Was your custom view created dynamically (via an Access type)? If it
was just created as a standard statically allocated view type, it will
disappear when the submit handler is finished. Consider to two
On_Click events:
procedure On_Click1(Object : in out Gnoga.Gui.Base.Base_Type'Class) is
v : Gnoga.Gui.View.View_Type;
begin
v.Create(Main_View);
v.On_Double_Click_Handler(On_DoubleClick1'Unrestricted_Access);
v.Width(100);
v.Height(60);
v.Background_Color("Blue");
v.Border;
end On_Click1;
procedure On_Click2(Object : in out Gnoga.Gui.Base.Base_Type'Class) is
va : Gnoga.Gui.View.View_Access := new Gnoga.Gui.View.View_Type;
begin
va.Dynamic;
va.Create(Main_View);
va.On_Double_Click_Handler(On_DoubleClick1'Unrestricted_Access);
va.Width(100);
va.Height(60);
va.Background_Color("Red");
va.Border;
end On_Click2;
Clicks on the Blue area will give the message you see while clicks on
the Red area will work correctly. My guess is you have something
similar to the On_Click1 style, which won't work out.
