XtUnmanageChildren
Xt - Geometry Management

### XtUnmanageChildren

remove a list of children from a parent widget's managed list.
4 March 1996

    void XtUnmanageChildren(children, num_children)
        WidgetList children;
        Cardinal num_children;

#### Inputs

children

  Specifies an array of child widgets. Each child must be of class RectObj or any subclass thereof.

num_children

  Specifies the number of elements in children.

#### Description

`XtUnmanageChildren()` unmaps the specified widgets and removes them from their parent's geometry management. The widgets will disappear from the screen, and (depending on its parent) may no longer have screen space allocated for them.

Each of the widgets in the children array must have the same parent.

See the “Algorithm” section below for full details of the widget unmanagement procedure.

#### Usage

Unmanaging widgets is the usual method for temporarily making them invisible. They can be re-managed with `XtManageChildren()`.

You can unmap a widget, but leave it under geometry management by calling `XtUnmapWidget()`. You can destroy a widget's window without destroying the widget by calling `XtUnrealizeWidget()`. You can destroy a widget completely with `XtDestroyWidget()`.

If you are only going to unmanage a single widget, it is more convenient to call `XtUnmanageChild()`. It is often more convenient to call `XtUnmanageChild()` several times than it is to declare and initialize an array of widgets to pass to `XtUnmanageChildren()`. Calling `XtUnmanageChildren()` is more efficient, however, because it only calls the parent's `change_managed()` method once.

#### Algorithm

`XtUnmanageChildren()` performs the following:

-

  Ignores the child if it already is unmanaged or is being destroyed.

-

  Otherwise, if the child is realized, it makes it nonvisible by unmapping it.

#### Structures

The WidgetList type is simply an array of widgets:

    typedef Widget *WidgetList;

You silly goose! Check out the Commands Section for the answer.

Why can't I twiddle my documents?

You can only twiddle your documents if you have the foobar.lib installed.
