hey folks :D i'm trying to simulate the GDK_ENTER_NOTIFY event to force entry to show the tooltip. I set up a GdkEventCrossing structure and send using gdk_event_put, but my entry do not show the tooltip. My test code is like this one:

Code: (C)

#include <stdio.h>
#include <gtk/gtk.h>
#include <gtk/gtktooltip.h>

GtkWidget* window;
GtkWidget* fixed;
GtkWidget* entry;
GtkWidget* button;
GtkTooltips* tooltip;
GdkEventCrossing *e;

void Callback(GtkWidget* poWidget, gpointer oThis)
{
gdk_event_put((GdkEvent *) e);
}

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

window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
gtk_widget_set_size_request (window, 800, 600);

fixed = gtk_fixed_new ();
gtk_widget_set_size_request (fixed, 800, 600);

entry = gtk_entry_new ();
gtk_widget_set_size_request (entry, 50, 50);

tooltip = gtk_tooltips_new ();
gtk_tooltips_set_tip (tooltip, entry, "TESTE TOOLTIP", NULL);

e = (gpointer)gdk_event_new(GDK_ENTER_NOTIFY);
e->window = entry->window;
e->send_event = 1; /* True if we're sending event. */
e->subwindow = entry->window;
e->time = GDK_CURRENT_TIME;
e->x = 0.0;
e->y = 0.0;
e->x_root = 0.0;
e->y_root = 0.0;
e->mode = GDK_CROSSING_NORMAL;
e->detail = GDK_NOTIFY_ANCESTOR;
e->focus = TRUE; /* Focus. */
e->state = 0; /* Key modifiers. */

button = gtk_button_new_with_label ("AAA");

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

g_signal_connect(GTK_OBJECT(button), "clicked", GTK_SIGNAL_FUNC(Callback), NULL);

gtk_fixed_put (GTK_FIXED(fixed), button, 20, 20);
gtk_fixed_put (GTK_FIXED(fixed), entry, 100,100);
gtk_container_add (GTK_CONTAINER(window), fixed);

gtk_widget_show_all (window);

//gtk_signal_emit_by_name(GTK_OBJECT(entry),"enter-notify-event",e); doesn't work either.

gtk_main ();

return 0;
}

My gtk version do not suport keyboard tooltip event inside entry widgets, and i'm not allowed to use another gtk version :(

Thanks for all!

Hey, sorry for this, but all i have to do is move the struct initialization to a place where the entry already has a parent, i.e: after:

Code: (C)
1 2 3 4 5	gtk_fixed_put (GTK_FIXED(fixed), entry, 100,100); gtk_container_add (GTK_CONTAINER(window), fixed); gtk_widget_show_all (window);

... Thanks for all anyway ;)
