Check columns ( how-to )

B4X:

cc(2).Initialize2 ...
cc(2).RowIconTop  = 6dip 
cc(2).RowIconLeft = 6dip 
cc(2).setTypeCheck

the column will display a green tick if the value of the column is "1"
nothing otherwise

RowIconTop and RowIconLeft can be used to adjust
the position of the tick in the cell

@aviario

to setup a custom image for check columns
you can use an image column with a single value
cc(0).Initialize ...
cc(0).RowIconPut("1",bmp)
cc(0).SetTypeImage
anyway i'm adding the property for the image
and also the value

what do you mean for printing?

If you know of any library to print on printer

In the grid when the text of the column is larger than the width puts in two columns, there is the possibility to resize the height of that column automatically?

stefanobusetto · May 28, 2013

No. I've developed an application that needs to print and i've decided to create pdfs. I've a good lib for that.

There is no autosize planned sorry.

Hi,
If i use Cgrid.ScrollTop, grid goes to first line, but can i select by code the first line?

Thanks

stefanobusetto · May 30, 2013

Hi,
you can use SelectRow. I've exposed the method and posted version 2.05.
I've also added
- CheckIcon to set the icon
- CheckValue to set the "check" value
for the check columns

Hello,

Can i set a diferent Row Height in grid?.

Thanks

stefanobusetto · Jun 12, 2013

The RowHeight property allows to the the height of the rows.
I think you want to set instead the height of a given row.
Isn't it?

aviario · Jun 12, 2013

Yes. Thanks

Whether it is possible to make FastScroll for big grids?
Like ListView1.FastScrollEnabled

stefanobusetto · Jun 14, 2013

@jrat
great idea!
i'll add in the next release

B4X:

Grid.Initialize("Grid")

Dim c(4) As xnGridCol
c(0).Initialize ( "Cod." , "cod" , 15%x )
c(1).Initialize ( "Des." , "des" , 60%x )
...

For i = 0 To c.Length - 1
    Grid.AppendCol ( c(i) )
Next

...

Dim ss As String
ss = "select cod , des , ... from ... " 

Grid.DeleteRows

Dim cc As Cursor
cc = Main.db.execquery ( ss & " limit 100 ")
Grid.CursorAppend ( cc )

stefanobusetto · Jun 17, 2013

Please try
...GridWidth=1
instead of
...GridWidth=1dip

stefanobusetto · Jun 17, 2013

i use the grid with several devices
smartphones an tablets and
i've no problems with the grid lines
it could be the emulator (android version, display size, resolution, ...)
if you can supply some details on the vm
may be i can arrange some testing

as for the sorting i'm sorry
i thought i've already answered
i'm doing some test
to decide if add it or not

stefanobusetto · Jun 21, 2013

@aviario
Now you can set the height of each row
with PropSetHeight ( Row , Height )

stefanobusetto · Jun 21, 2013

@magi6162
i've added fast scroll
set FastScroll = True to enable
it is disabled by default

stefanobusetto · Jun 23, 2013

Do you mean the grid or the grid lines?
What do you mean the grid is link to cursor?

stefanobusetto · Jun 24, 2013

@magi6162
your code looks ok.
here attached the test program i use to debug the grid.
can you try if it works and if you can see the grid please?
the app creates a local database and loads the grid with
the CursorAppend method.
ciao

stefanobusetto · Jun 25, 2013

don't worry pal
we'll get the hang of it
may you send a sample db
and the layout please?

aviario · Jun 25, 2013

hello, the version 2.07 has an error when I put
Cgrid.GridCreate2 (True) does not show the grid
Cgrid.GridCreate2 (False) works Ok.
