GraphicCompTool(3U) InterViews Reference Manual GraphicCompTool(3U)NAME
GraphicCompTool - tool for instantiating graphical components
SYNOPSIS
#include <Unidraw/Tools/grcomptool.h>
DESCRIPTION
A GraphicCompTool lets the user instantiate graphical components by direct manipulation. The GraphicCompTool keeps a prototypical compo-
nent that defines the type of component it can instantiate.
PUBLIC OPERATIONS
GraphicCompTool(ControlInfo*, GraphicComp* prototype)
GraphicCompTool()
Create a new GraphicCompTool, supplying the prototypical GraphicComp. (You should not normally call the parameterless constructor,
which Creator requires.) The first constructor creates a graphical view of the prototype for internal use.
virtual Manipulator* CreateManipulator(
Viewer*, Event&, Transformer*
)
virtual void InterpretManipulator(Manipulator*)
CreateManipulator clears the editor's selection and delegates manipulator creation and interpretation to the graphical view of the
prototype.
GraphicComp* GetPrototype()
Return the prototypical GraphicComp.

RectComp(3U) InterViews Reference Manual RectComp(3U)NAME
RectComp, RectView, PSRect - rectangle component subject, view, and PostScript external representation
SYNOPSIS
#include <Unidraw/Components/rect.h>
DESCRIPTION
RectComp is a GraphicComp that defines a rectangle. It uses an SF_Rect graphic to store its graphical attributes. RectView is a Graph-
icView for displaying the rectangle. PSRect is a PostScriptView that externalizes the subject's information in PostScript form.
RECTCOMP PUBLIC OPERATIONS
RectComp(SF_Rect* = nil)
The constructor takes an optional stroked-filled rectangle that defines the attributes of the rectangle.
SF_Rect* GetRect()
Return the SF_Rect graphic that defines the rectangle's attributes. GetRect is simply a more specific form of the GetGraphic opera-
tion.
RECTVIEW PUBLIC OPERATIONS
RectView(RectComp* = nil)
Create an RectView, optionally supplying the subject.
virtual void Interpret(Command*)
RectView interprets AlignToGridCmd to align its lower-left to the grid.
virtual Manipulator* CreateManipulator(
Viewer*, Event&, Transformer*, Tool*
)
virtual void InterpretManipulator(Manipulator*)
RectView redefines its response to manipulation with a GraphicCompTool. GraphicCompTool will let the user sweep out a rectangle that
reflects the RectComp's size. Creation will be influenced by gravity, if any. RectView also defines a response to the ReshapeTool,
allowing the user to click on one of its corners to reposition it. The subject is actually replaced (via ReplaceCmd) with a Poly-
gonComp subject reflecting the repositioned corner. Repositioning will be influenced by gravity.
virtual void GetCorners(Coord*, Coord*)
GetCorners takes two arrays of four Coord values and stores into them the coordinates of its corners, in canvas coordinates.
RectComp* GetRectComp()
Return the subject.
RECTVIEW PROTECTED OPERATIONS
virtual void CreateHandles()
RectView redefines CreateHandles to use a RubberHandles object with four handles, one at each corner of the rectangle.
PSRECT PUBLIC OPERATIONS
PSRect(RectComp* = nil)
Construct a PostScript external representation of the given subject, if any.

I have seen some misinformation regarding Unix file permissions. I will try to set the record straight. Take a look at this example of some output from ls:

sort -nr --key=1 ....

Suppose I have a main() function with only one malloc statement allocating say some 1 gb memory. Also say my system has 1 gb of ram.
main()
{
malloc(1gb)
return(0)
}
The program above exits without freeing the memory.
In this case will the 1 gb of heap memory be returned... (9 Replies)

Hey All,
Quick question...
I'm writing a short script to check if a continuous port is running on a server.
I'm using "ps -ef | grep -v grep | grep processName" and I was wondering if it was better/more reliable to just check the
return code from the command or if its better to pipe to... (12 Replies)
I installed NetBSD 6.1.2 amd64 and can't find the apm utility. Is it not in the base system?
Is it necessary to recompile the default amd64 kernel to use apm?
Or is there a new method for power management and suspend/resume? (2 Replies)
Hi,
I am learning shell scripting for the first time. I use AT&T Korn Shell, Version AJM 93u+ 2012-08-01, compiled from source on NetBSD.
So far I have managed to set up what I think is a useful and pleasing shell prompt, which can be seen in the image attached to this post.

Hey gang, I have a list of times I need to sum up. This list can vary from a few to a few thousand entries.

Usually when I on the evening go to bed I take some interesting book with me. I read it for a while to get me down to sleep. Probably most people seek information from the Nett by googleing but I am so oldfashioned I prefer a real book ;)
