Usage

This panel allows the user to modify the default installation path.

Example definition

<panel classname="TargetPanel">
   <validator classname="com.izforge.izpack.installer.validator.ConditionValidator"/>
</panel>

The panel will display a panel window with a text area that can be edited by the user and a browse button which allows the user to browse for the desired folder.

The IzPack variable INSTALL_PATH will be set to the user's selection.

TargetPanel checks the $INSTALL_PATH/.installationinformation file on updates when the installer is set to the modification mode, see <writeinstallationinformation> in the <info> section and InstallationTypePanel for more information how to handle this.

Configuration

Use the nested <configuration> (see Panels) element to customize the TargetPanel for your purposes:

Name	Value	Default Value	Description

Name

Value

Default Value

Description

ShowCreateDirectoryMessage

true|false

true

If true, the panel will show the "Target directory will be created" dialog if a directory does not exist.

Since: 5.0 RC5

ShowExistingDirectoryWarning

true|false

true

If true, the panel will show the "The directory already exists! Are you sure you want to install here and possibly overwrite existing files?" warning dialog, if the given directory already exists.

Deactivating this might be convenient in the case of update installers.

Since: 5.0 RC5

Example:

Example of customzing TargetPanel

<panel classname="TargetPanel">
	<validator classname="com.izforge.izpack.installer.validator.ConditionValidator"/>
	<configuration>
		<!-- Don't show warning if target directory already exists -->
		<ShowExistingDirectoryWarning>false</ShowExistingDirectoryWarning>
	</configuration>
</panel>

You can set a the default installation directories for different target installation platforms. When the compiled installer is executed, IzPack chooses the one that matches the assigned platform. This can be achieved by explicitly setting variables with the prefix: TargetPanel.dir. IzPack recognizes this as a built-in variable which can be user-modified.

For a more detailed description see Setting Default Installation Directories.

`PathInputPanel.required`	The chosen directory should exist.
`PathInputPanel.required.forModificationInstallation`	The chosen directory should exist.	The alternative for PathInputPanel.required, if the IzPack variable modify.izpack.install is set "true" and an .installationinformation file exists in the target folder.

`PathInputPanel.notValid`	The chosen directory does not contain the required product.

To change the text "Select the installation path: " to "Select the folder where My Application 2.1 should be installed: ", TargetPanel.info should be specified in a language resource file for each language supported.

install.xml

<resources>
    <res id="TargetPanelText.xml" src="TargetPanelText.xml"/>
    <res id="TargetPanelText.xml_fra" src="TargetPanelText.xml_fra"/>
</resources>

The TargetPanelText.xml file which is the default language resource, should look something like this:

CustomLangPack.xml

<langpack>
	<str id="TargetPanel.info" txt="Select the folder where $APP_NAME $APP_VER should be installed."/>
</langpack>

A similar TargetPanelText.xml.fra file needs to be created to specify the French translation.
