Caching the result produced by Gtk::Builder?
Hi, I have a list-view and a tabbed detail-view of things. If I middle-click on an item in the list-view, I want to show the details in the detail-view in a new tab. This tab is currently build from a glade-file, i.e. I use Gtk::Builder for that. The problem is, that the builder (of course) needs some time to parse the file and so on. From the user-perspective its not acceptable to wait 1 sec. or something everytime a new tab is loaded. Is there a way to cache the result of Gtk::Builder or another way to speed that up? Thanks in advance! Best regards, Nils Asmussen ___ gtkmm-list mailing list gtkmm-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtkmm-list
Re: Caching the result produced by Gtk::Builder?
Ok, forget it. After posting the question I wondered why it takes *that* long, because 1 sec. or something is really a bit long on modern systems ;) Therefore I searched a bit and it turned out that my auto-scaling image causes the long load-times. More precisely, Gdk::Pixbuf::scale_simple() takes a huge amount of time if width and height is both 1 (apparently, on_size_allocate of the image is called with 1x1 at the beginning). Sometimes it gets even in an endless loop. Is this a known bug? Anyway, the problem is solved now because if I prevent the 1x1-problem, its really fast :) Thanks anyway.

Best and esiest to implemet pthread , GLib::Thread , GLib::Dispatcher
Hello I have made small gtkmm program that download some files from Internet by using libcurl.. But when the program start downloading the files it Freez until it finish (cuz of single thread??).. I knew that I must implement multi-threading to solve the problem ... I have 3 classes in the program : WINDOW , APP , CURL // here are some brief of the program CURL contains CURLREAD function to download the files and some helper functions APP contains other utils of program and contains getPKG() which get the URLS and download the files throught the object curl.curlread(url ,,,) Window has progressBAR CURL is object on APP and APP is object on WINDOW which one I should implement pthread , GLib::Thread or GLib::Dispatcher ?! ___ gtkmm-list mailing list gtkmm-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtkmm-list
Re: Best and esiest to implemet pthread , GLib::Thread , GLib::Dispatcher
Hi Kaiser, This one way I would approach this problem. 1. Launch a GLib::Thread to download the files. The API is quite nice and easy to use. 2. Register a timeout function on the main gtk loop that periodically checks (maybe once every half second) on the status of the thread you launched in 1 ( see http://developer.gnome.org/gtkmm-tutorial/3.2/sec-timeouts.html.en ). This can safely update anything on the GUI since it's invoked from the main loop. Update any GUI related things (progress bar, error/success indications, etc) using this function. Consider using a Glib::Mutex to facilitate safe communication between the two threads, i.e. synchronizing access to any shared buffer. Good luck!
