如何隱藏的Gtk彈出式窗口，當用戶clickes窗口

外面我使用GTK +和空地工具C. 它的父窗口彈出時，按鈕按下開發一個彈出窗口（飾非）。當用戶點擊此窗口時，我想銷燬或隱藏此彈出窗口。用戶可以單擊父窗口或任何其他窗口。我試圖捕獲GDK_FOCUS_CHANGE事件，但我無法捕獲此事件。有什麼辦法可以做到這一點？我如何知道點擊是在其他窗口上，然後彈出窗口？如何清楚彈出窗口失去了焦點？這樣我就可以隱藏它。相關的代碼如下：如何隱藏的Gtk彈出式窗口，當用戶clickes窗口

/* 
* Compile me with: 

gcc -o popup popup.c $(pkg-config --cflags --libs gtk+-2.0 gmodule-2.0) 
*/ 

#include <gtk/gtk.h> 

static void on_popup_clicked (GtkButton*, GtkWidget*); 
static gboolean on_popup_window_event(GtkWidget*, GdkEventExpose*); 

int main (int argc, char *argv[]) 
{ 
    GtkWidget *window, *button, *vbox; 

    gtk_init (&argc, &argv); 

    window = gtk_window_new (GTK_WINDOW_TOPLEVEL); 
    gtk_window_set_title (GTK_WINDOW (window), "Parent window"); 
    gtk_container_set_border_width (GTK_CONTAINER (window), 10); 
    gtk_widget_set_size_request (window, 300, 300); 
    gtk_window_set_position (GTK_WINDOW (window),GTK_WIN_POS_CENTER); 

    button = gtk_button_new_with_label("Pop Up"); 
    g_signal_connect (G_OBJECT (button), "clicked",G_CALLBACK (on_popup_clicked),(gpointer) window); 

    vbox = gtk_vbox_new (FALSE, 3); 
    gtk_box_pack_end(GTK_BOX (vbox), button, FALSE, FALSE, 5); 
    gtk_container_add (GTK_CONTAINER (window), vbox); 

    gtk_widget_show_all (window); 
    gtk_main(); 
    return 0; 
} 

void on_popup_clicked (GtkButton* button, GtkWidget* pWindow) 
{ 
    GtkWidget *popup_window; 
    popup_window = gtk_window_new (GTK_WINDOW_POPUP); 
    gtk_window_set_title (GTK_WINDOW (popup_window), "Pop Up window"); 
    gtk_container_set_border_width (GTK_CONTAINER (popup_window), 10); 
    gtk_window_set_resizable(GTK_WINDOW (popup_window), FALSE); 
    gtk_window_set_decorated(GTK_WINDOW (popup_window), FALSE); 
    gtk_widget_set_size_request (popup_window, 150, 150); 
    gtk_window_set_transient_for(GTK_WINDOW (popup_window),GTK_WINDOW (pWindow)); 
    gtk_window_set_position (GTK_WINDOW (popup_window),GTK_WIN_POS_CENTER); 
    g_signal_connect (G_OBJECT (button), "event", 
         G_CALLBACK (on_popup_window_event),NULL); 

    GdkColor color; 
    gdk_color_parse("#3b3131", &color); 
    gtk_widget_modify_bg(GTK_WIDGET(popup_window), GTK_STATE_NORMAL, &color); 


    gtk_widget_show_all (popup_window); 
} 

gboolean on_popup_window_event(GtkWidget *popup_window, GdkEventExpose *event) 
{ 
    if(event->type == GDK_FOCUS_CHANGE) 
     gtk_widget_hide (popup_window); 

    return FALSE; 
}

在這裏，我不能當用戶點擊父窗口或其他窗口隱藏這個彈出窗口。我怎樣才能做到這一點？

我要堅持用GTK + 2.14版本。

的變化：從GTK_WINDOW_POPUP

開關GTK_WINDOW_TOPLEVEL，反直覺的，但我無法弄清楚如何讓一個彈出窗口接受焦點。
添加gtk_window提示來防止彈出窗口在任務欄和尋呼機表示
故意將焦點設置在彈出窗口
設置GDK_FOCUS_CHANGE_MASK上GDK_WINDOW與gtk_widget_set_events（用於下一步驟必需）
連接到在彈出的窗口中focus-out-event
改變信號處理程序來處理不同的信號

竟被我d還建議閱讀GTK +源代碼，看看它在顯示時如何處理工具提示和菜單的彈出窗口......但這些通常是基於鼠標移出範圍而不是彈出失敗焦點本身而銷燬的。

得到它的工作！感謝您的關注。 – kbalar 2009-11-17 14:53:36

好交易。如果此答案對您有用，請隨時點擊答案旁邊的大複選標記。:) – mlibby 2009-11-17 15:13:15

偉大的解決方案，但有一個問題：主窗口可視化註冊焦點變化，通過不同的顏色着色（Windows 7）。這不應該發生（假）彈出窗口。任何想法來防止這種情況？ – schlamar 2012-10-12 09:35:22

您不需要在彈出窗口中設置鍵盤焦點。

你只需要捕獲鼠標您popup_window->window使用gdk_pointer_grab(...)與真owner_events和GDK_BUTTON_PRESS_MASK GdkEventMask參數。

然後你popup_window連接到"button-press-event"。如果*事件座標爲負數或高於popup_window大小，則在其處理程序內部隱藏/銷燬popup_window並釋放捕獲使用gdk_pointer_ungrab(...)。

另一種選擇是簡單地按下一個按鈕監聽器添加到父窗口。這樣做的好處是彈出窗口仍然看起來像一個彈出窗口（父窗口和它本身都可以同時激活）
