Sorry, I tried and gives me error with

and also with:

Code: Select all

ON INIT ::oWnd:Center( oApp():oWndMain )

You are using oWnd property of TWindow not of TAlbum. Assign

Code: Select all

oAlbum = Self

at the start of the method and then use

Code: Select all

ON INIT oAlbum:oWnd:Center( oApp():oWndMain )

Thanks Enrico.

I need that TAlbum class inherits from TControl because I need to put it in a dialog. It's very difficult for me to control the application flow with 2 windows, so I need to create a dialog and inside it the talbum class.

I have seen the code from Antonio, and also noticed about the TScrollPanel class existing in FWH. I'll try to build the TAlbum class from TScrollPanel so I'd have scroll features it it.

José Luis

Please wait a little while.
Very soon we are posting full TAlbum class derived from TPanel

Mr. Rao,

I've done what I need just with a TScrollPanel and your code of showing the images. I'll post it when I've a nice sample. I didn't known that FWH has a TScrollPanel control, sorry.

¡¡ Muchas gracias a todos !!

Yes, TScrollPanel works well.

[Antonio Linares]

José Luis,

Very good idea

On the scrollbar, the top and bottom arrows seem not to be working
Same for the mouse wheel

We are going to check it

Mr. Rao,
A new class derived from TScrollPanel would be nice with some added features:
* A new data to tell how many pictures show in a row, and calculate the gutter to adjust and 'center' the row in the control
* Possibility to have one picture highlighted
* Cursor movement in the images, and automatically scroll the images when go down from the latest showed row.

I just give you some ideas for the class

Kind regards,

[JoseAlvarez]

Hola Jose Luis.

Soy jose alvarez , de Venezuela,

podrias ayudarme a hacer este tipo de menu? hace tiempo quiero hacer algo asi y aun no doy con la manera.



Cualquier ayuda sabria agradecerte. Uso Fw 17.01 , xHarbour, Borland 5.5 y Pelles c (solo como editor de recursos)

Un Abrazo,

[José Luis Sánchez]

Hola José,

eso es la clase c5vmenu de Paco García. La tienes completa en los fuentes de Cuaderno de Bitácora que tengo publicados en Github: https://github.com/JoseluisSanchez/bitacora. Ahí están los fuentes y cómo uso yo la clase.

Saludos,

He modificado el código de Mr. Rao para definir el número de imágenes en horizontal que tiene la galería y que calcule el ancho de la imagen en consecuencia. También defino dos separaciones, una vertical y otro horizontal. La vertical la puedo usar para mostrar el título del libro u otro texto. El el código de arriba estoy mostrando el número de registro que corresponde a cada portada, para efectos de depuración, luego quitaré esto. En mi caso además de montar el array de imágenes monto otro de números de registro para que al hace doble click vaya a editar el libro correspondiente. Para conseguir esto he tenido que usar la técnica de 'detached locals' a la hora de crear las imágenes del álbum.

Saludos,
José Luis
