* Name: nxtk_drawlinewindow
|
||||
*
|
||||
* Description:
|
||||
* Fill the specified line in the window with the specified color. This
|
||||
* is simply a wrapper that uses nxgl_splitline() to break the line into
|
||||
* trapezoids and call calls nxtk_filltrapwindow() to render the line.
|
||||
*
|
||||
* Input Parameters:
|
||||
* hfwnd - The window handle returned by nxtk_openwindow
|
||||
* vector - Describes the line to be drawn
|
||||
* width - The width of the line
|
||||
* color - The color to use to fill the line
|
||||
*
|
||||
* Return:
|
||||
* OK on success; ERROR on failure with errno set appropriately
|
||||
