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

Since: 5.0 RC5


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.

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

 For a more detailed description see Setting Default Installation Directories.

Built-in VariableDescriptionDefault Value


(see Setting Default Installation Directories)

(gathered determined automatically according to the OS and platform)

ShowCreateDirectoryMessageWhether 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.

See the  InstallationTypePanel for more installation how the modify.izpack.install variable is automatically set.
PathInputPanel.notValidThe 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.


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

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

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

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