Unreferenced date December 2009 ComponentLibrary for CrossPlatform CLX pronounced clicks , is a crossplatform visual component based framework for developing Microsoft Windows and Linux applications. It is developed by Borland for use in its Kylix programming tool Kylix , Delphi programming language Delphi , and C Builder software development environment. Its aim was to replace the popular Microsoft Windows only Visual ComponentLibrary , VCL. CLX was based on Qt framework Qt by Nokia . The Application programming interface API of CLX almost completely followed VCL. It was envisioned that existing applications using VCL would be recompiled with CLX. However, due to lacklustre performance on Windows, subtle differences from VCL, and bugs, it didn t become the expected successor to VCL. Commercial failure of Kylix stopped further development of CLX. In terms of object oriented approach, CLX forms an object hierarchy where the TObject class serves as the Superclass computer science base class . All other classes inherit or indirectly inherit the TObject class.

Crossplatform virtualization is a form of computer virtualization that allows software compiled for a specific CPU and operating system to run unmodified on computers with different CPUs and or operating systems, through a combination of dynamic binary translation and operating system call mapping. Since the software runs on a virtualized equivalent of the original computer, it does not require recompilation or porting , thus saving time and development resources. However, the processing overhead of binary translation and call mapping imposes a performance penalty, when compared to natively compiled software. For this reason, crossplatform virtualization may be used as a temporary solution until resources are available to port the software. Alternatively, crossplatform virtualization may be used to support legacy code, which running on a newer and faster machine still maintains adequate performance even with virtualization overhead. By creating an abstraction layer capable of running software compiled for a different computer system, crossplatform virtualization characterizes the Popek and Goldberg virtualization requirements outlined by Gerald J. Popek and Robert P. Goldberg in their 1974 article Formal Requirements for Virtualizable Third Generation Architectures ref cite journal author Gerald J. Popek and Robert P. Goldberg title Formal Requirements for Virtualizable Third Generation Architectures journal Communications of the ACM year 1974 volume 17 issue 7 pages 412 &ndash 421 url http doi.acm.org 10.1145 361011.361073 doi 10.1145 361011.361073 ref .

As well as built in Flash files, components can include both graphics and code. Self contained functionality of Flash components enables to easily integrate the file into any project. For example, a component can be a scroll bar, a site form, a gallery, or even something that has no graphics at all, such as a timer, a server connection utility, or a custom XML parser.

In mathematics , the identity component of a topological group G is the connected component topology connected component G sub 0 sub of G that contains the identity element of the group. Similarly, the identity path component of a topological group G is the path component of G that contains the identity element of the group. Properties The identity component G sub 0 sub of a topological group G is a closed set closed , normal subgroup of G . It is closed since components are always closed. It is a subgroup since multiplication and inversion in a topological group are continuous map topology continuous map s by definition. Moreover, for any continuous automorphism a of G we have a G sub 0 sub G sub 0 sub . It follows that G sub 0 sub is normal in G . The identity component G sub 0 sub of a topological group G need not be open set open in G . In fact, we may have G sub 0 sub e , in which case G is totally disconnected group totally disconnected . However, the identity component of a locally path connected space for instance a Lie group is always open, since it contains a path connected neighbourhood of e and therefore is a clopen set . The identity path component may in general be smaller than the identity component since path connectedness is a stronger condition than connectedness , but these agree if G is locally path connected. Component group The quotient group G G sub 0 sub is called the group of components or component group of G . Its elements are just the connected components of G . The component group G G sub 0 sub is a discrete group if and only if G sub 0 sub is open. If G is an affine algebraic group then G G sub 0 sub is actually a finite group . One may similarly define the path component group as the group of path components quotient of G by the identity path component , and in general the component group is a quotient of the path component group, but if G is locally path connected these groups agree. The path component group can also be characterized as the zeroth ... more details
