getmaxx & getmaxy in Lazarus

[oproescu]

Are there getmaxx and getmaxy functions in Lazarus? How are they used?
Thanks,

Excuse me for being stupid but what exactly does GetMAXX and Y pertain to

 I picture a lot of different possibilities ?

Returns in Turbo Pascal unit Graph the maximum screen resolution.

You can check that out for yourself:

Ok, I generally use SCREEN.... for that info.

 That is, if we are talking about GUI desktops

 Ok, So it looks like console mode..

That would clear things up, we need to specify these things.

Thanks julkas!
I researched https://www.freepascal.org/docs-html/current/rtl/graph/funcscreen.html and it appears that I knew this function from Pascal, but in Lazarus it generates the error: Identifier not found "getmaxx". Same with getmaxy.
How else can I find in Lazarus the maximum screen resolution?

As Jamie wrote, use Screen, which is a global instance of TScreen which encapsulates everything there is to know about the scree for GUI apps.

GetMaxX and GetMaxY belong to Unit Graph, as shown in the upper right corner of https://www.freepascal.org/docs-html/current/rtl/graph/funcscreen.html. Before you can use them, you must initialize the Graphic Mode via procedure InitGraph.
But I would use old unit Graph only in a console program. In a GUI program I would ask variable 'Screen' which belongs to Unit Forms.

Yes, Graph unit gives BP/TP compatibility.

I switched to PTCGRAPH unit.
Another *GRAPH unit - http://math.ubbcluj.ro/~sberinde/wingraph/.

Yes, Graph unit gives BP/TP compatibility.

The standard graph package already contains several different user sourcecode compatible implementations:
graph, ptcgraph, wingraph and sdlgraph, for example are all included.
To use one or the others, simply change uses clause....
