Gtk TextView在某些情况下显示的文字会有白色的背景框，显得跟界面格格不入，如下图所示：上图的源码如下：


#include <gtk/gtk.h>

gboolean key_press ( GtkWidget *window, GdkEventKey *event, gpointer *data );

int main(int argc, char **argv)
{
    GtkWidget *window;
    gtk_init(&argc, &argv);

    window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
    gtk_window_set_default_size(GTK_WINDOW(window), 400, 300);
    gtk_window_set_title(GTK_WINDOW(window), "");

    GtkWidget *view = gtk_text_view_new();
    GtkTextBuffer *buf = gtk_text_view_get_buffer(GTK_TEXT_VIEW(view));
    gtk_text_buffer_set_text ( buf, "窗含西岭千秋雪\n门泊东吴万里船", -1); 
    gtk_text_view_set_editable ( GTK_TEXT_VIEW(view), FALSE );

    GtkWidget *hBox = gtk_box_new ( GTK_ORIENTATION_VERTICAL, 0 );
    gtk_container_add ( GTK_CONTAINER(window), hBox );
    gtk_box_pack_start (GTK_BOX(hBox), view, 0, 0, 0);

    //GdkColor windowColor = gtk_widget_get_style(window)->bg[GTK_STATE_NORMAL]; 
    //gtk_widget_modify_bg ( view, GTK_STATE_NORMAL, &windowColor );

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

    g_signal_connect(G_OBJECT(window), "key-press-event", \
    G_CALLBACK(key_press),NULL);

    gtk_widget_show_all(window);
    gtk_main();

    return 0;
}

gboolean key_press ( GtkWidget *window, GdkEventKey *event, gpointer *data ) {
    if ( event->state ==  GDK_CONTROL_MASK ) {
        if ( event->keyval == GDK_KEY_c) {
            gtk_main_quit();
        }
    }
}

#include <gtk/gtk.h>

gboolean key_press ( GtkWidget *window, GdkEventKey *event, gpointer *data );

int main(int argc, char **argv)

{

GtkWidget *window;

gtk_init(&argc, &argv);

window = gtk_window_new(GTK_WINDOW_TOPLEVEL);

gtk_window_set_default_size(GTK_WINDOW(window), 400, 300);

gtk_window_set_title(GTK_WINDOW(window), "");

GtkWidget *view = gtk_text_view_new();

GtkTextBuffer *buf = gtk_text_view_get_buffer(GTK_TEXT_VIEW(view));

gtk_text_buffer_set_text ( buf, "窗含西岭千秋雪\n门泊东吴万里船", -1);

gtk_text_view_set_editable ( GTK_TEXT_VIEW(view), FALSE );

GtkWidget *hBox = gtk_box_new ( GTK_ORIENTATION_VERTICAL, 0 );

gtk_container_add ( GTK_CONTAINER(window), hBox );

gtk_box_pack_start (GTK_BOX(hBox), view, 0, 0, 0);

//GdkColor windowColor = gtk_widget_get_style(window)->bg[GTK_STATE_NORMAL];

//gtk_widget_modify_bg ( view, GTK_STATE_NORMAL, &windowColor );

g_signal_connect(G_OBJECT(window), "destroy", \

G_CALLBACK(gtk_main_quit),NULL);

g_signal_connect(G_OBJECT(window), "key-press-event", \

G_CALLBACK(key_press),NULL);

gtk_widget_show_all(window);

gtk_main();

return 0;

}

gboolean key_press ( GtkWidget *window, GdkEventKey *event, gpointer *data ) {

if ( event->state == GDK_CONTROL_MASK ) {

if ( event->keyval == GDK_KEY_c) {

gtk_main_quit();

}
