[izpack-users] How to use validations in TargetPanel?

[Miraodb]

Hi,

You can't do that using the normal targetpanel.
You would have to use a custom panel to do the trick.
Here is the one i use:

/*
 * Created on 29.06.2005
 *
 * TODO To change the template for this generated file go to
 * Window - Preferences - Java - Code Style - Code Templates
 */
package com.izforge.izpack.panels;

import com.izforge.izpack.installer.InstallData;
import com.izforge.izpack.installer.InstallerFrame;


/**
 * @author fabrice mirabile
 */
public class NonBlankTargetPanel extends TargetPanel
{
    private static final long serialVersionUID = 3248705610571943817L;

    public NonBlankTargetPanel(InstallerFrame parent, InstallData idata)
    {
        super(parent, idata);
    }

    public boolean isValidated()
    {
      String chosenPath = pathSelectionPanel.getPath();
      if(chosenPath == null || chosenPath.length() < 1 )
        return( false );
      if( chosenPath.indexOf(" ") >= 0 )
      {
        emitError(parent.langpack.getString("installer.error"),
          parent.langpack.getString("NonBlankTargetPanel.noBlanks"));
        return( false );
      }
      return(super.isValidated() );
    }

    public void panelActivate()
    {
      super.panelActivate();
      String chosenPath = pathSelectionPanel.getPath();
      if(chosenPath == null || chosenPath.length() < 1 )
        return;
      if( chosenPath.indexOf(" ") >= 0 )
          pathSelectionPanel.setPath("");
    }


}


To use it:

Create NonBlankTargetPanel.java file with this code in it.
Add it to the izpack-src\src\lib\com\izforge\izpack\panels folder.

Add the following tagert rule into the ant build.xml:

<build-panel name="NonBlankTargetPanel">
           <include name="com/izforge/izpack/panels/PathInputPanel.java"/>
           <include
name="com/izforge/izpack/panels/PathSelectionPanel.java"/>
           <include name="com/izforge/izpack/panels/TargetPanel.java"/>
           <include
name="com/izforge/izpack/panels/TargetPanelAutomationHelper.java"/>
           <include
name="com/izforge/izpack/panels/NonBlankTargetPanel.java"/>
</build-panel>

Then run ant clean, ant all.

Now you can use this new panel as follows in install.xml:

<panel classname="NonBlankTargetPanel"/>

instead of <panel classname="TargetPanel"/>

Hope that helps,
Fabrice
