一个 困扰我很长时间的 GTK+ 里的问题,希望高手能给予帮助解答
今天写的GTK+的程序,程序如下:
1 #include <gtk/gtk.h>
2
3 gint x = 50;
4 gint y = 50;
5
6 void move_button( GtkWidget * widget, GtkWidget * fixed )
7 {
8 x = ( x + 30 ) % 300;
9 y = ( y + 50 ) % 300;
10 gtk_fixed_move( GTK_FIXED( fixed ), widget, x, y );
11 }
12
13
14 int main( int argc, char * argv[] )
15 {
16 GtkWidget * window;
17 GtkWidget * fixed;
18 GtkWidget * button;
19
20 gtk_init( & argc, & argv );
21
22 window = gtk_window_new( GTK_WINDOW_TOPLEVEL );
23 gtk_window_set_title( GTK_WINDOW(window) , "fixed container " );
24
25 gtk_signal_connect( GTK_OBJECT( window ), "destory ",
26 GTK_SIGNAL_FUNC( gtk_main_quit ) , NULL );
27
28 gtk_container_set_border_width( GTK_CONTAINER(window), 10 );
29
30 fixed = gtk_fixed_new();
31 gtk_container_add( GTK_CONTAINER( window ), fixed );
32 gtk_widget_show( fixed );
33 int i ;
34
35
36
37 for ( i = 1; i <= 3; i++ )
38 {
39 button = gtk_button_new_with_label( "press me " );
40 gtk_signal_connect( "GTK_OBJECT( button ) ", "clicked ",
41 GTK_SIGNAL_FUNC( move_button ), fixed );
42
43 gtk_fixed_put( GTK_FIXED( fixed ), button, i * 50, i * 50 );
44 gtk_widget_show( button );
45
46 }
47
48 gtk_widget_show( window );
49
50 gtk_main();
51 return 0;
52 }
编译的时候总是报gtk4.c: In function `main ':
gtk4.c:41: warning: passing arg 1 of `gtk_signal_connect ' from incompatible pointer type
然后运行报错
Gtk-WARNING **: gtk_signal_connect(): could not find signal "destory " in the `GtkWindow ' class ancestry
段错误
还有我的很多程序如果有 gtk_signal_connect( GTK_OBJECT( window ), "destory ",
GTK_SIGNAL_FUNC( gtk_main_quit ) , NULL );
的语句 运行结果都是 Gtk-WARNING **: gtk_signal_connect(): could not find signal "destory " in the `GtkWindow ' class ancestry
段错误
第一次发贴子,希望大家能帮助我
我的LINUX系统是 redhat linux enterprise 3 内核是 2.4.21-32.el
还望大家给与帮助,谢谢
[解决办法]
25 gtk_signal_connect( GTK_OBJECT( window ), "destory ",
26 GTK_SIGNAL_FUNC( gtk_main_quit ) , NULL );
1. "destory "应该是destroy吧。
40 gtk_signal_connect( "GTK_OBJECT( button ) ", "clicked ",
41 GTK_SIGNAL_FUNC( move_button ), fixed );
2.应该把 "GTK_OBJECT( button ) "引号去掉吧。
