Method Detail

initialize

void initialize(long hwndHost)

Initialize the graphic container

Parameters:

hwndHost - The HWND of the hosting application

destroy

void destroy()

Destroy the graphic container

isRemoteManaged

boolean isRemoteManaged()

Return if the graphic container implements embedding styles and all management for window placement

On Windows this means to remove from the HWND: WS_CAPTION | WS_THICKFRAME | WS_MINIMIZEBOX | WS_MAXIMIZEBOX | WS_SYSMENU and add the child behavior using WS_CHILDWINDOW

Returns:

True if the graphic container implements embedding styles and management

setSizeAndVisibility

void setSizeAndVisibility(boolean isVisible,
                          int x,
                          int y,
                          int width,
                          int height)

Sets visibility and bounding rectangle

Parameters:

isVisible - Set visibility

x - The x-axis value of the left side of the rectangle.

y - The y-axis value of the top side of the rectangle.

width - A positive number that represents the width of the rectangle.

height - A positive number that represents the height of the rectangle.

hasMeasureOverride

boolean hasMeasureOverride()

Return if the graphic container implements management of MeasureOverride

Returns:

True if the object manages MeasureOverride

startMeasureOverride

void startMeasureOverride(int width,
                          int height)

Starts a MeasureOverride operation

Parameters:

width - The width constraint received

height - The height constraint received

getMeasureOverrideWidth

int getMeasureOverrideWidth()

MeasureOverride Width

Returns:

The width measured

getMeasureOverrideHeight

int getMeasureOverrideHeight()

MeasureOverride Height

Returns:

The height measured

endMeasureOverride

void endMeasureOverride()

End MeasureOverride operation

hasWndProcHandler

boolean hasWndProcHandler()

Return if the graphic container implements management for WndProc

Returns:

True if the object manages WndProc

wndProcHandler

boolean wndProcHandler(long hwnd,
                       int msg,
                       long wParam,
                       long lParam,
                       boolean handled)

Accesses the window process (handle) of the hosted child window

Parameters:

hwnd: - The window handle of the hosted window.

msg: - The message to act upon.

wParam: - Information that may be relevant to handling the message. This is typically used to store small pieces of information, such as flags.

lParam: - Information that may be relevant to handling the message. This is typically used to reference an object.

handled: - The handled value coming from the orginal call.

Returns:

True if the event was handled

hasFocusWithinCore

boolean hasFocusWithinCore()

Get focus state

Returns:

the focus state of the graphic container

getNativeWindowHandle

long getNativeWindowHandle()

Retrieves the native handle to the hosting window

Returns:

The native pointer

getGraphicObject

Object getGraphicObject()

The graphic Object hosted from the graphic container

Returns:

Object hosted
