[SOLVED] Cannot compile Virtual TreeView 4.8.7 using FPC 2.6.1
« on: July 05, 2012, 03:17:21 pm »
Hi there everyone,

After upgrading from Lazarus 1.1 svn 37469/FPC 2.6.0 Win32 to Lazarus 1.1 svn 37865/FPC 2.6.1 Win32, I can no longer compile and install Virtual TreeView 4.8.7

The compiler errors are as shown below:

C:\Lazarus\components_extra\virtualtreeview\virtualtreeview 4.8.7 LCL R1\VirtualTrees.pas(1018,20) Error: No matching implementation for interface method "IDropSource.QueryContinueDrag(LongBool,LongWord):LongInt; StdCall;" found
C:\Lazarus\components_extra\virtualtreeview\virtualtreeview 4.8.7 LCL R1\VirtualTrees.pas(1018,20) Error: No matching implementation for interface method "IDropSource.GiveFeedback(LongWord):LongInt; StdCall;" found
C:\Lazarus\components_extra\virtualtreeview\virtualtreeview 4.8.7 LCL R1\VirtualTrees.pas(1214,14) Warning: An inherited method is hidden by "TVirtualTreeColumn.Equals(TObject):Boolean;"
C:\Lazarus\components_extra\virtualtreeview\virtualtreeview 4.8.7 LCL R1\VirtualTrees.pas(1311,14) Warning: An inherited method is hidden by "TVirtualTreeColumns.Equals(TObject):Boolean;"
C:\Lazarus\components_extra\virtualtreeview\virtualtreeview 4.8.7 LCL R1\VirtualTrees.pas(2458,15) Warning: An inherited method is hidden by "TBaseVirtualTree.SetVisible(PVirtualNode,Boolean);"
C:\Lazarus\components_extra\virtualtreeview\virtualtreeview 4.8.7 LCL R1\VirtualTrees.pas(2674,15) Warning: An inherited method is hidden by "TBaseVirtualTree.FontChanged(TObject);"
C:\Lazarus\components_extra\virtualtreeview\virtualtreeview 4.8.7 LCL R1\VirtualTrees.pas(3867,1) Fatal: There were 2 errors compiling module, stopping


Does anyone know if this has been solved in the SVN version?

Thanks,

JD
