Usage

This panel allows the user to modify the default installation path on the target computer.

Example definition

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

Once chosen, the IzPack variable INSTALL_PATH is set to the user's choice.

Configuration

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

Name Value Default Value Description

ShowCreateDirectoryMessage

true|false

true

Whether to show the "Target directory will be created" dialog if a directory does not exist.

Since: 5.0 RC5

ShowExistingDirectoryWarning

true|false

true

Whether to 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 for providing 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>

IzPack offers the possibility to set a list of default installation directories depending on the target installation platform. When the compiled installer is executed, IzPack chooses the one matching 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.

Built-in Variable Description Default Value

TargetPanel.dir.<platform_or_os>

(see Setting Default Installation Directories)

The platform-specific default installation path, which can be overridden by the user in TargetPanel.

(gathered automatically according to the OS and platform)

~~ShowCreateDirectoryMessage~~ ~~Whether to show the "Target directory will be created" dialog if a directory does not exist.~~
You should not use this variable any longer, use the <configuration> option with the same name see above. ~~true~~

`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.
