Member Function Documentation

void OutputStreamArea::capture (    )  [inline]
 

capture redirects all the output to the TextArea.

This method is helpful when an OutputStreamArea is created and you wait till the containing frame is shown to redirect the output (in the meantime all the output goes to the console). 

00065 {
00066     _theOutput = this;
00067 }

void OutputStreamArea::actionPerformed (  ActionEvent    e )  [inline]
 

Implementation of ActionListener. 

00072 {
00073     if (e.getSource() == _bClear)
00074         doClear();
00075 }

void OutputStreamArea::print (  String    str )  [inline, static]
 

Displays the given string (without printing a newline). 

00081 {
00082     if (_theOutput != null)
00083         _theOutput.doPrint(str);
00084     else
00085         System.out.print(str);
00086 }

void OutputStreamArea::println (  String    str )  [inline, static]
 

Displays the given string and a newline. 

00092 {
00093     if (_theOutput != null)
00094         _theOutput.doPrintln(str);
00095     else
00096         System.out.println(str);
00097 }

void OutputStreamArea::clear (    )  [inline, static]
 

Clears the output area. 

00103 {
00104     if (_theOutput != null)
00105         _theOutput.doClear();
00106 }

native void OutputStreamArea::initGuiOutputStream (    )  [protected]
 

Reimplemented in AppletOutputStreamArea.

void OutputStreamArea::doPrint (  String    str )  [inline, protected]
  

00112 {
00113     _text.append(str);
00114 }

void OutputStreamArea::doPrintln (  String    str )  [inline, protected]
  

00117 {
00118     _text.append(str + "\n");
00119 }

void OutputStreamArea::doClear (    )  [inline, protected]
 

Reimplemented in AppletOutputStreamArea.

00123     _text.setText("");
