I'm trying to use helper "iexMetaXelpers" and I see the error
"NewGridFromIPTC is not member of TStringGrid"

I added
# include <iexMetaXelpers.hpp> in H-file

1) What I should make to fix this issue?
2) Is there ability to make the same things without helpers?

Hi Vjacheslav

For 8.1.2, which should be ready before December (awaiting release of Rio), we have added global methods that can be used as an alternative to helper classes.

Sorry Vjacheslav,

We had to remove this from 8.1.2 due to difficulties with it on some Delphi versions. We will investigate it further and try to get it back into 8.1.3.

Was this feature added in ImageEn 8.3.0?

Hi

We investigated it, but decided the amount of work required to make it compatible with pre-Delphi 2005 versions was too significant. Apologies for this.

You should pull out the code you need until your own unit and convert it to a non-helper method.

Could you send an example based on "iexMetaXelpers" function?

Here's an example of converting a helper function to a global function...

HELPER METHOD:

procedure TListViewHelper.InitializeList(bFixLayout : Boolean = True);
const
  Buffer_px = 4;
var
  aListColumn: TListColumn;
begin
  Clear;

  if bFixLayout then
  begin
    ViewStyle := vsReport;
    Columns.Clear;
  end;
         
  // Clear content
  Clear;

  // Setup the columns
  if Columns.count < 2 then
  begin
    aListColumn := Columns.Add;
    aListColumn.Caption := iemsg(IEMSG_NAME);
    aListColumn.Width := Width div 3;      // 1/3 width
    aListColumn := Columns.Add;
    aListColumn.Caption := iemsg(IEMSG_VALUE);
    aListColumn.Width := MulDiv(Width, 3, 2) - GetSystemMetrics(SM_CYVSCROLL) - Buffer_px;  // 2/3 width less Scrollbar width
  end;
end;



GLOBAL METHOD:

procedure InitializeList(var aListView: TListView; bFixLayout: Boolean = True);
const
  Buffer_px = 4;
var
  aListColumn: TListColumn;
begin
  with aListView do
  begin
    Clear;

    if bFixLayout then
    begin
      ViewStyle := vsReport;
      Columns.Clear;
    end;

    // Clear content
    Clear;

    // Setup the columns
    if Columns.count < 2 then
    begin
      aListColumn := Columns.Add;
      aListColumn.Caption := iemsg(IEMSG_NAME);
      aListColumn.Width := Width div 3;      // 1/3 width
      aListColumn := Columns.Add;
      aListColumn.Caption := iemsg(IEMSG_VALUE);
      aListColumn.Width := MulDiv(Width, 3, 2) - GetSystemMetrics(SM_CYVSCROLL) - Buffer_px;  // 2/3 width less Scrollbar width
    end;
  end;
end;
