I’ve created an action_bar widget with 3 children, a label and 2 buttons. I’ve tried multiple width and height dimensions in the gtk_widget_set_size_request() method. No matter the dimensions I put the action bar ALWAYS is the same height no matter the size of the window itself.

This is my code I have for the entire project. I’m sorry that all the code is squished together. I had some copy and pasting issues…

#include <gtk/gtk.h>
#include <pango/pango.h>
#include <stdio.h>
//READERS! This code is meant to be easily read for people who want to learn!
//Handles initializing the window
static void activateWindow(GtkApplication *app) {
        GtkWidget *window = gtk_application_window_new(app);
        //TopActionBar | Creation
        GtkWidget *topActionBar = gtk_action_bar_new();
        //This line is the issue.
        gtk_widget_set_size_request(GTK_WIDGET(topActionBar), -1, 17);
        //TopActionBar | TITLE
                GtkWidget *bideLabel = gtk_label_new(NULL);
                gchar *bideLabelText = g_markup_printf_escaped("<b>BIDE</b>");
                gtk_label_set_markup(GTK_LABEL(bideLabel), bideLabelText);
                gtk_action_bar_pack_start(GTK_ACTION_BAR(topActionBar), GTK_WIDGET(bideLabel));
                //TopActionBar | Open Folder Button
                GtkWidget *openFolder = gtk_button_new();
                gtk_button_set_label(GTK_BUTTON(openFolder), "Open Folder");
                gtk_action_bar_pack_start(GTK_ACTION_BAR(topActionBar), GTK_WIDGET(openFolder));
                //TopActionBar | Help Menu Button
                gchar *helpButtonText = g_markup_printf_escaped("<u>HELP</u>");
                GtkWidget *helpButton = gtk_button_new();
                GtkWidget *helpLabel = gtk_label_new("Help");
                gtk_label_set_markup(GTK_LABEL(helpLabel), helpButtonText);
                gtk_button_set_child(GTK_BUTTON(helpButton), GTK_WIDGET(helpLabel));
                gtk_action_bar_pack_start(GTK_ACTION_BAR(topActionBar), GTK_WIDGET(helpButton));
        gtk_window_set_child(GTK_WINDOW(window), GTK_WIDGET(topActionBar));
        gtk_window_present(GTK_WINDOW(window));

}
int main(int argc, char *argv[]){
        GtkApplication *app = gtk_application_new("me.lufthor.bide", G_APPLICATION_DEFAULT_FLAGS);
        g_signal_connect(app, "activate", G_CALLBACK(activateWindow), NULL);
        return g_application_run(G_APPLICATION(app), argc, argv);

}

I tried messing around with the height and width values and NOTHING. Nothing changed.
