FloaterPosition Property

Summary

Gets or sets the position of the floater.

Syntax

C++/CLI

C++

public virtual Point FloaterPosition { get; set; }

public: 
virtual property Point FloaterPosition { 
   Point get(); 
   void set (    Point ); 
}

public:  
   virtual property Point^ FloaterPosition 
   { 
      Point^ get() 
      void set(Point^ value) 
   }

Property Value

A System.Drawing.Point object that represents the top-left position used when painting the FloaterImage.

Remarks

You can manually set the value of this property to control where the FloaterImage is painted.

When the InteractiveMode of this RasterImageVieweris set to RasterViewerInteractiveMode.Floater, the viewer will update the value of this property as the user drags the FloaterImage around.

Example

This sample creates a floater and lets the user move it.

using Leadtools.WinForms; 
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Color; 
using Leadtools.Drawing; 
 
private void viewer_InteractiveFloater(object sender, RasterViewerPointEventArgs e) 
{ 
   // show information about the user interaction 
   RasterImageViewer viewer = sender as RasterImageViewer; 
   Console.WriteLine("Status: {0}, Canceled: {1}, Point: {2}, Floater Position: {3}", e.Status, e.Cancel, e.Point, viewer.FloaterPosition); 
} 
 
public void RasterImageViewer_FloaterPosition(RasterImageViewer viewer) 
{ 
   // hook into the viewer InteractiveFloater event to get updated whenever the user moves the floater. 
   viewer.InteractiveFloater += new EventHandler<RasterViewerPointEventArgs>(viewer_InteractiveFloater); 
 
   // add a floater the viewer and start the floater interactive mode 
   // we are going to create the floater image manually as a red ellipse with a region. 
 
   RasterColor[] palette = new RasterColor[0]; 
   RasterImage floaterImage = new RasterImage( 
      RasterMemoryFlags.Conventional, 
      200, 
      200, 
      24, 
      RasterByteOrder.Bgr, 
      RasterViewPerspective.TopLeft, 
      palette, 
      IntPtr.Zero, 
      0 
      ); 
 
   using (RasterImageGdiPlusGraphicsContainer container = new RasterImageGdiPlusGraphicsContainer(floaterImage)) 
   { 
      container.Graphics.FillRectangle(Brushes.Black, 0, 0, floaterImage.ImageWidth, floaterImage.ImageHeight); 
      container.Graphics.FillEllipse(Brushes.Red, 0, 0, floaterImage.ImageWidth, floaterImage.ImageHeight); 
   } 
 
   floaterImage.AddColorToRegion(RasterColor.FromKnownColor(RasterKnownColor.Red), RasterRegionCombineMode.Set); 
 
   viewer.FloaterImage = floaterImage; 
   viewer.FloaterVisible = true; 
   viewer.FloaterPosition = new Point(100, 100); 
   viewer.InteractiveMode = RasterViewerInteractiveMode.Floater; 
 
   MessageBox.Show("Click and move the floater"); 
}
