Is there a way to make vertical scroll bar wider?

[ctrl-alt-d]

My Material Avalonia app uses vertical scroll bars in some controls:

The window scroll bar code:

    <ScrollViewer>
        <StackPanel Orientation="Vertical"
                    Margin="16, 16">
            <Grid>
                <Grid.RowDefinitions>
                    <RowDefinition Height="Auto" />
                    <RowDefinition Height="Auto" />
                    <RowDefinition Height="Auto" />

The list code:

        <ListBox DockPanel.Dock="Bottom"
                 Margin="0"
                 Items="{Binding MyItems, Mode=OneWay}"
                 VirtualizationMode="Simple">
            <ListBox.ItemTemplate>
                <DataTemplate>
                    <pages:AlumneRowUserCtrl/>
                </DataTemplate>
            </ListBox.ItemTemplate>
        </ListBox>

There is some way to make scroll bar control wider? My users say they have problems on windows some time to click on it.

Thanks!

Hello, @ctrl-alt-d

You can set Classes="Classic" for your ScrollViewer and your scrollbar will be look like that:
