Hello,

I found a behavior that I cannot explain to myself:


//iefmvMain is a TImageEnFolderMView-Object and displays some images.
//Enable MultiSelect and select two or more of these images. After them try this:
procedure Test_BeginSelect;
begin
    //here it's still OK:
    if (iefmvMain.MultiSelectedImagesCount > 0) then begin
    	ShowMessage('Like expected');
    end
    else begin
    	ShowMessage('I''m a little bit confused');
    end;
    //BeginSelectImages makes the difference:
    //- MultiSelectedImagesCount is 0
    //- IsSelected returns False for each image
    //- MultiSelectedImagesList is empty
    iefmvMain.BeginSelectImages;
	if (iefmvMain.MultiSelectedImagesCount > 0) then begin
    	ShowMessage('Like expected');
    end
    else begin
    	ShowMessage('I''m a little bit confused');
    end;
    iefmvMain.EndSelectImages;
end;


Is this an error or is there an important reason for these differences?

Kind Regards

Jens

Hi Jens

BeginSelectImages resets the existing selection. I will add a note to the documentation.
