 |
|
I have a question about listview with vertical scroll bar. How to get row number by clicking on the listview SubItems, if listview.RowSelect = false?
How to place the Edit box in the right place in the listview, if listview has a vertical scroll bar? Because after we move the scrollbar, the location of the Edit box should change accordingly after we click on the listview again.
Example: listview with 60 rows and 16 columns. ListView displays 60*16=960 1-byte values. (CEListView1 ViewStyle = vsReport; CEEdit1 BorderStyle = bsNone)
This code works if listview.RowSelect = true :
| Code: | UDF1_CEListView1.OnMouseDown = function(sender, button, x, y)
local i
local xpos=0;
local edit = UDF1_CEEdit1
for i=0, sender.Columns.Count-1 do
if sender.Columns[i].Visible then
local start=xpos;
local stop=xpos+sender.Columns[i].Width
if (x>=start) and (x<stop) then
--print("clicked on column "..i)
local Ind=sender.ItemIndex
edit.Visible = true
if i == 0 then --if 1-st column clicked
edit.Text = sender.Items[Ind].Caption
else
edit.Text = sender.Items[Ind].SubItems[i-1]
end
edit.Tag = Ind*0x10+i --0x10 = row
break
end
xpos=stop
end
end
if sender.ItemIndex ~= -1 then
edit.Left = sender.Left+3+xpos
edit.Top = sender.ItemIndex*14+sender.Top+22
end
end
UDF1_CEButton1.OnClick = function(sender)
local items = UDF1_CEListView1.Items
for x = 0, 59 do
local offset = 0x9CEF7C+x*0x10
local item = items[x]
item.Caption = readBytes(offset)
for y = 0, 14 do
local val = readBytes(offset+1+y)
item.SubItems[y] = val
end
end
end |

listview.TopItem is the item at top, use that to calculate the rest

Thanks, it works. This calculation is used in the code:
| Code: | edit.Top = (sender.ItemIndex-sender.TopItem.Index)*14+sender.Top+22
