在RFT中根据指定的标题查找顶层窗口

在RFT中提供了丰富的底层接口（如IWindow），可以让我们实现很多底层的对象操作，例如根据给定的标题查找顶层窗口：

IWindow window = getTopWindowWithCaption( "计算器" , true );

if (window != null )

{

window.activate();

window.close();

}

IWindow[] windows = getTopWindowsWithCaptionPattern( ".*记事本" , true );

if (windows!= null )

{

for ( int i=0;i<windows. length ;i++)

{

windows[i].activate();

windows[i].close();

}

}

getTopWindowWithCaption函数如下，其作用是根据给定的标题（Caption）查找顶层窗口，返回第一个找到的窗口：

/**

* Given the expected caption find a top level window that has that caption.

* The first window found with the caption is returned.

*

* @param caption The caption of the desired window.

* @param ignoreCase Flags if case i significant in the caption comparisons.

* @return The first top level window with the specified text that is located.

*/

protected IWindow getTopWindowWithCaption(String caption, boolean ignoreCase)

{

if ( caption == null )

caption = "" ;

IWindow[] topWindows = getTopWindows ();

int length = ( topWindows != null ? topWindows. length : 0 );

for ( int i = 0; i < length; ++i )

{

String text = topWindows[i].getText();

if ( ( !ignoreCase && caption.equals(text) ) ||

( ignoreCase && caption.equalsIgnoreCase(text) ) )

return topWindows[i];

}

return null ;

}

函数中的getTopWindows方法将返回当前系统中的所有窗口对象。

getTopWindowsWithCaptionPattern函数如下，支持正则表达式给定Caption，返回所有匹配的窗口对象。

/**

* Given the expected caption pattern find all top level windows that have a caption

* that matches the pattern. Basically if the pattern is "^Notepad - " all top level

* windows that have a caption that starts with "Notepad - " will be returned.

*

* @param pattern The caption pattern of the desired windows.

* @param ignoreCase Flags if case is significant in the caption pattern matches.

* @return The set top level windows with the specified caption text pattern.

*/

protected IWindow[] getTopWindowsWithCaptionPattern(String pattern, boolean ignoreCase)

{

Regex regex = ( ignoreCase ? new Regex(pattern, Regex. MATCH_CASEINDEPENDENT ) :

new Regex(pattern) );

java.util.Vector matches = new java.util.Vector(10);

IWindow[] topWindows = getTopWindows ();

int length = ( topWindows != null ? topWindows. length : 0 );

for ( int i = 0; i < length; ++i )

{

String text = topWindows[i].getText();

if ( regex.matches(text) )

matches.add(topWindows[i]) ;

}

int resultLength = matches.size();

IWindow[] result = ( resultLength != 0 ?

new IWindow[resultLength] :

null );

for ( int i = 0; i < resultLength; ++i )

result[i] = (IWindow)matches.elementAt(i);

return result;

}
