How to update MML5/logs file without closing the terminal - MQL4 and MetaTrader 4

Igor Makanu:

I haven't used SB for a long time, I don't remember half of it, but try making a software selection and deselecting by doing ChartRedraw() of the OBJ_EDIT object each time, you can get the names of the objects from SB, there must be a Name method

what if?

HH: and Sleep() is probably needed for ChartRedraw() , but Sleep() does not work in indicators

If you mean to make the object property OBJPROP_SELECTED TRUE, this is not the case. Because in this case the object will be highlighted on the chart, but the input box will not become active.

checked on all panels, it doesn't work highlighting the OBJ_EDIT object

I don't know, search the forum:

"tab"

"input focus"

Is there any way to update the MQL5/logs/*.log file without closing the terminal? To view its fresh contents.

right-click in the terminal in the context menu - open , this allows access to the log file

not conveniently done

Maksym Mudrakov:

The graph has two objects of type OBJ_EDIT

The goal is to make the transition between these two input fields by pressing Tab.

The main problem is not reading the keyboard event, but how to make the input field active programmatically.

I understand that you need to use user32.dll, but since I'm not good at it, please help.

Thank you.

The solution is found:

MQL5, ObjectCreate doesn't draw anything, objects don't even appear in object list. Creation is done at OnInit, maybe that's the problem?
At the same time, if we remove the robot from the chart, the created objects will be displayed

objects don't appear on How can I "hide" Remove text from chart

It's possible that the price and time for the object coordinates are equal to zero. Check it this way: Press Ctrl+B, in the dialog box that appears, press the "All" button and look at the list of existing objects. If there is one, open properties and see coordinates.

Objects disappear Object Selection without Right-Click object create arrow

At what point do you have to right-click?
