Detailed Description

This class defines operations on a framed NX window. There are three instances that represent an NX window from the perspective of NXWidgets.

There is one widget control instance per NX window,
One CCallback instance per window,
One window instance.

There a various kinds of of window instances, but each inherits (1) CCallback and dispatches the Windows callbacks and (2) INxWindow that describes the common window behavior.

Constructor & Destructor Documentation

◆ CNxTkWindow()

CNxTkWindow::CNxTkWindow	(	NXHANDLE	hNxServer,
		CWidgetControl *	widgetControl
	)

Constructor. Creates an uninitialized instance of the CNxTkWindow object. The open() method must be called to initialize the instance.

The general steps to create any window include: 1) Create a dumb CWigetControl instance 2) Pass the dumb CWidgetControl instance to the window constructor that inherits from INxWindow. 3) The window constructor call CWidgetControl methods to "smarten" the CWidgetControl instance with window-specific knowledge. 4) Call the open() method on the window to display the window. 5) After that, the fully smartened CWidgetControl instance can be used to generate additional widgets. 6) After that, the fully smartened CWidgetControl instance can be used to generate additional widgets by passing it to the widget constructor

Parameters

hNxServer	Handle to the NX server.
widgetControl	Controlling widget for this window.

Constructor.

Parameters

hNxServer	Handle to the NX server.
widgetControl	Controlling widget for this window.

Member Function Documentation

◆ bitmap()

bool CNxTkWindow::bitmap	(	FAR const struct nxgl_rect_s *	pDest,
		FAR const void *	pSrc,
		FAR const struct nxgl_point_s *	pOrigin,
		unsigned int	stride
	)

virtual

Copy a rectangular region of a larger image into the rectangle in the specified window.

Parameters

pDest	Describes the rectangular on the display that will receive the bitmap.
pSrc	The start of the source image.
pOrigin	the pOrigin of the upper, left-most corner of the full bitmap. Both pDest and pOrigin are in window coordinates, however, pOrigin may lie outside of the display.
stride	The width of the full source image in bytes.

Returns: True on success; false on failure.

Copy a rectangular region of a larger image into the rectangle in the specified window. The source image is treated as an opaque image.

Parameters

pDest	Describes the rectangular on the display that will receive the bitmap.
pSrc	The start of the source image.
pOrigin	the pOrigin of the upper, left-most corner of the full bitmap. Both pDest and pOrigin are in window coordinates, however, pOrigin may lie outside of the display.
stride	The width of the full source image in bytes.

Returns: True on success; false on failure.

center	The window-relative coordinates of the circle center.
radius	The radius of the rectangle in pixels.
color	The color of the rectangle.

vector	- Describes the line to be drawn
width	- The width of the line
color	- The color to use to fill the line
caps	- Draw a circular cap on the ends of the line to support better line joins

pRect	The location to be filled.
color	The color to use in the fill.

pClip	Clipping rectangle relative to window (may be null).
pTrap	The trapezoidal region to be filled.
color	The color to use in the fill.

rect	The location to be copied
dest	- The describes the destination bitmap to receive the graphics data.

pRect	Describes the rectangular region to move.
pOffset	The offset to move the region.

CNxToolbar * CNxTkWindow::openToolbar	(	nxgl_coord_t	height,
		CWidgetControl *	widgetControl = `(CWidgetControl *)0`
	)

height.	The height in rows of the tool bar
widgetControl.	The controlling widget for this window. If none is provided, then a new, vanilla CWidgetControl will be created for the tool bar.

pos	The location of the pixel to be filled.
color	The color to use in the fill.
