I'm thinking to combine the code with /src/ui/win/win_ui.h file where we use structures to store data instead of tuples. Reading such code is very difficult so we might need to use the same idea in this class.

We could move structures from win_ui.h file into src/ui/ui.h. The only thing missing is we need an integer value instead of 3 uint8_t values for color.

We could do the same as it's done for Win32: just calculate RGB value during drawing (add a function at the top of the file to do such).

Ok, it sounds good. I'll do this.

Hi @fullset could we move these identical structures in a common location as src/ui/ui.h file to avoid code duplication?

As I see, there are 2 structures PointToDraw and LineToDraw which are almost identical in x11 and win_ui. And there are no problem to combine them.
But EllipseToDraw structures in x11 and win_ui have different semantics. In win_ui we specify top, left, right and bottom coordinates but it x11 we specify top, left coordinates and width and height. I could make common constructor of 4 doubles but I'm not sure that it's right decision. What do you think?

Let's stick to one design which should have top-left coordinate and width with height. For Windows during drawing we could easily find right and bottom values by adding width and height.

Hi, @ihhub.
It looks like I've broken windows building by my last changes but I can't find the reason because I haven't windows PC.

Could you put structures back in ui/ui.h but don't declare these variables:
std::vector<PointToDraw> _point;
std::vector<LineToDraw> _lines;
std::vector<EllipseToDraw> _ellipses;?

@ihhub
I've added 3 methods to
UiWindowX11class. I've made them similar todrawPoint()method.Also, I've slightly changed
drawPoint()method to draw the cross(x).Review please as you'll have a time.
