# wxMDIClientWindow(3erl)

Functions for wxMDIClientWindow class

## NAME

wxMDIClientWindow - Functions for wxMDIClientWindow class

## DESCRIPTION

An MDI client window is a child of *wxMDIParentFrame*, and manages zero or more *wxMDIChildFrame* objects.

The client window is the area where MDI child windows exist. It doesn't have to cover the whole parent frame; other windows such as toolbars and a help window might coexist with it. There can be scrollbars on a client window, which are controlled by the parent window style.

The *wxMDIClientWindow* class is usually adequate without further derivation, and it is created automatically when the MDI parent frame is created. If the application needs to derive a new class, the function *wxMDIParentFrame::OnCreateClient()* (not implemented in wx) must be overridden in order to give an opportunity to use a different class of client window.

Under wxMSW, the client window will automatically have a sunken border style when the active child is not maximized, and no border style when a child is maximized.

See: *wxMDIChildFrame*, *wxMDIParentFrame*, *wxFrame*

This class is derived (and can use functions) from: *wxWindow* *wxEvtHandler*

wxWidgets docs: wxMDIClientWindow

## DATA TYPES

```
wxMDIClientWindow() = wx:wx_object()
```

## EXPORTS

```
new() -> wxMDIClientWindow()
```

Default constructor.

Objects of this class are only created by *wxMDIParentFrame* which uses the default constructor and calls *createClient/3* immediately afterwards.

```
createClient(This, Parent) -> boolean()
```

Types:

This = wxMDIClientWindow()\
 Parent = wxMDIParentFrame:wxMDIParentFrame()\

```
createClient(This, Parent, Options :: [Option]) -> boolean()
```

Types:

This = wxMDIClientWindow()\
 Parent = wxMDIParentFrame:wxMDIParentFrame()\
 Option = {style, integer()}\

Called by *wxMDIParentFrame* immediately after creating the client window.

This function may be overridden in the derived class but the base class version must usually be called first to really create the window.

```
destroy(This :: wxMDIClientWindow()) -> ok
```

Destroys the object.
