[MSEide-MSEgui-talk] twidgetgrid onevent question

2013-03-20 Thread Patrick Goupell
In a twidgetgrid what is the purpose of onselectionchanged?  What, if 
anything, needs to be set to cause it to fire?

In the datacols.col what is the purpose of onselectionchanged?  What, if 
anything, needs to be set to cause it to fire?

Thanks.

Should be called if cell selection state of the grid changes.

Change the selection state of a cell of the grid.

Should be called if cell selection state of the column changes.

Change the selection state of a cell of the column.

For example the property tdatacol.selected can be used to change the selection 
state of a cell.

I guess that is not what I really wanted to know.

What I really want to know is in a twidgetgrid is there an onevent 
handler that will tell me when the twidgetgrid.row changes.

IE, the user has changed from row 5 to row 6.

[MSEide-MSEgui-talk] tsequencelink incorrect value assignment

2013-03-20 Thread Julio Jiménez
Sequence value is generated before tmsesqlquery.beforepost so if you cancel
post a value in the sequence is lost (unassigned)

I think the correct is to generate it after post and if the value is null
(dataset field value)

[MSEide-MSEgui-talk] About tmsesqlquery datasource propery

2013-03-20 Thread Julio Jiménez
What is tmsesqlquery.datasource for?

I have read mse db components are a fork of sqldb components. In sqldb,
zeos, ibx... this field is used for a master-detail relation but this mode
isn't working in mse

I know mse has tfieldfieldlink and tfieldparamlink, but simply assigning
datasourde of master dataset in detail dataset it easy.

Thanks.
