Hello,

if you use a FileChooserWidget, you will most likely want to create your
own open/save button, and connect to its clicked signal. When the button is
clicked, you should run gtk_file_chooser_get_files() (I assume it's
::get_files() in the gtkmm API) to get the list of selected files in the
file chooser widget. Another option is to connect to the file chooser's
file-activated signal, but that may cause other problems.

Hope that helps!

Best,
Gergely

I appreciate all help you guys provided so far, but I shall try to<br>
summarize. I&#39;m using gtkmm, it&#39;s a C++ API not C nor python. It&#39=
;s<br>
a wrapper of the C API.<br>
<br>
with gtkmm when you want to &quot;run&quot; a dialog you use this<br>
method :<br>
<br>
int Gtk::Dialog::run()<br>
<a href=3D"https://developer.gnome.org/gtkmm/stable/classGtk_1_1Dialog.html=

me.org/gtkmm/stable/classGtk_1_1Dialog.html#adc98a1e747613c9b6cb66c238f6f8d=
a6</a><br>
<br>
this method loops until the dialog emits the<br>
`Gtk::Dialog::signal_response()` signal, and return an `int`. This<br>
`int` depend of the button you clicked, for example, if I set the<br>
response value of the cancel button to 1, then, when I clicked on<br>
cancel, `run()` return 1.<br>
<br>
So when I call the FileChooserDialog, this loop locks the next<br>
operations in my program until the end of `run()`. If I use a<br>
`FileChooserWidget`, it seems, that there is no way to get the same<br>
behaviour.<br>
<br>
`run()` seems to be the wrapper of `gtk_dialog_run()` then what Tristan<br>
wrote,<br>
<br>
&gt; you cannot have gtk_dialog_run() without a dialog, that&#39;s sort<br>
&gt; of the whole point, the dialog is then automatically modal and<br>
&gt; exclusive, so you only get the response once it&#39;s done - an attrib=
ute<br>
&gt; of it being a dialog is of course, that it is a separate window.<br>
<br>
that&#39;s what I feared...<br>
<br>
&gt;<br>
&gt; If you want a filechooser widget in a notebook tab, then you will have=
<br>
&gt; to provide some control as to when you want to try to save the file,<b=
r>
&gt;<br>
I do this, the tab is hide until the user ask to save. Then, the<br>
tab is shown and the notebook get the signal to switch on this tab. I<br>
plan (this part is not done yet) (or planned) to not allow to switch on<br>
another tab (maybe hidding the tabs bar) until the user click on Ok or<br>
Cancel.<br>
<br>
Of course I can still make some waiting function, or maybe it&#39;s<br>
possible to get what I would like with plug&#39;n&#39;socket, even it&#39;s=
 in<br>
the same process.<br>
<br>
&gt; I really recommend that you consider allowing a popup modal dialog<br>
&gt; for saving things, doing this in a notebook tab is rather unintuitive<=
br>
&gt; (i.e., it&#39;s safer when a window takes control, and the user is not=
<br>
&gt; allowed to do anything until they decide what file to save as, or<br>
&gt; decide to cancel and not save at all).<br>
&gt;<br>
&gt; Cheers,<br>
&gt;=C2=A0 =C2=A0 =C2=A0-Tristan<br>
<br>
for now I will stay with a FileChooserDialog, I&#39;ll see in the future if=
<br>
it will lead to any problem (on small screen). Any suggestion is still<br>
welcome.<br>
