I am currently struggling with screen updates (for the find-dialog of FBReader). I am using the erutils-functions with a wrapper file I copied from notepad (notepad_display_sched.cpp).
I saw that in notepad the following calls are made:

                    notepad_stop_display_update();
                    GtkWidget* infodialog = gtk_message_dialog_new(...)
                    notepad_on_timeout_display_yield(400, DM_HINT_FULL);
                    gtk_dialog_run(GTK_DIALOG(infodialog));

If I use the same order of instructions (stop_display_update(), create part of the dialog and then on_timeout_display_yield() ) I do not get a screen update, so the dialog is not shown. Also calling stop_display_update(), display_update((void*)DM_HINT_FULL) and start_display_update() does not lead to an update.

My modified function:

Spoiler:

bool ZLGtkDialog::run() {
bool ok;

printf("ZLGtkDialog::run\n");
// stop refresh, to be able to force a refresh
dr_stop_display_update();
if (!myIsPacked) {
gtk_box_pack_start(GTK_BOX(myDialog->vbox), GTK_WIDGET(((ZLGtkDialogContent*)myTab)->widget()), true, true, 0);
myIsPacked = true;
}
gtk_widget_show_all(GTK_WIDGET(myDialog));
// refresh screen
dr_on_timeout_display_yield(400, DM_HINT_FULL);

printf("ZLGtkDialog::run-before\n");
ok = gtk_dialog_run(GTK_DIALOG(myDialog)) == GTK_RESPONSE_ACCEPT;

// stop refresh, to be able to force a refresh
dr_stop_display_update();
dr_display_update((void*)DM_HINT_FULL);
dr_start_display_update();

return ok;
}

I assume I am missing some clues, is there anyone with some more experience to give me some hints on how to continue?

Thanks,
Marcel
