使用GtkBuilder時無法更改GtkWindow大小

Question

我正在使用帶有Glade XML文件的GtkBuilder。我想將窗口大小改爲全屏，而不使用gtk_window_fullscreen方法（因爲這需要在沒有窗口管理器的情況下工作），所以我得到屏幕尺寸並製作窗口大小。當我以編程方式創建小部件時，這用於工作，但是當我切換到Glade/GtkBuilder時，該窗口與Glade編輯器中的小尺寸相同。我需要用GtkBuilder做些什麼嗎？下面的代碼：

#include <gtk/gtk.h> 

int main(int argc, char *argv[]) { 
    gtk_init(&argc, &argv); 

    GtkBuilder *builder = gtk_builder_new(); 
    gtk_builder_add_from_file(builder, "dm.ui", NULL); 

    GObject *window = gtk_builder_get_object(builder, "window"); 

    // Make full screen 
    GdkScreen *screen = gdk_screen_get_default(); 
    gint height = gdk_screen_get_height(screen); 
    gint width = gdk_screen_get_width(screen); 
    gtk_window_set_default_size(GTK_WINDOW(window), width, height); 

    g_signal_connect(window, "destroy", G_CALLBACK(gtk_main_quit), NULL); 

    gtk_main(); 
} 

這裏的XML文件，dm.ui：

您可以嘗試使用

void gtk_widget_set_size_request(GtkWidget *widget, gint width, gint height); 

，或者您可以使用格萊德調整「默認的GtkWindow性質寬度「和」默認高度「，而不是硬編碼它。 讓我知道結果。 p.s：這就是爲什麼我討厭格萊德:(
