I try to after drags finished OBJPROP_SELECTED could be " false " with below code, no effects.
How can I solve it, please?
{
SL_TPdrags();
Sleep(1000);
drag_onoff=false; // OBJPROP_SELECTED
}
Thanks in advance.
Im sorry i never use CHARTEVENT_OBJECT_DRAG.
End of the day, I has been found " OBJ_RECTANGLE and OBJ_TEXT ", which one I am thinking I can use both of them instead of " OBJ_LABEL and OBJ_RECTANGLE_LABEL " that both of them moves together Bid line.
Q: So, which objects very useful for moves together Bid lines, please?
I am really need informative comment.
Have a nice weekend.

Unless you are testing sparam further up, that code triggers when any object is dragged.
My original code:
{
if(id==CHARTEVENT_OBJECT_DRAG && sparam=="line") // the chart event of dragging the line
I already know / read your one of great example CrossHair.mq4.
But I am struggling to give Bid price to Label, RectLabel Objects. Which is I am trying to Label, RectLabel Objects moves with Bid Line together.
I just need like image, please find attachment file.
All the best.
For the fixed-sized objects: OBJ_BUTTON, OBJ_RECTANGLE_LABEL and OBJ_EDIT, properties OBJPROP_XDISTANCE and OBJPROP_YDISTANCE set the position of the top left point of the object relative to the chart corner (OBJPROP_CORNER), from which the X and Y coordinates will be counted in pixels.

My original code:
{
if(id==CHARTEVENT_OBJECT_DRAG && sparam=="line") // the chart event of dragging the line
{
// here was my functions
}
That was not response to me.

But I use like below code which is I little change your code for me - and it works perfectly for me which one I want. So far I did not faced any problem.
Am I doing wrong, please?
All the best.
Perhaps this will help.
Add this to a chart and you will see:
