[izpack-users] Simple question about PathInputPanel

[Bartz, Klaus]

Hi Christopher,
the messages for labels are stored in 
%IZ_HOME%\bin\langpacks\installer\<iso3>.xml
or in your custom lang pack file(s).
Create entries using your class name for the keys:
 
    <str id="DataPathPanel.intro" txt="A multi line text."/>
    <str id="DataPathPanel.info" txt="The text in the label "/>
    <str id="DataPathPanel.empty_target" txt="The text which will be
placed in a message box if target not exists."/>
    <str id="DataPathPanel.warn" txt="The text which will be placed in a
message box if target exits."/>
For more see the entries for TargetPanel and PathInputPanel.
For summary add
    <str id="DataPathPanel.summaryCaption" txt="Data path path"/>
The headline text put also in the langpack, not the java source.
    <str id="DataPathPanel.headline" txt="FUBAR headline"/>
For enabling headline see docu chapter "Modifying the GUI".
.
Cheers
 
Klaus

	I have extended the PathInputPanel to make a custom panel to
select a directory needed for my installation.
	The problem I am having is I cannot figure out how to set the
label on the panel.  The panel shows up but it looks like the default
target install panel.
	I am sure I am missing something simple, so any help would be
greatly appreciated.
	
	Here is my Java code:
	
	package com.izforge.izpack.panels;
	
	import javax.swing.JLabel;
	
	import com.izforge.izpack.installer.InstallData;
	import com.izforge.izpack.installer.InstallerFrame;
	
	/**
	 * Input panel for the data path.
	 *
	 */
	public class DataPathPanel extends PathInputPanel {
	
	    /**
	     *  The constructor.
	     *
	     * @param  parent  The parent window.
	     * @param  idata   The installation data.
	     */
	    public DataPathPanel(InstallerFrame parent, InstallData
idata) {
	        super(parent, idata);
	        headline = "FUBAR headline";
	        headLineLabel = new JLabel ("FUBAR headlinelabel");
	    }
	
	    /**
	     *  Indicates whether the panel has been validated or not.
	     *
	     * @return    Whether the panel has been validated or not.
	     */
	    public boolean isValidated() {
	        if (!super.isValidated())
	            return (false);
	        System.out.println ("isValidated");
	        String chosenPath = pathSelectionPanel.getPath();
	        if (chosenPath == null || chosenPath.length() < 1)
	            return (false);
	        idata.setVariable("DATA_DIRECTORY", chosenPath);
	
	        return (true);
	    }
	
	    /* (non-Javadoc)
	     * @see com.izforge.izpack.installer.IzPanel#panelActivate()
	     */
	    public void panelActivate() {
	        super.panelActivate();
	        // Resolve and set the default for chosenPath
	        String chosenPath;
	        // common lines for back steps...
	        if (idata.getVariable("DATA_DIRECTORY") != null)
	            chosenPath = idata.getVariable("DATA_DIRECTORY");
	        else
	            chosenPath = idata.getInstallPath();
	        pathSelectionPanel.setPath(chosenPath);
	    }
	
	    /* (non-Javadoc)
	     * @see
com.coi.tools.install.panels.SummaryPanelClient#getSummaryBody()
	     */
	    public String getSummaryBody() {
	        return (String) (idata.getVariable("DATA_DIRECTORY"));
	    }
	}
	
	And here is my install file:
	
	<?xml version="1.0" encoding="iso-8859-1" standalone="yes" ?>
	
	<!-- 
	    To compile it :
	    - go in the bin directory where you installed IzPack
