Abstract
Abstract Apparatus for specifying invocations in compiled objects at runtime. One species of the apparatus is a drawing widget for use in the X Window System. The drawing widget permits users to specify elements in the window corresponding to the widget by providing a sequence of invocations of X Window graphics functions to the widget at runtime. A resource in the drawing widget is set to the sequence of invocations and when the corresponding window is exposed, the invocations in the sequence are executed to produce the elements in the window. The sequence of function invocations may include invocations for functions which add or remove elements from the window and which translate, rotate, or scale elements. Other features include the use of unit coordinates in the invocation and the use of hashing to reduce the character-string invocations provided in the sequence to representations made up of small integer, pointer, and floating-point data.

Claims Analysis
Total Claims: 28
Claim 1
Independent Claim
93 words
A widget contained in memory means usable in a computer system that is implementing a windowing system, the widget representing a window displayed in the windowing system and the widget comprising: means which when executed in the computer system at runtime set a resource of the widget to one or more invocations of arbitrary functions of a set thereof; and means which when executed in the computer system in response to a change in the widget employ the invocation to execute a function of the set of arbitrary functions specified in the invocation.
Claim 2
Dependent Claim
93 words
A widget contained in memory means usable in a computer system that is implementing a windowing system, the widget representing a window displayed in the windowing system and the widget comprising: means which when executed in the computer system at runtime set a resource of the widget to one or more invocations of arbitrary functions of a set thereof; and means which when executed in the computer system in response to a change in the widget employ the invocation to execute a function of the set of arbitrary functions specified in the invocation.

Claim 8
Dependent Claim
52 words
The widget set forth in any of claims 1 , 2 , 3 , 4 , or 5 wherein: the means which set the resource orders the invocations to which the resource is set; and the means which employ the invocation executes the invocations to which the resource is set as ordered.
Claim 9
Dependent Claim
71 words
The widget set forth in any of claims 1 , 2 , 3 , 4 , or 5 wherein: the one or more invocations include character string data; the means which set the resource further includes means for translating the character string data into data of another type; and the invocations to which the resource is set include the data of the other type in place of the character string data.
Claim 10
Dependent Claim
19 words
The widget set forth in claim 1 wherein: the functions include graphics primitive functions provided by the windowing system.
Claim 11
Dependent Claim
54 words
The widget set forth in claim 9 wherein: the invocations of the graphics primitive functions include arguments specifying coordinates according to a first system; and the means which employ the invocation includes means for changing the arguments so that the arguments specify coordinates according to a second system required for the graphics primitive functions.
Claim 12
Dependent Claim
44 words
The widget set forth in claim 9 wherein: the functions include transformation functions; and the means which employ the invocation includes means for transforming the arguments in the invocations of the graphics primitive functions, the means for transforming being responsive to the transformation functions.
Claim 13
Dependent Claim
22 words
The widget set forth in claim 11 wherein: the transformation functions include a rotation function, a translation function, and a scaling function.
Claim 14
Dependent Claim
52 words
The widget set forth in claim 11 wherein: the invocations of the graphics primitive functions include arguments specifying coordinates according to a first system; and the means for transforming includes means for changing the arguments so that the arguments specify coordinates according to a second system required for the graphics primitive functions.
Claim 15
Dependent Claim
21 words
The widget set forth in claim 11 wherein: the means for transforming is further responsive to any resizing of the window.
Claim 16
Dependent Claim
40 words
The widget set forth in claim 9 wherein: the means which employ the invocation includes means responsive to any resizing of the window for transforming the arguments in the invocations of the graphics primitive functions as required by the resizing.
Claim 17
