I have a Checkbutton in a dialog.
In some cases I don't want to see that Checkbutton, because the program will
prohibit the calulation that Checkbutton is needed for.
I found the method Set_Visible for the Checkbutton and applied it I was
under the inpression that when I used Show_all for that dialog I would not
see the Checkbutton (with false as parameter).
But the Checkbutton could be used and it even could be check with some Error
as result.
What do I have to do to just hide only the Checkbutton in the Dialog

Gtk.Widget:
procedure Hide (Widget : not null access Gtk_Widget_Record);

Pitty I just replaced Set_Visible(false) by Hide and nothing happened
The problem stays the same

Just for information.
I Use Show_All for showing the dialog. When I use Show for the Dialog this
means that other parts of the dialog also disappear.
Does that mean that I have to show all elements within the dialog apart

Show_All recursively calls Show for the widget and all its children.

No, it means that only the given widget is shown, the dialog itself is
in this case.
> Does that mean that I have to show all elements within the dialog apart
This is what Show_All does. Hide is to reverse Show. If that does not
work, it means you called it too early or on a wrong widget.
BTW, another techniques are:
1. Remove/add children to the container as they needed, dynamically.
2. Use Set_Sensitive to gray the widget out, leaving it visible.
The second method is preferable when the user must see all possibilities
or when the widget layout must be preserved.
