onClosePage
Emitted after [method@TabView.close_page] has been called for @page.
The handler is expected to call [method@TabView.close_page_finish] to
confirm or reject the closing.
The default handler will immediately confirm closing for non-pinned pages,
or reject it for pinned pages, equivalent to the following example:
```c
static gboolean
close_page_cb (AdwTabView *view,
AdwTabPage *page,
gpointer user_data)
{
adw_tab_view_close_page_finish (view, page, !adw_tab_page_get_pinned (page));
return GDK_EVENT_STOP;
}
```
The [method@TabView.close_page_finish] call doesn't have to happen inside
the handler, so can be used to do asynchronous checks before confirming the
closing.
A typical reason to connect to this signal is to show a confirmation dialog
for closing a tab.
The signal handler should return `GDK_EVENT_STOP` to stop propagation or
`GDK_EVENT_CONTINUE` to invoke the default handler.- Parameter:
page- a page of @self- Gibt zurück:
- whether propagation should be stopped
