Trating class new ( the revenge)

Trating class new ( the revenge)

Postby Silvio.Falconi » Sat Jan 03, 2015 12:49 am

Dear Antonio,

tonight I tried to create the trating class converting the test made from Uwe and I. on old topic (viewtopic.php?f=3&t=29832&start=45)

I can show the images, the caption sample "MyRating" and the test of reset as you can see on this picture

Image



the problem I have on Mousemove method is this :

I load the images and put them on array ::himage[n] and associated the image on a aItem array where I save the number of Image and the coordinates the images

to use ptinrect I must save on an array the coordinates of each bitmap

when I add on aItems the value I have problems

AAdd( ::aItems, {STR(i),.f.,{nRow, nCol,::nbottom-8,20} } )

aItem[1] = number of Image
aItem[2] = select or not select
aItem[3] = coordinates of bitmap x,y,z,k to use with ptinrect function on mousemove method

I used the bitmaps of Uwe test you can found at viewtopic.php?f=3&t=29832&start=45

If the coordinates are the same of Ptinrest it must load onHoverRate method


How I can make to resolve the problem into MouseMove method ?
