Hello,

I'm just trying to create a very simple dialog , but I discovered a strange behavior. First I created a simple HildonDialog, after I created a GtkBox with a GtkLabel and an HildonEntry and setted the text on the entry through hildon_gtk_entry_set_placeholder_text () then I packaged the GtkBox in the HildonDialog's vbox. The result is that the entry did not display the placeholder text , it appear only when the screen goes black (not completly black).
Anyone know the reason of this behavior? How I can fix it ?

Thank you.

P.S. : I have a little piece of code to demostrate it, if necessary I can paste it there.

Just guessing, but did you call gtk_widget_show_all for the dialog?

Yes, I have gtk_widget_show_all ( GTK_WIDGET(d) ); where d is the HildonDialog.

The example would be nice to know exactly what you mean and to see how it behaves.

Thanks,

Daniel

Ok, there is the example :

Code:
#include <hildon/hildon.h>

int main ( int argc, char *argv[] )
{
        GtkWidget *dialog;
        HildonDialog *d;
        GtkWidget *box;
        GtkWidget *sentry;
        GtkWidget *cstatus;

        hildon_gtk_init (&argc, &argv);

        d = HILDON_DIALOG (hildon_dialog_new ());
        gtk_window_set_title (GTK_WINDOW (d), "Hi!");
        hildon_dialog_add_button (HILDON_DIALOG (d), GTK_STOCK_OK, GTK_RESPONSE_NONE);
        box = gtk_vbox_new(2,FALSE);
        cstatus = gtk_label_new("test");
        sentry = hildon_entry_new(HILDON_SIZE_AUTO);
        hildon_gtk_entry_set_placeholder_text (GTK_ENTRY (sentry), " THE TEST");
        gtk_box_pack_start(GTK_BOX(box), cstatus, TRUE,TRUE,0);
        gtk_box_pack_start(GTK_BOX(box), sentry, TRUE,TRUE,0);

        gtk_container_add ( GTK_CONTAINER(GTK_DIALOG(d)->vbox), box);
        gtk_widget_show_all ( GTK_WIDGET(sentry) );

        gtk_widget_show_all ( GTK_WIDGET(d) );

        gtk_dialog_run(GTK_DIALOG(d));
        return 0;

}

Just a guess, but could it be that the HildonEntry has the focus? AFAIK, once it has the focus the placeholder text is hidden. The screen dimming could take away the focus and thus make the text visible again.

Yes, that is the reason.
Now I'm going to check if there is a method to remove the focus from a GtkEntry.
Thank you!
