# TextView 위젯

"enter" 키를 누르면 줄이 바뀝니다.

"enter" 키를 더 누르면 기본 크기 창 안에 줄이 더 생기며, 창 크기를 넘으면서 수직 스크롤 표시줄이 나타납니다.

긴 문장을 적어넣으면 문장에 있는 단어 사이에서 줄바꿈이 일어납니다.

기이이이이이이이이이이이이이이이이이이인 단어가 있다면(길었다면), 수평 스크롤 표시줄이 나타납니다.

Gtk.TextView 예제입니다

#include <gtk/gtk.h>

static void activate (GtkApplication *app, gpointer user_data) { /* Declare variables */ GtkWidget *window; GtkWidget *text_view; GtkWidget *scrolled_window;

GtkTextBuffer *buffer;

/* Create a window with a title, and a default size */ window = gtk_application_window_new (app); gtk_window_set_title (GTK_WINDOW (window), "TextView Example"); gtk_window_set_default_size (GTK_WINDOW (window), 220, 200);

/* The text buffer represents the text being edited */ buffer = gtk_text_buffer_new (NULL);

/* Text view is a widget in which can display the text buffer. * The line wrapping is set to break lines in between words. */ text_view = gtk_text_view_new_with_buffer (buffer); gtk_text_view_set_wrap_mode (GTK_TEXT_VIEW (text_view), GTK_WRAP_WORD);

/* Create the scrolled window. Usually NULL is passed for both parameters so * that it creates the horizontal/vertical adjustments automatically. Setting * the scrollbar policy to automatic allows the scrollbars to only show up * when needed. */ scrolled_window = gtk_scrolled_window_new (NULL, NULL); gtk_scrolled_window_set_policy (GTK_SCROLLED_WINDOW (scrolled_window), GTK_POLICY_AUTOMATIC, GTK_POLICY_AUTOMATIC); /* The function directly below is used to add children to the scrolled window * with scrolling capabilities (e.g text_view), otherwise, * gtk_scrolled_window_add_with_viewport() would have been used */ gtk_container_add (GTK_CONTAINER (scrolled_window), text_view); gtk_container_set_border_width (GTK_CONTAINER (scrolled_window), 5);

gtk_container_add (GTK_CONTAINER (window), scrolled_window);

gtk_widget_show_all (window); }

int main (int argc, char **argv) { GtkApplication *app; int status;

app = gtk_application_new ("org.gtk.example", G_APPLICATION_FLAGS_NONE); g_signal_connect (app, "activate", G_CALLBACK (activate), NULL); status = g_application_run (G_APPLICATION (app), argc, argv); g_object_unref (app);

return status; }
