TElXTree scrollbar bug

Yuriy Schulga

I found that the horizontal scrollbar is not
displayed correctly in the ElXTree components and its derivatives when using
some VCL styles.

I also use the HighlightAlphaLevel=100 property.
And with light VLC Styles it looks like this:

That is,
the text disappears from the second and third columns.

Dark styles
seem to display everything correctly.

In addition, the plus/minus is not drawn from the VCL style.

And one more remark, if I may. In ElXTree.pas in lines 6899-6909, when you change the code to the one below, the appearance looks better:

      if HasFocus then

      begin

        if UseVCLStyles then

          LFill := VclStyleServices.GetSystemColor(clHighlight)

        else

          LFill := FOwner.FocusedSelectColor;

      end

      else if not FOwner.HideSelection then

      begin

        if UseVCLStyles then

          LFill := VclStyleServices.GetSystemColor(clHighlight)

        else

          LFill := FOwner.HideSelectColor;

      end;
