Hi Aitor,
is this gtkmm3? For example, Gtk::VBox is deprecated,
I'm using Gtk::Grid.
Currently my application just core dumps :(.
The backtrace is:
Thread 1 "tstcpp" received signal SIGSEGV, Segmentation fault.

Frame #3 (the first that is my code) is:
#3 0x0000555555573871 in
LinuxChessboardWidget::LinuxChessboardWidget(this=0x5555563bd928,
drawable=0x5555563bd8a0, promotion=...,__in_chrg=<optimized out>,

164 add_action("ModeShowCandidates", sigc::mem_fun(*this,
&LinuxChessboardWidget::on_menu_mode_showcandidates));
Why would this core dump??
LinuxChessboardWidget is defined as:
class LinuxChessboardWidget : public cwmm::ChessPositionWidget, public
Gio::ActionMap
{
...
I have to derive from Gio::ActionMap because its constructor is protected.
The call to `add_action` above is to that class.
Can someone tell me what I'm doing wrong?
Carlo
