[UWP][C++]UWP C++ Aplication not taking or registering any mouse input RRS feed

  • Question

  • I have created a UWP C++  Application and populated it with these controls:

    <StackPanel Orientation="Horizontal">
        <TextBox Name="textToAddTo"/>
        <Button Name="addTextToLabelButton" Content="Add Text" Click="addTextToLabelButton_Click"/>
     <TextBlock Name="ExistText"/>

    With this code behind:

    void CrystalLibUWPC::MainPage::addTextToLabelButton_Click(Platform::Object^ sender, Windows::UI::Xaml::RoutedEventArgs^ e) { ExistText->Text += textToAddTo->Text; }

    My problem is that the application will not take ANY mouse input, but it will take keyboard input, so I can press the tab  key to select and press enter on controls, as this video shows : https://1drv.ms/v/s!AgBD_3oNIAengqNrYkwikgcI2-Be6A

    Any help wold be appreciated,

  • Hello Josh,

    You are putting your textblock and textbox together and then the UI mixed together.

    Please understand the following:

    1. Textbox is a control for input so it can receive inputs from both mouse and keyboard

    2. Textblock can be treated as a label and in this way it will not receive inputs.

    So please modify you UI code like the following:

     <Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
                <RowDefinition Height="400"/>
                <RowDefinition Height="*"/>
            <Border BorderBrush="Black" Grid.Row="0">
                    <TextBox Name="textToAddTo"/>
                    <Button Name="addTextToLabelButton" Content="Add Text" Click="addTextToLabelButton_Click"/>
            <Border BorderBrush="Black" Grid.Row="1">
                    <TextBlock Name="ExistText"/>

    In this way the UI looks different and you will be able to see the difference.
