GUI Development (WPF)

Purpose: The GUI development for the Find Visual Studio Orphaned Items application leverages the WPF framework. The core components of the application’s UI are built using XAML files for layout and structure, and C# code-behind files for logic and interaction.

File Structure:

• MainWindow.xaml: This file defines the main window of the application.
• MainWindow.xaml.cs: This file contains the C# code-behind for the main window, handling events and logic.
• FindOrphanedItemsViewModel.cs: This view model provides data and functionality for the main window.
• Other Supporting XAML Files: The application uses other XAML files to define components like dialog boxes or custom user controls (not shown in the example below).

Example Code:

<Window x:Class="FindOrphanedItems.MainWindow"
                  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                  xmlns:local="clr-namespace:FindOrphanedItems"
                  Title="Find Visual Studio Orphaned Items" 
                  Height="450" Width="800">
              <Grid>
                  <Grid.RowDefinitions>
                      <RowDefinition Height="Auto" />
                      <RowDefinition Height="*" />
                      <RowDefinition Height="Auto" />
                  </Grid.RowDefinitions>
                  <Grid.ColumnDefinitions>
                      <ColumnDefinition Width="*" />
                      <ColumnDefinition Width="Auto" />
                  </Grid.ColumnDefinitions>
          
                  <Label Grid.Row="0" Grid.Column="0" Grid.ColumnSpan="2" 
                         Content="Find Visual Studio Orphaned Items" 
                         FontSize="18" FontWeight="Bold" 
                         HorizontalAlignment="Center" Margin="10"/>
          
                  <ScrollViewer Grid.Row="1" Grid.Column="0" Margin="10">
                      <ListBox ItemsSource="{Binding OrphanedItems}" 
                              x:Name="OrphanedItemsListBox" 
                              SelectionMode="Multiple">
                          <ListBox.ItemTemplate>
                              <DataTemplate>
                                  <TextBlock Text="{Binding Name}" />
                              </DataTemplate>
                          </ListBox.ItemTemplate>
                      </ListBox>
                  </ScrollViewer>
          
                  <Button Grid.Row="2" Grid.Column="0" Content="Scan" 
                          Margin="10" Command="{Binding ScanCommand}"/>
          
                  <Button Grid.Row="2" Grid.Column="1" Content="Delete Selected"
                          Margin="10" Command="{Binding DeleteSelectedCommand}"/>
              </Grid>
          </Window>
          

Explanation:

• XAML: Defines the visual structure of the main window using Grid elements for layout, controls like Label, Button, ListBox, ScrollViewer and data binding to the view model.
• Code-Behind: The corresponding MainWindow.xaml.cs file handles events for buttons and interacts with the view model (FindOrphanedItemsViewModel) to update UI elements based on user actions.
• Data Binding: The ListBox uses data binding (ItemsSource="{Binding OrphanedItems}") to display a list of orphaned items retrieved from the view model.
• Commands: The ScanCommand and DeleteSelectedCommand are bound to buttons to trigger specific actions in the view model.

Notes:

• The application utilizes the MVVM (Model-View-ViewModel) pattern to separate concerns and promote maintainability.
• The FindOrphanedItemsViewModel class handles the logic for scanning for orphaned items, deleting them, and updating the UI.

Important: This outline is intended as a brief overview of the GUI development approach for this application. It may not cover all aspects of the application’s UI, but provides a foundation for understanding the core concepts and structure.
