
|
2013-12-22 02:58:24 +00:00
|
|
|
* subtitle to be displayed. The title will be centered with respect to
|
|
|
|
* the width of the box, even if the children at either side take up
|
|
|
|
* different amounts of space. The height of the titlebar will be
|
|
|
|
* set to provide sufficient space for the subtitle, even if none is
|
|
|
|
* currently set. If a subtitle is not needed, the space reservation
|
|
|
|
* can be turned off with gtk_header_bar_set_has_subtitle().
|
|
|
|
*
|
|
|
|
* GtkHeaderBar can add typical window frame controls, such as minimize,
|
|
|
|
* maximize and close buttons, or the window icon.
