I'm drawing my indicator panel. I have a question, how to make it non-transparent for other lower graphical objects.

Some lines jump out (the mouse catches) and try to change their position.

In general, how to make the panel is not visible to the objects that it covers?

I'm not exactly sure (as it looks like you're creating your panel using the library) - if possible, you should give the panel a higher priority on receiving mouse clicks with this function

ObjectSetInteger(ChartID(),name,OBJPROP_ZORDER,z_order);

Two statements:

Print: 22.33

И

Print: 2.00000

Why are there different outputs? In C / C ++ the above statement works fine.

even in C, formatting

"%.*lf"

slightly different from what you imagined :-)

the first argument is precision (it's like an asterisk there), you probably thought the opposite, and getting "2.0000" you're surprised

PS/ don't learn MQL programming.

It doesn't matter library based or just object = OBJ_RECTANGLE_LABEL. Covering graph objects below the level, doesn't work.

I remember there was a time, screwed around a bit over it)))

In general, the principle is this.

I remember there was a time when I was struggling with this))

A variant of the finished one:

Basically, the principle is this.

Thank you! The principle is clear, I'll use it further!

The mql5 chm handbook does not work correctly for some reason. When I select this or that page, it doesn't show anything. What could be the reason and how to fix it?

It is necessary to remove the lock in the file properties.

Please help. I have a tick indicator. For some reason it shows the value in 4 digits, but I need it in 5 digits.
