Hide Checkbox Example

Hide Checkbox illustrates how to hide the checkbox for an item.

Configuring the Example Installer

The installer configuration file, config.xml, in the config directory specifies the text and default values used in the installer:

• The <Name> element sets the application name and adds it to the page name and introduction text.
• The <Version> element sets the application version number.
• The <Title> element sets the installer name and displays it on the title bar.
• The <Publisher> element sets the publisher of the software (as shown in the Windows Control Panel, for example).
• The <StartMenuDir> element sets the name of the default program group for the product in the Windows Start menu.
• The <TargetDir> element sets the default target directory location to be within the IfwExamples directory in the home directory of the current user (because it uses the pre-existing variable , @HomeDir@, as part of the value). For more information, see Predefined Variables.

<?xml version="1.0" encoding="UTF-8"?>
<Installer>
    <Name>Hide item checkbox</Name>
    <Version>1.0.0</Version>
    <Title>Hide checkbox</Title>
    <Publisher>The Qt Company</Publisher>
    <StartMenuDir>Qt IFW Examples</StartMenuDir>
    <TargetDir>@HomeDir@/IfwExamples/hidecheckbox</TargetDir>
</Installer>

Creating the Example Package Information File

The installer package information file, package.xml, in the meta directory specifies the components that are available for installation:

• The <DisplayName> element sets the human-readable name of the component.
• The <Description> element sets the human-readable description of the component.
• The <Version> element sets the version number of the component.
• The <ReleaseDate> element sets the date of release for this component version.

• The <Checkable> element specifies whether a checkbox is displayed next to an item. Set to false to hide the checkbox for the item.

This example attempts to install three components, so we create a package.xml file in each component directory: componentF, componentF.subcomponent1, and componentF.subcomponent1.subcomponent1. We also specify the component name and description in each of them. The top level item, componentF, has <Checkable> set to false, so it cannot be selected.

<?xml version="1.0"?>
<Package>
    <DisplayName>Uncheckable component</DisplayName>
    <Description>This component is uncheckable.</Description>
    <Version>1.0.0</Version>
    <ReleaseDate>2015-12-01</ReleaseDate>
    <SortingPriority>40</SortingPriority>
    <Checkable>false</Checkable>
</Package>

Generating the Example Installer

To create the example installer, switch to the example source directory on the command line and enter the following command:

• On Windows:

  ..\..\bin\binarycreator.exe -c config\config.xml -p packages installer.exe

• On Linux or macOS:

  ../../bin/binarycreator -c config/config.xml -p packages installer

This creates the installer to the current directory.
