Gu.Wpf.ToolTips

Project for tooltips that works for touch users.

Simple sample:

<AdornerDecorator>
    <!-- more content here -->
    <TextBlock HorizontalAlignment="Left"
               Text="Some text with toolip">
        <toolTips:TouchToolTipService.ToolTip>
            <ToolTip>
                <TextBlock Text="Tooltip text" />
            </ToolTip>
        </toolTips:TouchToolTipService.ToolTip>
    </TextBlock>
</AdornerDecorator>

Sample toggle visibility:

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto" />
        <RowDefinition Height="20" />
        <RowDefinition Height="Auto" />
    </Grid.RowDefinitions>
    <CheckBox x:Name="IsOverlayVisible"
              Content="IsOverlayVisible"
              IsChecked="True" />

    <TextBlock Grid.Row="2"
               HorizontalAlignment="Left"
               Text="Some text with toolip"
               toolTips:TouchToolTipService.IsOverlayVisible="{Binding IsChecked,
                                                                       ElementName=IsOverlayVisible}">
        <toolTips:TouchToolTipService.ToolTip>
            <ToolTip>
                <TextBlock Text="Tooltip text" />
            </ToolTip>
        </toolTips:TouchToolTipService.ToolTip>
    </TextBlock>
</Grid>

How it works:

By setting toolTips:TouchToolTipService.ToolTip the controls tooltip is set and a transparent overlay with a button controlling tooltip visibility is added to the control. For custom styling use a different style for PopupButton the default shows a blue circle with a white i hinting a touch user that there is a tooltip that can be toggled by tapping.
