Public bug reported:
I am using appindicator-1.0 in conjunction with Gtk+2.0 menu. Menu
consist of constant items and many dynamically added items. If the
screen pixel resolution is not so good as it must be then the last menu
items are not visible. Ubuntu 16.04 automatically add top and bottom
bars with "^" and "v" arrows to scroll menu when mouse pointer is over
these bars. But in Linux Ubuntu 18.04 (and 19.04 too) such scrolling
bars are not appearing.
On the other hand menu scrolling is working fine anywhere into usual GTK
window with menu bar (without using appindicator). Ubuntu 16.04 and
Ubuntu 18.04 use the same 12.10.1 libappindicator version.
Here is the test c program which illustrates the issue. It works fine in
Linux Ubuntu 16.04 and has the described above problem in Linux 18.04:
#include <gtk/gtk.h>
#include <libappindicator/app-indicator.h>
#define LOGO_PNG "/home/super/my-project/menu-test/logo.png"
AppIndicator* c_indicator;
GtkWidget* c_menu;
void menu_quit_cb(GtkMenuItem* menuitem, gpointer user_data)
{
gtk_main_quit();
}
int main(int argc, char *argv[])
{
gtk_init(&argc, &argv);
int i;
GtkWidget* item;
char title[128];
c_menu = gtk_menu_new();
item = gtk_menu_item_new_with_label("Quit");
g_signal_connect(item, "activate", G_CALLBACK(menu_quit_cb), NULL);
gtk_menu_shell_append(GTK_MENU_SHELL(c_menu), item);
gtk_widget_show(item);
gtk_menu_shell_append(GTK_MENU_SHELL(c_menu),
gtk_separator_menu_item_new());
for (i = 1; i <= 100; ++i) {
snprintf(title, sizeof(title), "Item #%03u", i);
item = gtk_menu_item_new_with_label(title);
gtk_menu_shell_append(GTK_MENU_SHELL(c_menu), item);
gtk_widget_show(item);
}
//
c_indicator = app_indicator_new("Menu Test", LOGO_PNG,
APP_INDICATOR_CATEGORY_APPLICATION_STATUS);
app_indicator_set_status(c_indicator, APP_INDICATOR_STATUS_ACTIVE);
app_indicator_set_icon(c_indicator, LOGO_PNG);
app_indicator_set_menu(c_indicator, GTK_MENU(c_menu));
gtk_main();
return 0;
}
