Creating a full-featured WPF application for recipe management and filtering can be quite extensive, but I'll provide a comprehensive starting point. This project will involve creating several classes, XAML for the UI, and some C# code-behind for logic.
Here's a simplified version of such an application:
### Step 1: Create the Recipe and Ingredient Models
First, create a new WPF project and add classes for `Recipe` and `Ingredient`.
**Ingredient.cs**
```csharp
public class Ingredient
{
public string Name { get; set; }
public double Quantity { get; set; }
public string Measurement { get; set; }
public double Calories { get; set; }
public string FoodGroup { get; set; }
}
```
**Recipe.cs**
```csharp
using System.Collections.Generic;
public class Recipe
{
public string Name { get; set; }
public List<Ingredient> Ingredients { get; set; }
public List<string> Steps { get; set; }
}
```
### Step 2: Create the Main Window XAML
**MainWindow.xaml**
```xml
<Window x:Class="RecipeManager.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Recipe Manager" Height="600" Width="800">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="3*" />
<ColumnDefinition Width="2*" />
</Grid.ColumnDefinitions>
<StackPanel Grid.Column="0">
<TextBlock Text="Add New Recipe" Margin="10" FontWeight="Bold" />
<TextBox x:Name="RecipeName" PlaceholderText="Recipe Name" Margin="10"/>
<TextBlock Text="Ingredients" Margin="10" FontWeight="Bold" />
<StackPanel x:Name="IngredientPanel" />
<Button Content="Add Ingredient" Click="AddIngredient_Click" Margin="10" />
<TextBlock Text="Steps" Margin="10" FontWeight="Bold" />
<StackPanel x:Name="StepsPanel" />
<Button Content="Add Step" Click="AddStep_Click" Margin="10" />
<Button Content="Save Recipe" Click="SaveRecipe_Click" Margin="10" />
</StackPanel>
<StackPanel Grid.Column="1">
<TextBlock Text="Stored Recipes" Margin="10" FontWeight="Bold" />
<ListBox x:Name="RecipeList" SelectionChanged="RecipeList_SelectionChanged" Margin="10"/>
<Button Content="Scale x0.5" Click="ScaleHalf_Click" Margin="10" />
<Button Content="Scale x2" Click="ScaleDouble_Click" Margin="10" />
<Button Content="Scale x3" Click="ScaleTriple_Click" Margin="10" />
<Button Content="Reset Scale" Click="ResetScale_Click" Margin="10" />
<TextBlock x:Name="TotalCalories" Margin="10" />
</StackPanel>
</Grid>
</Window>
```
### Step 3: Code-Behind Logic
**MainWindow.xaml.cs**
```csharp
using System;
using System.Collections.Generic;
using System.Linq;
using System.Windows;
using System.Windows.Controls;
namespace RecipeManager
{
public partial class MainWindow : Window
{
private List<Recipe> recipes = new List<Recipe>();
private List<Ingredient> currentIngredients = new List<Ingredient>();
private List<string> currentSteps = new List<string>();
private Recipe selectedRecipe;
private double scaleFactor = 1;
public MainWindow()
{
InitializeComponent();
}
private void AddIngredient_Click(object sender, RoutedEventArgs e)
{
var ingredientDialog = new IngredientDialog();
if (ingredientDialog.ShowDialog() == true)
{
var ingredient = ingredientDialog.Ingredient;
currentIngredients.Add(ingredient);
IngredientPanel.Children.Add(new TextBlock { Text = $"{ingredient.Quantity} {ingredient.Measurement} of {ingredient.Name} ({ingredient.Calories} calories, {ingredient.FoodGroup})" });
}
}
private void AddStep_Click(object sender, RoutedEventArgs e)
{
var stepDialog = new InputDialog("Enter Step Description:");
if (stepDialog.ShowDialog() == true)
{
var step = stepDialog.InputText;
currentSteps.Add(step);
StepsPanel.Children.Add(new TextBlock { Text = step });
}
}
private void SaveRecipe_Click(object sender, RoutedEventArgs e)
{
var recipe = new Recipe
{
Name = RecipeName.Text,
Ingredients = new List<Ingredient>(currentIngredients),
Steps = new List<string>(currentSteps)
};
recipes.Add(recipe);
RecipeList.Items.Add(recipe.Name);
ClearRecipeInputs();
}
private void RecipeList_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
if (RecipeList.SelectedItem == null) return;
var selectedRecipeName = RecipeList.SelectedItem.ToString();
selectedRecipe = recipes.FirstOrDefault(r => r.Name == selectedRecipeName);
DisplayRecipe(selectedRecipe);
}
private void DisplayRecipe(Recipe recipe)
{
IngredientPanel.Children.Clear();
foreach (var ingredient in recipe.Ingredients)
{
IngredientPanel.Children.Add(new TextBlock { Text = $"{ingredient.Quantity * scaleFactor} {ingredient.Measurement} of {ingredient.Name} ({ingredient.Calories * scaleFactor} calories, {ingredient.FoodGroup})" });
}
StepsPanel.Children.Clear();
foreach (var step in recipe.Steps)
{
StepsPanel.Children.Add(new TextBlock { Text = step });
}
double totalCalories = recipe.Ingredients.Sum(i => i.Calories * scaleFactor);
TotalCalories.Text = $"Total Calories: {totalCalories}";
if (totalCalories > 300)
{
TotalCalories.Foreground = Brushes.Red;
MessageBox.Show("Warning: Total calories exceed 300!", "Warning", MessageBoxButton.OK, MessageBoxImage.Warning);
}
else
{
TotalCalories.Foreground = Brushes.Black;
}
}
private void Scale(double factor)
{
scaleFactor = factor;
if (selectedRecipe != null)
{
DisplayRecipe(selectedRecipe);
}
}
private void ScaleHalf_Click(object sender, RoutedEventArgs e)
{
Scale(0.5);
}
private void ScaleDouble_Click(object sender, RoutedEventArgs e)
{
Scale(2);
}
private void ScaleTriple_Click(object sender, RoutedEventArgs e)
{
Scale(3);
}
private void ResetScale_Click(object sender, RoutedEventArgs e)
{
Scale(1);
}
private void ClearRecipeInputs()
{
RecipeName.Clear();
IngredientPanel.Children.Clear();
StepsPanel.Children.Clear();
currentIngredients.Clear();
currentSteps.Clear();
}
}
}
```
### Step 4: Create Dialogs for Adding Ingredients and Steps
**IngredientDialog.xaml**
```xml
<Window x:Class="RecipeManager.IngredientDialog"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Add Ingredient" Height="300" Width="400">
<StackPanel Margin="10">
<TextBox x:Name="Name" PlaceholderText="Ingredient Name" />
<TextBox x:Name="Quantity" PlaceholderText="Quantity" />
<TextBox x:Name="Measurement" PlaceholderText="Measurement" />
<TextBox x:Name="Calories" PlaceholderText="Calories" />
<TextBox x:Name="FoodGroup" PlaceholderText="Food Group" />
<Button Content="Add" Click="Add_Click" />
</StackPanel>
</Window>
```
**IngredientDialog.xaml.cs**
```csharp
using System.Windows;
namespace RecipeManager
{
public partial class IngredientDialog : Window
{
public Ingredient Ingredient { get; private set; }
public IngredientDialog()
{
InitializeComponent();
}
private void Add_Click(object sender, RoutedEventArgs e)
{
Ingredient = new Ingredient
{
Name = Name.Text,
Quantity = double.Parse(Quantity.Text),
Measurement = Measurement.Text,
Calories = double.Parse(Calories.Text),
FoodGroup = FoodGroup.Text
};
DialogResult = true;
Close();
}
}
}
```
**InputDialog.xaml**
```xml
<Window x:Class="RecipeManager.InputDialog"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Input" Height="200" Width="300">
<StackPanel Margin="10">
<TextBox x:Name="InputTextBox" />
<Button Content="OK" Click="Ok_Click" />
</StackPanel>
</Window>
```
**InputDialog.xaml.cs**
```csharp
using System.Windows;
namespace RecipeManager
{
public partial class InputDialog : Window
{
public string InputText { get; private set; }
public InputDialog(string prompt)
{
InitializeComponent();
InputTextBox.PlaceholderText = prompt;
}
private void Ok_Click(object sender, RoutedEventArgs e)
{
InputText = InputTextBox.Text;
DialogResult = true;
Close();
}
}
}
```
### Step 5: Add Filtering Mechanism
This step involves adding more UI elements for filtering and implementing related logic.
**MainWindow.xaml** (add to the existing code)
```xml
<TextBlock Text="Filter Recipes" Margin="10" FontWeight="Bold" />
<TextBox x:Name="IngredientFilter" PlaceholderText="Ingredient Filter" Margin="10"/>
<TextBox x:Name="FoodGroupFilter" PlaceholderText="Food Group Filter" Margin="10"/>
<TextBox x:Name="MaxCaloriesFilter" PlaceholderText="Max Calories" Margin="10"/>
<Button Content="Apply Filters" Click="ApplyFilters_Click" Margin="10" />
<Button Content="Clear Filters" Click="ClearFilters_Click" Margin="10" />
```
**MainWindow.xaml.cs** (add to the existing code)
```csharp
private void ApplyFilters_Click(object sender, RoutedEventArgs e)
{
var ingredientFilter = IngredientFilter.Text.ToLower();
var foodGroupFilter = FoodGroupFilter.Text.ToLower();
if (!double.TryParse(MaxCaloriesFilter.Text, out var maxCaloriesFilter))
{
maxCaloriesFilter = double.MaxValue;
}
var filteredRecipes = recipes.Where(r =>
(string.IsNullOrEmpty(ingredientFilter) || r.Ingredients.Any(i => i.Name.ToLower().Contains(ingredientFilter))) &&
(string.IsNullOrEmpty(foodGroupFilter) || r.Ingredients.Any(i => i.FoodGroup.ToLower().Contains(foodGroupFilter))) &&
r.Ingredients.Sum(i => i.Calories) <= maxCaloriesFilter);
RecipeList.Items.Clear();
foreach (var recipe in filteredRecipes)
{
RecipeList.Items.Add(recipe.Name);
}
}
private void ClearFilters_Click(object sender, RoutedEventArgs e)
{
IngredientFilter.Clear();
FoodGroupFilter.Clear();
MaxCaloriesFilter.Clear();
RecipeList.Items.Clear();
foreach (var recipe in recipes)
{
RecipeList.Items.Add(recipe.Name);
}
}
```
With these steps, you have constructed a WPF application that meets the specified requirements for managing, displaying, scaling, and filtering recipes. Feel free to expand on this code base to further enhance the application as needed.
create a graphical user interface using a WPF to allow a user to 1. enter an unlimited amount of recipes and store it. the user must enter a recipe name, how many ingredients they want, the quantity and meassurement of each ingredient,the calorie of each ingredient and the food group of the ingredients and then the user should be able to enter how many steps the recipe has and a description of those steps. 2. the user must be able to choose from the recipes that were stored to be displayed and for each recipe the calories of each ingredient should be added up and displayed as the total calories, if the total calories exceed 300 the a warning message must be displayed in red. 3. the user should be able to scale the quantities of the ingredients in each recipe by a factor of 0.5 , 2 or 3 and the new qauntities should be displayed. 4. the user should be able to scale the recipe back to its original quantities and the be able to be displayed. Lastly 5. The user shall be able to filter the list of recipes by:
a. entering the name of an ingredient that must be in the recipe,
b. choosing a food group that must be in the recipe, or
c. selecting a maximum number of calories. Show all the final code
