How do I put a GTKScrolledWindow inside of another container?

Question

I want to have a scrollable GtkTextView in my GtkWindow, but I only want the GtkTextView part to scroll instead of the whole window. I tried to put the GTKTextView inside of a GtkScrolledWindow and put the GtkScrolledWindow inside of a GtkFixed container, but then the GtkTextView doesn't show up. When I put the GtkTextView directly inside the GtkFixed container, though, it shows up.

#include <gtk/gtk.h>

GtkWidget *window, *scrolled_window, *fixed, *log_box, *button1;
GtkTextBuffer *log_box_buffer;

static void button1_clicked(GtkWidget *widget, gpointer data) {
    printf("button1_clicked\n");
    gtk_text_buffer_insert_at_cursor(log_box_buffer, "You clicked the button.\n", 24);
}

static void app_activate(GtkApplication *app, gpointer user_data) {

    window = gtk_application_window_new(app);
    gtk_window_set_title(GTK_WINDOW(window), "Window Title Here");
    gtk_window_set_default_size(GTK_WINDOW(window), 700, 400);
    gtk_window_set_position(GTK_WINDOW(window), GTK_WIN_POS_CENTER);

    scrolled_window = gtk_scrolled_window_new(NULL, NULL);

    fixed = gtk_fixed_new();

    button1 = gtk_button_new_with_label("Button 1");
    g_signal_connect(button1, "clicked", G_CALLBACK(button1_clicked), NULL);

    log_box_buffer = gtk_text_buffer_new(NULL);
    log_box = gtk_text_view_new_with_buffer(log_box_buffer);

    gtk_fixed_put(GTK_FIXED(fixed), button1, 50, 50);


    /* Here I tried to put the textview inside of the scrolled window and
       add the scrolled window to the fixed container. The textview
       doesn't show up when I do this. */

    gtk_container_add(GTK_CONTAINER(scrolled_window), log_box);
    gtk_fixed_put(GTK_FIXED(fixed), scrolled_window, 200, 50);


    /* I also tried putting the textview directly in the fixed container.
       This shows up, but obviously I can't scroll it. */

//  gtk_fixed_put(GTK_FIXED(fixed), log_box, 200, 50);


    gtk_container_add(GTK_CONTAINER(window), fixed);
    gtk_widget_show_all(window);
}

int main(int argc, char **argv) {

    GtkApplication *app;
    int status;

    app = gtk_application_new("the.application.id", G_APPLICATION_FLAGS_NONE);
    g_signal_connect(app, "activate", G_CALLBACK(app_activate), NULL);

    status = g_application_run(G_APPLICATION(app), argc, argv);

    g_object_unref(app);
    return status;
}

not sure why you want to use a fixed container. If so you must supply the width and height of the scrolled window, which contains the textview. I've compiled your code and it works. Just add:

gtk_widget_set_size_request (GTK_WIDGET(scrolled_window), 200, 200);

and this will set a size of 200 by 200, as an example, on your scrolled window.

I'm using the fixed container because I'm going to other stuff in the window that shouldn't scroll. This worked after a slight edit, by the way. I had to use the `GTK_WIDGET` macro instead of the `GTK_WINDOW` macro. Can you please update your answer? – Jason May 28 '17 at 11:06

Yes sorry i meant GTK_WIDGET not GTK_WINDOW but i retyped instead of just a copy paste... Was just a line... And i mistake it :/ thanks. – José Fonte May 28 '17 at 11:22

@Jason Gtk fixed is very specific maybe using layout containers would be a better fit so that the layout adjusts to window resizing, etc – José Fonte May 28 '17 at 11:26

Thanks for the advice. This is my first GTK app, so I'm still experimenting. I will try out different layout containers soon. – Jason May 28 '17 at 11:28
