Is there any possibility to use swing component in zul?
I want to display a text file in a textarea (e.g. JTextArea). The problem with Zkoss Textbox is, that it doesn't have append() method like JTextArea has. This is a problem, because the string that will be display, is only the last line of the file.
public void displayOutput(){
String line2;
String x = null;
try{
final Listbox listbox = (Listbox)this.getFellow("items");
final Textbox tboutput = (Textbox)this.getFellow("outputviewer");
Listitem lt = listbox.getSelectedItem();
String path = ((de.qcdb.lmu.domain.Item)lt.getValue()).getFilepath();
BufferedReader in = new BufferedReader(new InputStreamReader(new FileInputStream("/root/workspace/QCDB/WebContent"+path)));
while((line2 = in.readLine()) != null){
x = line2;
tboutput.setValue(x);
}
}
catch (IOException e){
e.printStackTrace();
}
}
Source CodeThanx in advance
Nope it isn't :-) I guess you do not understand much how ZK works. Anyway, you may use <textbox rows="20" />. Also, the code is wrong:
while((line2 = in.readLine()) != null){
x = line2;
tboutput.setValue(x);
}
it will always display the last line, does not matter what king of widgets you use.
You can use a StringBuilder to collect all the textfile lines and the show them all in a ZK text component. Say
StringBuilder sb = new StringBuilder(2048);
while((line2 = in.readLine()) != null){
sb.append(line2);
}
tboutput.setValue(sb.toString());
Wow it works, thanks a lot for the tips guys,
The textbox I used, have already 40 rows, but the problem is that zkoss doesn't have a kind of JTextArea, which has the method append.
The only way I knew before is converting every new lines with a specific string and write into a file with single line. Then read again this file and convert it again into newlines. But this reduce the efficiency and consumes more time.
The StringBuilder is really kool. I didn't know there's is this kool class.
Thanx
