OBJ_EDIT always on top?

Is it possible to set OBJ_EDIT graphical component always on top?

I'm currently able to show it on top for existing component ( for example it overlays a trendline ) but it doesn't work for new components ( the user is able to draw a new trendline which is drawn over the OBJ_EDIT component ).

I'm actually using ObjectSetInteger(0,objName1,OBJPROP_ZORDER,0); but it doesn't work for new components.

Thanks

The order of overlaying of the objects is their creation order. Probably the only way is deleting and re-creating the objects in the desired order. The Z-order applies to the mouse click events only (at least the docs say so).

Exactly!

Here's a workaround example which saves the OBJ_EDIT state to file, deletes the chart-object, creates it again, and loads the object state from file.

#property strict
#property indicator_chart_window
//+------------------------------------------------------------------+
#include <ChartObjects\ChartObjectsTxtControls.mqh>

class ForegroundEdit : public CChartObjectEdit
{
public:
   void BringToForeground()
   {
      string f = "temp/temp.bin";
      int h=-1;
      if(m_chart_id >=0)
      {
         h = FileOpen(f,FILE_BIN|FILE_WRITE);
         Save(h);
         FileClose(h);
      }
      ObjectDelete(m_chart_id,m_name);
      ObjectCreate(m_chart_id,m_name,OBJ_EDIT,m_window,0,0,0);
      h=FileOpen(f,FILE_BIN|FILE_READ);
      Load(h);
      FileClose(h);
   }
   void OnChartEvent(int id,string sparam)
   {
      if(id==CHARTEVENT_OBJECT_CLICK && sparam == m_name)
         EventKillTimer();
      if(id==CHARTEVENT_OBJECT_ENDEDIT && sparam == m_name)
         EventSetTimer(1);
   }
   void OnTimer()
   {
      BringToForeground();
   }
};
//+------------------------------------------------------------------+
ForegroundEdit edit;
int OnInit()
{
   edit.Create(0,"Foreground Edit",0,50,50,50,50);
   EventSetTimer(1);
   return(INIT_SUCCEEDED);
}
//+------------------------------------------------------------------+
void OnTimer()
{
   edit.OnTimer();
}
//+------------------------------------------------------------------+
void OnChartEvent(const int id,
                  const long &lparam,
                  const double &dparam,
                  const string &sparam)
{
   edit.OnChartEvent(id,sparam);
}
//+------------------------------------------------------------------+
int start(){ return 0; }
