image - PHP GTK button click -

I'm trying to change this button background when You click it and this is what I have:

  & lt ;? Php if (! Class_exists ('gtk')) {Dead ("Please load php-gtk2 module in your php.ini \ r \ n";); } Function location () {return dynamism (__ file__); }; $ Wnd = new GtkWindow (); $ Wnd-> Set_top ('image viewer'); $ Wnd-> Set_resizable (wrong); $ Wnd-> Set_position (GTK_WIN_POS_CENTER); $ Wnd-> Connect_system ('deleted', array ('gtk', 'main_quit')); $ Im = GtkImage :: new_from_file (loc (). "\ Bg.jpg"); $ Btn = new gtk button; $ Btn- & gt; Set_image ($ im); $ Btn- & gt; Clicked (function () {$ im = GtkImage :: new_from_file (loc (). "\ Bg2.jpg"); $ btn- & gt; set_esize ($ im);}); $ Wnd-> Add ($ btn); $ Wnd-> Show_all (); Gtk :: main (); ? & Gt;

Why does not this work?

I think $ btn-> gt; ; Clicked (function () { part is the problem.

  emits   $ btn-> clicked > on the signed signal. What you want to do  connect  a function for the signal: Connected ('clicked', 'change_background'); function changes_background ($ billboard) {$ im = GtkImage :: new_from_file (loc (). "\" Bg2.jpg "); $ pocket-> set_isize ($ im);}

IronPython in C#: No module named xmlrpclib -



    I am trying to create a web application with an interactive console for IronPython. When I try to import xmlrpclib into the General console of IronPython, it works. However, if I use IronPython inside my C # code, then it does not put an exception "a module named xmlrpclib", is it a known issue? Any solution to solve this issue?   Here is the code:    var testcode = @ "import xmlrpclib; apiarver = xmlrpclib.ServerProxy ('address', allow_none = true); print APIServer.Hello () ; "; Mystream str = newest Mystream (); ScriptEngine Engine = Python. Cretegenine (); Engine. Retyme.io asset output (str, system text encoding. ASCII); Engine. Serial.io.setuperoutput (str, systemtext.edcoding.aspx); ScriptScope scope = engine.CreateScope (); ScriptSource src = engine.CreateScriptSourceFromString (testCode); Src.Execute (scope); Sorry for the silly question, it has come to know that there is a path used by IronPathon inside me.       The C # code was not correct. I ...






qt creator - QtCreator importing makefile projects -



    Have you ever tried importing Classic C ++ / project into Qt Creator?   Say that I wanted to use some libraries in my GUI project, which must be created. how can I do this?      In Qt Creator 2.0.1 you can import projects using only * * Cmake, * .creator, * .pro or * .qmlproject   Then switch to cmake and you can import the project into Qt builder (Welcome tab -> Open project ...).
