GTK窗口置顶资料整理
在GTK中提供了下列几种窗口置顶函数：
gtk_window_set_keep_above(GTK_WINDOW(window),TRUE); //xfce下不起作用
gtk_window_set_type_hint (GTK_WINDOW(window),GDK_WINDOW_TYPE_HINT_DOCK); // 大多数desk panel使用的方式
?
示例代码：
/*** gcc always-top-window.c -o always-top-window `pkg-config --cflags --libs gtk+-2.0`*/#include <gtk/gtk.h>void destroy( GtkWidget *widget, gpointer data ){ gtk_main_quit ();}int main( int argc, char *argv[] ){ GtkWidget *window; GtkWidget *button; gtk_init (&argc, &argv); window = gtk_window_new (GTK_WINDOW_TOPLEVEL); g_signal_connect (G_OBJECT (window), "destroy", G_CALLBACK (destroy), NULL); gtk_container_set_border_width (GTK_CONTAINER (window), 10); button = gtk_button_new_with_label ("Hello World"); g_signal_connect_swapped (G_OBJECT (button), "clicked", G_CALLBACK (gtk_widget_destroy), window); gtk_container_add (GTK_CONTAINER (window), button); /* always on top */ // type1: gtk_window_set_keep_above // not work normal on xfce but can use on gnome // gtk_window_set_keep_above(GTK_WINDOW(window),TRUE); // type2: gtk_window_set_type_hint can use on xfce and gnome // gtk_window_stick() is [optional] gtk_window_set_type_hint (GTK_WINDOW(window),GDK_WINDOW_TYPE_HINT_DOCK); // gtk_window_set_type_hint (GTK_WINDOW(window), GDK_WINDOW_TYPE_HINT_DESKTOP); // gtk_window_stick (GTK_WINDOW(window)); gtk_widget_show (button); gtk_widget_show (window); gtk_main (); return 0;}
