From aab10ea43ba657a5d3923df59821d156a9b0e4cb Mon Sep 17 00:00:00 2001 From: Emmanuele Bassi Date: Thu, 6 Feb 2020 15:43:55 +0000 Subject: [PATCH] Add GtkShortcutManager This adds an interface for taking care of shortcut controllers with managed scope. Only GtkWindow currently implements this interface, so we need to ensure that we check if any top-level widget we reach is a shortcuts manager before we call into it. --- docs/reference/gtk/gtk4-docs.xml | 1 + docs/reference/gtk/gtk4-sections.txt | 16 +++++++ docs/reference/gtk/gtk4.types.in | 1 + gtk/gtk.h | 1 + gtk/gtkroot.c | 2 + gtk/gtkshortcutcontroller.c | 71 ++++++++++++++++++++-------- gtk/gtkshortcutmanager.c | 70 +++++++++++++++++++++++++++ gtk/gtkshortcutmanager.h | 71 ++++++++++++++++++++++++++++ gtk/gtkwidget.c | 6 ++- gtk/gtkwindow.c | 9 ++++ gtk/meson.build | 2 + 11 files changed, 228 insertions(+), 22 deletions(-) create mode 100644 gtk/gtkshortcutmanager.c create mode 100644 gtk/gtkshortcutmanager.h diff --git a/docs/reference/gtk/gtk4-docs.xml b/docs/reference/gtk/gtk4-docs.xml index 73f3effe67..952019a2b8 100644 --- a/docs/reference/gtk/gtk4-docs.xml +++ b/docs/reference/gtk/gtk4-docs.xml @@ -343,6 +343,7 @@ Keyboard shortcuts + diff --git a/docs/reference/gtk/gtk4-sections.txt b/docs/reference/gtk/gtk4-sections.txt index 534653d922..20a81805f3 100644 --- a/docs/reference/gtk/gtk4-sections.txt +++ b/docs/reference/gtk/gtk4-sections.txt @@ -6097,12 +6097,21 @@ GTK_SHORTCUT_GET_CLASS gtk_shortcut_get_type +
