|AHELP for CIAO 4.9 ChIPS v1||
Retrieves attribute value(s) for an object.
get_attribute([id,] object_type [,attribute])
The function arguments.
|id||A ChipsId structure identifying the item, or a string containing the name of the object.|
|object_type||The type of object to modify - e.g. chips_window, chips_curve, chips_line - as descrined in the Object Type section of "ahelp chipsopt".|
|attribute||The name of the attribute to retrieve, such as 'style' or 'line.color'.|
The get_attribute command retrieves the value of a specific attribute. If an attribute is not specified, the values of all attributes of the specified object are returned.
The command can only operate on a single object. An error is returned if currency is set to "all" and there are multiple versions of the object present.
Some values are set to "None" in the returned structure. These entries generally correspond to attributes which may only be modified at creation time, such as the object id.
chips> crv = get_attribute(chips_curve) chips> print(crv.symbol.color) default
Retrieve a structure containing the attribute values of the current curve and store the results in "crv". The print call is used to examine either one of the fields, as above, or the whole strtucture, as below:
chips> print(crv) baddata = 1 depth = 100 err.caplength = 10 err.color = default err.down = False ... symbol.fill = True symbol.size = 5 symbol.style = 4
chips> print(get_attribute("win1", chips_window, "display")) True
Retrieve the display attribute value for the window called "win1".
