Subject: [Lazarus] TVirtualStringView (new trunk) and issues with items display
>Hello,
>I have created the demo of TVirtualStringView from the wiki (with few changes), and when I compile it, it just display the first char of the caption of each item, rather then the whole string.
>By Using gdb, I found out that on the TVirtualStringView side, the FOnGetText(Self, Node, Column, TextType, Text); line (VirtualTres.pas, line 31376) have only one char, while on the original code it does have the full string.
>I tried to convert the string (It's only ascii a-z0-9) to UTF-8 thinking that's the problem, but it is not.
>I'm using Lazarus 0.9.31 r30000M FPC 2.5.1 x86_64-linux-gtk 2
>Is there a bug in the new component, or am I doing something wrong ?
I just tried to install VirtualTreeView for the first time and I get these warnings and 1 error:
