# IOGesture

![GitHub Release](https://img.shields.io/github/v/release/iolitetech/IOGesture)

A lightweight and easy-to-use library for handling touch and gesture events in Blazor applications. This wrapper is built on top of the [TinyGesture](https://github.com/sciactive/tinygesture) library and provides seamless integration with Blazor components.

## Features

- **Pan Gestures**: Detect and handle pan gestures with start, move, and end callbacks.

- **Swipe Gestures**: Easily recognize swipe gestures in all directions (up, down, left, right).

- **Tap Gestures**: Identify single tap and double tap gestures.

- **Long Press**: Handle long press events.

- **Pinch and Rotate**: Manage pinch (zoom) and rotate gestures, complete with start and end callbacks.

- **Customizable Options**: Configure gesture thresholds and other settings to fine-tune the gesture detection.

:information_source: For more information please check the [TinyGesture](https://github.com/sciactive/tinygesture) repository.

## Getting Started

### Installation

1. Install [IOGesture](https://www.nuget.org/packages/IOGesture) with dotnet cli in your Blazor app.

  ```sh

  dotnet add package IOGesture 

  ```

2. Add the tinygesture.js and IOGesture.js script tag in your root file **_Host.cshtml for Blazor Server Apps** or **index.html for Blazor WebAssembly Apps**:

  ```html

  

  

  

  ```

## Usage

Use the `IOGesture.Components` then you can use the component: 

```Razor

@using IOGesture.Components

  
Swipe me.


```

Then you can listen to gesture event callbacks and pass the options with type of `GestureOptions`, You can access various properties of the gesture using the `Properties` object after you referenced the `Gesture` instance:

```Razor

    

        

    

@code {

    private Gesture? ioGesture;

    private GestureOptions gestureOptions = new GestureOptions

    {

        VelocityThreshold = 10,

        PressThreshold = 8,

        DiagonalSwipes = false,

        DiagonalLimit = 15,

        MouseSupport = true

    };

    private void HandlePanMove()

    {

        Console.WriteLine($"X: {ioGesture.Properties.TouchMoveX}, Y: {ioGesture.Properties.TouchMoveY}");

    }

    private void HandleSwipeLeft()

    {

        // Handle swipe left

    }

}

```

### GestureOptions Configuration

Customize gesture detection by setting properties in GestureOptions:

- **`VelocityThreshold`**: Minimum velocity the gesture must be moving when the gesture ends to be considered a swipe.

- **`PressThreshold`**: Point at which the pointer moved too much to consider it a tap or long press gesture.

- **`DiagonalSwipes`**: If true, swiping in a diagonal direction will fire both a horizontal and a vertical swipe.

- **`DiagonalLimit`**: The degree limit to consider a diagonal swipe when DiagonalSwipes is true.

- **`MouseSupport`**: Listen to mouse events in addition to touch events (for desktop support).
