Detailed Description

Class Interface.

Description:

This the base class for the creation of non-3D windows that appear in a 3ds Max viewport. These views are called "Extended Viewports". In order for a window to appear inside a viewport, you need to derive a class from this class. An instance of the derived class must be registered via the RegisterViewWindow() call in the Interface class. A given ViewWindow derivative should only be registered once.

When developers have registered their window types, the list of available extended views will appear in the view selection pop-up (either in the right-click viewport menu or the Viewport Configuration dialog) as a submenu of the "Extended" view label.

There are two items which should be made in the extended viewport dialog proc code:

Interface::MakeExtendedViewportActive() should be called whenever the user clicks in the non-3D window (so as to deactivate the current 3D window, and redirect commands like the Min/Max toggle to the non-3D viewport window).

Interface::PutUpViewMenu() should be called when the user right-clicks in a dead region of the non-3D window. This brings up the view selection menu so that the user can choose to replace the current window with a 3D or other non-3D window without having to go to the Views | Viewport Config dialog directly.

All methods of this class are virtual.

Sample Code:

class TestViewWindow : public ViewWindow
{
 
    const MCHAR *GetName() { return _M("TestViewWindow"); }
    HWND CreateViewWindow(HWND hParent, int x, int y, int w, int h);
    void DestroyViewWindow(HWND hWnd);
};
 
HWND TestViewWindow::CreateViewWindow(HWND hParent, int x, int y, int w, int h)
{
    return CreateWindow("button", "Test Button", WS_VISIBLE | WS_CHILD, x, y, w, h, hParent, NULL, (HINSTANCE)GetWindowLong(hParent, GWL_HINSTANCE), NULL);
}
 
void TestViewWindow::DestroyViewWindow(HWND hWnd)
{
    DestroyWindow(hWnd);
}
 
static TestViewWindow tvw;

Member Function Documentation

GetName()

virtual const MCHAR * GetName ( )

pure virtual

Remarks

Returns the name of the window type. For example, "Asset Manager".

Implemented in ListenerViewWindow.

CreateViewWindow()

virtual HWND CreateViewWindow ( HWND  hParent, int  x, int  y, int  w, int  h  )

pure virtual

Remarks

Creates and returns a handle to a new extended view window.

Parameters:

HWND hParent

The handle of the parent window.

int x

The x coordinate of the window's upper left corner.

int y

The y coordinate of the window's upper left corner.

int w

The window width.

int h

The window height.

Implemented in ListenerViewWindow.

DestroyViewWindow()

virtual void DestroyViewWindow ( HWND  hWnd )

pure virtual

Remarks

Destroys the previously created window as specified by the handle.

Parameters:

HWND hWnd

The handle of the window to destroy.

Implemented in ListenerViewWindow.

CanCreate()

virtual BOOL CanCreate ( )

inlinevirtual

Remarks

Returns TRUE if the ViewWindow can be created; otherwise FALSE. This method can be overridden to return FALSE if a ViewWindow can only have a single instance, and that instance is already present. If this method returns FALSE, then the menu item for this ViewWindow will be grayed out.

Default Implementation:

{ return TRUE; }

Reimplemented in ListenerViewWindow.

{ return TRUE; }

NumberCanCreate()

virtual int NumberCanCreate ( )

inlinevirtual

Remarks

This method returns the number of instances of a given window that can be created. This allows, for example, the UI to know without physically creating a window that only a limited number of windows of that type can be created. A -1 implies that the count is not known.

Default Implementation:

{ return -1; }

{ return -1; }

GetMetaData()

virtual ViewWindowMetaData GetMetaData ( )

pure virtual

Implemented in ListenerViewWindow.

ClassID()

virtual Class_ID ClassID ( ) const

pure virtual

Implemented in ListenerViewWindow.
