Modify Extract Installer Example
Modify Extract Installer illustrates how to overwrite the component.createOperationsForArchive()
function to be able to install a component to a modified path.
<?xml version="1.0" encoding="UTF-8"?> <Installer> <Name>Modify Extract Installer Example</Name> <Version>1.0.0</Version> <Title>Modify Extract Installer Example</Title> <Publisher>Qt-Project</Publisher> <StartMenuDir>Qt IFW Examples</StartMenuDir> <TargetDir>@HomeDir@/IfwExamples/modifyextract</TargetDir> </Installer>
- The
<Default>
element is set totrue
to preselect the component in the installer. - The
<Script>
element specifies the file name of the JavaScript file that is loaded to perform operations.
<?xml version="1.0"?> <Package> <DisplayName>Modify extract operation</DisplayName> <Description>A component that uses a hook to modify the extract operation.</Description> <Version>1.0.1</Version> <ReleaseDate>2014-12-19</ReleaseDate> <Default>true</Default> <Script>installscript.js</Script> </Package>
Modifying Target Path
In installscript.js, we overwrite the default component.createOperationsForArchive()
implementation to be able to register an Extract
operation with a custom argument:
Component.prototype.createOperationsForArchive = function(archive) { component.addOperation("Extract", archive, "@TargetDir@/extractToAnotherPath"); }
