Hello I have this code for my test button:


int OnInit()
  {
      if(!ButtonCreate(0,InpName,0,150,150,200,100,InpCorner,"Press",InpFont,InpFontSize,
      InpColor,InpBackColor,InpBorderColor,InpState,InpBack,InpSelection,InpHidden,InpZOrder))
     {
     return(0);
    }

   ChartRedraw();

   return(INIT_SUCCEEDED);
  }

//+------------------------------------------------------------------+
//| ChartEvent function                                              |
//+------------------------------------------------------------------+
void OnChartEvent(const int id,
                  const long &lparam,
                  const double &dparam,
                  const string &sparam)
  {
//---
   if(sparam==bh) {
      Alert("dlcjwnd");
  }
}
//+------------------------------------------------------------------+

I hit the button and the Alert pops up all good.  But the button stayed looking pressed.  I also did this:

                Sleep(500);
                ObjectSetInteger(0,bh,OBJPROP_STATE,false);

That makes the button still work, but not self-unpress given that is what I've done with the button and my mouse click on it.

How can I get the button unpress-looking automatically, having clearly pressed-looking onClick?

ObjectSetInteger(0,bh,OBJPROP_STATE,false);

What does bh refer to? The button's name is InpName

Hello it is just because of the way it was pasted in - I've corrected the OP code.  The question still stands.

As you can see the SendKey function has the keydown and keyup so Windows/mql4 setup operates the hotkey button ok function-wise.  But on my chart, the button stays depressed.  I can click it again, and the script attached runs ok again, and the button undepresses, but this is not the functionality I want - obviously I was hoping to have the button undepress itself.

Where in your code do you re-set the button state?

Well after the sendkey statements I had the following, but the effect that had was to make it look like the button did not 'press'.  The effect of clicking it worked, but it didnt press and unpress, like a normal OS button.  Where should I put the ObjectSetInteger statement so it has the desired effect?


ObjectSetInteger(0,bh,OBJPROP_STATE,false)

Here, the code is supposed to pause and spread the actions out over time so I can see what is going on.

But the button doesn't ever look depressed, and the sleep calls are ignored.  Anyone know why this all doesn't work?

How should I manage a good user experience regarding depressing and undepressing buttons?

Right I see Sleep is ignored in Indicators.  I'll dig further and see where I can get a result with this.

Whatever you try to do it wont work with doubleclicks (or just too quick clicks) anyway.
