Hi,
I am trying to link buttons states according each other.
When I press (true) a button, all the others are unpressed (false).
bool TLR_Button_1_State       =ObjectGetInteger(0,"TLR_Button_1"       ,OBJPROP_STATE);
   bool TLR_Button_2_State      =ObjectGetInteger(0,"TLR_Button_2"      ,OBJPROP_STATE);
   bool TLR_Button_3_State=ObjectGetInteger(0,"TLR_Button_3",OBJPROP_STATE);

   //--- 1 button
   if(TLR_Button_1_State==true)
     {
      ObjectSetInteger(0,"TLR_Button_2"      ,OBJPROP_STATE,false);
      ObjectSetInteger(0,"TLR_Button_3",OBJPROP_STATE,false);
     }

   //--- 2 button
   if(TLR_Button_2_State==true)
     {
      ObjectSetInteger(0,"TLR_Button_1"       ,OBJPROP_STATE,false);
      ObjectSetInteger(0,"TLR_Button_3",OBJPROP_STATE,false);
     }

   //--- 3 button
   if(TLR_Button_3_State==true)
     {
      ObjectSetInteger(0,"TLR_Button_2",OBJPROP_STATE,false);
      ObjectSetInteger(0,"TLR_Button_1" ,OBJPROP_STATE,false);
     }

But it doesn't work.
Can you help me please ?

For me i have used the official standard source code given by mql for creating the buttons :

//+------------------------------+
//| tools                        |
//+------------------------------+
bool TLR_Button_Create(const long        chart_ID=0,   // chart's ID
                       const string            name="TLR_Button_",   // button name
                       const int               sub_window=0,   // subwindow index
                       const int               xx=0,                         // X coordinate
                       const int               yy=0,                         // Y coordinate
                       const int               width=30,                    // button width
                       const int               height=30,                   // button height
                       const ENUM_BASE_CORNER  cornerr=CORNER_RIGHT_LOWER,   // chart corner for anchoring
                       const string            text="TLR",   // text
                       const string            font="Arial",   // font
                       const int               font_size=7,   // font size
                       const color             clr=clrBlack,                // text color
                       const color             back_clr=C'236,233,216',     // background color

                       const bool              back=false,                  // in the background
                       const bool              selection=false,             // highlight to move
                       const bool              hidden=true,                 // hidden in the object list
                       const long              z_order=0)                   // priority for mouse click
                     //const color             border_clr=clrNONE;          // border color
  {
   //--- reset the error value
   ResetLastError();
   //--- create the button
   if(ObjectFind(chart_ID,name)<0)
     {
      if(!ObjectCreate(chart_ID,name,OBJ_BUTTON,sub_window,0,0))
        {
         Print(__FUNCTION__,
               ": failed to create the button! Error code = ",GetLastError());
         return(false);
        }

         //--- set button coordinates
      ObjectSetInteger(chart_ID,name,OBJPROP_XDISTANCE,xx);
      ObjectSetInteger(chart_ID,name,OBJPROP_YDISTANCE,yy);
         //--- set button size
      ObjectSetInteger(chart_ID,name,OBJPROP_XSIZE,width);
      ObjectSetInteger(chart_ID,name,OBJPROP_YSIZE,height);
         //--- set the chart's corner, relative to which point coordinates are defined
      ObjectSetInteger(chart_ID,name,OBJPROP_CORNER,cornerr);
         //--- set the text
      ObjectSetString(chart_ID,name,OBJPROP_TEXT,text);
         //--- set text font
      ObjectSetString(chart_ID,name,OBJPROP_FONT,font);
         //--- set font size
      ObjectSetInteger(chart_ID,name,OBJPROP_FONTSIZE,font_size);

         //--- set background color

   return(true);

Your way is very good.
I have tested it and it works very well.

I have to re-read it to understand it now.

Thank you very much.

When i change the time frame, the pressed button's state change to false (unpressed).
How can i fix it please ?

You would need to override and implement the CObject Load/Save in the chart buttons and also in the CArrayObj.

hello,
I just tried to add a color background and the editor told me that it's undefined .... why ? is "ColorBackground" not an inside keyword ?
      b.ColorBackground(clrGold);

In addition,
I have tried another way to get the same result by creatin the buttons in a loop, without "include" and "class".
void _Buttons_OutChart_Panel()
  {
    int _XPOSITION = 0;
    for(int _i=0;_i<4;_i++) // Creating Buttons in a loop
      {
        _XPOSITION+=_XSIZE_M;

        _Button_Create(0,
                       string(_i),
                       _Panel_Subwindow,
                       _XPOSITION,
                       _YPOSITION_Line1,
                       _XSIZE_M,_YSIZE,
                       _Panel_Corner_Buttons,
                       string(_i),
                       Font,
                       SizeFont,
                       _Button_Color_Unpressed_Font,
                       _Button_Color_Unpressed_Background,
                       false,
                       false,
                       false,
                       true,
                       1);
      }
  }


from this mql given code :

bool _Button_Create(const long        chart_ID=0,   // chart's ID
                       const string            name="_Button_",   // button name
                       const int               sub_window=0,   // subwindow index
                       const int               xx=0,                         // X coordinate
                       const int               yy=0,                         // Y coordinate
                       const int               width=30,                    // button width
                       const int               height=30,                   // button height
                       const ENUM_BASE_CORNER  cornerr=CORNER_RIGHT_LOWER,   // chart corner for anchoring
                       const string            text="",   // text
                       const string            font="Arial",   // font
                       const int               font_size=7,   // font size
                       const color             clr=clrBlack,                // text color
                       const color             back_clr=C'236,233,216',     // background color
                       const bool              state=false,                 // pressed/released
                       const bool              back=false,                  // in the background
                       const bool              selection=false,             // highlight to move

     {
      if(!ObjectCreate(chart_ID,name,OBJ_BUTTON,sub_window,0,0))
        {
         Print(__FUNCTION__,
               ": failed to create the button! Error code = ",GetLastError());
         return(false);
        }

         //--- set button coordinates

How can i get the desired state effect in a loop please ?

I am always searching a solution without success for now.

Perhaps you should try a tutorial on OOP... 


b.ColorBackground(clrGold);

...is not an "inside keyword", it is a call to a class method that does not exist. A method does exist for your desired result and it's also documented.
