From 8f1db27b6be1a0154a0bfce7d9882db298f7dc5e Mon Sep 17 00:00:00 2001 From: Christian Hergert Date: Wed, 1 Jun 2022 11:26:44 -0700 Subject: [PATCH] gtkmain: add support for GTK_DEBUG=invert-text-dir This allows inverting the default text-direction in an application for debugging, testing, and QA purposes. IDEs such as Builder may automate this to encourage more application developers to test with a text-direction different than their own. --- gtk/gtkdebug.h | 1 + gtk/gtkmain.c | 13 ++++++++++++- 2 files changed, 13 insertions(+), 1 deletion(-) diff --git a/gtk/gtkdebug.h b/gtk/gtkdebug.h index f1cad3ea59..a5b8eff2d1 100644 --- a/gtk/gtkdebug.h +++ b/gtk/gtkdebug.h @@ -82,6 +82,7 @@ typedef enum { GTK_DEBUG_BUILDER_OBJECTS = 1 << 16, GTK_DEBUG_A11Y = 1 << 17, GTK_DEBUG_ICONFALLBACK = 1 << 18, + GTK_DEBUG_INVERT_TEXT_DIR = 1 << 19, } GtkDebugFlags; #ifdef G_ENABLE_DEBUG diff --git a/gtk/gtkmain.c b/gtk/gtkmain.c index 7cc39c35f8..80c7542b03 100644 --- a/gtk/gtkmain.c +++ b/gtk/gtkmain.c @@ -203,6 +203,7 @@ static const GdkDebugKey gtk_debug_keys[] = { { "snapshot", GTK_DEBUG_SNAPSHOT, "Generate debug render nodes" }, { "accessibility", GTK_DEBUG_A11Y, "Information about accessibility state changes" }, { "iconfallback", GTK_DEBUG_ICONFALLBACK, "Information about icon fallback" }, + { "invert-text-dir", GTK_DEBUG_INVERT_TEXT_DIR, "Invert the default text direction" }, }; /* This checks to see if the process is running suid or sgid @@ -523,6 +524,7 @@ static void do_post_parse_initialization (void) { GdkDisplayManager *display_manager; + GtkTextDirection text_dir; gint64 before G_GNUC_UNUSED; if (gtk_initialized) @@ -536,7 +538,16 @@ do_post_parse_initialization (void) signal (SIGPIPE, SIG_IGN); #endif - gtk_widget_set_default_direction (gtk_get_locale_direction ()); + text_dir = gtk_get_locale_direction (); + + /* We always allow inverting the text direction, even in + * production builds, as SDK/IDE tooling may provide the + * ability for developers to test rtl/ltr inverted. + */ + if (gtk_get_debug_flags () & GTK_DEBUG_INVERT_TEXT_DIR) + text_dir = (text_dir == GTK_TEXT_DIR_LTR) ?
