delphi - Color VirtualStringTree rows with hidden nodes -

-

I am currently using this code in my code's OnBeforeCellPaint event: 

  If node. Index mod 2 = 0 then start TargetCanvas.Brush.Color: = clBlack; TargetCanvas.FillRect (CellRect); End and Start TargetCanvas.Brush.Color: = clPurple; TargetCanvas.FillRect (CellRect); End;

To paint my nodes but it does not work with hidden nodes because the index remains the same. Is there a visible index or an easy solution?

Thanks in advance.

There is no such method to obtain the visibility node index at this time But you can make your own, where you repeat through visual nodes and calculate each iteration. Something like that (how do you apply it to the actual code on you):

function GetVisibleIndex (tree: TBVVertualTree; node: Piviular Node): Integer; Var P: P Virtual Node; Start (start the assigned (node), 'node should not be zero!'); Claim (tree. Asi [node], 'node should be visible!'); Results: = 0; P: = Tree. GetfirstSwibel; While assigned (P) and (P & lt; & gt; node) Ink (results); P: = tree. Guttaption utility (P); End; End;

In advance thank you If you have created a true asset in your class then You should be a great and setter, you can add the code directly to the form property in order to take action on the basis of "form": Public partial category Form 1: form {public form 1 () {InitializeComponent (); } // define car square public class car {public string name = string. Empty; } // private car to keep the value of the current car private variable _car = null; // Property of public form which you can ru...
