Qt Installer with background picture

Question

I'm elaborating the installer for my application using Qt Installer Framework.

I would like to show a picture on the background so I set Background tag as indicated on https://doc.qt.io/qtinstallerframework/ifw-globalconfig.html and set WizardStyle to Mac and it looks like the following:

Here is config.xml

<?xml version="1.0" encoding="UTF-8"?>
<Installer>
    <Name>Stylesheet Example</Name>
    <Version>1.0.0</Version>
    <Title>Stylesheet Example</Title>
    <Publisher>Qt-Project</Publisher>
    <StartMenuDir>Qt IFW Examples</StartMenuDir>
    <TargetDir>@HomeDir@/IfwExamples/stylesheet</TargetDir>
    <WizardStyle>Mac</WizardStyle>
    <StyleSheet>style.qss</StyleSheet>
    <!-- <TitleColor>#FFFFFF</TitleColor> -->
    <WizardShowPageList>false</WizardShowPageList>
    <Background>background1.png</Background>
</Installer>

How can I make that semi-transparent (white) part fully transparent?

Answer 1

In your style.qss file add these lines below:

QFrame, QLabel, QToolTip {
    border: 0px;
    background-color: transparent;
}
