OBJECT ARX 总结5

转自：http://apps.hi.baidu.com/share/detail/30275499#content

1.     系统变量查询与设置，暂停使用户输入，与AutoCAD的参数传递（acedCommand）等；

acedSetVar：设置系统变量

acedGetVar：获取系统变量值 

result = acedCommand(RTSTR, "Zoom", RTSTR, PAUSE, RTNONE); //使用PAUSE暂停，让用户输入

result = acedCommand(RTSTR, "circle", RTSTR, "5,5", RTSTR, PAUSE, RTSTR, "line", RTSTR, "5,5", RTSTR, "7,5", RTSTR, "", 0);  

acedInvoke：调用其它ARX注册的外部函数

acedCommond：调用全局命令

2.     获取用户输入函数；

函数名	功能
acedGetInt	获取一个整数
acedGetReal	获取一个浮点
acedGetDist	获取一个距离
acedGetAngle	获取一个角度
acedGetOrient	获取一个方向角
acedGetPoint	获取一个点
acedGetCorner	获取矩形的对角点
acedGetKword	获取用户输入的关键字
acedGetString	获取字符串

ads_usrbrk取消命令如何使用？

对于acedGetString的获取的各种字符如何处理？

3.     类型转换函数；

acdbRToS()             converts a real value, an angle to string values

acdbAngToS()

acdbDisToF()           convert strings back into real (distance) values or angles

acdbAngToF()

4.     字符处理函数；

acutIsAlpha	Verifies that the character is alphabetic
acutIsUpper	Verifies that the character is uppercase
acutIsLower	Verifies that the character is lowercase
acutIsDigit	Verifies that the character is a digit
acutIsXDigit	Verifies that the character is a hexadecimal digit
acutIsSpace	Verifies that the character is a white-space character
acutIsPunct	Verifies that the character is a punctuation character
acutIsAlNum	Verifies that the character is alphanumeric
acutIsPrint	Verifies that the character is printable
acutIsGraph	Verifies that the character is graphical
acutIsCntrl	Verifies that the character is a control character
acutToUpper	Converts the character to uppercase
acutToLower	Converts the character to lowercase

5.     坐标变换函数；

acutCvUnit()            takes a value expressed in one system of units and returns the equivalent value in another system

acedTrans()             function translates a point or a displacement from one coordinate system into another

6.     显示控制函数；

acedPrompt              displays a message on the AutoCAD prompt line

acutPrintf()            displays text on the text screen.

acdbFail()              displays messages on the text screen

acedMenuCmd()           provides control of the display of the graphics screen menu

acedGraphScr()          display the graphics screen

acedTextScr()           display the text screen

acedTextPage()          like acedTextScr(), but it clears the text screen before displaying it (as the AutoCAD STATUS   command does)

acedRedraw()            similar to the AutoCAD REDRAW command

acedGrDraw()

acedGrVecs()

7、图形交互函数。

acedTablet()

acutWcMatch()
