Gtk_link_button_new_with_label does not set the Label

[MichiB (Michael Buzgaru)]

I am not sure if this is the best Title, but I will try to explain.

I am creating a LinkButton with the following:

gtk_link_button_new_with_label ( "Gnome", "https://www.discourse.gnome.org/" );

And the Label “Gnome” does not get set on the LinkButton.

It has the same effect as I create the LinkButton with:

gtk_link_button_new ( "https://www.discourse.gnome.org/" );

The only difference is that, if I create the LinkButton with Label the Tooltip does set to"Gnome" but the Label not.

The only thing which seems to work is if I set its Propertie:

g_object_set( linkButton, "label", "GTK", NULL );

Linux Mint 19.2 Tina
GCC 9.2.1
GTK 3.22.30

Here is the Code I use:

#include <gtk/gtk.h>

void load_css ( void );
GtkWidget *createWindow ( const gint width, const gint height, const gchar *const title );
GtkWidget *createGrid   (  gboolean row, gboolean col );

int main ( void )
{
    GtkWidget *window;
    GtkWidget *grid;
    GtkWidget *linkButton;
    /// ***
    gtk_init ( NULL, NULL );
    load_css();

    /// ***
    window = createWindow ( 300, 300, "My App" );

    /// ***
    grid   = createGrid ( FALSE, TRUE );
    gtk_container_add ( GTK_CONTAINER ( window ), grid );
    /// ***
    linkButton = gtk_link_button_new_with_label ( "Gnome", "https://www.discourse.gnome.org/" );
    ///g_object_set( linkButton, "label", "GTK", NULL );
    /// ***
    gtk_container_add ( GTK_CONTAINER ( grid ), linkButton );
    /// ***
    gtk_widget_show_all ( window );
    gtk_main ();
}

void load_css ( void )
{
    GtkCssProvider *provider;
    GdkDisplay     *display;
    GdkScreen      *screen;
    /// ***
    const gchar *css_style_file = "style.css";
    GFile *css_fp               = g_file_new_for_path ( css_style_file );
    GError *error               = 0;
    /// ***
    provider = gtk_css_provider_new ();
    display  = gdk_display_get_default ();
    screen   = gdk_display_get_default_screen ( display );
    /// ***
    gtk_style_context_add_provider_for_screen   ( screen, GTK_STYLE_PROVIDER ( provider ), GTK_STYLE_PROVIDER_PRIORITY_APPLICATION );
    gtk_css_provider_load_from_file             ( provider, css_fp, &error );
    /// ***
}

GtkWidget *createWindow ( const gint width, const gint height, const gchar *const title )
{
    GtkWidget *window;
    window = gtk_window_new         ( GTK_WINDOW_TOPLEVEL );
    gtk_window_set_title ( GTK_WINDOW ( window ), title );
    g_signal_connect                ( window, "destroy", gtk_main_quit, window );
    gtk_window_set_default_size     ( GTK_WINDOW ( window ), width, height );
    gtk_container_set_border_width  ( GTK_CONTAINER ( window ), 25 );
    return window;
}

GtkWidget *createGrid (  gboolean row, gboolean col )
{
    GtkWidget *grid = gtk_grid_new ();
    /// ***
    gtk_grid_set_row_homogeneous    ( GTK_GRID ( grid ), row );
    gtk_grid_set_column_homogeneous ( GTK_GRID ( grid ), col );
    /// ***
    return grid;
}

Based of its properies the GtkLinkButton does not have the Label properties, this means if I understand right that There is no Label for this LinkButton.

I thought there is something like Setting the “uri” and settings the “uri label” as well.

This means that the following call:

g_object_set( linkButton, "label", "GTK", NULL );

Changes the Link of the button.

I was thinkong that the LinkButton behaves like : s

gtk_link_button_set_uri()

and:

gtk_link_button_set_uri_label()

But it does not.

[ebassi (Emmanuele Bassi)]

The prototype for gtk_link_button_new_with_label() is:

GtkWidget *
gtk_link_button_new_with_label (const char *uri,
                                const char *label);

So you should call it with:

linkButton = gtk_link_button_new_with_label ( "https://www.discourse.gnome.org/", "Gnome" );

If you do that, you’ll see that the label is correctly set to “Gnome”.

Oh, that was a silly mistake.
I wonder how did I mismatched those arguments.
