Well, firstly I'm very glad for all the indications that I receive from everybody.If it was possible I will pay a beer to everybody.....or more than one in more than one case :)
>$win->btnHide()->SetFocus(); #fails on run-time, btnHide? I'm going to include the event that is sorrounding my head ...this is an event that comes from a TreeView, I comment some thinks in bold ,that is: sub Tree_NodeClick { $posdinsalu=0; for my $est_alu (@alumne) { if ($est_alu->{Arbre}==$_[0]) { if (!exists ($w_analisi[$posdinsalu])) { # I Create dinamically a window that depens on a variable $w_analisi[$posdinsalu] = Win32::GUI::Window->new ( -top => 0, -left => 0, -width => 600, -height => 400, -minsize => [600,400], -text => "Comentaris respecte $est_alu->{Nom}", -name => "Mailtool::tutor::e_w_analisi_$posdinsalu",); $canviat[$posdinsalu]=0; open ENTSIS,"<sessions/${posdinsalu}${noms}.txt"; $res =<ENTSIS>; chop ($res); $toteltex=$res; while($res =<ENTSIS>) { chop ($res); $toteltex=$toteltex."\r\n".$res; } close ENTSIS; $comentaris[$posdinsalu] =$w_analisi[$posdinsalu]->AddTextfield( -foreground => [0, 0, 0], # Color del text: negre -font => $Mailtool::mevesfonts::fo_normal, -left => 10, -top => 10, -height => 350, -width => 480, -name => "Mailtool::tutor::t_comentari_$posdinsalu", -addstyle => WS_CHILD | WS_VISIBLE | WS_VSCROLL | ES_LEFT | ES_MULTILINE | ES_AUTOVSCROLL,); $comentaris[$posdinsalu]->Text("${toteltex}"); $b_guardar[$posdinsalu] = $w_analisi[$posdinsalu]->AddButton( -text => "GUARDAR", # Text al botó -font => $Mailtool::mevesfonts::fo_normal, -left => 510, -top => 85, -height => 25, -name => "Mailtool::tutor::b_$posdinsalu",); ## Ens cal fer us de eval per al tractament dels events de les finestres dinà miques. ## Aldo told me about the use of eval....it works good eval qq{ sub Mailtool::tutor::b_${posdinsalu}_Click { Mailtool::tutor::b_Click($posdinsalu);} sub Mailtool::tutor::e_w_analisi_${posdinsalu}_Terminate { Mailtool::tutor::e_w_analisi_Terminate($posdinsalu);} sub Mailtool::tutor::t_comentari_${posdinsalu}_Change { Mailtool::tutor::t_comentari_Change($posdinsalu);} }; # Here stars the problem, the new windows appears for miliseconds but goes beneath the $w_tutor $w_analisi[$posdinsalu]->Show(); $w_analisi[$posdinsalu]->SetForegroundWindow(); $w_analisi[$posdinsalu]->SetFocus(); } else { # In case that I reopen a dinamic window the first time it doesn't open, but yes the next time, after another one, for example $w_analisi[$posdinsalu]->Show(); } } } return 0; } A lot of thaks to everybody !!!
