Styles ?

[sagent100]

Hi,
As you may be can see, I am new using shapes files!
The question is, when we create a new object using shapelib, where is it possible to set the styles ?
For example if i am creating a point, where can we define the fontname, size, color, angle, etc ?
Or creating a line, the style (dash, dot, single, etc), color, size, etc
Or creating a poligon, the brush, background color, border style, border size, etc.

Thank you!

The shapefile contains the geometry not the attributes such as those you
describe.  In general this type of editing is performed in the application
displaying the shapefile.  If you wanted to set these attributes, you would
use a format such as ESRI's layer file (.lyr).  

Hope this helps.

You could always define this in the DBF file.....

Thank you for your help !
As you told me, the .shp file have only geometries, not styles.
So the question is, using shapelib, how the .lyr is created ?, or how can I tell which style have each object?

Which is the default style shapelib use for each kind of object when I create a new one using the library?

As I understand you say I have to open the table with ArcView f.e and change the styles there. Is it true?

Thank you !!!

sagent100,

Shapelib includes no support for .lyr files. The are another whole ball of
wax.  You can use shapelib to attach attributes to features (shapes)
via the dbf api that could later be used as a basis of style classification
in a .lyr file but the attribute concept is generic, not only for styling.

I believe to create .lyr files you would need to either do it interactively
in ArcView or use the ESRI provided scripting/programing libraries to
manipulate the .lyr file.

Good luck,
