The group of TA libraries appears like this:
Produce DWGs Like It’s 2016: Teigha For Architecture
Essentially, they are regular Home windows DLL files (you may also build software development Malaysia for other platforms: iOS, Linux, UNIX, etc.). You’ll find LIB files for these questions separate folder. Additionally to TA, we’ll require the Teigha Core libraries, because TA is definitely an extension on the top from the Core objects. Core implements the primary systems and objects from the original AutoCAD.
Initializing ?eigha Architecture
To initialize the library, we want a category that performs platform-specific procedures on files.
class MyServices : public ExSystemServices, public ExHostAppServices
The distribution package incorporates two ready-made extensions for Home windows, ExSystemServices and ExHostAppServices, which we are able to use within this situation. Then we have to initialize the library and also the graphics subsystem:
_OdStaticRxObject_ adds the _addRef/Release_ logic for an object. The library saves the mention of MyServices object and uses that object for platform-specific procedures.
AecBase, AecArchBase, etc. would be the Texas modules (that’s, DLL libraries) proven within the screenshot above. Software development Malaysia have been linked using LIB files, but that’s insufficient. We should also initialize them as modules. Exactly what does it mean? At runtime, the memory consists of a dictionary of loaded classes. The dictionary enables you to definitely cast references between various kinds of TA objects and make cases of TA classes using a centralized pseudo-constructor mechanism.
For instance, once the command ::odrxDynamicLinker()->loadApp( OD_T(“AecArchBase”) ) has been performed, the part AECArchBase::initApp() is going to be known as within the framework. Essentially, initApp() will register all classes from the library within the global dictionary by calling the static function rxInit() for all of them:An AEC dictionary is produced within the database. That dictionary consists of the default measurement models for length, area, volume, and position, in addition to print configurations. Display representations implemented within the modules are registered.
The initialization is finished. For those who have skipped some steps, the end result is determined by which step you skipped: Objects won’t be produced or won’t be made (you will notice a clear screen), or there might be other glitches.
