TImageEnMView.SelectedImage

Declaration

property SelectedImage: Integer;

Description

Returns or sets the currently selected image.
The selected image will also become the active image that is returned by IEBitmap and affected by editing operations using Proc.

Note:
◼Setting the selected image when multiple selection is enabled, will deselect all other images. To prevent this use SelectImage or BeginSelectImages
◼Use Deselect to remove selection from an image
◼The selected image is drawn with a colored border
◼The index ignores any active filtering, i.e. SelectedImage := 3; means the fourth image regardless of visibility. See GetUnfilteredImage

Examples

// Show filename of selected image
ShowMessage( ImageEnMView1.ImageFilename[ ImageEnMView1.SelectedImage ]);

// Paint frame number on each thumbnail
ImageEnMView1.LockUpdate();
for i := 0 to ImageEnMView1.ImageCount - 1 do
begin
  ImageEnMView1.SelectedImage := i;
  ImageEnMView1.Proc.TextOut(Align_text_near_top,
                             Align_text_near_left,
                             '#' + IntToStr( i + 1 ),
                             'Arial',
                             32,
                             clRed,
                             [fsBold]);
end;
ImageEnMView1.UnlockUpdate();

// Save only checked images
wasMS := ImageEnMView1.EnableMultiSelect;

  ImageEnMView1.EnableMultiSelect := True;

  ImageEnMView1.BeginSelectImages();
