VirtualTreeView 4.8.7 LCL R2 released
« on: October 20, 2012, 04:57:33 pm »
I'm proud to announce the release of a new version of VirtualTreeView for Lazarus. This version is based on the 4.8 branch of the main repository

What's new
  • Compatible with Lazarus 1.0*
  • Support 64bit compilers
  • Improvements in drag and drop support
  • Performance improvements
  • Several bug fixes

* Recommended Lazarus 1.0.2 since it fixes a bug in hint window support (all widgetsets) and in wheel scrolling (gtk2)

Download the package file at Lazarus-CCR

It requires LCLExtensions 0.5

The demos can be found here

FAQ

1) Does it work in MacOSX (Carbon)?

I don't know since i don't have a MacOSX to test. Some users reported that it worked with some bugs. MacOSX users are encouraged to test and report the bugs preferentially with a test project.

2) Any plans to update to version 5?

Yes. As soon as feedback (and possible bugs) from this release comes, the work to sync with the new version will be started.

Perhaps you could give some more information on what goes wrong, e.g. Inidicating the error messages you see...

Hi LuizAmerico,

I have a strange problem with VTV, so the thing is, I'm using it in MacOS / Carbon (Luiz understand, you can not prove in Carbon) and fpc 2.6.2 works fine.
But I need to compile with svn 2.7.1 (09/01/2014) compiles fine, but I have a problem when selecting an item in the tree, you can play the demo "dataArray".

Specifically the exception occurs in VirtualTrees.pas

Code: [Select]
function TBaseVirtualTree.InternalAddToSelection(const NewItems: TNodeArray; NewLength: Integer;
  ForceInsert: Boolean): Boolean; 
...

    if FSelectionCount + NewLength >= Length(FSelection) then
     SetLength(FSelection, FSelectionCount + NewLength); //Exception Occurs here, where variables are FSelectionCount =0 and NewLength=1     
...


Luiz any ideas? Phil maybe?

Thanks!

Thanks Luiz! Work fine :):)

Code: [Select]
const
  {$I lclconstants.inc}

  {$ifdef Darwin}
  {$define PACKARRAYPASCAL} //for fpc 2.7.1
  {$endif}

  {$if defined(LCLGtk) or defined(LCLGtk2)}
    {$define Gtk}
  {$endif}
