If your dialog run with gtk_dialog_run(). Then you must not to hide
your dialog if no file selected. My code for this:
const gchar *path;
// Create GtkFileSelection and set all properties
GtkWidget *OpenDlg = create_FileSelectionDialog();
do {
// Wait for dialog close
if (gtk_dialog_run(GTK_DIALOG(OpenDlg)) != GTK_RESPONSE_OK) {
// Exit if Cancel or so pressed
gtk_widget_destroy(GTK_WIDGET(OpenDlg));
return;
}
// Retrieve the path
path = gtk_file_selection_get_filename (GTK_FILE_SELECTION (OpenDlg));
// Test is returned filename a regular file
} while (!(g_file_test(path,G_FILE_TEST_EXISTS) &&
g_file_test(path,G_FILE_TEST_IS_REGULAR)));
// Get filename from full path
gchar *filename = g_path_get_basename(path);
...
g_free(filename);
// !!!!!!!!!!!!!!!!!!!! Destroy dialog only here !!!!!!!!!!!!!!!!!!!!!!!!!!
gtk_widget_destroy(GTK_WIDGET(OpenDlg));
