Re: How to make menu popdown?

["Wang Wallice" <hz_wallice hotmail com>]

Thanks for you answer.
Maybe my poor english confuse you,i want to create a submenu,items of this 
submenu should be horizontally array.So i firstly create a menu item of 
this submenu,it contains a hbox,hbox contains four buttons. I expect when i 
click one button,the submenu and its super menu could be popdown. My code 
is below,i expect when i click widget m_wiSubMenuButton1(or 
..Button2..),menu m_wiMenuControl could be popdown.
Any advice is welcome,thanks.

...
m_wiMenuBar = gtk_menu_bar_new ();
m_wiMenuBtn = gtk_menu_item_new_with_label ("Control");
m_wiMenuControl = gtk_menu_new ();
gtk_menu_item_set_submenu (GTK_MENU_ITEM (m_wiMenuBtn), m_wiMenuControl);

m_wiMenuItem1 = gtk_menu_item_new_with_label("Item1");
gtk_container_add (GTK_CONTAINER (m_wiMenuControl), m_wiMenuItem1);
m_wiMenuItem2 = gtk_menu_item_new_with_label("Item2");
gtk_container_add (GTK_CONTAINER (m_wiMenuControl), m_wiMenuItem2);
m_wiMenuItem3 = gtk_menu_item_new_with_label("Item3");
gtk_container_add (GTK_CONTAINER (m_wiMenuControl), m_wiMenuItem3);

m_wiSubMenu = gtk_menu_new();
gtk_menu_item_set_submenu (GTK_MENU_ITEM (m_wiMenuItem3), m_wiSubMenu);
m_wiSubMenuItem1 = gtk_menu_item_new_with_label("SubMenuItem1");
gtk_container_add (GTK_CONTAINER (m_wiSubMenu), m_wiSubMenuItem1);
m_wiSubMenuHBox = gtk_hbox_new (FALSE, 0);
gtk_container_add (GTK_CONTAINER (m_wiSubMenuItem1), m_wiSubMenuHBox);

m_wiSubMenuButton1 = gtk_button_new();
gtk_box_pack_start (GTK_BOX (m_wiSubMenuHBox), m_wiSubMenuButton1, FALSE, 
FALSE, 5);
m_wiSubMenuButton2 = gtk_button_new();
gtk_box_pack_start (GTK_BOX (m_wiSubMenuHBox), m_wiSubMenuButton2, FALSE, 
FALSE, 5);
m_wiSubMenuButton3 = gtk_button_new();
gtk_box_pack_start (GTK_BOX (m_wiSubMenuHBox), m_wiSubMenuButton3, FALSE, 
FALSE, 5);
m_wiSubMenuButton4 = gtk_button_new();
gtk_box_pack_start (GTK_BOX (m_wiSubMenuHBox), m_wiSubMenuButton4, FALSE, 
FALSE, 5);
