C1.Win.TouchToolKit.C1TouchEventProvider.PointerMoved

PointerMoved Event

Occurs when a pointer moves while the pointer remains within the hit test area of the specific control.

Namespace: C1.Win.TouchToolKit

Assembly: C1.Win.TouchToolKit.8.dll

Syntax

public event EventHandler<PointerEventArgs> PointerMoved

Returns

Type	Description
EventHandler<PointerEventArgs>	Occurs when a pointer moves while the pointer remains within the hit test area of the specific control.

Remarks

In some UI scenarios this event will fire a lot. Be aware of the performance profile for code you put into this handler, and consider ways to use your own flags or tolerances that can throttle how many times the logic actually needs to run.

This event is a routed event. If you do not want parent control receive this event, set PointerEventArgs.Handled

Examples

The following code example shows how to use this event.

This code example is part of a larger example provided for the PointerPressed event.

public class GcTouchEventProviderPointerDemo : Form
{
	private Panel _bluePanel;
	private ListBox _messageListBox;
	private GcTouchEventProvider _gcTouchEventProvider = new GcTouchEventProvider();

	public GcTouchEventProviderPointerDemo()
	{
		InitializeComponent();

		_gcTouchEventProvider.SetEnableTouchEvents(_bluePanel, true);

		_gcTouchEventProvider.PointerMoved += _gcTouchEventProvider_PointerMoved;
	}

	private void _gcTouchEventProvider_PointerMoved(object sender, PointerEventArgs e)
	{
		string log = "Target: " + e.TargetControl.Name + " Event: PointerMoved" + "  X: " + e.Position.X.ToString() + " Y: " + e.Position.Y.ToString();
		_messageListBox.Items.Add(log);
	}

	private void InitializeComponent()
	{
		_bluePanel = new Panel();
		_bluePanel.Name = "Blue";
		_bluePanel.BackColor = Color.Blue;
		_bluePanel.Size = new Size(200, 200);
		_bluePanel.Location = new Point(20, 20);

		_messageListBox = new ListBox();
		_messageListBox.Size = new Size(750, 310);
		_messageListBox.Location = new Point(20, 240);

		this.Controls.Add(_bluePanel);
		this.Controls.Add(_messageListBox);
	}
}
