From 585757d6e6acd7c8dd15073d849278498066dac1 Mon Sep 17 00:00:00 2001 From: Dorota Czaplejewicz Date: Thu, 23 Aug 2018 11:39:49 +0200 Subject: rootston: add support for text input and the basic of input method The compositor acts as a relay between applications using the text-input protocol and input methods using the input-method protocol. This change implements the basic but useful support for input-method, leaving out grabs as well as popups. --- include/rootston/desktop.h | 4 +++ include/rootston/seat.h | 3 +++ include/rootston/text_input.h | 63 +++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 70 insertions(+) create mode 100644 include/rootston/text_input.h (limited to 'include/rootston') diff --git a/include/rootston/desktop.h b/include/rootston/desktop.h index 90851a17..f855e4d5 100644 --- a/include/rootston/desktop.h +++ b/include/rootston/desktop.h @@ -9,6 +9,7 @@ #include #include #include +#include #include #include #include @@ -16,6 +17,7 @@ #include #include #include +#include #include #include #include @@ -53,6 +55,8 @@ struct roots_desktop { struct wlr_idle_inhibit_manager_v1 *idle_inhibit; struct wlr_input_inhibit_manager *input_inhibit; struct wlr_layer_shell_v1 *layer_shell; + struct wlr_input_method_manager_v2 *input_method; + struct wlr_text_input_manager_v3 *text_input; struct wlr_virtual_keyboard_manager_v1 *virtual_keyboard; struct wlr_screencopy_manager_v1 *screencopy; struct wlr_tablet_manager_v2 *tablet_v2; diff --git a/include/rootston/seat.h b/include/rootston/seat.h index 7e7ee3e9..0187c6cc 100644 --- a/include/rootston/seat.h +++ b/include/rootston/seat.h @@ -5,6 +5,7 @@ #include "rootston/input.h" #include "rootston/keyboard.h" #include "rootston/layers.h" +#include "rootston/text_input.h" struct roots_seat { struct roots_input *input; @@ -19,6 +20,8 @@ struct roots_seat { // If the focused layer is set, views cannot receive keyboard focus struct wlr_layer_surface_v1 *focused_layer; + struct roots_input_method_relay im_relay; + // If non-null, only this client can receive input events struct wl_client *exclusive_client; diff --git a/include/rootston/text_input.h b/include/rootston/text_input.h new file mode 100644 index 00000000..82e45e3e --- /dev/null +++ b/include/rootston/text_input.h @@ -0,0 +1,63 @@ +#ifndef ROOTSTON_TEXT_INPUT_H +#define ROOTSTON_TEXT_INPUT_H + +#include +#include +#include +#include "rootston/seat.h" + +/** + * The relay structure manages the relationship between text-input and + * input_method interfaces on a given seat.
