I add two buttons into dialog->vbox ,then click one to
remove the other,but after remove
the other,the dialog size not change to size which
just is suit for a button.
I even use
gtk_widget_set_size_request(dialog,width,height),it
seem that only when
width and height greater than orginal dialog
size,dialog change bigger,but when set height and
width smaller than orginal dialog size,it do
nothing,there is still blank area in the dialog which
used for the other button before. code below
#include <gtk/gtk.h>
#define A &argc,&argv
#define GW GtkWidget*
#define GB gtk_button_new_with_label("xxx")
#define BP gtk_box_pack_start
GW dialog;
GW b;
GW b1;
void yes(GtkWidget* gtkwidget,gpointer data)
{
gtk_container_remove(GTK_CONTAINER(GTK_DIALOG(dialog)->vbox),b1);
gtk_widget_show_all(dialog);
}
int
main (int argc, char *argv[])
{gtk_init(A);
dialog=gtk_dialog_new();
b= GB ;
b1= GB ;
BP (GTK_BOX(GTK_BP
(GTK_BOX(GTK_DIALOG(dialog)->vbox),b,FALSE,FALSE,0);
BP (GTK_BOX(GTK_BP
(GTK_BOX(GTK_DIALOG(dialog)->vbox),b1,FALSE,FALSE,0);
gtk_widget_show_all(dialog);
g_signal_connect(G_OBJECT(b),"clicked",G_CALLBACK(yes),b1);
gtk_main();
return ;
}
