long          Flag

This flag control the appearance of the tool.

Some of the bits are common to all tolls:

OUTIL_INVISIBLE          // no graphics

OUTIL_DISABLE          // no select (but graphics OK)

OUTIL_VERTICAL

OUTIL_EMPTY          // no fill

OUTIL_OUTLINE          // border as blue outline

OUTIL_NO_3D          // flat fill

OUTIL_NO_BORDER          // do not draw the outside box

OUTIL_OUT =          (OUTIL_DISABLE|OUTIL_INVISIBLE|OUTIL_OUTLINE)

and others are specific for certain tools (they will be discussed in each tool's sections.)

char * Name

This variable contain the name of the tool.  It can be NULL if no name is to be displayed.  If you do specify a name, you can assign it directly to the variable, or use the SetName method.  Be sure to allow enough space to display the name when you specify the dimensions of the tool.  The position of the name inside the tool can sometime be modified with the flag values:

NAME_V_CENT

NAME_TOP

NAME_BOTTOM

NAME_H_CENT

NAME_LEFT

NAME_RIGHT

short          Pos_X

short          Pos_Y

short          Dim_X

short          Dim_Y

These variables control the position and size of the tool within the window.  0,0 is at the bottom left corner of the window.

short          border

This variable control the size of the border of the tool.  The border size used by sliceO-5 can be found in the variable $INTERFACE_BORDER_DIM

char          *Name

char          *Font_Name

char          *Font_Weight

char          *Font_Slant

short           Font_Scale

These variable give a name to the tool and control the appearance of that name.  In sliceO-5, these values are found in the variables: "$INTERFACE_TITLE_FONT_NAME", "$INTERFACE_TITLE_FONT_WEIGHT", "$INTERFACE_TITLE_FONT_SCALE"

for the title of the modes and tools, and in "$INTERFACE_TOOL_FONT_NAME", "$INTERFACE_TOOL_FONT_WEIGHT", "$INTERFACE_TOOL_FONT_SCALE" for the tool's fonts,

Colors           color

This variable give the color of the tool. The "Colors" class is described here.

short          clip_x

short          clip_y

short          clip_h

short          clip_w

These optional variables are used to limit the drawing area of the tool.  They are useful if the graphic window is smaller than the space needed to draw the tool. We will usually use the window's dimensions for the clip values.

unsigned long *Graph_Select

unsigned long *Graph_Normal

These variable contain pointers to the pixel data needed to fill the tool when it is selected and when it is not.  The pixel data is RGB values stored in 32 bits integers. If you do not override these pointers with your own image data, the default background it will be created during the "Init" method.
