Re: [Oorexx-users] A strange behavior of the listview function

Hi,
the reason for this behaviour is the following routine:
::method onCheckboxChanged unguarded
expose Column.
use arg id, itemIndex, state
itemIndex += 1
say ID 'Checked row:' itemIndex Column.itemIndex.2 'state:' State
Column.itemIndex.4 = State
return 0
Any time a row is added this method is executed.
And here the cat biting in its own tail : list~check() cannot run before
list~addrow and list~addrow change indirect my parameter.
Any hint to solve this problem in a more elegant way than using a temporary
parm?
Regards
Roger

Hello,
currently I fight with the listview function. My first try was:
::method initDialog
expose Column.
-- Get a reference to the list view.
list = self~newListView(IDC_LISTVIEW)
list~addExtendedStyle("FULLROWSELECT GRIDLINES CHECKBOXES HEADERDRAGDROP")
list~insertColumn(0, "Select", 25)
list~insertColumn(1, "Column Name", 75)
list~insertColumn(2, "Column Type", 45)
do i = 1 to Column.0
trace ?i
say column.i.2 column.i.3 column.i.4 column.i.5
list~addRow(i, , , Column.i.2, Column.i.5)
If column.i.4 = 'CHECKED' then list~check(i-1)
say column.i.2 column.i.3 column.i.4 column.i.5
end
The trace output show this:
292 *-* say column.i.2 column.i.3 column.i.4 column.i.5

After one hour changing, reading, traceing I changed the source to this:
do i = 1 to Column.0
trace ?i
say column.i.2 column.i.3 column.i.4 column.i.5
if column.i.4 = 'CHECKED' then kk=1
else kk=0
ff=i-1
list~addRow(i, , , Column.i.2, Column.i.5)
If kk = 1 then list~check(ff)
say column.i.2 column.i.3 column.i.4 column.i.5
end
and got this trace output:
292 *-* say column.i.2 column.i.3 column.i.4 column.i.5
>C> COLUMN.I.2 => "COLUMN.1.2"?

The question is: what changed the value of column.i.4 from CHECKED to
UNCHECKED in the first source???
In my opinion both routine should work in the same way, but they dont.
Is this a bug or where is my mistake?

Roger
