Re: glade and/or gtkmm, insert a FileChooserDialog inside a Notebook tab

Hi,

I appreciate all help you guys provided so far, but I shall try to
summarize. I'm using gtkmm, it's a C++ API not C nor python. It's
a wrapper of the C API.

with gtkmm when you want to "run" a dialog you use this
method :

int Gtk::Dialog::run() 
https://developer.gnome.org/gtkmm/stable/classGtk_1_1Dialog.html#adc98a1e747613c9b6cb66c238f6f8da6

this method loops until the dialog emits the
`Gtk::Dialog::signal_response()` signal, and return an `int`. This
`int` depend of the button you clicked, for example, if I set the
response value of the cancel button to 1, then, when I clicked on
cancel, `run()` return 1.

So when I call the FileChooserDialog, this loop locks the next
operations in my program until the end of `run()`. If I use a
`FileChooserWidget`, it seems, that there is no way to get the same
behaviour.

`run()` seems to be the wrapper of `gtk_dialog_run()` then what Tristan
wrote,

that's what I feared...

I do this, the tab is hide until the user ask to save. Then, the
tab is shown and the notebook get the signal to switch on this tab. I
plan (this part is not done yet) (or planned) to not allow to switch on
another tab (maybe hidding the tabs bar) until the user click on Ok or
Cancel.

Of course I can still make some waiting function, or maybe it's
possible to get what I would like with plug'n'socket, even it's in
the same process.

for now I will stay with a FileChooserDialog, I'll see in the future if
it will lead to any problem (on small screen). Any suggestion is still
welcome.
