A container made to have a search entry
|
|
(possibly with additional widgets,
|
|
such as drop-down menus, or buttons)
|
|
built-in.
|
|
|
|
The search bar would appear when a search
|
|
is started through typing on the keyboard,
|
|
or the application's search mode is toggled on.
|
|
|
|
For keyboard presses to start a search,
|
|
events will need to be forwarded from the
|
|
top-level window that contains the search bar.
|
|
See gtk_search_bar_handle_event() for example code.
|
|
Common shortcuts such as Ctrl+F should be handled
|
|
as an application action, or through the menu items.
|
|

|
Type a word which appears in the text above, or hit the esc key
|
|
to clear.
