New Rating Class

[Antonio Linares]

Silvio,

ok, the stars are getting painted not from the top, but from the next to the right.

These are the points that PolyForms() is returning:


So you have to use:
{ aPoints[ 9 ], aPoints[ 10 ], aPoints[ 1 ], aPoints[ 2 ], aPoints[ 3 ], aPoints[ 4 ], aPoints[ 9 ] }

[Silvio.Falconi]

ok but I not Know how do it .. I am off of head

[Antonio Linares]

Silvio,

Code: Select all  Expand view

DO CASE
       CASE ::nType=1

    //Create stars
    //---------------------------------------------------------------------------------
     aPoints = PolyForms( rc[1]-2, rc[2]-8,::nStarWidth,::nStarHeight,5,-18,31 )
     aPoints = { aPoints[ 9 ], aPoints[ 10 ], aPoints[ 1 ], aPoints[ 2 ], aPoints[ 3 ], aPoints[ 4 ], aPoints[ 9 ] }
     PolyPolygon( ::hDc, aPoints )

[Silvio.Falconi]

Antonio,
I allready tried it
and I tried also
aPoints = { aPoints[ 9 ], aPoints[ 8 ], aPoints[ 7 ], aPoints[ 6 ], aPoints[ 5], aPoints[ 4 ], aPoints[ 9 ] }


for the ntype can be 1 , 2 or 3
I changed the ntype value on LButtonUp method but I not had success

[Silvio.Falconi]

antonio, I not found the solution

/*PolyForms( <nRow>, <nCol>, <nWidth>, <nHeight>, <nLados>, <nGiro>, <nPorCent> )

   Función que crea un ARRAY con las coordenadas de los vertices de un polígono
regular para dibujarlo con PolyPolygon(). El polígono puede ser normal
o en estrella.

<nRow>, <nCol>      Coordenadas de la esquina superior izquierda de la zona
                    cuadrángular en la que se va a inscribir el polígono.

<nWidth>, <nHeight> Dimesiones de la zona cuadrángular. Puede definirse como
                    un cuadrado o como un rectángulo, en cuyo caso el
                    polígono se deforma para adaptarse a la superficie.

<nLados>            Número de lados del polígono regular.

<nGiro>             Cantidad de grados que deseamos girar el polígono con
                    respecto a la horizontal (en sentido horario).
                    Por defecto '0'.

<nPorCent>          Para dibujarlos en forma de estrella. Si vale 100 el
                    polígono se dibuja normal. Por defecto vale 100. Con otro
                    valor se dibuja en forma de estrella. Este valor indica
                    el porcentaje del radio interior con respecto al radio
                    exterior. Cuanto menor sea ese valor, mayor será el efecto
                    estrella, las puntas saldrán más estrechas y profundas.

Silvio,

What drawing do you get with this code ?

aPoints = PolyForms( rc[1]-2, rc[2]-8,::nStarWidth,::nStarHeight,5,-18,31 )
aPoints = { aPoints[ 9 ], aPoints[ 10 ], aPoints[ 1 ], aPoints[ 2 ], aPoints[ 3 ], aPoints[ 4 ], aPoints[ 9 ] }
PolyPolygon( ::hDc, aPoints )

[Silvio.Falconi]

If I understood your suggestion

The part at right of the star ( ntype 1)
aPoints := { aPoints[ 9 ], aPoints[ 10 ], aPoints[ 1 ], aPoints[ 2 ], aPoints[ 3 ], aPoints[ 4 ], aPoints[ 9 ] }

the part at left of the star ( ntype 2)
aPoints := { aPoints[ 9 ], aPoints[ 8 ], aPoints[ 7 ], aPoints[ 6 ], aPoints[ 5], aPoints[ 4 ], aPoints[ 9 ] }

the full star ( ntype 3) ( default)
aPoints := PolyForms( rc[1]-2, rc[2]-8,::nStarWidth,::nStarHeight,5,-18,31 )

[Antonio Linares]

Try it

[Silvio.Falconi]

Antonio,

if I insert ntype 1 or nType 2 erase the picture and draw only the part Left or Right

Perhaps it can run ok if the procedure not erase the picture but refill only the part left ( ntype 1) and right ( ntype 2)

/*PolyForms( <nRow>, <nCol>, <nWidth>, <nHeight>, <nLados>, <nGiro>, <nPorCent> )

   Función que crea un ARRAY con las coordenadas de los vertices de un polígono
regular para dibujarlo con PolyPolygon(). El polígono puede ser normal
o en estrella.

<nRow>, <nCol>      Coordenadas de la esquina superior izquierda de la zona
                    cuadrángular en la que se va a inscribir el polígono.

<nWidth>, <nHeight> Dimesiones de la zona cuadrángular. Puede definirse como
                    un cuadrado o como un rectángulo, en cuyo caso el
                    polígono se deforma para adaptarse a la superficie.

<nLados>            Número de lados del polígono regular.

<nGiro>             Cantidad de grados que deseamos girar el polígono con
                    respecto a la horizontal (en sentido horario).
                    Por defecto '0'.

<nPorCent>          Para dibujarlos en forma de estrella. Si vale 100 el
                    polígono se dibuja normal. Por defecto vale 100. Con otro
                    valor se dibuja en forma de estrella. Este valor indica
                    el porcentaje del radio interior con respecto al radio
                    exterior. Cuanto menor sea ese valor, mayor será el efecto
                    estrella, las puntas saldrán más estrechas y profundas.

[Antonio Linares]

Silvio,

Half star is just another painting mode of a star. So it is just another case of your do case in Method Paint().

[Silvio.Falconi]

yes but if I draw half star for sample left it erase the right of all stars and for that star

[Antonio Linares]

Silvio,

You paint the star with white background (o the color you want), then you paint half star on top of it with another color

[ukoenig]

I'm working on a different solution using 2 images :
It would be possible as well using a image, showing a quarter of an star.
Only 1 empty star-image is used.
The 2. star-image could have a different style.

Maybe still better, counting empty and full stars next to each other.
1 full empty star
1 half empty star
1 full colored star
1 half colored star



how it works :

3 images used :

1. I display the empty star-image with the calculated width ( 50 % )
2. I display the startpos. of the 2. star-image 75 % ( with the half star ) using the empty star-endpos.
3. I calculate the needed image-width of the used 2. image ( half star + 2 full stars. )



best regards
Uwe

[Silvio.Falconi]

Uew,
do you converte it on a class ( control ) ?

[ukoenig]

Silvio,

only the calculation for the moment.
Maybe You can include the logic inside Your class.

best regards
Uwe
