Questions from Beginners MQL4 MT4 MetaTrader 4 - page 192

[Andrei Sokolov]

And is it possible to use a font that is not in MT? I need Montserrat.

[Nauris Zukas]

Good afternoon!

How is error 132 caught? Only by GetLastError() or by MarketInfo(Symb,MODE_TRADEALLOWED) also?

Afternoon. I am using the function (see below). Can't figure out how to make a flag to be formed only in case of 2 pending (up and down)

Andrey Sokolov:

Greetings

Could you please tell me if it is possible to set font thickness on text objects?

FoundTextSetFont (Sets font for text output by drawing methods)https://docs.mql4.com/ru/objects/textsetfont

, which has flags to set font thickness, but can't figure out how to use it.

This is for the TextOut function. You could try setting the font name plus " Bold", in your case "Montserrat Bold".

Can you tell me how to draw a "Button" object with transparency without using third-party libraries?

I couldn't find it on the forum

On a canvas to draw on.

[Vitaly Muzichenko]

Artyom Trishkin:

Draw on the kanvas.

Is there an example in the documentation of how to get the state "Pressed/Unpressed"?

From a drawn button? I haven't looked for one - I don't know. It's easier for me to make one myself.

Thanks, so I'll draw a classic one, I know how to work with it.

I would try to take a resource fromCBmpButton and apply transparency to the resource, it should probably work
