问题 I'm trying to learn how to make GUIs using gtk+ 3.0. I want to pass a simple argument, an integer, to a callback function, so that when I press the button the value of the argument changes. Here's my code: #include <gtk/gtk.h> void buttonFunction(GtkWidget * widget, gpointer data, int & n){ n = 1; } int main(int argc, char ** argv){ int n = 0; GtkWidget * window; GtkWidget * button; gtk_init(&argc,&argv); window = gtk_window_new(GTK_WINDOW_TOPLEVEL); button = gtk_button_new_with_label("Osss")

问题 is it possible to store cookies to file when you use webkit and reuse it again next time when I run my application? 回答1: I know its old question and have been looking for the answer all over the place.

问题 I got this code that works for the left mouse click on a button but how would I use to get the right mouse click signal: g_signal_connect(G_OBJECT(button), "clicked", G_CALLBACK(button-action), NULL); 回答1: A simple way to listen for any mouse clicks, be it left or right would be this: g_signal_connect( G_OBJECT(button) "button-press-event", G_CALLBACK(btn_press_callback), NULL ); Then, for the callback function: gboolean btn_press_callback(GtkWidget *btn, GdkEventButton *event, gpointer

问题 I have tasted both Qt 4.x/5.x and GTKmm 3.x and I really like GTKmm over Qt. Now I have just discovered that GTKmm 3.x doesn't offer a Windows porting, they also do not offer a Mac porting, basically I can't find nothing but libraries/sources/binaries for Linux. Apparently the Windows support ( I'm not sure about the situation for the Mac OS stuff ) was dropped in the 2.x era and it's still not-existing today. I have planned to use GTK 3.x for specific reasons, especially for some new

问题 I'm trying to add to the "recently used" files list from Python 3 on Ubuntu. I am able to successfully read the recently used file list like this: from gi.repository import Gtk recent_mgr = Gtk.RecentManager.get_default() for item in recent_mgr.get_items(): print(item.get_uri()) This prints out the same list of files I see when I look at "Recent" in Nautilus, or look at the "Recently Used" place in the file dialog of apps like GIMP. However, when I tried adding an item like this (where /home
