TElXTree scrollbar bug

Yuriy SchulgaYuriy Schulga
edited June 9 in LMD ElPack
I found that the horizontal scrollbar is not
displayed correctly in the ElXTree components and its derivatives when using
some VCL styles.image

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;

    I also noticed that when using VCL Styles and such code:

    Item.Cells[0].UseOwnStyle := True;
    Item.Cells[0].Style.Bold := True;
    Item.Cells[0].Style.ParentColors := False;
    Item.Cells[0].Style.TextColor := clYellow;

    the text color does not change, but is taken from style

    Incorporated into our code-base.

    This is not simple to handle, because initial idea for all controls is to ignore color properties and use colors from style instead. So, it actually work as it should.
