pierrotsc	Posted - Feb 19 2012 : 15:20:10 I have showhint turn on for my imageenvect. Is it possible to add some code in the onmousemove event to display the RGB values of the pixels under the cursor in real time in a hint window? Right now i am showing the values in a status bar but would like to be shown next to the cursor. Like, when i rotate an image, i can see the rotation degree being displayed. Thanks. P

xequte	Posted - Feb 21 2012 : 02:24:35 Hi You should be able to do this just using the standard hint of TImageEnVect. In the OnMouseMove event set the hint with the RGB value and use CancelHint when it changes. Something like: procedure Tfrmmain.AnIEVectMouseMove(Sender: TObject; Shift: TShiftState; X, Y: Integer); var sHint : string; begin sHint := GetRGBValueAtPos(Sender, X, Y) ; if sHint <> AnIEVect.Hint then begin Application.CancelHint; AnIEVect.Hint := sHint; end; end; Nigel Xequte Software www.xequte.com nigel@xequte.com
pierrotsc	Posted - Feb 20 2012 : 09:15:42 Well, i was just trying to have imageenvect.hint display the current RGB values of the pixel under the cursor. Ok..I'll wait...
fab	Posted - Feb 20 2012 : 00:03:24 Next minor version will have the method SetInteractionHint to allow custom hints in TImageEnView/Vect. It is already present in current version but as "protected", so you need to inherits from TImageEnView/Vect to see it.
