Combo-box with scrollbar as the COMBO-BOX in LibreOffice that have in the list of FONTS

COMBOBOX  with  SCROLLBAR



Excuse  me   for  my question  .................... I am creating a
combo-box with scrollbar with GTK 3.0 and VALA (gtk) ......... .as  the
 COMBO-BOX  in   LibreOffice that have  in the   list of FONTS ..........
 GTK  3.0   have  not a  COMBO-BOX   with scrollbar ................... You
.. I could give an example of  CODE written in GTK 3.0 or VALA (gtk) or a
 PyGtk  3.0 . a example     COMBO-BOX with SCROLLBAR ......... or spend a
link of  a  website  ,  where I can get an example   of  COMBO-BOX with
SCROLLBAR    ....

I wrote an in GTK 3.0 widgets.

If .  I  active   a    POPUP WINDOW   (POPUP WINDOW=MENU ) with a
TOGGLEBUTTON... when you clicked the button to close the window.

1). First   . The  TOGGLEBUTTON is   off    .  the  POPUP WINDOW   is
hidden .
2) Then recently .  I can close the window.
To here   all works fine.


But I can not do the same with the buttons on the maximize and minimize
WINDOW ...... I must achieve the same effect as the widgets  ,   POPUP MENU
 and   COMBO-BOX  ,   with  these events .


If I  you   can help , I'll be grateful  .

When  , you  have a  time. you can constestarme.

Best   regards   . Mariano.



I show  .  the code I've written in GTK 3.0.
