Questions from a "dummy" - page 31

Interesting:
Not pinpointed, it will draw in normal mode if the values are correct. In render mode there will probably be problems with BMP-graphics (I'm 90% sure).

At the weekend I was fiddling with the objects. If everything is not specified explicitly and unambiguously, begins to stumble - no objects, and no errors.

Silent:

Initialisation - inside the function, values - from global? Hmm.

From the help, for comparison

You're taking very literally what's written in the help. )) Initialization within function for local variables. I, on the other hand, initialized them globally.

I was fiddling with objects over the weekend. If you don't specify everything explicitly and unambiguously, it starts to stall - no objects, and no errors.

Did you manage to display BMP objects in visualization mode in the tester or not, I still don't understand? There is no problem with it outside the tester.

I.e., global values are used when names match? Is that correct?

PS add a redraw at the end though.

Answered above - haven't tried it, I'm not up to it yet. I just saw something in the code with which I didn't even draw objects, what bpm.

ChartRedraw(); set in correct places inside OnInit(), OnChartEvent() and OnTick() functions. I don't have any coincidence of names.))

The original question was not about the possibility to display graphical objects, but about the fact that in normal mode it happens, but not in visualization mode.

If you consider a function separately, it's just a function. Which, for example, can be stuffed into library and worked with from any place.

But the example from help shows rendering of object by script.

PS

As for the function itself, I think it lacks check of parameters for correctness (of course it is developer's personal opinion).

Also, I'd make type bool, not void (with error handling of object creation).

That's a good point. I'm just still in the process of studying mql4/mql5 and will improve the code as I go deeper into this environment)). Or until a rake hits me)).

So no values are assigned either.

So no values are assigned either. Where did you get the value?

I pass these object properties explicitly (ANCHOR_RIGHT_UPPER, CORNER_RIGHT_UPPER):

Create_BMP_Label(0,TI_bmp_nm,TI_bmp_pth,ANCHOR_RIGHT_UPPER,CORNER_RIGHT_UPPER,x,y);
