ListView bug

[benohb]

Code: Pascal  [Select][+][-]

1. ListView1.ViewStyle:=vsIcon;
2.  ListView1.MultiSelect:=true;

Then try to Select the elements with Square-[/size]Select
All controls in form freeze

Then try to Select the elements with Square-Select

I don't understand what you are trying to say, or why you felt the need to set Select to 2px in size!!

There is a problem in ListView with GTK .


try this


ListView1.ViewStyle:=vsIcon;
ListView1.MultiSelect:=true;


The program will freeze when you want to select multiple icons

Using gtk2 in Linux Mint 18, Laz trunk, fpc 3.0 I cannot confirm this.

I can not confirm this with GTK2 on Raspbian armhf FPC 3.1.1/Laz 1.7

Thank you for test
But Try click on any button or write something in (edit1) . After selecting icons in ListView1
Please check

[Thaddy]

I can replicate this now, indeed,
The  first time I select a few icons and change focus to button or edit everything worked.
Change focus to listview a second time, select again, everything freezes.
Also note the listview does not keep (visual?) state between focus changes in GTK2.
I don't know if that is intentional.

Thaddy.
Yes, this is the problem (focus)
Thanks For verification

I found a work-around:


procedure TForm1.ListView1Click(Sender: TObject);
begin
 ListView1.Enabled:=False;
 ListView1.Enabled:=True;
end;
