TListView set selected item

[felipemdc]

Hello,

Is anyone having success in selecting the item of a TListView?

In my code I clear it and add some items and then try to set the selected item with:

  listCountries.ItemIndex := 0;

or

  listCountries.Selected := listCountries.Items[0];

But neither works =/

Both works here on Qt4: Lazarus 0.9.31 r35805M FPC 2.5.1 x86_64-linux-qt
I didn't test elsewhere.

[felipemdc]

My test was in Win32

[Blaazen]

It works on GTK2-appearance as well.

[Vingadero]

Working here on Win64 too...

Do you mean that the item is not highlighted as selected?  Make sure you do SetFocus for the listview.

It is working without problem on the Carbon widgetset on Mac OS X.

The first line

listCountries.ItemIndex := 0;

works as is, the second line has to be formulated as

listCountries.Selected[0] := true;

I currently also work on SELECTING AN ITEM of a TListView.

- Lazarus 1.4.0
- Windows 7 64 Bit

But both types of call such as ..

Code: [Select]

listCountries.ItemIndex := i;

Code: [Select]

listCountries.Selected := listCountries.Items[i];
do not work for me. ... 

[wp]

But both types of call such as ..
- listCountries.ItemIndex := i;
- listCountries.Selected := listCountries.Items[ i];

do not work for me. ... 

Hey - no need to get angry!

Both calls depend on the value of i which  must be >= 0 and < listCountries.Count.

works for me

Code: [Select]

  ListBox1.ItemIndex := SpinEdit2.Value;
or [code]
  ListBox1.Selected[SpinEdit1.Value] := True;
[/code]if you have multiselect set to true this one can be used to select multiple items.

Hm ...   ??!??!??!??!??!??!?


The combination of

      ListView.ItemIndex:= i;
      ListView.Selected;

did the job now.


BUT WHY ???????????????????????


For me this does NOT make any sense.
Can this be found in the documentation this way ?

Does this also work under DELPHI this curious way ?


Thanks,
Peter

This is certainly not correct, one of them is enough - see attached demo.

[PeterX]

Sorry, I'm on the job and can't test the demo code.


On (only)

   ListView.ItemIndex:= i;

nothing happens in my app .. :-(


I will try this evening, probably there's some buggy things to find in my code ;-)

Because ListView is not focused, try to focus ListView with the SetFocus method. Alternatively you can set HideSelection property to False.

[PeterX]

From the old Delphi version of my program the

.SetFocus()

method call was already there.
But didn't work, doesn't work, I'm sorry.
