Code to arrange charts

[fxsquirrel]

Hi,

I'm writing a script to setup a workspace. From the main toolbar, if you select "Window" you get a dropdown list. I can't find the functions that perform these actions. Do they exist?

Tile Windows

Cascade

Tile Horizontally

Tile Vertically

Also is there any code to minimise and maximise a chart window?

Thanks.

I have this script for vertical cascade-like arrangement.

It is calibrated for 4 charts on a FHD screen. It's for MT5, for MT4 I think handles had to be declared as longs.

Hey thanks for this, I'll have a go amending this for MQL4.

Don't think, read the documentation and be sure:

Returns the chart ID of the chart next to the specified one.

long  ChartNext(
   long  chart_id      // Chart ID
   );   

         ChartNext - Chart Operations - MQL4 Reference

Then write self-documenting code

#define CHART_ID long
   #define CHART_INVALID (CHART_ID) -1
