Updating repo?

[PascalRiekenberg]

Are you going to update this repo with the changes of Virtual-TreeView/Virtual-TreeView?

Maybe it's a good idea to make Virtual-TreeView/Virtual-TreeView lazarus compatible. They are
willing to accept changes. See Issues of Virtual-TreeView/Virtual-TreeView.

The fpc compiler does not support the syntax used by current Delphi version.

It's possible but it will need to remove some features

[PascalRiekenberg]

Isn't there a common syntax for Delphi and Lazarus? Do you have sample of this Delphi-only syntax?

[blikblum]

The generic methods GetNodeData etc

[PascalRiekenberg]

Don't they work in fpc trunk? If not, they maybe can IFDEFed out for fpc .

[blikblum]

No. Trunk does not work

[PascalRiekenberg]

Okay, I see. You reported it in 2011 already :-(

After two years, any chance to see some updates in this repo? Is it impossible or do you need any help? Thank you very much.

[PascalRiekenberg]

The goal should be to update JAM-Software/Virtual-TreeView to make it work with Lazarus. But i do not have the time to do this. So help is welcome here.

[blikblum]

Unfortunately i know how to do but also do not have time.

Could you at least make a new official patch release containing all the Mac fixes with e.g. column drawing. The problem is Lazarus team is trying to ship their own Lazarus Treeview control, but as far as I know they do not contain any of the Mac paint glitches and column draw fixes.... It is a bit of a mess.... (And yes, they also seem to be ditching compability...)

@TommySlokky
Done

I will comment as testing the new download:

The lcl-extensions need the "cocoa" folder in "include" folder. Otherwise you get a compilation error. I can try email those that have been working.

I believe it correspons to this entry:

VirtualTrees.pas line 6082 fix

to
if (Tree Is TCustomVirtualDrawTree) and (Assigned(Node)) then
otherwise you get error: Operator is not overloaded: Class of TCustomVirtualDraw and Boolean

What compiler are you using?

Here with fpc 3.2.0 windows 32 bit it compiles fine
