gtk_file_chooser_dialog error

Hello!

I'm trying to run this code:

Code:

gint doble_clic(GtkWidget *widget, GdkEventButton *event, gpointer data)
{
GtkWidget *dialog = gtk_file_chooser_dialog_new (
                    "test", 
                    GTK_WINDOW (widget->parent), 
                    GTK_FILE_CHOOSER_ACTION_OPEN,
                    GTK_STOCK_CANCEL, // button text
                    GTK_RESPONSE_CANCEL, // response id
                    GTK_STOCK_OPEN, // button text
                    GTK_RESPONSE_ACCEPT, // response id
                    NULL); // end button/response list 

if(gtk_dialog_run(GTK_DIALOG (dialog)) == GTK_RESPONSE_ACCEPT)
  {
  gchar *filename;
  filename = gtk_file_chooser_get_filename(GTK_FILE_CHOOSER (dialog));
  printf("%s\n",filename);               
  g_free (filename);
  }
   
   
gtk_widget_destroy (dialog); 

return FALSE;
}

but it returns:
GLib-GIO-WARNING **: Could not initialize inotify
Any help?.

Another warning:

Unable to find default local directory monitor type

What's wrong?

I'm getting the same issue. Any help?

Hi,

Without knowing what you are doing to reproduce the errors, I am sure no one would be able to help you fix the errors that have occurred. Just like with the first person on this very old thread.

The original code sample is too short and does not tell where or how the error happens.

Hi errol,

Please find below my code:

/**************
#include<iostream>
using namespace std;
#include<gtk/gtk.h>

GtkWidget *window=NULL;

void insertFromListCb( GtkWidget *insert)
{

GtkWidget *dialog;
char *fileName;
dialog = gtk_file_chooser_dialog_new ("Open File",
GTK_WINDOW(window),
GTK_FILE_CHOOSER_ACTION_OPEN,
GTK_STOCK_CANCEL, GTK_RESPONSE_CANCEL,
GTK_STOCK_OPEN, GTK_RESPONSE_ACCEPT,
NULL);
if (gtk_dialog_run (GTK_DIALOG (dialog)) == GTK_RESPONSE_ACCEPT)
{
fileName = gtk_file_chooser_get_filename (GTK_FILE_CHOOSER (dialog));
cout<<"fileName =" << fileName << endl;
}

gtk_widget_destroy (dialog);
}

int main( int argc, char *argv[])
{
gtk_init( &argc, &argv);

GtkBuilder *builder= gtk_builder_new();
GtkWidget *insert= NULL;

gtk_builder_add_from_file( builder, "temp.xml", NULL);

window= GTK_WIDGET(gtk_builder_get_object( builder, "window"));
insert= GTK_WIDGET(gtk_builder_get_object( builder, "insert"));

g_signal_connect( insert, "clicked", G_CALLBACK(insertFromListCb), NULL);
gtk_widget_show_all(window);
gtk_main();
return 1;
}

I was unable to reproduce your error on my system. May be you have something missing from your install which is not monitoring the changes in the file system.

Note in your original code you have done some possible errors. First you should return 0 from main unless you really want to indicate to the operating system that the application had an error. Try to avoid the use of "using namespace", this is considered bad practice and defeats the point of name spaces.

I have also re-written your code to use gtkmm, which is the C++ binding for GTK since you are using C++. This is just an example and does not have full error checking.
Use this to compile (I am using gtkmm 3, this should also work with gtkmm 2 if you substitute gtkmm-2.4 instead of gtkmm-3.0)

Code:

gcc chisr.cc `pkg-config --libs --cflags gtkmm-3.0` -o chisr

Code:

#include<iostream>

#include<gtkmm.h>


Gtk::Window *window;


void insertFromListCb()
{
    Gtk::FileChooserDialog dialog(*window, "Open File");
    dialog.add_button(Gtk::Stock::CANCEL, Gtk::RESPONSE_CANCEL);
    dialog.add_button(Gtk::Stock::OPEN, Gtk::RESPONSE_ACCEPT);

    if (dialog.run() == Gtk::RESPONSE_ACCEPT) {
        std::cout << "filename = " << dialog.get_filename() << std::endl;
    }
}


int main(int argc, char *argv[])
{
    Gtk::Main kit(argc, argv);

    Gtk::Button *insert;

    Glib::RefPtr<Gtk::Builder> builder = Gtk::Builder::create_from_file("temp.xml");
    builder->get_widget("window", window);
    builder->get_widget("insert", insert);

    insert->signal_clicked().connect(sigc::ptr_fun(&insertFromListCb));

    window->show_all();
    kit.run(*window);

    return 0;
}
